我正在尝试在优胜美地上编译php（5.5.18，版本并不重要），但在链接阶段失败了。看起来有些apache符号消失了吗？
（以下在Mountain Lion上表现完美，但在优胜美地上失败了。）

有什么想法吗？我检查了/usr/lib/libapr-1.dylib（带有nm -g）并且符号不存在。我通常应该在哪里找到这些符号？这是否缺少lib？真正奇怪的是我的自定义构建脚本在10.9上正常工作但在10.10上失败
感谢您的帮助！ 尼古拉斯

原来它使用了以下包含路径：
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/include/apache2/
而不是正常的：
/usr/include/apache2/
更多信息：
$ xcodebuild -version -sdk macosx

奇怪，我希望它可以帮助其他人。
最佳， 尼古拉斯

首先安装Xcode 6.1，然后：
sudo ln -s /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/include /usr/include

我使用MacPorts安装了一些库（比如mcrypt），然后使用以下命令编译5.5.18源代码（使用Xcode命令行）./configure -command：
