“ Thread” Boost无法在OSX上构建？

Question

i'm trying to compile boost 1.57 from source on OSX 10.10.5 but seems to fail to build "thread" lib.

OSX 10.10.5 Yosemite

Xcode 6.1

here is compiling command "

$ ./b2 toolset=clang cxxflags="-arch x86_64 -std=c++11 -stdlib=libstdc++ -ftemplate-depth=512" linkflags="-stdlib=libstdc++" link=static install --with-program_options --with-system --with-filesystem --with-chrono --with-thread

Error :

What do you think is the problem ?

Answer 1

I am a latecomer to the party but I have ran into the same issue and the problem is that you want to build it with C++11 but not with libc++.

It looks like that the older version of C++11 implementations were patchy. The libstdc++ is missing the type_traits header, as simple as that. Use the -stdlib=libc++ switch and you should be sorted.
