[interprocess] Determine size of managed_shared_memory
by Kai Benndorf 12 Oct '19

12 Oct '19

Hi all, I want to create a managed_shared_memory in exactly the size I needed. Therefore I do something like this: size = sizeof( common_managed_shared_memory ); size += sizeof( MyClassInSharedMem ); managed_shared_memory segment(create_only, "name", size ); MyClassInSharedMem allocates itself some memory by segment->allocate(). I added this also to the size, but get a boost::interprocess::bad_alloc exception on allocating this additional memory. Are there some magic bytes I forgot to add? Many thanks in advance Kai

[statechart] Passing parameters from event to State Local Storage
by Christophe Bourez 16 Nov '16

16 Nov '16

I need to maintain a parameter into the state local storage. This parameter is initially contained in the event that causes the transition to the target state. I give hereafter a small illustrative example. typename sc = boost::statechart; class EvTest : public sc::event<EvTest> { public: EvTest(std::size_t val) : value(val) {} std::size_t getValue() const { return this->value; } private: std::size_t value; }; class MyStateMachine; class StSource; class StTarget; class StSource : public sc::simple_state<StSource, MyStateMachine> { public: typedef sc::custom_reaction<EvTest> reactions; sc::result react(const EvTest &event) { // How to pass event.getValue() to the target state ? transit<StTarget>(); } }; class StTarget : public sc::simple_state<StTarget, MyStateMachine> { public: StTarget(std::size_t val) : val(value) {} private: std::size_t value; }; Thanks, Christophe

Statechart serialization
by mbrodeur65 04 Mar '15

Hi, I'm looking for a solution to serialize boost::statechart objects. I'm aware that this feature is on the statechart library todo list but was wondering if there are any workaround to achieve this with the latest boost release (1.34) ? thanks for your help ! mbrodeur65 -- View this message in context: http://www.nabble.com/Statechart-serialization-tf4131326.html#a11749139 Sent from the Boost - Users mailing list archive at Nabble.com.

[Thread] Read-write locks
by lfrfly＠icqmail.com 17 Sep '14

17 Sep '14

I'm trying to create a standard read/write lock using Boost Threads, and I'm having a bit of difficulty mapping the Boost concepts onto the usual ones. A read/write lock should have several states: Locked for reading (multiple threads may lock at once), locked for writing (only one thread may lock, and no threads may be locked for reading at the same time), and unlocked. Ideally it would be nice if an RWL which is locked for reading may temporarily upgrade to locked for writing, then return to the locked for reading state. Boost supports several relevant notions of locking: shared locking, upgrade locking, and exclusive locking. This to me is a confusing distinction. In particular, a shared_mutex seems appropriate as the basis for a RWL, but is lock_upgrade() the equivalent of a write lock and lock_shared the equivalent of a read lock? This is unclear. If "upgrade locking" is not the same as "exclusive locking", then is an upgrade lock actually exclusive? Could someone please clarify this.

[Statechart] How to decide between post_event and process_event atrun time ?
by Philippe DAVID 22 Jul '14

22 Jul '14

Hi, I have a method in which I want to post/process an event. The thing is, this method can be called from outside the state machine (so I need to call process_event), or indirectly by a reaction of the state machine (in this case I must call post_event since process_event is not reentrant). I don't want to write 2 distinct methods to do this (one that calls post, and the other process), I would much rather prefer adding a 'if' in my method that tells me if I have to call process_event or post_event (if I'm being called indirectly by the state machine or not). Is there a way to do this with statechart ? regards, Philippe

[asio] resolver::cancel() problem
by Matthew Edwards 14 Mar '14

14 Mar '14

In my application (and a separate test program) it seems as though the cancel() function on the resolver does not work as intended. For async resolves, the cancel functionality should abort them immediately and pass an 'operation aborted' error code to the callback handler. In my tests, I will resolve an invalid domain (this causes the resolve to take a few seconds, to demonstrate the problem), sleep for 100ms, then call cancel on the resolver object. No cancelling actually occurs, and the callback is simply triggered after a few seconds with a "No host found" error code, not the expected operation aborted. Has anyone experienced this before, or know how I might be using the resolver incorrectly?

[BGL] Having a cost function as weight map
by Maxime van Noppen 06 Sep '13

06 Sep '13

Hi, I can't find how to do this pretty basic thing : having a function instead of a field to compute the cost of edges for various path finding algorithms. I couldn't find the answer in the documentation and Google was of no help. Did I miss something obvious ? Example : ------------------- #include <boost/graph/dijkstra_shortest_paths.hpp> #include <boost/graph/graph_traits.hpp> #include <boost/graph/adjacency_list.hpp> struct my_edge { double cost() const { return cost_ * 2; } double cost_; }; struct my_node { }; int main() { typedef boost::adjacency_list< boost::vecS, boost::vecS, boost::directedS, my_node, my_edge > graph_t; typedef boost::graph_traits<graph_t>::vertex_descriptor vertex_t; graph_t graph; vertex_t v /*= ... */; using boost::weight_map; // Works : boost::dijkstra_shortest_paths(graph, v, weight_map(boost::get(&my_edge::cost_, graph))); // Doesn't compile : //boost::dijkstra_shortest_paths(graph, v, // weight_map(boost::get(&my_edge::cost, graph))); } ------------------- Thanks ! -- Maxime

(I will use it though, so thanks) I can't guarantee where the boost libraries are installed, that's why I use FindBoost.

