mac編譯apache時出現 checking whether the C compiler works... no 的解決辦法

在MAC下編譯apache時執行 ./configure 出現如下錯誤。

checking for gcc... /Applications/Xcode.app/Contents/Developer/Toolchains/OSX10.9.xctoolchain/usr/bin/cc

checking whether the C compiler works... no
configure: error: in `/Users/hufeiyan/ws/httpd-2.2.26':
configure: error: C compiler cannot create executables

See `config.log' for more details

查看config.log有如下描述：

configure:4480: result: /Applications/Xcode.app/Contents/Developer/Toolchains/OSX10.9.xctoolchain/usr/bin/cc

解決辦法：

在命令行執行如下命令：

sudo ln -s /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/ /Applications/Xcode.app/Contents/Developer/Toolchains/OSX10.9.xctoolchain

OK，再次運行 ./configure 順利完成配置
