Where is the Wave Driver in Boost 1.86?
by Stirling Westrup 20 Aug '18

20 Aug '18

I recently tried to recompile an old version of the Wave Driver using the latest version of Boost::Wave and there were many cryptic warnings and errors. So, I figured I'd just upgrade to the latest copy of the source, only I cannot find it in the latest Boost::Wave, despite the documentation still referring to it. Nor does there appear to be an already-compiled tool supplied with the distro versions of Boost. (Something which has always been claimed by the docs, but has never been true in my experience -- which is why I was forced to originally compile it from source.) -- Stirling Westrup Programmer, Entrepreneur. https://www.linkedin.com/e/fpf/77228 http://www.linkedin.com/in/swestrup http://technaut.livejournal.com http://sourceforge.net/users/stirlingwestrup

Why I had to use-D_GLIBCXX_USE_CXX11_ABI=0 to get a Boost.Test unit test to build and run
by Arved Sandstrom 20 Aug '18

20 Aug '18

This is in the nature of a question, I am wondering *why* I had to use the -D_GLIBCXX_USE_CXX11_ABI=0 setting. This development is happening on Centos 7, where the system gcc/g++ is 4.8.5. So I recently built and installed gcc/g++ 8.2.0 from source, because I like Linux and prefer to try out C++17 stuff there rather than using a recent Visual Studio. That's just background. In any case I built the Boost Test module with ./b2 cxxflags="-stdlib=libc++ -std=c++14" linkflags="-stdlib=libc++ -std=c++14" going off suggestions I found. No evident problems there. After the install, among other things I end up with /usr/local/lib/libboost_unit_test_framework.so Now, I attempted to build a unit test with g++ -std=c++14 DocumentTest.cpp ../src/Document.cpp -I../include -L/usr/local/include -DBOOST_TEST_DYN_LINK -lboost_unit_test_framework The linker complained about an undefined reference for boost::unit_test::ut_detail::normalize_test_case_name[abi:cxx11](boost::unit_test::basic_cstring<char const>) Using nm -D on the shared library I see that the proper export symbol is there. abi:cxx11 seemed to offer some indication as to the problem, which is why after some experimentation I found that adding -D_GLIBCXX_USE_CXX11_ABI=0 to the unit test build command did the trick. The resulting a.out executes just fine (purely for debugging I made sure the unit test had a C++14 feature). I thought I sort of understood the ABI change business, gcc 5.1 before and after, but I guess I don't. What do I need to do, perhaps at the stage of building a Boost shared library, to not have to use that flag? Thanks for any wisdom. Arved Sandstrom

Specifying Compiler when invoking bootstrap.sh
by Michalke, Simon 20 Aug '18

20 Aug '18

Hello all, simple question: How do I specify the compiler that will be used to compile boost directly? I would like to provide the whole path. I have a big CMakeProject that depends on Boost. And boost should be preferably build with the same Compiler. Regards, Simon

[boost.locale] linguistic case discrimination in translation
by Olaf Peter 19 Aug '18

19 Aug '18

Hello Users, I like to join two translation into a single one using the word 'and' if the code path require it, e.g. translation 1 is: "{1} error" and translation 2 is: "{1} warning" if the relevant err/warn counter are both != 0 I want to combine this statement using the mentioned 'and'. I guess, an example teels more than this here: see https://wandbox.org/permlink/HbnCLQKhHAb3eqZr or even on bottom. Line 89 ... 94 looks too complicated to me even for the translator which need an own context of the intend. I've seen a lot of dating formating flags, but nothings useful for my use case. BTW; does boost.locate still using auto_ptr? I had to add the option '-Wno-deprecated' to rid the warnings... Thanks, Olaf -----------------------8<-------------------------- #include <iostream> #include <boost/locale.hpp> struct context { std::size_t error_count; std::size_t warning_count; context() : error_count{ 0 } , warning_count{ 0 } { } }; struct failure_status { context const& ctx; failure_status(context const& ctx_) : ctx{ ctx_ } { } std::ostream& operator()(std::ostream& os) const; }; static inline std::ostream& operator<<(std::ostream& os, failure_status const& status) { return status(os); } namespace detail { struct error_message { std::size_t const count; explicit error_message(std::size_t count_) : count{ count_ } { } std::ostream& operator()(std::ostream& os) const { using boost::locale::format; using boost::locale::translate; if(count) { os << format(translate( "{1} error", "{1} errors", count)) % count ; } return os; } }; std::ostream& operator<<(std::ostream& os, error_message const& err_msg) { return err_msg(os); } struct warning_message { std::size_t const count; explicit warning_message(std::size_t count_) : count{ count_ } { } std::ostream& operator()(std::ostream& os) const { using boost::locale::format; using boost::locale::translate; if(count) { os << format(translate( "{1} warning", "{1} warnings", count)) % count ; } return os; } }; std::ostream& operator<<(std::ostream& os, warning_message const& warn_msg) { return warn_msg(os); } } // namespace detail std::ostream& failure_status::operator()(std::ostream& os) const { using detail::warning_message; using detail::error_message; using boost::locale::translate; bool const any_failure = [&] { return ctx.error_count || ctx.warning_count; }(); if(any_failure) { os << error_message(ctx.error_count); if(ctx.warning_count) { os << translate(" and "); // poor translator ... } os << warning_message(ctx.warning_count); os << translate(" generated."); } return os; } int main() { context ctx; ctx.error_count = 1; ctx.warning_count = 42; std::cout << failure_status(ctx) << "\n"; } ----------------------->8--------------------------

