Python.h header file missing on Mac OS X 10.6
提问by Brett Morris
I'm trying to access a shared C library in Python with ctypeson Mac OS X 10.6.8 with Python 2.7.4. To do this, I need to #include <Python.h>in my C code. If I try to compile a C script that only has that one include statement in it, call it "sample.c", I get:
我正在尝试ctypes使用 Python 2.7.4 在 Mac OS X 10.6.8 上访问 Python 中的共享 C 库。为此，我需要#include <Python.h>在我的 C 代码中。如果我尝试编译一个只有一个包含语句的 C 脚本，将其命名为“sample.c”，我得到：
$ gcc -shared -o sample.so sample.c
sample.c:1:20: error: Python.h: No such file or directory
Since I'm running Mac 10.6, I have Xcode 3.2.6, the latest version available on this iteration of OS X without paying to upgrade to 10.7 and getting Xcode 4. Is there a way to get the Python header file without upgrading my OS?
因为我运行的是 Mac 10.6，所以我有 Xcode 3.2.6，这是 OS X 的最新版本，无需支付升级到 10.7 和获得 Xcode 4 的费用。有没有办法在不升级我的操作系统的情况下获取 Python 头文件?

Python is a framework on Mac OS X so you need to,
Python 是 Mac OS X 上的一个框架，所以你需要，
#include <Python/Python.h>
You also need to call gccwith the -frameworkargument to actually do anything inside C,
您还需要gcc使用-framework参数调用以在 C 中实际执行任何操作，
gcc -shared -o sample.so sample.c -framework Python

I'm not sure about 10.6.8, but Python.hshould be in
我不确定 10.6.8，但Python.h应该在
/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7
if you installed the official python.org binary. Try adding
如果您安装了官方的 python.org 二进制文件。尝试添加
-I/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7
to your gcccommand and see if that works.
到你的gcc命令，看看是否有效。

In case you have installed Python using Brew, it may be worthwhile to check the location of where your headers are.
Try I/usr/local/Cellar/python/...
如果您已经使用 Brew 安装了 Python，那么检查头文件所在的位置可能是值得的。尝试I/usr/local/Cellar/python/...

Another way is to add `python-config --include`to the gcccall. It will expand to -I/usr/..., so
另一种方法是添加`python-config --include`到gcc呼叫中。它将扩展到-I/usr/...，所以
gcc -shared -o sample.so sample.c `python-config --include`
Also other options can be retrieved, such as `python-config --cflags --ldflags`.
还可以检索其他选项，例如`python-config --cflags --ldflags`.
