Also thanks, I was wondering how to do exactly the same thing the other day.

Using bind to call a member function
by Rob Caldecott 14 Mar '06

14 Mar '06

Greetings, Is it possible to use boost::bind in a for_each loop to call a member of the class that is making the call? For example: class CTest { public: void SomeFunc(const std::wstring& str) const { // Do something with str } void DoSomething() const { std::vector<std::wstring> v; v.push_back(L"test"); ... for_each(v.begin(), v.end(), bind(&CTest::SomeFunc, _1)); } }; Obviously the above will not compile - and I'm pretty sure that somewhere in the bind, "this" will need to be passed, but I am struggling to make this work. I know I could use a static member function or use a function object and pass it "this", but I wondered if there is a way to cut out the middle-man and call a member function directly in this way?

[serialization] Problem writing and reading in same block, with work-around
by Robert S. Grimes 14 Mar '06

14 Mar '06

Hi all, It seems there is a problem with using both an output and an input archive in the same code block. Here is a simple sample that illustrates the problem. By defining the symbol BREAK_IT, you can see the problem; not defining it, the example works. What is particularly odd is that it is throwing an std::bad_alloc from within text_iarchive_impl<Archive>::load(std::string &s) in text_iarchive_impl.ipp because the requested size is obviously wrong - for example, 3435973837!!! I can't follow well enough what is happening, but I have figured out a work-around from noticing the differences between my example and demo.cpp; in the latter, the writing and reading of an archive are performed in two separate functions, or more precisely, two different blocks. Is this normal? Have I missed the documentation about this? Still, seems rather fussy, though to be honest, I'm not likely to suffer from the workaround in "production" code, but it's a bit unnerving nonetheless... Thanks! -Bob Example follows: #include <fstream> #include <iostream> #include <string> #include <boost/archive/text_iarchive.hpp> #include <boost/archive/text_oarchive.hpp> class Simple { private: int anIntMember; bool aBoolMember; template<class Archive> void serialize(Archive & ar, const unsigned int file_version) { ar & BOOST_SERIALIZATION_NVP(anIntMember) & BOOST_SERIALIZATION_NVP(aBoolMember); } // Grant access to serialization library friend class boost::serialization::access; public: Simple(): anIntMember(27), aBoolMember(false) {} int GetAnIntMember() const { return anIntMember; } void SetAnIntMember(int v) { anIntMember = v; } bool GetABoolMember() const { return aBoolMember; } void SetABoolMember(bool v) { aBoolMember = v; } }; #define BREAK_IT void TestBoostText(const Simple& parms) { #ifndef BREAK_IT { #endif // Write out to boost archive std::ofstream ofs("./boost.txt"); boost::archive::text_oarchive oa(ofs); oa << parms; /// Could use a better XML element name #ifndef BREAK_IT } #endif // Read it back and check Simple rparms; std::ifstream ifs("./boost.txt"); // THIS IS THE BROKEN LINE boost::archive::text_iarchive ia(ifs); ia >> rparms; std::cout << "Checking boost read..."; if (rparms.GetAnIntMember() == 99) { std::cout << "Worked!!!" << std::endl; } else { std::cout << "Failed - appears not to have been updated" << std::endl; } } int main(int argc, char* argv[]) { Simple parms; // Modify parms for testing purposes parms.SetAnIntMember(99); // Test both binary archives TestBoostText(parms); return 0; }

Known issues loading lots of objects with xml_iarchive?
by Christopher Gillett 14 Mar '06

14 Mar '06

I am serializing a LOT of objects, one per file. I can create XML for many thousands of objects with no issue. However, when trying to load a few hundred objects (using a separate program, btw) I am hitting a boost::archive::archive_exception with a stream error while loading around the 161st file, which I believe based on stack traces is coming from within boost::archive::basic_xml_grammar<char>::parse_end_tag (). The approach I'm taking is fairly textbook, so I'm curious if there are known issues with loading a lot of files, etc. Any advice appreciate. Thanks, Chris Gillett