[Program Options] terminate parsing after first positional argument
by Stuart Pook 22 Jan '13

22 Jan '13

Hello, How can I tell Boost Program Options to stop parsing the arguments as soon as it finds a positional argument? I'd like to be able to parse the argument list "-v chmod -R -v 600 foo" as having one argument for my program (-v) and the rest as a std::vector of std::string (including the -v). In the attached program I have tried 2 different approaches. The first uses multitoken with the arguments "--command date -u -v", it fails because "-u" isn't known. The second uses collect_unrecognized with "chmod -R -v 600", it doesn't work because -v is interpreted by boost and doesn't end up in the vector. As someone said back in 2005, perhaps I'm trying to write xargs: http://thread.gmane.org/gmane.comp.lib.boost.user/9529/focus=9641 I know that I can ask my users to write a.out -v -- chmod -R -v 600 foo but I don't want to do that. I want them to write "a.out -v chmod -R -v 600 foo". The first positional argument should should tell boost to stop processing. Another slightly different question. If I have a multitoken option that takes doubles how can I get it to accept negative values? If I give my program "--floats 1 8 -4 6" where --floats starts a multitoken option that accepts double, I get an exception saying that "-4" is an unknown option. thanks Stuart This is what my test program gives me with boost 1.50: argv: dd --command date -u -v unrecognised option '-u' Allowed options: -v [ --verbose ] verbose --command arg command to run 2nd try argv: dd chmod -R -v 600 I'm verbose v: chmod -R 600 3rd try argv: dd --floats 1 8 -4 6 unrecognised option '-4' Allowed options: -v [ --verbose ] verbose -f [ --floats ] arg numbers and my program (formatted to fit in 80 characters) #include <boost/program_options.hpp> #include <boost/range/algorithm.hpp> #include <boost/program_options/parsers.hpp> #include <boost/program_options/options_description.hpp> #include <iostream> namespace po = boost::program_options; #define nelements(a) (sizeof (a) / sizeof (a)[0]) void print(char const * * b, char const * * e) { std::cout << "argv: "; std::copy(b, e, std::ostream_iterator<char const *>(std::cout, " ")); std::cout << std::endl; } int main(int argc, char ** argv) { { bool verbose; std::vector<std::string> command; po::options_description desc("Allowed options"); desc.add_options() ("verbose,v", po::bool_switch(&verbose)->default_value(false), "verbose") ("command", po::value<std::vector<std::string> >(&command) ->multitoken(), "command to run") ; char const * args[] = { "dd", "--command", "date", "-u", "-v", 0 }; print(args, args + nelements(args) - 1); po::variables_map vm; try { po::store(po::command_line_parser(nelements(args) - 1, args) .options(desc).run(), vm); po::notify(vm); if (verbose) std::cout << "I'm verbose\n"; std::cout << "command: "; boost::copy(command, std::ostream_iterator<std::string>(std::cout, " ")); std::cout << std::endl; } catch (boost::program_options::unknown_option & x) { std::cerr << x.what() << "\n" << desc << "\n"; } } std::cout << "2nd try\n"; { bool verbose; po::options_description desc("Allowed options"); desc.add_options() ("verbose,v", po::bool_switch(&verbose)->default_value(false), "verbose") ; char const * args[] = { "dd", "chmod", "-R", "-v", "600", 0 }; print(args, args + nelements(args) - 1); po::variables_map vm; po::parsed_options parsed = po::command_line_parser(nelements(args) - 1, args). options(desc).allow_unregistered().run(); try { po::store(parsed, vm); } catch (boost::program_options::unknown_option & x) { std::cerr << x.what() << "\n" << desc << "\n"; exit(2); } po::notify(vm); if (verbose) std::cout << "I'm verbose\n"; std::cout << "v: "; std::vector<std::string> v = po::collect_unrecognized( parsed.options, po::include_positional); boost::copy(v, std::ostream_iterator<std::string>(std::cout, " ")); std::cout << std::endl; } std::cout << "3rd try\n"; { bool verbose; std::vector<double> f; po::options_description all("Allowed options"); all.add_options() ("verbose,v", po::bool_switch(&verbose)->default_value(false), "verbose") ("floats,f", po::value<std::vector<double> >(&f)->multitoken(), "numbers") ; char const * args[] = { "dd", "--floats", "1", "8", "-4", "6", 0 }; print(args, args + nelements(args) - 1); po::variables_map vm; try { po::store(po::command_line_parser(nelements(args) - 1, args) .options(all).run(), vm); po::notify(vm); if (verbose) std::cout << "I'm verbose\n"; std::cout << "floats: "; boost::copy(f, std::ostream_iterator<double>(std::cout, " ")); std::cout << std::endl; } catch (boost::program_options::unknown_option & x) { std::cerr << x.what() << "\n" << all << "\n"; } } }

Further Boost.MPI development
by Matthias Troyer 15 Nov '12

15 Nov '12

Dear Boost.MPI users, With the MPI-3 standard having been finalized we want to intensify Boost.MPI development as soon as my crazy teaching schedule this fall gives me time from the middle of next month. With the deprecation of the - little used - official MPI C++ API in MPI-3 Boost.MPI has a chance of becoming a de facto standard C++ API for MPI. We first want to focus on features from MPI-2 and MPI-3 that are widely used or useful. For this purpose I would like to collect suggestions. Can you please reply and mention the functions of MPI that you would most like to see supported by Boost.MPI. Best regards Matthias

