Question

我正在尝试阅读和学习pytho2.5.6源代码，并尝试在每次对其进行一些更改时重新编译代码。

但是当我通过以下命令编写源代码时，它似乎不起作用：

./configure --prefix=/path/to/somewhere/that/don't/messup/myenv/
make

在make之后，控制台只显示如下错误：

cc1: error: unrecognized command line option "-Wno-long-double"

我搜索谷歌，似乎我使用的gcc（4.2.1）与python2.5.6无法兼容。

我的系统的一些信息：

gcc version 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.11.00)
Xcode 4.6.2(installed via the xcode command cline tool )
python2.5.6 source code(download from python.org)

我尝试过这样的解决方案：

1.download diff python代码版本，如2.5.4，并再次执行这些步骤。

2.在configure之后，修改Makefile，然后删除--Wno-long-double，但新错误如下所示：

        ➜  Python-2.5.6  make

       make: *** [Python/mactoolboxglue.o] Error 1

所以，我想知道是否有办法手动安装gcc4.0？

PS：我之所以使用python2.5.6，是因为我读了一本名为中文的书。也许最好的解决办法是阅读2.7源代码=。= .... hmmm ....

在mac os x 10.8上安装gcc4.0
