Hey, I think you need to make sure that clang is running with the '-std=c++11' option, or that is added to your cxxflags somehow. I don't know if there is a better way now, but to build with clang/libc++/C++11 on OS X I add the following to tools/build/v2/user-config.jam: using clang : osx : xcrun clang -arch i386 -arch x86_64 -stdlib=libc++ -std=c++11 -fvisibility-inlines-hidden ; and then run: ./b2 toolset=clang-osx On Sat, May 11, 2013 at 6:51 AM, Roman Himmes <himmes@idev.de> wrote:
Hi,
at the moment I try to compile a project that is using boost on my mac. The project is using c++11 features so I need to use clang with libstdc++. I compiled boost with:
./b2 toolset=clang cxxflags="-stdlib=libc++" linkflags="-stdlib=libc++"
It seems that trying to include "boost/date_time/gregorian/gregorian.hpp" leads to the compile error below. Googling I found some remarks about char16_t and char32_t types new in C++-11. Is that compiler/library combination in boost not supported yet? Has anyone successfully got that combination to work?
Best Regards,