[Locale] MinGW + ICU + cross compiling = wchar errors?
by Jookia 12 Nov '12

12 Nov '12

Hello! I'm trying to compile Boost.Locale 1.51.0 with ICU 1.50 support in x86_64 MinGW-w64 4.7.2. So to start off, I have a structure of all my libs, includes and whatnot at /home/jookia/Programming/mingw64. I've built ICU using this command and installed it: CXXFLAGS=-fpermissive ../configure --prefix=/home/jookia/Programming/mingw64/ --host x86_64-w64-mingw32 --with-cross-build=/home/jookia/Programming/local/icu/source/build --enable-static --enable-shared --with-data-packaging=archive --with-library-bits=64 Building Boost uses this user-config: using gcc : 4.7 : x86_64-w64-mingw32-g++ : <rc>x86_64-w64-mingw32-windres <archiver>x86_64-w64-mingw32-ar <compileflags>-I/home/jookia/Programming/mingw64/include/ <linkflags>-L/home/jookia/Programming/mingw64/lib/ ; and this command: bjam threadapi=win32 target-os=windows variant=release threading=multi link=shared runtime-link=shared --prefix=/home/jookia/Programming/mingw64 --user-config=user-config.jam --without-python --without-mpi --layout=tagged -sNO_BZIP=1 -sNO_ZLIB=1 install In order to try and build Boost.Locale I've patched its Jamfile to remove the shared libstdc++ stuff as MinGW doesn't seem to support it, and also rename all of the searched-lib <name>s to their MSVC equivalents so I can find those. The command it used to build is this (stuff omitted to save space): "x86_64-w64-mingw32-g++" "-Wl,--out-implib,bin.v2/libs/locale/build/.../libboost_locale-mt.dll.a" -o "bin.v2/libs/locale/build/.../libboost_locale-mt.dll" -Wl,-h -Wl,libboost_locale-mt.dll -shared -Wl,--start-group ... -Wl,-Bstatic -Wl,-Bdynamic -licuuc -licuin -licudt -liconv -Wl,--end-group -L/home/jookia/Programming/mingw64/lib/ -mthreads Compiling works fine up until linking, where it gives a few errors like this (paths and mangled names omitted to save sapce): bin.v2/.../formatter.o:formatter.cpp:(... undefined reference to `icu_50::UnicodeString::UnicodeString(wchar_t const*, int)' Is there any solution to this or is this something to do with MinGW's lack of support for wchars? Thanks, Jookia.

[Filesystem] Reverse traversal of boost::filesystem::path::const_iterator?
by Nat Linden 02 Nov '12

02 Nov '12

I've stumbled across some code in our code base that wants to walk up a fixed number of containing parent directories from the starting path. (It's in a Mac application bundle nested within another.) boost::filesystem::path::[const_]iterator is described as bidirectional. But boost::filesystem::path has no rbegin() or rend(). In libs/filesystem/test/path_test.cpp's iterator_tests(), I see, for a path variable named itr_ck, use of boost::prior(itr_ck.end()). That suggests that usage of this form would be legal: path mypath = /* ...something... */; for (path::const_iterator rcomp(mypath.end()), rend(mypath.begin()); rcomp != rend; --rcomp) { // ... use boost::prior(rcomp) ... } Am I correct? Given the way some containers implement end(), I always feel nervous about decrementing end(). I'm happy to see that Boost.Filesystem's own tests guarantee that usage; but is there anything in the documentation that would have assured me of that?

Iterator Range, sub range of a desired size
by David Kimmel 01 Nov '12

01 Nov '12

Is there a function in BOOST, given a starting point and a desired size, that returns iterators for a (sub) range? For example, given: a boost::circular_buffer which contains: 1 2 3 4 5 6 7 8 9 10 a starting point which is an iterator pointing to 5 and finally a desired size which is an int s = 4 The result of which would be iterators producing: 5 6 7 8 A possible implementation might be this (but I was hoping there was a BOOST version since I can't find an STD algorithm) template <typename Itr> std::pair<Itr, Itr> getWindowDown(Itr begin, Itr end, Itr start, const int windowSize) { // Down first, then up if need be const Itr bottom = (end - start > windowSize) ? (start + windowSize) : (end); const Itr top = (bottom - begin > windowSize) ?

bug of boost algorithm library or boost asio?
by kpzhang 01 Nov '12

01 Nov '12

Hi, Apologize if this is not the right place for this mail. This program (it has been narrowed down from a larger program) always crashes after compiled in vs2008 Release(Win32) mode under windows 7. I am not familiar with assembly code and don't know it's a bug of compiler or boost::ends_with or boost::asio::buffers_iterator. It can be compiled and executed with g++ in Ubuntu without any problem. People said it's very unlikely to be compiler's bug, but when compiled in debug moded(or disable optimization), the problem does disappear. I have been stuck with this problem for quite a few hours. Any help is appreciated. Thanks in advance. #include <iostream>#include <string>#include <boost/asio.hpp>#include <boost/algorithm/string.hpp> typedef boost::asio::buffers_iterator<boost::asio::const_buffers_1> iterator_t;typedef boost::iterator_range<iterator_t> range_t;static const std::string LINE_END_MARK = "\r\n"; int main(int argc, char* argv[]){ boost::asio::streambuf _buf; std::ostream os(&_buf); os<<"END\r\n"; iterator_t cursor = boost::asio::buffers_begin(_buf.data()); iterator_t end = boost::asio::buffers_end(_buf.data()); std::ostream_iterator<char> it(std::cout," "); std::copy(LINE_END_MARK.begin(), LINE_END_MARK.end(), it); range_t r(cursor, end); if(!boost::ends_with(r, LINE_END_MARK)) return 0; return 1;}

