macos - 在 Mac OS X Mountain Lion 上编译 apache2 的问题

Question

在我的 Mac (10.8) 上尝试编译最新版本的 apache Web 服务器 (2.4.3) 时，我遇到了问题。当我运行 ./configure 命令时，我得到以下输出:

checking for chosen layout... Apache
checking for working mkdir -p... yes
checking for grep that handles long lines and -e... /usr/bin/grep
checking for egrep... /usr/bin/grep -E

See `config.log' for more details

以下是日志文件中的最后几行:

正如您在日志输出中看到的，./configure 中的脚本找不到我的 C 编译器的路径，因为它位于 /Applications/Xcode.app/Contents/Developer/usr/bin/cc 而不是在 /Applications/Xcode.app/Contents/Developer/Toolchains/OSX10.8.xctoolchain/usr/bin/cc 中，如日志输出中所述你可能会说，解决办法很简单，我所要做的就是修改configure脚本，对吧？问题是我对 shell 脚本一无所知，这就是为什么我在过去的 3 个小时里一直在努力解决这个问题。请帮助。提前致谢。

我刚刚在this post I created and answered中遇到了类似的问题所以我想我应该分享我的发现。只需通过执行以下操作即可创建符号链接(symbolic link):

# Create a symlink to default Xcode toolchain for OS X lion
sudo ln -s \
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain \
/Applications/Xcode.app/Contents/Developer/Toolchains/OSX10.8.xctoolchain

# Create a symlink to default Xcode toolchain for OS X maverick
sudo ln -s \
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain \
/Applications/Xcode.app/Contents/Developer/Toolchains/OSX10.9.xctoolchain

并且您至少应该进入下一步。
