Python setuptools 不包括 C++ 标准库 headers

Question

我正在尝试将 Python 包装程序编译为我编写的小型 C++ 库。我已经编写了以下 setup.py 脚本来尝试使用 setuptools 来编译包装器：

from setuptools import setup, Extension
import numpy as np
import os

atmcmodule = Extension(
    'atmc',
    include_dirs=[np.get_include(), '/usr/local/include'],
    libraries=['mcopt', 'c++'],  # my C++ library is at ./build/libmcopt.a
    library_dirs=[os.path.abspath('./build')],
    sources=['atmcmodule.cpp'],
    language='c++',
    extra_compile_args=['-std=c++11', '-v'],
    )

setup(name='tracking',
      version='0.1',
      description='Particle tracking and MC optimizer module',
      ext_modules=[atmcmodule],
      )

然而，当我运行 python setup.py build 在 OS X El Capitan 上时，clang 抱怨找不到一些 C++ 标准库 headers:

In file included from atmcmodule.cpp:7:
In file included from ./mcopt.h:11:
In file included from ./arma_include.h:4:
/usr/local/include/armadillo:54:12: fatal error: 'initializer_list' file not found
  #include <initializer_list>
           ^
1 error generated.
error: command 'gcc' failed with exit status 1

将 -v 标志传递给编译器表明它正在搜索以下包含路径：

#include <...> search starts here:
 /Users/[username]/miniconda3/include
 /Users/[username]/miniconda3/lib/python3.4/site-packages/numpy/core/include
 /usr/local/include
 /Users/[username]/miniconda3/include/python3.4m
 /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include/c++/4.2.1
 /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include/c++/4.2.1/backward
 /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../lib/clang/7.0.0/include
 /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include
 /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include
 /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/System/Library/Frameworks (framework directory)
End of search list.

这显然不包括 C++ 标准库的路径 headers。如果我用 -v 选项编译一个小的测试 C++ 源代码，我可以看到 clang++ 通常也会搜索路径 /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../include/c++/v1，如果我在 include_dirs 中包含这个路径我的 setup.py 脚本中 Extension 的选项，然后扩展模块可以正确编译并运行。但是，hard-coding 进入脚本的这条路径似乎不是一个好的解决方案，因为该模块还需要在 Linux.

上工作

所以，我的问题是 如何正确地使 setuptools 包含所需的 headers？

当 setuptools 尝试编译扩展时，它打印第一个命令运行ning:

gcc -fno-strict-aliasing -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -I/Users/[username]/miniconda3/include -arch x86_64 -I/Users/[username]/miniconda3/lib/python3.4/site-packages/numpy/core/include -I/Users/[username]/Documents/Code/ar40-aug15/monte_carlo/mcopt -I/usr/local/include -I/Users/[username]/miniconda3/include/python3.4m -c /Users/[username]/Documents/Code/ar40-aug15/monte_carlo/atmc/atmcmodule.cpp -o build/temp.macosx-10.5-x86_64-3.4/Users/[username]/Documents/Code/ar40-aug15/monte_carlo/atmc/atmcmodule.o -std=c++11 -fopenmp -v

如果我将此命令粘贴到终端并运行自己粘贴，扩展编译成功。所以我怀疑 setuptools 正在修改一些我不知道的环境变量，或者它对实际上是运行ning.

的命令撒了一些谎

Answer 1

Setuptools 尝试使用 same flags used to compile the Python interpreter. After checking the flags used to compile my Python install (from Anaconda), I found it was compiling for a minimum Mac OS X version of 10.5. This seems to make it use the GCC libstdc++ instead of clang's libc++ (which supports C++11) 编译 C/C++ 扩展模块。

这可以通过将环境变量 MACOSX_DEPLOYMENT_TARGET 设置为 10.9（或更高版本）或将 '-mmacosx-version-min=10.9' 添加到 extra_compile_args 来解决。