C++ Now 2013 Call for Submissions
by Hartmut Kaiser 31 Oct '12

31 Oct '12

---------------------------------------------------------------------------- C++ NOW CONFERENCE 2013 - Aspen CO, USA, May 13-17, 2013, www.cppnow.org ---------------------------------------------------------------------------- CALL FOR SUBMISSIONS -------------------- We invite you to submit session proposals to the 2nd annual C++ Now Conference (Aspen CO, USA, May 13-17, 2013). Building upon the resounding success of C++ Now 2012 and five years of BoostCon, C++ Now 2013 will present leading speakers from the whole C++ community. The C++ Now Conference is dedicated to discussion and education about C++, an open and free language and standard. Our Conference will focus on discussion and education about open source software usage and developments in the C++ developer and user community. To reflect the breadth of the C++ and Boost communities, the conference includes sessions aimed at three constituencies: C++ and Boost end-users, hard-core Boost library and tool developers, and researchers pushing the boundaries of computation. The program fosters interaction and engagement within and across those groups, with an emphasis on hands-on, participatory sessions. As a multi-paradigm language, C++ is a melting pot where the most compelling ideas from other programming communities are blended in powerful ways. Historically, some of the most popular sessions at C++ Now have highlighted these concepts, from DSLs to functional programming to transactional memory and more. Bring your C#, Python, Ruby or Haskell influences to bear in an environment that will broaden their exposure. At C++ Now 2013 we would like to focus on parallel and distributed computing with C++. However, by no means this is intended to restrict the topics of proposals we hope to see. Any other topic related to C++ as outlined below is perfectly fine for submission. IMPORTANT DATES --------------- New proposal submissions due: December 15th, 2013. Proposals decisions sent (tentative program available): January 30th, 2013. Fully scheduled program available: February 24th, 2013. BEST PRESENTATION AWARDS ------------------------ We know how much effort it takes to prepare talks for our conference. For this reason we will award the best presentations in the following categories: Best Presentation, Best Short Presentation, Best Tutorial, and Best Workshop. The awards will be given based on the audience's voting. Each award will include the author's name listed on the cover of the C++ Now website for that year and a plaque containing all the C++ Now conference information. SESSION TOPICS -------------- Topics of interest include, but are not restricted to, the following: * Parallelism in the new C++11 standard * Parallel, distributed and GPGPU topics relating to C++ * C++11 and how it changes life for users and library writers * General tutorial sessions on C++11, the C++11 Standards library, and one or more Boost libraries * In-depth sessions on using specific Boost libraries * Case studies on using Boost * Experts panels * Advanced sessions on implementation techniques used within Boost libraries * Development workshops to extend or enhance existing Boost libraries * Workshops on design process * Infrastructure workshops such as Build tools, Website, Testing * Concepts and Generic Programming * Hardware and infrastructure presentations focused on how libraries can make better use of the technology * Software development tools and their application to C++ and or Boost * Other topics likely to be of great interest to C++ users and developers Interactive and collaborative sessions are encouraged, as this is the style of learning and participation that has proven most successful at such events. Sessions can be tutorial based, with an emphasis on interaction and participant involvement, or workshop based, whether hands-on programming or paper-based, discussion-driven collaborative work. SESSION FORMATS --------------- Presentations Presentations focus on a practitioner's ideas and experience with anything relevant to C++11, Boost and users. Panels Panels feature three or four people presenting their ideas and experiences relating to C++11 and Boost's relevant, controversial, emerging, or unresolved issues. Panels may be conducted in several ways, such as comparative, analytic, or historic. Tutorials Tutorials are sessions at which instructors teach conference participants specific skills relevant to C++11 and Boost. Workshops Workshops provide an active arena for advancements in Boost-relevant topics. Workshops provide the opportunity for experienced practitioners to develop new ideas about a topic of common interest and experience. Author's Corner Presentations These were introduced at BoostCon 2008, and were a great success. They are short (30 minute) sessions, focusing on tips on usage and design. In addition, we're looking to uncover the hidden design gems in Boost libraries. Tool Vendors Presentations We actively encourage tool vendors and ISP's to submit proposals for a special Tool Vendors Session Track aimed at products related to Boost and C++ (compilers, libraries, tools, etc.). Other formats may also be of interest. Don't hold back a proposal just because it doesn't fit into a pigeonhole. SUBMITTING A PROPOSAL --------------------- Standard Sessions are 90 minutes. You may submit a proposal for fractions Or multiples of 90-minutes. Fractional proposals will be grouped into 90 Minute sessions covering related topics. Longer sessions, such as tutorials and classes, will be assigned three hour (i.e. half day), or six hour (i.e. full day) time slots. Please include: * The working title. * Type of session: presentation, panel, tutorial, workshop, authors corner, vendor track, other. * A paragraph or two describing the topic covered, suitable for the conference web site. * Proposed length: 10-20 minute short talks, 45 minutes, 90 minutes, half day, full day. * Alternate lengths, if you are willing to make adjustments: 10-20 minute short-talks, 45 minutes, 90 minutes, half-day, full day. * Audience: users, developers, both. * Level: basic, intermediate, advanced. * A biography, suitable for the conference web site. * Your contact information (will not be made public). SUBMISSION DETAILS ------------------ All submissions should be made through the EasyChair conference management system: http://www.easychair.org/conferences/?conf=cppnow2013. If you have not already registered at EasyChair, you will need to do so in order to submit your proposal. All submissions will go through a peer review process.

lockfree is part of the boost-1.52?
by niXman 31 Oct '12

31 Oct '12

Hi, As I can see, lockfree is in trunk, but in the documentation for boost-1.52 is not said about that. Why? And one more question: How can I determine what lockfree is part of the boost? Is there a macro for this? -- Regards, niXman ___________________________________________________ Dual-target(32 & 64-bit) MinGW compilers for 32 and 64-bit Windows: http://sourceforge.net/projects/mingwbuilds/

question on multi_index_container
by John M. Dlugosz 31 Oct '12

31 Oct '12

I created a multi_index_container in a way to emulate and enhance a std::set. That is, ordered_unique on some key extraction I specified. Like a std::set, inserting a "duplicate" will not do the assignment at all and the old value remains. However, what I want is for the new item to replace the old with the same key. Is there an easy or straightforward way to configure multi_index_container to do this?

