在Python中使用Pygsl与GCC 4.0

Question

我正在尝试用最新版本的GCC来安装pygsl，也就是：

$ gcc --version
i686-apple-darwin10-gcc-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5659)

但是我遇到了这个错误：

$ sudo python setup.py build
numpy
Building testing ufuncs!
running build
running build_py
running build_ext
building 'errno' extension

有没有人知道这可能是什么原因呢？谢谢。

虽然你已经安装了gcc-4.2，但你发现构建过程中却在使用gcc-4.0，这让人感到困惑。那“gcc-4.0”是从哪里来的呢？可能是来自setup.py，或者是~/.pydistutils.cfg，又或者是通过export CC-gcc-4.0设置的，当然这只是猜测，因为我没有使用pygsl。
你能按照SO上提到的设置gcc-4-2为Mac OS X Leopard上的默认编译器的方法，把gcc-4.0处理掉吗？
