【问题描述】:
我正在尝试构建 python 包 pycrypto。 OS X 安装了 gcc-4.2 而不是 gcc-4.0,但 python 继续尝试使用 gcc-4.0。我怎样才能让它使用 gcc-4.2?或者我应该以不同的方式解决这个问题。
我收到以下错误:
bash-3.2$
bash-3.2$ sudo python setup.py build
running build
running build_py
running build_ext
warning: GMP library not found; Not building Crypto.PublicKey._fastmath.
building 'Crypto.Hash.MD2' extension
gcc-4.0 -fno-strict-aliasing -fno-common -dynamic -arch ppc -arch i386 -std=c99 -O3 -fomit-frame-pointer -Isrc/ -I/Library/Frameworks/Python.framework/Versions/2.6/include/python2.6 -c src/MD2.c -o build/temp.macosx-10.3-fat-2.6/src/MD2.o
unable to execute gcc-4.0: No such file or directory

我正在使用 Mac OS X 10.6.7 和 python 2.6.6 并安装了 XCode。
编辑:如果我添加 CC=gcc-4.2,那么我仍然会收到错误:
bash-3.2$
bash-3.2$ export CC=gcc-4.2
bash-3.2$ python setup.py build
running build
running build_py
running build_ext

bash-3.2$
编辑:似乎在这里使用 sudo 会有所不同。
我尝试按照 Adam 的建议同时使用 CC 和 CXX,但没有 sudo 时出现以下错误:
bash-3.2$ python setup.py build

如果我使用 sudo,我会在尝试使用 4.0 时收到以下错误:
bash-3.2$ sudo python setup.py build
Password:

这些额外的信息是否让正在发生的事情以及如何解决它变得更加明显?知道为什么没有 sudo 的调用会出现其他错误吗?