(no subject)
by Yiğit Çağrı Akkaya 31 Oct '12

31 Oct '12

Hi, I have an MFC application. There are plenty of dll's written by us. In one dll module, we use boost. However, on start up of application, it throws several assertions about loading dll. I know assertions are available only for debug mode, but we want to get rid of every small problem in order to provide a stable release. I made web search and I found this thread: http://lists.boost.org/threads-devel/2009/06/0476.php This belongs to 2009 and Boost 1.39. We use Boost 1.48 and Visual Studio 2008 SP1. Thread says that this happens when MFC application statically linked to boost. Probably, nothing changed up to 1.48 because I found that line and commented it out(extern BOOL (WINAPI * const _pRawDllMain)(HANDLE, DWORD, LPVOID)=&dll_callback;). Is there a macro defined in boost to differentiate static and dynamic builds? If there is a macro, we are planning to wrap macro around that line. Or is there any better solution for this? Thanks in advance...

[phoenix] std::function doesn't work with phoenix ?
by Kamil Zubair 31 Oct '12

31 Oct '12

When I try to do this is VC++ 2010 : #include <functional> #include <boost\bind.hpp> #include <boost\phoenix.hpp> float Func() { return 1.f; } typedef std::function<float()> F; int main() { F f2 = boost::phoenix::bind(&Func); } It failed to compile, but when I change boost::phoenix::bind to boost::bind it compiled just fine. What's going on ? I thought phoenix::bind and boost::bind is interchangeable.

[Boost.Test] What's the best way to make custom assertions?
by legalize+jeeves＠mail.xmission.com 30 Oct '12

30 Oct '12

[Please do not mail me a copy of your followup] I want to make custom assertion methods that report the failure location as the place where the custom assertion is invoked, not the location where the BOOST_REQUIRE_xxx macros are used in the implementation of the custom assertion. In my own code, when I wanted to do report the point of invocation instead of the point of implementation, I implemented my code along the lines of void report(char const* file, int line) { // ... // output a message using line and file // ... } #define REPORT() report(__FILE__, __LINE__) void code() { REPORT(); // report something interesting here } When I look at how the assertion macros are implemented in Boost.Test, it seems that __FILE__ and __LINE__ are substituted down pretty far in the macro invocation chain. This means that if I want to write my own custom assertion that reports messages at the point of invocation and not at the point of implementation, I have to call these very low-level macro facilities and duplicate a bunch of stuff that's in Boost.Test. One thing I don't want to do is make a gigantic multi-line macro for my custom assertion. I really don't like using macros for things that could be done with functions and a custom assertion, IMO, falls into that category. Is there a clean way of implementing a custom assertion in the manner I've described without replicating a bunch of the intermediate layers of Boost.Test's macros? Gennady, if you're reading this and there isn't a clean way of doing what I'd like, are you willing to accept a refactoring changeset that promotes __FILE__ and __LINE__ arguments higher in the macro call chain? -- "The Direct3D Graphics Pipeline" free book <http://tinyurl.com/d3d-pipeline> The Computer Graphics Museum <http://computergraphicsmuseum.org> The Terminals Wiki <http://terminals.classiccmp.org> Legalize Adulthood!

[mpi] many undefined references to serialize<boost::mpi::detail::mpi_datatype_oarchive>
by Brian Budge 30 Oct '12

30 Oct '12

Hi all - I've got a class hierarchy that can already be serialized into text or binary archives. I'm explicitly instantiating the template functions for serialize and/or load/save. I'm trying to add the capability to have boost mpi perform the serialization through send/recv/broadcast. I've added explicit instantiations for the boost::mpi::packed_iarchive and packed_oarchive. My code compiles, but at the end I get a bunch of undefined references for serialize<boost::mpi::detail::mpi_datatype_oarchive>. I can add the explicit instantiations for this oarchive, and this seems to fix my linking issue, but this seems broken, i.e. I should not have to deal with anything in a boost::detail namespace? Is there another suggestion for how to get this to work? Thanks, Brian

[MPI] missing symbols using serialization's static library design
by Barrett, Brian W 30 Oct '12

