使用 clang/LLVM 通过 LDFLAGS 链接 .dylib

我收到一个错误。

其中一个源文件引用：

#include <libxml/parser.h>

我正在使用下面的 Makefile，尝试链接：

LDFLAGS =-l../../usr/local/sys/usr/lib/libxml2.dylib

路径似乎正确，并且文件在那里。

来自 IDE 的错误详细信息：http://clip2net.com/clip/m0/1333837472-clip-29kb.pnghttp://clip2net.com/clip/m0/1333837744-clip-32kb.png

我做错了什么？
