剛剛安裝了XCode 4.3，現在無法安裝mysql-python軟件包。我使用的OS X Lion 10.7.4，XCode 4.3，自制軟件，都是在幾個小時前安裝的。使用homebrew'ed蟒蛇2.7.3，MySQL的5.5.25無法使用XCode 4.3編譯mysql-python 4.3/homebrew
這裏是輸出：

有沒有一種辦法手動修改三月標誌？
UPDATE：
哦，我還安裝了命令行工具（Xcode中 - >設置 - >下載），這顯然是GCC-4.2創建鏈接：
(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從其他源安裝的編譯器。 gcc-4.2 --version是什麼意思？ –
@NedDeily，好像命令行工具創建的鏈接（的Xcode>首選項>下載...） （盧卡斯） - >這GCC-4.2 /usr/bin/gcc-4.2 （盧卡斯） - > LS -l'其中gcc-4.2' lrwxr-xr-x 1個根輪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（基於Apple Inc. build 5658）（LLVM build 2336.9.00） ... – lukaszb
據我所知，Apple的命令行工具不要爲gcc-4.2安裝一個符號鏈接（我剛剛證實，剛纔發佈的Xcode 4.3.3及其命令行工具沒有改變）。但是它所鏈接的llvm-gcc是最新的Apple gcc。所以這不是問題。這些標誌通常不適用於任何Apple編譯器;他們通常使用'-arch'。這可能是由一個雜散的環境變量設置注入的，如CFLAGS或LDFLAGS。另外，通過運行mysql_config來檢查mysql配置中記錄的內容; MySQL-python着眼於它。 –
