如何在Python setup.py脚本中将标志传递给gcc? [英] How to pass flag to gcc in Python setup.py script?

问题描述

我正在用C编写一个Python扩展，它需要CoreFoundation框架(除其他外).可以使用以下命令进行编译:

I'm writing a Python extension in C that requires the CoreFoundation framework (among other things). This compiles fine with:

gcc -o foo foo.c -framework CoreFoundation -framework Python

(-framework"是Apple专用的gcc扩展，但这没关系，因为无论如何我都在使用它们的特定框架)

("-framework" is an Apple-only gcc extension, but that's okay because I'm using their specific framework anyway)

我如何告诉setup.py将此标志传递给gcc?

How do I tell setup.py to pass this flag to gcc?

我尝试了这个，但是它似乎不起作用(它可以编译，但是当我尝试运行它时会抱怨未定义的符号):

I tried this, but it doesn't seem to work (it compiles, but then complains of undefined symbols when I try to run it):

from distutils.core import setup, Extension
setup(name='foo',
      version='1.0',
      author='Me',
      ext_modules=[Extension('foo',
                             ['foo.c'],
                             extra_compile_args=['-framework CoreFoundation'])])

这似乎起作用:

from distutils.core import setup, Extension
setup(name='foo',
      version='1.0',
      author='Me',
      ext_modules=[Extension('foo',
                             ['foo.c'],
                             extra_link_args=['-framework', 'CoreFoundation'])])

推荐答案

也许您也需要设置extra_link_args?编译源代码时使用extra_compile_args，链接结果时使用extra_link_args.

Maybe you need to set extra_link_args, too? extra_compile_args is used when compiling the source code, extra_link_args when linking the result.
