与链接的boost :: program_options烦恼OSX上使用LLVM [英] Linking troubles with boost::program_options on OSX using LLVM

问题描述

我无法通过我的C ++程序的链接阶段获得由于与升压1.49的问题。我已经切换到C ++（-std = C ++ 11 -libc =的libc ++）这对于另一块code的正常工作（也使用升压）。使用带有自制安装升压：

I'm having trouble getting through the linking phase in my C++ program due to problems with Boost 1.49. I have switched to c++ (-std=c++11 -libc=libc++) which works fine for another piece of code (which also uses boost). Boost was installed using homebrew with:

brew install boost --universal --with-mpi --with-icu

麻烦始于的boost :: program_options。我得到的链接错误是这样的：

The trouble starts with boost::program_options. I get the link errors like this:

  "boost::program_options::validate(boost::any&, std::__1::vector<std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> >, std::__1::allocator<std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> > > > const&, std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> >*, int)", referenced from:

... etc. ...

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

这是一个有些奇怪，因为所使用的库做一个纳米透露，该符号出现在那里：

This is a little strange, because doing an nm on the library used reveals, that the symbol appears to be there:

nm -U /usr/local/lib/libboost_program_options-mt.dylib  | grep validate
0000000000019880 - 01 0000   FUN __ZN5boost15program_options8validateERNS_3anyERKSt6vectorISbIwSt11char_traitsIwESaIwEESaIS7_EEPSsi

0000000000019c70 T __ZN5boost15program_options8validateERNS_3anyERKSt6vectorISsSaISsEEPbi

我已经尝试自制哄通过设置CXX和CXX_FLAGS因此在安装前编译铿锵而不是gcc提升。不知道我成功了，但。

I have already tried coaxing homebrew to compile boost with clang instead of gcc by setting CXX and CXX_FLAGS accordingly prior to installation. Not sure I succeeded though.

指针大大AP preciated。

Pointers greatly appreciated.

推荐答案

您将需要重新编译铿锵和STD11标志提振，libc中++库之前不是二进制与OSX（GCC很早的版本已安装的libstdc ++兼容更改为GPL3）。如果您铿锵的版本是3.1或以上，那么你可以使用（否则改变C ++ 11的C ++ 0x的早期版本）。

You will need to recompile boost with clang and std11 flags, the libc++ library is not binary compatible with the installed libstdc++ in OSX (very early version of gcc prior to changing to gpl3). If your version of clang is 3.1 or over then you can use (otherwise change c++11 to c++0x for earlier versions).

./bootstrap.sh
mkdir build
sudo ./bjam toolset=clang cxxflags="-std=c++0x -stdlib=libc++" variant=release link=static threading=multi runtime-link=shared --build-dir=Build --layout=system --without-mpi --without-python install --prefix=/usr/local 

您当然可以改变任何这些如你所愿，除了

You can of course alter any of these as you wish except

工具=铛CXXFLAGS = - STD =的C ++ 0x -stdlib = libc的+ +

toolset=clang cxxflags="-std=c++0x -stdlib=libc++"

这应该为你工作。