30 Oct '12

Hello all - On Mac OS X Lion, we're seeing errors when linking our application using Boost.MPI. The application is rather large and uses Boost.Serialization for both checkpoint/restart and MPI communication. The checkpoint/restart bits made serialization a bit of a disaster in terms of compile times (due to headers including basically every other header in the project). To solve that problem, we followed the Boost.Serialization advice on static libraries, and all is good. Except that on Lion (and possibly elsewhere, but definitely on Lion) using the gcc front-end (i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.11.00)), we're seeing link failures due to serialization calls for MPI archivers not being found when compiling with -O2 or higher on Boost 1.50.0 and 1.51.0: CXXLD sst.x Undefined symbols for architecture x86_64: "void SST::Introspector::serialize<boost::mpi::packed_iarchive>(boost::mpi::packe d_iarchive&, unsigned int)", referenced from: boost::archive::detail::iserializer<boost::mpi::packed_iarchive, SST::Introspector>::load_object_data(boost::archive::detail::basic_iarchive &, void*, unsigned int) const in introspectedComponent.o boost::archive::detail::iserializer<boost::mpi::packed_iarchive, SST::Introspector>::load_object_data(boost::archive::detail::basic_iarchive &, void*, unsigned int) consti n simulation.o While I could simply explicitly insatiate the missing archivers, that seems like a bad idea for something in the detail namespace and it appears that the list of archivers I'd need to instantiate has changed over time. Is there a better solution to the problem? There's a test case the exhibits the problem available here on our Google code project bug tracker. It's essentially the Boost.Serialization demo_pimpl example, but using MPI instead of a text archiver. The code is at: http://sst-simulator.googlecode.com/issues/attachment?aid=280000000&name=mp i_serialization_test.tar.gz&token=1MTkBuFrhrfUUAZRZYH3kZrElIg%3A13500682075 60 Thanks, Brian -- Brian W.

[boost build] Where/How is python found?
by Gottlob Frege 30 Oct '12

30 Oct '12

I'm trying to determine how boost build finds the python install. I see in boost\tools\build\v2\tools\python-config.jam that it looks in the Windows Registry (for NT at least). But this only checks for Python 2.4, 2.3, 2.2. It also seems to look for python.exe in the PATH. But I can't seem to find the code that does that. Any ideas? In particular, I would like to change it to actually check for an include directory once it finds python.exe. On my system, it finds a 'rogue' python.exe that is not part of the full python install (thus no include folder). Tony

[Boost.Test] Always leaving test code active in Release mode
by Ruediger Berlich 30 Oct '12

30 Oct '12

Hi there, we use Boost.Test to do Unit tests for the Geneva library, covering parametric optimization. Code for tests is included directly in most classes, so tests can be written "on-site", whenever a new feature is added. However, in Release mode, usually test-functions are *not* included (masked by an "#ifdef GEMTESTING" block), but can be switched on by the user prior to compilation. When this happens, it means that classes being tested have a different interface than classes without the GEMTESTING-define set. Users are meant to derive their own classes from the Geneva's core classes and overload certain functions. They are also provided with a test infrastructure, that allows them to test their own code without too much trouble for compliance with the libraries rules (as just one example, it is being tested whether their code can be serialiazed using Boost.Serialization and whether de-serialized classes are identical to the one being serialized). However, when users compile our (Open Source) library with the GEMTESTING-define set and then compile their own code without this flag, they will include headers with a different interface than the one being used to compile the library. This has led to some very hard to detect failures. We are looking for ways to circumvent this source of errors and so far see three options: a) We can give compiled libraries a different name when the test-code is included (e.g. libgeneva-testing.so or the likes) b) There could be sanity checks in the code, e.g. with a static function returning different values depending on whether test code is activated or not c) We can always compile the test code, even in Release mode, by removing the "#ifdef GEMTESTING", this leaving no ambiguities regarding the API Option a) will effectively double compilation times, as we will always have to compile both library variants. It would also force us to make many changes in the CMake-based build system. Option b) leaves a source for frustration for our users, as they will only discover the problem when compiling and/or running their code. Option c) is the easiest to implement, but leaves open some questions (see below) *** My question now is, what the trade-offs of option c) are (i.e., leaving all test code in and always linking with the Boost.Test libraries). Do we loose anything ? Will this affect our ability to debug the code ? Are there runtime-penalties ? Note that none of the test-functions is called during normal execution. *** Of course any views on a good strategy for the above scenario are also appreciated. In any case thanks and best regards, Ruediger

Typedef rejected when disambiguating a call to boost::assign
by mark pashley 30 Oct '12

30 Oct '12

I am trying to initialise a std::map of std::set using boost::assign, as follows: typedef std::set< uint32_t > the_set_t; typedef std::map< uint32_t, the_set_t > the_map_t; the_map_t data = boost::assign::map_list_of< uint32_t, the_set_t > > // bad line ( 1, boost::assign::list_of(10)(20)(30) ) Unfortunately this is rejected by GCC 4.4.6, and results in a large amount of errors, (attached below). The problem is caused by the use of the typedef the_set_t. If the typedef is replaced with std::set<uint32_t> the code compiles and works correctly. the_map_t data = boost::assign::map_list_of< uint32_t, std::set< uint32_t > > The error produced is as

shared_ptr on aix
by Vojtech Fried 30 Oct '12

30 Oct '12

Hi, What is the status of boost/smart_ptr/detail/sp_counted_base_aix.hpp? It is not #included by default in sp_counted_base_aix.hpp. Is it safe to use or is it just an exprerimental version? We have a multiplatform application and I am trying to make some improvements for it on AIX platform. One candidate right now is to utilize sp_counted_base_aix.hpp (boost/smart_ptr/detail/sp_counted_base_aix.hpp). It implements atomic counter without (pthread) mutexes. Using it improves performance of our app up to 10%. But sp_counted_base_aix.hpp is not used by default. I had to add an #ifed to sp_counted_base.hpp to make it work. I tested the implementation with a small sample program that copied and removed shared_ptrs in multiple threads and it works. But I am still concerned. How widely is this AIX specific implementation used? How risky is it for us to use it? Best regards Vojtech

Boost.Test ordering
by John M. Dlugosz 30 Oct '12

30 Oct '12

If I make unit tests in different source files, I need to declare a BOOST_AUTO_TEST_SUITE in each one, right? At link time, these appear in some undetermined order. How can I cause them to be run in the desired order instead? —John

boost::container::vector fails to compile with C++03 compiler
by mark pashley 30 Oct '12

