Error Handling issue in NonCopyable Interface
by John Pallino 08 Aug '14

08 Aug '14

Hello, I am having error handling issues that is in regards to the NonCopyable Interface library. Here is the source code: #include <boost/noncopyable.hpp> #include <iostream> class A : public boost::noncopyable { public: A() { std::cout << "In A \n" << std::endl; } class AnError {}; void Func() { if () //error condition throw AnError(); } }; int main() { try { A object1; A object2(object1); object1 = object2; } catch (A::AnError) { //tell user about error. } return 0; } } So far, I have tried on the forums in CPlusPlus.com and MSDN, but no responses. Since that Boost.org has created and authored the NonCopyable.hpp library, I would like to get some assistance. Can anybody give me some solutions on how to suppress any compilation errors? Thanks in advance. Email me back at the Cc: if you have any answers or comments with detailed information and examples. John P.

[1.56.0] Release Candidate 3 available
by Marshall Clow 07 Aug '14

07 Aug '14

We've created a third release candidate to fix a one more issue with Boost.Range. The files for 1.56.0 RC3 are available at: http://boost.cowic.de/rc/ As always, the release managers would appreciate it if you download the candidate of your choice and give building it a try. Please report both success and failure, and anything else that is noteworthy. The files (and associated md5s) are: MD5 (./boost_1_56_0_rc3.7z) = b7a72a6a6f487fa445333b4e115c6171 MD5 (./boost_1_56_0_rc3.tar.bz2) = a744cf167b05d72335f27c88115f211d MD5 (./boost_1_56_0_rc3.tar.gz) = 8c54705c424513fa2be0042696a3a162 MD5 (./boost_1_56_0_rc3.zip) = fc16da21d641e03715a4144cb093964e Thanks! -- The release managers

Clang, -pedantic, and variadic macro warnings
by Edward Diener 06 Aug '14

06 Aug '14

My test show that if you compile with clang, pass the '-pedantic' option, and also pass 'std=c++0x' or 'std=c++11', that the many warnings about variadic macro use do not show in the output. I know there was a discussion and an assertion that the warnings do show in the output oonce '-pedantic' is passed as a compiler option even though a 'std=xxx' is passed that covers variadic macros, but I am not seeing that in my tests. If anybody else can tell me of a Boost library build where clang is the compiler, 'pedantic' is passed, and the appropriate 'std=xxx' to cover variadic macro use is passed, and the clang compiler warnings about using variadic macros show up, it would be appreciated.

[python] Building and Testing needs to be updated for modular-boost
by Edward Diener 05 Aug '14

05 Aug '14

Attempting to follow the building and testing explanation for Boost.Python in modular-boost, it appears it no longer works with the new structure of modular-boost and Boost Build. Staring with the 3.1 Basic Procedure section I invoke in the libs/python/example/quickstart/ directory the command: > b2 toolset=gcc-4.8.1 --verbose-test test only to receive: > Unable to load Boost.Build: could not find build system. > --------------------------------------------------------- > C:\Programming\VersionControl\modular-boost\libs\python\example\quickstart\boost-build.jam attempted to load the build system by invoking > > 'boost-build ../../../../tools/build/v2 ;' > > but we were unable to find "bootstrap.jam" in the specified directory > or in BOOST_BUILD_PATH (searching C:\Programming\VersionControl\modular-boost\libs\python\example\quickstart\../../../../tools/build/v2). > > Please consult the documentation at 'http://www.boost.org'. I do not know who is taking care of Boost Python now but it appears that it needs to be updated for modular-boost.

Files in Github

Which subrepository do the files under /home/boost/boost belong to? More specifically, I made a change to /home/boost/boost/date_time/time_resolution_traits.hpp and I am looking to push it upstream, but I cannot find who this file belongs to. Sincerely, -Axel

[filesystem] develop broken after current merge
by Jürgen Hunold 05 Aug '14

05 Aug '14

Hi Beman, the last merge broke Boost.FileSystem on Linux using gcc(-4.8) and clang(-3.6) in c++11 mode. Diagnosic: include/boost/filesystem/path_traits.hpp contains #ifndef BOOST_NO_CXX11_CHAR16_T inline void convert(const char16* from, const char16* from_end, This should most probably be "char16_t" for C++11. The same for "char32" which should be "char32_t". This affects several other files. This one I could patch myself. But then I encountered: BOOST_ROOT/boost/filesystem/path_traits.hpp:131:13: error: ‘interop’ does not name a type typedef interop::conversion_iterator<interop::narrow, interop::utf16, const char16*> I can't find a definition of "interop" anywhere in the current repository... If you need more diagnostics, please ping me. Yours, Jürgen -- * Dipl.-Math. Jürgen Hunold ! * voice: ++49 4257 300 !
