c++ - 使用 clang++ 3.1 构建 Boost 1.50.0

Question

我正在尝试使用 clang++ 3.1 构建 Boost 1.50.0。我已经尝试使用默认的 darwin 工具集安装 Boost.Build，但我遇到了编译器错误。

有没有特定的方法来做到这一点？

graeme graeme-pc 13:35:14 /usr/local/boost_1_50_0
$ sudo /usr/local/bin/b2 toolset=clang cxxflags="-std=c++11 -stdlib=libc++" linkflags="-stdlib=libc++"

Building the Boost C++ Libraries.

看起来是打开 C++11 的 clang++ 和 Boost 1.50 的已知构建问题

• https://svn.boost.org/trac/boost/ticket/4999
• https://svn.boost.org/trac/boost/ticket/5774

您可以通过不构建信号来解决这个问题。以下步骤对我有用:

$ cd /usr/local/boost_1_50_0
$ sudo ./bootstrap.sh --with-toolset=clang
$ sudo ./b2 toolset=clang cxxflags="-std=c++11 -stdlib=libc++" linkflags="-stdlib=libc++" --without-signals
