刚刚安装了XCode 4.3，现在无法安装mysql-python软件包。我使用的OS X Lion 10.7.4，XCode 4.3，自制软件，都是在几个小时前安装的。使用homebrew'ed蟒蛇2.7.3，MySQL的5.5.25无法使用XCode 4.3编译mysql-python 4.3/homebrew
这里是输出：

有没有一种办法手动修改三月标志？
UPDATE：
哦，我还安装了命令行工具（Xcode中 - >设置 - >下载），这显然是GCC-4.2创建链接：
(lukasz) ~ > which gcc-4.2
/usr/bin/gcc-4.2
(lukasz) ~ > ls -l `which gcc-4.2`
lrwxr-xr-x 1 root wheel 12 12 Jun 01:36 /usr/bin/gcc-4.2 -> /usr/bin/gcc
(lukasz) ~ > gcc-4.2 --version

...
Xcode 4.3不提供'gcc-4.2'，因此您似乎正在使用从其他源安装的编译器。 gcc-4.2 --version是什么意思？ –
@NedDeily，好像命令行工具创建的链接（的Xcode>首选项>下载...） （卢卡斯） - >这GCC-4.2 /usr/bin/gcc-4.2 （卢卡斯） - > LS -l'其中gcc-4.2' lrwxr-xr-x 1个根轮12 12 6月01:36 /usr/bin/gcc-4.2->/usr/bin/gcc （lukasz）〜> gcc-4.2 - 版本 i686-apple-darwin11-llvm-gcc-4.2（GCC）4.2.1（基于Apple Inc. build 5658）（LLVM build 2336.9.00） ... – lukaszb
据我所知，Apple的命令行工具不要为gcc-4.2安装一个符号链接（我刚刚证实，刚才发布的Xcode 4.3.3及其命令行工具没有改变）。但是它所链接的llvm-gcc是最新的Apple gcc。所以这不是问题。这些标志通常不适用于任何Apple编译器;他们通常使用'-arch'。这可能是由一个杂散的环境变量设置注入的，如CFLAGS或LDFLAGS。另外，通过运行mysql_config来检查mysql配置中记录的内容; MySQL-python着眼于它。 –
