小编use*_*504的帖子

目标:我想使用Xcode 4.6在Matlab mex文件(R2013a)中使用C++ 11的线程STL

我修改了〜/ .matlab/R2013a/mexopts.sh

        CC='clang++'   # was llvm-gcc-4.2
        CXX='clang++'   # was llvm-g++-4.2
        MACOSX_DEPLOYMENT_TARGET='10.8'   # was 10.5. C++11 is supported >=10.7
        CXXFLAGS="$CXXFLAGS -std=gnu++11 -stdlib=libc++"   # additional flags

没有C++ 11功能的普通mex文件编译得很好.此外,编译器很好地检测到STL,但链接失败除外.
