newbie: boost_1_35_0 with stlport-5.1.5 under mingw
by Manuel Oswald 26 May '08

26 May '08

hi all, I'm an absolutly newbie and am struggling with building boost under mingw with stlport. My configuration: Windows XP service pack 2 mingw (current versions of all needed parts) msys as command prompt stlport 5.1.5 boost 1_35_0 building stlport works fine, unit tests are all compiled and all test are ok. Building a small test project (using std::strings, fstreams and wchar_t) also works fine. When building boost without stlport, all libs are build except the serialization-lib where the reasons seems to be that gcc3.4.5 doesn't support wchar_t type. building boost with stlport only produces some of the libs. how i build stlport: - i unpacked stlport to "d:/se/libs/stlport-5.1.5" and changed to folder "./build/lib" - configure - mingw32-make -fgcc.mak clobber depend install (i only want to use dynamic libs) how i build boost with stlport: in file boost_1_35_0/tools/build/v2/user-config.jam i added: using stlport : 5.1.5 : d:/se/libs/stlport-5.1.5/stlport d:/se/libs/stlport-5.1.5/lib ; then i run the configure-skript, which gives the following erros (in a messagebox, may not be the correct error, as i had to translate it from german): rxvt00000cbc the NTVDM-CPU has detected an illegal command CS:0fe5 IP:20e3 OP:63 68 74 20 7a where i press the ingnore-button (googling didn't give me an explanation) then i run bjam like that: bjam -a -d2 --toolset=gcc stdlib=stlport stage some libs can't be build because of their dependencies on other boost libs, e.g. wave-lib can't be build because thread-lib can't be build most can't be build due to the following errors (which I don't get when building without stlport): gcc.compile.c++ in.v2\libs\serialization\build\gcc-mingw-3.4.5\release\stdlib-stlport-5.1.5\threading-multi\xml_grammar.o "g++" -ftemplate-depth-128 -O3

serialization and NDEBUG
by Jeff 26 May '08

26 May '08

Hello everyone, I've written some code with the serialization library, using a binary archive and some derived classes. If I compile with -DNDEBUG then the code does stops working. If I remove just this one switch then everything works fine. Using -O0 or -O3 does not matter. This exists in 1_34_1 and 1_35_0. I am using linux with gcc 4.1.2. Any suggestions? Thanks, Jeff

Boost.MPI Problems
by Ransom Briggs 26 May '08

26 May '08

Hello, Here are the problems that I've had trying to get Boost.MPI and MPICH2 to work together (I've had these problems with both boost_1_35_0 and the CVS Boost versions) rbriggs@localhost ~/Desktop/boost_1_35_0 $ ./tools/jam/src/bin.linuxx86_64/bjam --with-mpi --user-config=user-config.jam error: Unable to find file or target named error: '/boost/python//boost_python' error: referred from project at error: 'libs/mpi/build' rbriggs@localhost ~/Desktop/boost_1_35_0 $ I took out the python library build (since I don't need the python libs) but still had problems after that. gcc.link.dll bin.v2/libs/mpi/build/gcc-4.1.2/release/threading-multi/libboost_mpi-gcc41-mt-1_35.so.1.35.0 /usr/lib/gcc/x86_64-pc-linux-gnu/4.1.2/../../../../x86_64-pc-linux-gnu/bin/ld: /opt/mpich/lib/libmpich.a(attr_get.o): relocation R_X86_64_32 against `a local symbol' can not be used when making a shared object; recompile with -fPIC /opt/mpich/lib/libmpich.a: could not read symbols: Bad value collect2: ld returned 1 exit status I'm unsure of where to fix this at, where should I add this? Thanks, Ransom