Re: [Boost-users] Boost Statechart: general questionss about whatthelibrary can do
by RIVASSEAU Jean Noel 13 Mar '06

13 Mar '06

Hi Andreas Hmmm, at first that sounds more like a BGL problem than one for the statechart library. What you describe above is easy to do with an appropriately designed state machine but I'm not sure it would be the right abstraction. For what real-world problem do you plan to use Statechart? Actually, after I sent the mail I thought some more and yes, I realised that this can be more of a graph problem (shortest path or such...) so it would be easy to with the BGL. But I'd like to do it with Boost Statechart since my real-world problem is at heart a state problem (statechart). What I am trying to do is: * I have an embedded software to *test*. I am trying to develop a framework for somewhat automatically testing the software. If I look at the specification of the software, I have lots of possible states (specs mention a lot of UML like diagrams). I need to test if the software correctly respects the specification, that is, if it correctly changes from one state to another according to a given event. Since the diagrams are complex, and thus the state space is huge (sometimes more than 100 states), I'd like for my framework to be able to automatically go to a given state, to be able to test the software in that particular state. Eg, if you just start by powering up the device, I'd like to compute the paths (and thus, events, that have to be translated to commands sent to the embedded device) to go to a particular state. Do you think Boost Statechart would be a good abstraction? If yes, how can I implement some of the Boost algorithms for graphs (such as shortest path) to achieve what I need? Is it even possible from a technical point of view to convert a fsm to a graph and run BGL algorithms on it ? I am already quite familiar with the BGL as I used it extensively one year ago. Thanks. > When a transition is executed (automatically, or explicitely), can I > call a function? That is, when an event is processed, can I implement > some code that will be executed each time an event is processed ? Yes, that is probably the feature every FSM library supports. Ok.

[UTF] expected constructor, destructor, or type conversion before ‘(’ token
by Mateusz Łoskot 13 Mar '06

13 Mar '06

Hi, Today, I tried to build Unit Test examples on my Linux box and without success so far. I use Ubuntu Breezy, so installed Boost from packages. It seems to be Boost 1.33 version: http://packages.ubuntu.com/breezy/libs/libboost-test1.33.0 GCC on my box is: mloskot@dog:~$ g++ --version g++ (GCC) 4.0.2 20050808 (prerelease) (Ubuntu 4.0.1-4ubuntu9) Next, I checkouted Boost sources from CVS to have latest examples on my disk. As a first test I tried to build boost/libs/test/example/unit_test_example_04.cpp that mainly presents usage of BOOST_AUTO_TEST_SUITE and BOOST_AUTO_TEST_CASE macros. Here is error message I got: mloskot@dog:~/dev/boost/_cvs/boost/libs/test/example$ g++ -Wall unit_test_example_04.cpp -lboost_unit_test_framework unit_test_example_04.cpp:15: error: expected constructor, destructor, or type conversion before ‘(’ token unit_test_example_04.cpp:17: error: expected constructor, destructor, or type conversion before ‘(’ token unit_test_example_04.cpp:25: error: expected constructor, destructor, or type conversion before ‘(’ token unit_test_example_04.cpp:34: error: expected constructor, destructor, or type conversion before ‘;’ token unit_test_example_04.cpp:39: error: expected constructor, destructor, or type conversion before ‘(’ token unit_test_example_04.cpp:48: error: expected constructor, destructor, or type conversion before ‘(’ token unit_test_example_04.cpp:51: error: expected constructor, destructor, or type conversion before ‘(’ token unit_test_example_04.cpp:58: error: expected constructor, destructor, or type conversion before ‘;’ token mloskot@dog:~/dev/boost/_cvs/boost/libs/test/example$ Nothing more. I also tried to compile example as simple as possible example: #include <boost/test/unit_test.hpp> BOOST_AUTO_TEST_CASE( test1 ) { // with or without some check //BOOST_CHECK( true ); } but with the same results: mloskot@dog:~/dev/geos/_cvs/geos/tests/unit$ g++ -Wall -lboost_unit_test_framework envelope_class_test.cpp envelope_class_test.cpp:2: error: expected constructor, destructor, or type conversion before ‘(’ token I really don't have any idea what's going wrong. I tried to find some help in lists archives and the only similar problem I found is not very helpful: http://thread.gmane.org/gmane.comp.lib.boost.devel/115540 It's a bit old post and I use much newer Boost, 1.33, so it seems this post does not apply to my case. Could anyone explain me how to fix it? Honestly, I suppose that I should build Boost 1.34 from CVS but I'm not sure. I use 1.34 on Windows with VC++ 8.0 and compile my own test units and examples without problems. But I'd strongly prefer to use latest stable Boost in my project, just to not to force users to build Boost themself. Here I include (long) headers inclusion path generated by g++ -H: mloskot@dog:~/dev/boost/_cvs/boost/libs/test/example$ g++ -H -Wall unit_test_example_04.cpp -lboost_unit_test_framework .

