在 Python 中使用 Pygsl 和 GCC 4.0

Question

我正在尝试使用最新版本的 GCC 安装 pygsl，即：

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

我收到错误：

$ sudo python setup.py build
numpy

知道可能是什么原因造成的吗？ 谢谢。

尽管安装了 gcc-4.2，但您会看到构建正在使用 gcc-4.0——令人困惑。
“gcc-4.0”从哪里来？也许是setup.py，
或~/.pydistutils.cfg，或export CC-gcc-4.0或...只是猜测，我没有pygsl。
你能把 gcc-4.0 排除掉吗，如中所述
所以 setting-gcc-4 -2-as-the-default-compiler-on-mac-os-x-leopard ？