Static linking issues with custom library names
by Darren Mason 26 May '08

26 May '08

Hi all. I've built a static library that references boost threads, conditions and ptime. All the libraries were build with the following command "bjam --layout=system link=static release debug", then renamed to something more generic eg. boost_thread-mt.lib for the multi-threaded release version of the thread library. Now I know I did get the static libraries and not the DLL bridges because it was originally named libboost_thread-mt.lib. Actually I also used the --buildid command to add something other than -1_35, but I don't think that really matters. Anyway, the Win32 version of my project is built using VS2008, so I have a top level include file that defines BOOST_ALL_NO_LIB to prevent auto-linking. I then explicitly link the libraries that I need and build my project library. I assume it's actually linking everything in successfully since the output lib is vastly larger when I link the libs than when I don't. Now the real problem comes when I try to link to this library in my test application. I've switched up whether it is the lib or the application that defines BOOST_ALL_NO_LIB, and who actually links to the libraries etc. I've also made sure that they're all using the same run-time build settings eg. /MTd for both my lib and app, which would link to the -mt-gd version of the boost libraries. No matter what I do, I get a bunch of warnings about using locally defined symbols (changing which one links the libraries just changes whether the warning originates from my lib or boost's) and a few unresolved externals. They look something like this: Common.lib(thread.obj) : warning LNK4217: locally defined symbol ??0id@locale@std@@QAE@I@Z (public: __thiscall std::locale::id::id(unsigned int)) imported in function "void __cdecl `dynamic initializer for 'public: static class std::locale::id boost::date_time::date_facet<class boost::gregorian::date,char,class std::ostreambuf_iterator<char,struct std::char_traits<char> > >::id''(void)" (??__E?id@?$date_facet@Vdate @gregorian@boost@@DV?$ostreambuf_iterator@DU?$char_traits@D@std@@@std@ @@date_time@boost@@2V0locale@std@@A@@YAXXZ) Common.lib(thread.obj) : error LNK2019: unresolved external symbol __imp___beginthreadex referenced in function "private: void __thiscall boost::thread::start_thread(void)" (?start_thread@thread@boost@@AAEXXZ) If I'm not mistaken, LNK4217 means that the linker believes the symbol is local, but it's using a different calling convention, almost like it thinks it's importing from a DLL. I could suppress those by compiling against the Common Language Runtime, but somehow I think that I'm seeing these might be the root of my problem. Any thoughts? All I really want to be able to do is have an external app link to my libraries without having to also link to boost. I can only assume that I'm either not linking them into my library properly or that I'm not using the right boost defines. It's probably something really simple that I'm missing, but it's been driving me crazy and I'm just not getting anywhere. Any help would be appreciated. Thanks in advance, Darren Mason

mpl: remove types from set
by Alfred Kohl 25 May '08

25 May '08

Hi! I'd like to use MPL to remove elements of a set from another set. E.g.: using boost::mpl::set; struct a {}; struct b {}; struct c {}; typedef set<a, b, c> input; typedef set<b, c> remove_these; typedef boost::mpl::remove<input, remove_these>::type result; And result should be equal(?) to set<a>. Any idea how to do this? I'm a newbie on MPL terrain and it is quite brain-twisting... (I could use a beer to relief some strain) TIA Alfred -- Desperate Housewives - das Spiel!

[thread_safe_signals] thread safety and more
by Igor R. 25 May '08

25 May '08

Hello, I'd like to use thread_safe_signals, and I'm wondering if there're any examples that highlight use-cases where the thread-safety is utilized? For instance, is it safe to connect() from a thread, while the signal is "signaling" in another thread? Is it safe to signal from a thread while another thread might destroy the signal? Another question: what would be the most simple way to do asynchronous signaling? Probably, there already exists something in boost (even not officially released) that provides such a functionality? I mean something like this: at the stage of connecting to a signal I'd like to supply an asynchronous queue along with slot handler, and at the stage of signaling the signal - instead of direct execution of a functor - must just post it to the associated queue (slots' return values are not of interest to me). Thanks, Igor'. _________________________________________________________________ Connect to the next generation of MSN Messenger http://imagine-msn.com/messenger/launch80/default.aspx?locale=en-us&source=…

Igor, Thanks a lot. I figured they must be a way to do it; that work class slipped by me unnoticed on the reference page. It seems like they thought of everything. thanks > My question is how do I keep the thread's io_service.run() from returning right away, since there will be no work for the io_service.run() to do until the server lines up a new connection for the thread to handle?

problems compiling boost against visual studio 2008
by David _ 24 May '08

24 May '08

first of all, hi to everyone, i´m new to boost and this is my first post i´m running windows vista x64 and visual studio 2008 i´ve followed the instructions from the "getting started" section but no good results here this is what i´ve done 1- download boost build and compile bjam 3.1.16 2- download boost 1.35 source 3- place the bjam executable in the boost1.35 main folder 4- execute bjam with these parameters first try with bjam --prefix=c:\boost --toolset=msvc install all done in the visual studio shell the compilation starts and it builds a lot of libraries and files. When i try to make my first Boost program the visual studio tells me that there is a lib missing (libboost_thread-vc90-mt-s-1_35.lib) why didn´t the VS compile this??? PS: any idea where to find links to precompiled 1.35 MSVS2005 and MSVS2008 packages???? _________________________________________________________________ MSN Video. http://video.msn.com/?mkt=es-es

Questions about using program_options
by Chris Ross 24 May '08

24 May '08

I have a project that's currently doing manual command-line parsing, then using a suite of classes I developed to read from multiple formats of configuration files. In looking at boost libraries, I see that boost::program_options might be something worth using. The first question I have is "what config file formats does it use/ want" ? I'm still reading all of the docs, so this may become clear, but. The next question is, since this is one of the non-header-only libraries, how hard would it be to pull segments out of the boost distribution to ship with my suite of programs and build it along- side? Just to get the program_options component. (Though, as a side note, I'm also using Loki::SharedPtr in my project, so if that could be converted to boost::shared_ptr it might be less complicated. Then again, I'm using some of the more complicated features of SharedPtr, so it's not clear to me that boost::shared_ptr is adequate, which is why I didn't choose it in the first place.) Thanks... Any advice on taking portions of the boost code and bundling it into another source package would be appreciated. - Chris