30 Oct '12

The following example compiles fine when using GCC 4.4.6 with the --std=c++0x flag but fails to compile in C++03 mode. #include <stdint.h> #include <boost/container/vector.hpp> struct data { int i_; boost::container::vector<data> v_; }; int main( int argc, char** argv ) { data myData; myData.i_ = 10; data myData2; myData2.i_ = 30; myData.v_.push_back( myData2 ); return 0; } It compiles successfully with g++ --std=c++0x test-cont.cpp However if I remove the --std=c++0x I get the following errors: g++ test-cont.cpp In file included from include/c++/4.4.6/memory:49, boost/container/container_fwd.hpp:36, boost/container/vector.hpp:20, from test-cont.cpp:2: include/c++/4.4.6/bits/stl_algobase.h: In static member function static _OI std::__copy_move<false, false, std::random_access_iterator_tag>:: __copy_m(_II, _II, _OI) [with _II = boost::container::constant_iterator<data, long int>, _OI = data*]: include/c++/4.4.6/bits/stl_algobase.h:397: instantiated from _OI std::__copy_move_a(_II, _II, _OI) [with bool _IsMove = false, _II = boost::container::constant_iterator<data, long int>, _OI = data*] include/c++/4.4.6/bits/stl_algobase.h:436: instantiated from _OI std::__copy_move_a2(_II, _II, _OI) [with bool _IsMove = false, _II = boost::container::constant_iterator<data, long int>, _OI = data*] include/c++/4.4.6/bits/stl_algobase.h:468: instantiated from _OI std::copy(_II, _II, _OI) [with _II = boost::container::constant_iterator<data, long int>, _OI = data*] boost/move/move.hpp:1147: instantiated from boost::copy_or_move(I, I, F, typename boost::move_detail::disable_if< boost::move_detail::is_move_iterator, void>::type*) [with I = boost::container::constant_iterator<data, long int>, F = data*] boost/container/detail/advanced_insert_int.hpp:58: instantiated from void boost::container::container_detail::advanced_insert_aux_proxy<A, FwdIt, Iterator>::copy_remaining_to(Iterator) [with A = std::allocator<data>, FwdIt = boost::container::constant_iterator<data, long int>, Iterator = data*] test-cont.cpp:21: instantiated from here include/c++/4.4.6/bits/stl_algobase.h:343: error: no match for operator= in * __result = __first.boost::container::constant_iterator<T, Difference>::operator* [with T = data, Difference = long int]() test-cont.cpp:5: note: candidates are: data& data::operator=(data&) It looks like boost::container::vector requires move semantics which I assumed would automatically use boost::move when compiled with a c++03 compiler. If I manually modify the struct data to define: a default constructor a copy constructor an assignment operator an emulated move constructor using BOOST_RV_REF an emulated move assignment operator using BOOST_RV_REF The example compiles. Having to manually add these move/copy constructors and assignment operators for C++03 is laborious.

Visual Studio Debugger "renderer" support for Boost.Container ?
by John M. Dlugosz 29 Oct '12

29 Oct '12

MS Visual Studio's Debugger comes pre-loaded with "renderers" (I forget what S.T.L. actually called them) for the containers and smart pointers supplied with the compiler. Looking at a Boost Container in the debugger is not nearly so nice. Has anyone looked into adding renderers for them?

Multiplying a matrix and vector ===> vector
by Vipin Varma 29 Oct '12

29 Oct '12

Dear all, My basic requirement is to multiply a matrix and a vector and then to store it into a vector using Boost's UBLAS. When I multiply a boost::numeric::ublas::compressed_matrix with a boost::numeric::ublas::vector using prod(matrix, vector), the output is a boost::numeric::ublas::matrix_vector_binary1. E.g. <PSEUDOCODE> boost::numeric::ublas::compressed_matrix m; boost::numeric::ublas::vector x; boost::numeric::ublas::matrix_vector_binary1<compressed_matrix, vector, ? > tmp; tmp = prod(m,x); <PSEUDOCODE> The problem is that in the third field --- which expects the operation type --- in line 3, I do not know what to enter or how to specify the type of operation; I tried '*' and 'prod' and 'vector' and 'compressed_matrix' but none work. Alternatively, I can avoid the tmp variable altogether and get a working program to copy the result of matrix-vector multiplication onto a new vector y but then I would need two multiplications. E.g. <CODE> std::copy(prod(m,x).begin(), prod(m,x).end(), y.begin()); <CODE> Any suggestions on how to declare a matrix_vector_binary1 correctly or how to get the finaly result efficiently onto a vector will be appreciated. Regards, Vipin

Hi, I’am using boost in my application. I need an explanation about build process and library creation. I’d know if there is an alternative to bjam, could I use a make file made by me? It’s difficult to implement a build process? The .lib files generated by b2 process are created from the source file contained in the archive file? Thanks. Best regards, Daniele.

