Hello, Looking at the regression test results, it seems that some typeof tests do not compile on IBM. Did somebody have a look at this? Is this a known problem? Thanks, Karl

[iostreams] Problems using filtering_stream and code_converter
by Niklas Wiberg 11 Oct '05

11 Oct '05

Hi, I'm using boost 1.33.0 on windows (VC++6). I would like to use a code_converter to convert internal std::wstring's (which I understand are ucs2 in windows/vstudio, but that shouldn't matter here I guess) to utf-8 when saving to file. Here is the failing code: <code> void main() { typedef boost::iostreams::code_converter<boost::iostreams::file_sink, WideCharToUtf8Cvt> my_sink; std::wstring teststr(L"Blah blah."); boost::iostreams::filtering_wostream out; boost::iostreams::file_sink myFile("out.txt"); out.push(my_sink(myFile)); out << teststr; } </code> WideCharToUtf8Cvt is my own codecvt implementation. The problem is that I get a crash as the stream is being destroyed. The call stack is too deep to include here, but one of the last things are: policy_type& dev() { return **dev_; } in boost.iostreams.detail.code_converter_impl which calls boost::iostreams::detail::optional<boost::iostreams::detail::concept_adapter<boost::iostreams::basic_file_sink<char> > >::operator*() operator*() asserts on initialized_ which is false in this case. I've tried both with vc++6 sp5 and vc++ 7.1 with the same results. Also, there is no difference if I use this typedef for my_sink: typedef boost::iostreams::code_converter<boost::iostreams::file_sink> my_sink; so I don't think my codecvt implementation is to blame... The file out.txt actually gets filled with the expected data. Am I going about this the completely wrong way or am I just missing some important detail? Any help would be greatly appreciated, Niklas Wiberg

BOOST_STATIC_ASSERT
by Edward Grace 11 Oct '05

11 Oct '05

Dear All, I am encountering a problem with BOOST_STATIC_ASSERT, it is producing compile-time errors that are a little cryptic. When using BOOST_STATIC_ASSERT such as class rtm : public matrix<ElementType> { BOOST_STATIC_ASSERT(::boost::is_float<ElementType>::value || ejg::boost::is_complex<ElementType>::value); public: ... ... .. Instantiation of the rtm class with a non float or non complex type, such as: ejg::oned::rtm<char> M; causes the following compiler error. error: invalid application of sizeof to incomplete type boost::STATIC_ASSERTION_FAILURE<false> Boost 1.32.0 g++ 4.0.1 Obviously generating a compiler error is the correct behaviour, I want to make sure that only complex or float type objects are instantiated. The problem is that the compiler error is rather cryptic. >From the documentation of boost http://www.boost.org/doc/html/boost_staticassert.html, I should be seeing Illegal use of STATIC_ASSERTION_FAILURE<false> Is there any way this can be improved by generating the error or is it too much of a compiler issue? -ed

[Boost.Build] unable to cross-compile 1_33_0
by BRIDGES Dick 11 Oct '05

11 Oct '05

My apologies in advance if this question is only for the jamboost mailing list but I very much need to cross-compile boost_1_33_0 and I can't seem to make this version work. # bjam --v2 --version Boost.Build V2 (Milestone10) Boost.Jam 03.01.11 (I haven't received any responses on the jamboost mailing list so I assume I'm formulating my question incorrectly. If there is something wrong with the way I'm asing this question, would someone please point it out to me?) I am trying to compile a host (X86, linux) and a target (ARM9) version of the boost_1_33_0 libraries using the "standard" (Core3) gcc and a gcc-arm cross-compiler. Can someone point me to the documentation that is "authoritative" for 1_33_0 and describes how to configure [which files] and invoke bjam for multiple compilers on the same computer? I found (and read) *LOTS* of historical material describing how to configure and invoke bjam for v1 and v2 for prior versions. Vladimir Prus provided an answer (in the form of a user-config.jam mod) for 1_32_0 last April... <extract> I'd use this: using gcc : 3.4 ; using gcc : 3.4arm : /path/one/arm-g++ : <other stuff> ; using gcc : 3.4ppc : /path/two/ppc-g++ : <other stuff> ; and them bjam gcc-3.4 gcc-3.4arm gcc-3.4ppc </extract> ...which worked fine with 1_32.0, but I can't get it to work with the 1_33_0 version. No matter how I invoke bjam, it seems to interpret the compiler as the target. bjam gcc-3.4arm => "don't know how to make gcc-3.4arm" bjam --v2 gcc-3.4arm => "could not find main target gcc-3.4arm" bjam "-sTOOLS=gcc-3.4arm" => "gcc-3.4arm-tools-jam: No such file..." I've been reduced to "trying things." Any advice or suggestions would be greatly appreciated. Regards, "Desperate" Dick Bridges

Hi Has anyone tried using BOOST XML serialisation with C#? Is that feasible? Basically the scenario is a C# front end client talking to a C++ back end server via XML messages both sides using Boost XML Serialisation / Deserialisaion framework. Regards SP