Build a Universal Binary Boost library for Mac OSX
by Jwahar Bammi 13 Mar '06

13 Mar '06

Will appreciate a clear recipe to build Universal Binary boost libraries for Mac OSX (darwin). Boost is so wonderful, cant say the same for bjam ,,,,,,, Google'ing only pointed to the adobe patch I tried the adobe patch. Patched boost_1_33_1/tools/build/v2/tools/ darwin.jam then issued bjam -sarch=fat -sARCH=fat -sTOOLS=darwin stage (then install) did not make universal .dylibs. I suspect its got something to do with v1 vs v2 bjam or some such, i am just not grokking it. Will appreciate a ccokbook style recipe (have no particular desire to learn bjam) thanks bammi AT memento-inc DOT com

lambda and typeof, finally an effective in-place arithmetic metafunction generator.
by pongba 13 Mar '06

13 Mar '06

Okay, just image some sort of code like this: typedef mpl::vector_c<int,1,2,3> v; typedef mpl::accumulate<v,int_<0>,MPL_METAFUNC(_1*CONS(10)+_2)>::type::value result_value; // =123 Imaginably, the implementation of MPL_METAFUNC would involve BOOST_TYPEOF to deduce the type of "_1*CONS(10)+_2" so as to construct a corresponding metafunction, that is, "mpl::plus<_2,mpl::times<_1,int_<10> > >" (CONS here is used to work around the embarrassment that 10 becomes sort of variable when passed directly to operator*, so we use CONS(10) which expands into something like "int_<10>()" which entirely preserve "10" at compile-time). Arguably this is feasible, but I lack the time to implement it fully. (although it would be pretty simple, e.g. #define DEFINE_BINARY_OP(op,mpl_binray_op) \ template <typename T, typename U> \ mpl_binary_op<T,U> operator op (T t, U u) \ { \ return mpl_binary_op<T,U>(); \ } \ DEFINE_OP(+,mpl::plus) DEFINE_OP(-,mpl::minus) DEFINE_OP(*,mpl::times) DEFINE_OP(/,mpl::divide) ... Admittedly, there exists a name confliction between mpl::_1 and lambda::_1 due to the inherent difference between type and variable in the language, so we couldn't use the same _1 and _2 in both "plus<_1,_2>" and "_1+_2". Any good remedies for that?(of course we could always turn to "_1()+_2()" in which _1/2 means mpl::_1/2) My question is: Is this valuable?(IMO,it'll make arithmetic operation in metaprogramming much easier and clearer, just watch "_1*10+_2" v.s. "mpl::plus<_2,mpl::times<_1,int_<10> > >" you'll see that). And if it is, would Dave consider adding it to MPL? Thanks in advance! -- Regards!