[Thread] Win32 TLS problem with dynamic libraries
by Сергей Захарченко 29 Oct '12

29 Oct '12

Hello, I need to build a shared plugin library with Boost libraries linked statically into it. As many may know, there's a problem with having a .tls section in Win32 dynamic libraries which are to be loaded via LoadLibrary, but Boost.Thread insists on having one. Assuming that I can guarantee that no Boost.Thread functions are called from non-Boost.Thread threads, it shouldn't be needed. Apart from patching the Boost.Thread sources, or the resulting binaries, what's the best way of eliminating it? I assume that I need to eliminate tss_pe.cpp from linkage, but I don't seem to be able to. Adding a namespace boost { void tss_cleanup_implemented() {} } to one of the library's sources doesn't help, as it results in a multiply defined symbol error (compiler MSVC2008 from Express edition). Any suggestions? Thank you, -- Sergey Zakharchenko

Boost installation inquiry
by mega deth 28 Oct '12

28 Oct '12

Hello Boost User Community, I am a big fan of boost C++ having used it for a college class to do threading. I want to get back into it and I previously installed boost on a windows machine, now dealing with a Linux machine would like some help as I have run into difficulties with the installation process. First off, I would like to build threads and regex libraries. I have gotten the first example show below to work correctly: #include <boost/lambda/lambda.hpp> #include <iostream> #include <iterator> #include <algorithm> int main() { using namespace boost::lambda; typedef std::istream_iterator<int> in; std::for_each( in(std::cin), in(), std::cout << (_1 * 3) << " " ); } My main issue is the next part. I have Boost is located in /usr/local/boost_1_51_0 I have run the following steps: 1. Go to the directory tools/build/v2/. 2. Run bootstrap.sh 3. Run b2 install --prefix=PREFIX where PREFIX is the directory where you want Boost.Build to be installed 4. Add PREFIX/bin to your PATH environment variable. For the 3rd step, I ran b2 as follows: b2 --build-dir=~/bin/Boos tC++1.51/ toolset=gcc stage My PATH looks like this: > echo $PATH /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/root/bin :/root/bin/BoostC++1.51/bin/ g++ I- /root/boost/ /root/bin/repos/c-projects/c++/C++Projects/Boost/testLinkToBoostLib.cpp -o example \ > ~/boost/stage/lib/libboost_ libboost_chrono.a libboost_regex.a libboost_chrono.so libboost_regex.so libboost_chrono.so.1.51.0 libboost_regex.so.1.51.0 libboost_filesystem.a libboost_system.a libboost_filesystem.so libboost_system.so libboost_filesystem.so.1.51.0 libboost_system.so.1.51.0 libboost_program_options.a libboost_thread.a libboost_program_options.so libboost_thread.so libboost_program_options.so.1.51.0 libboost_thread.so.1.51.0 Finally this is my issue: When I try to compile the test regex code with boost, I am unable to find the correct library to include. I fear that because I have this issue, that my thread library is not built as well. Is there a way to check? Can you provide what worked for you to install boost on your linux machine. c++ -I path/to/boost_1_51_0 example.cpp -o example \ ~/boost/stage/lib/libboost_regex-gcc34-mt-d-1_36.a I am unable to find or even create this: libboost_regex-gcc34-mt-d-1_36.a If you have any advise or direction please let me know. Thank you! There was some talk about checking the configuration of the user-config.jam if there are linker or compile issues. But I do not think those could be the issues at the moment. Thank you in advance for looking at my issue! ~Jake

Boost random not looking so random
by Robin Rowe 28 Oct '12

28 Oct '12

I'm using boost to shuffle an array, but it's not looking as random as I would expect. Am I not using it right? The code below outputs sequences that look random mostly, but I see patterns such as 7 7 12 12 11. boost::random::mt19937 rng; boost::minstd_rand lcggen; lcggen.seed(clockTime); rng.seed(lcggen); unsigned min=1; unsigned max=15; for(unsigned i=0;i<5;i++) { boost::random::uniform_int_distribution<> dist(min,max); const int j = dist(rng); ... code that shuffles stuff using j ... min++; cout<<j<<' '; } Suggestions? Thanks! Robin -- www.cinepaint.org

[unique_ptr] How should I assign unique_ptr returned from a factory function, possibly using boost::move, in C++03
by Adam Romanek 26 Oct '12

26 Oct '12

Hi, the question is: how should I assign boost::interprocess::unique_ptr returned from a factory function, possibly using boost::move, in C++03? Here's an example: --- #include <boost/interprocess/smart_ptr/unique_ptr.hpp> using namespace boost::interprocess; class my_class { public: my_class() {} }; struct my_class_deleter { void operator()(my_class *p) {} }; typedef unique_ptr<my_class, my_class_deleter> uptr; uptr create() { return uptr(); } int main() { uptr x; x = create(); // return 0; } --- The problem is that gcc fails to compile the above code saying: main.cpp:22: error: ambiguous overload for ‘operator=’ in ‘x = create()()’ ../../boost_latest/boost/interprocess/smart_ptr/unique_ptr.hpp:211: note: candidates are: boost::interprocess::unique_ptr<T, D>& boost::interprocess::unique_ptr<T, D>::operator=(boost::rv<boost::interprocess::unique_ptr<T, D> >&) [with T = my_class, D = my_class_deleter] ../../boost_latest/boost/interprocess/smart_ptr/unique_ptr.hpp:249: note: boost::interprocess::unique_ptr<T, D>& boost::interprocess::unique_ptr<T, D>::operator=(int boost::interprocess::unique_ptr<T, D>::nat::*) [with T = my_class, D = my_class_deleter] I use gcc v4.4.3 and Boost v1.51.0.

How can I make the libboost_regex.a static library?
by Scott Johnson 26 Oct '12

26 Oct '12

Transitioning an application from CentOS 5 to CentOS 6 and I noticed that neither the boost-devel nor boost-static rpms contain the libboost_regex.a static library. The boost-static rpm has most of the static libs but not that one. The CentOS 5 boost-devel package had the static library. I know dynamic libraries are encouraged but I still need the static lib. I grabbed the boost src rpm. I guess I need to build a custom version of the static rpm, but not sure yet which Makefile or where to make a change to get the libboost_regex.a. Thanks for any help.
