我正在尝试在MountainLion上使用XCode Version 4.4.1 (4F1003)构建mod_auth_openid,但是出现了关于'cc'命令缺失的错误,具体如下:
/usr/share/apr-1/build-1/libtool --silent --mode=link /Applications/Xcode.app/Contents/Developer/Toolchains/OSX10.8.xctoolchain/usr/bin/cc -o mod_auth_openid.la -rpath /usr/libexec/apache2 -module -avoid-version libmodauthopenid.la -I/usr/include/apache2 -I/usr/include/apr-1 -I/usr/local/include -L/usr/local/lib -lopkele -lcurl -lexpat -ltidy -lssl -lcrypto -lz -L/usr/lib -lpcre -lcurl
/usr/share/apr-1/build-1/libtool: line 4574: /Applications/Xcode.app/Contents/Developer/Toolchains/OSX10.8.xctoolchain/usr/bin/cc: No such file or directory
apxs:Error: Command failed with rc=8323072
该怎么办?
