整了一个星期多了，一点头绪都没有，所以想请教下各位要如何成功地编译linphone。我之前是在10.7系统&xcode4.1下编译，最后一步编译静态库make all的时候，出现error错误。。
然后换成10.7.4+xcode4.3.3/4.4.1，在执行sudo port install coreutils automake autoconf libtool intltool wget pkgconfig cmake gmake yasm grep doxygen ImageMagick optipng
的时候报错如下
Error: No Xcode installation was found.
Error: Please install Xcode and/or run xcode-select to specify its location.
Error:
Warning: xcodebuild exists but failed to execute
Warning: Xcode does not appear to be installed; most ports will likely fail to build.
请问各位都是怎么样变异的呢？感谢赐教！！