[release][build] Errors compiling 1.68.0 with VS2015 after VS2017
by Gavin Lambert 10 Aug '18

10 Aug '18

I first used the following to compile Boost 1.68.0 for VS2017: cd boost_1_68_0 bootstrap b2 -j8 --build-dir=build toolset=msvc-14.1 variant=debug,release link=shared threading=multi runtime-link=shared address-model=32,64 stage This appears to have built successfully, although I didn't review the logs. Afterwards, I tried to build it also for VS2015: b2 -j8 --build-dir=build15 toolset=msvc-14.0 variant=debug,release link=shared threading=multi runtime-link=shared address-model=32,64 stage This build output is full of these errors, however (not specific to Boost.Math, this is just one I happened to capture): Creating library build15\boost\bin.v2\libs\math\build\msvc-14.0\debug\threading-multi\boost_math_c99l-vc140-mt-gd-x32-1_68.lib and object build15\boost\bin.v2\libs\math\build\msvc-14.0\debug\threading-multi\boost_math_c99l-vc140-mt-gd-x32-1_68.exp msvc.manifest.dll build15\boost\bin.v2\libs\math\build\msvc-14.0\debug\threading-multi\boost_math_c99l-vc140-mt-gd-x32-1_68.dll 'mt' is not recognized as an internal or external command, operable program or batch file. if exist "build15\boost\bin.v2\libs\math\build\msvc-14.0\debug\threading-multi\boost_math_c99l-vc140-mt-gd-x32-1_68.dll.manifest" ( call "build15\boost\bin.v2\standalone\msvc\msvc-14.0\msvc-setup.bat" x86 >nul mt -nologo -manifest "build15\boost\bin.v2\libs\math\build\msvc-14.0\debug\threading-multi\boost_math_c99l-vc140-mt-gd-x32-1_68.dll.manifest" "-outputresource:build15\boost\bin.v2\libs\math\build\msvc-14.0\debug\threading-multi\boost_math_c99l-vc140-mt-gd-x32-1_68.dll;2" ) ...failed msvc.manifest.dll build15\boost\bin.v2\libs\math\build\msvc-14.0\debug\threading-multi\boost_math_c99l-vc140-mt-gd-x32-1_68.dll build15\boost\bin.v2\libs\math\build\msvc-14.0\debug\threading-multi\boost_math_c99l-vc140-mt-gd-x32-1_68.lib build15\boost\bin.v2\libs\math\build\msvc-14.0\debug\threading-multi\boost_math_c99l-vc140-mt-gd-x32-1_68.pdb... Am I missing some incantation? Oddly when I run a VS2015 Developer Command Prompt it also doesn't know where to find mt.exe. A VS2017 Developer Command Prompt finds it at C:\Program Files (x86)\Windows Kits\10\bin\10.0.17134.0\x86\mt.exe. (I'm not having any apparent problems compiling projects within VS2015, but possibly I haven't given it a thorough workout since recently upgrading VS2017.) On another machine (which only has VS2015 installed), the VS2015 Developer Command Prompt finds it at C:\Program Files (x86)\Windows Kits\8.1\bin\x86\mt.exe. I do have that same path and file on my PC, but it's not being found for some reason? Adding it to my PATH before running b2 doesn't help; I assume it's overriding this. It looks like the VS2015 Developer Prompt is putting C:\Program Files (x86)\Windows Kits\10\bin\x86 into my PATH, which exists but doesn't contain any tools. I managed to "fix" the VS2015 Developer Prompt by commenting out the line in "C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\Tools\vcvarsqueryregistry.bat" that looks for the Windows 10 SDK. (Thereby allowing it to find the 8.1 SDK, which contains mt.exe.) After deleting the build15 directory and adding --reconfigure to the b2 incantation above, this seems to have allowed Boost to compile as well, but I find the whole thing a bit troubling. Is there a better way to resolve this?

Any plans to fix C++11 nullptr issues?
by James Walker 04 Aug '18

04 Aug '18

When Clang is compiling C++11 code, there may be a warning (-Wzero-as-null-pointer-constant) when 0 or NULL is used instead of nullptr. I've seen these warnings from Smart Ptr and Tokenizer in particular, but I suppose it's all over. This is still the case in 1.68.0 beta 1.
