Python distutils gcc路径 [英] Python distutils gcc path

问题描述

我正在尝试交叉编译pycrypto软件包，但是越来越近了，但是我遇到了一个我不知道的问题。

I'm trying to cross-compile the pycrypto package, and I'm getting closer and closer however, I've hit an issue I just can't figure out.

我希望distutils使用交叉编译专用的gcc-，因此我设置了CC env var，并且似乎尊重第一次编译器调用的设置，但是就是这样。

I want distutils to use the cross-compile specific gcc- so I set the CC env var and it seems to respect the setting for the first invocation of the compiler, but thats it.

export CC="/opt/teeos/buildroot/output/host/usr/bin/i586-linux-gcc"
/opt/teeos/buildroot/output/host/usr/bin/i586-linux-gcc -fno-strict-aliasing -fwrapv -Wall -Wstrict-prototypes -fPIC -std=c99 --sysroot=/opt/teeos/buildroot/output/staging -I/opt/teeos/buildroot/output/staging/usr/include/python2.7 -O3 -fomit-frame-pointer -Isrc/ -I/usr/include/python2.7 -c src/_fastmath.c -o build/temp.linux-i686-2.7/src/_fastmath.o
gcc -pthread -shared -Wl,-O1 -Wl,-Bsymbolic-functions -Wl,-Bsymbolic-functions build/temp.linux-i686-2.7/src/_fastmath.o -lgmp -o build/lib.linux-i686-2.7/Crypto/PublicKey/_fastmath.so
unable to execute gcc: No such file or directory

我暂时将系统gcc移到了无法找到的位置。

I temporarily moved my systems gcc so it can't be found.

如何使distutils在每次调用编译器时都尊重 CC = / opt / buildroot ... 选项/设置我要distutils使用的GCC / LD的路径？

How do I make distutils respect the CC=/opt/buildroot... option for every invocation of the compiler / set the path to the GCC / LD I want distutils to use?

推荐答案

这听起来与我最近为< a href = https://stackoverflow.com/questions/5967065/python-distutils-not-using-correct-version-of-gcc/5968410#5968410>自定义distutils编译器。您还需要定义 LDSHARED ，这是用于产生最终共享库的命令。看看是否可行：

This sounds similar to another answer I recently gave for customizing the distutils compiler. You'll also need to define LDSHARED which is the command used to produce the final shared object. See if this works:

>>> from distutils import sysconfig
>>> sysconfig.get_config_var('LDSHARED')
'gcc -pthread -shared -Wl,-O1 -Wl,-Bsymbolic-functions'
>>> sysconfig.get_config_var('CC')
'gcc -pthread'

然后替换 gcc ，并在 CC 和 LDSHARED 环境中使用所需的编译器和选项变量：

Then replace gcc with your desired compiler and options in the CC and LDSHARED environment variables:

% LDSHARED="i586-linux-gcc -pthread -shared -Wl,-O1 -Wl,-Bsymbolic-functions" \
  CC="i586-linux-gcc -pthread" python setup.py build
