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
path似乎是正确的，并在那里的文件。

我究竟做错了什么？

你其实可能有两个问题。 我build议你尝试一下：
将-I../../usr/local/sys/usr/include到您的CFLAGS中以使其find标题。
将LDFLAGS更改为-L../../usr/local/sys/usr/lib ，添加LIBS=-lxml2并将链接器调用更改为$(LD) $(LDFLAGS) -o $(OUTDIR)/$(NAME) $(OBJ) $(LIBS) （即在末尾添加-l ，在连接器命令行的开始处添加-L ）。
-l仅用于指定库名称。 使用-L来添加库也将被查找的目录：
LDFLAGS += -L../../usr/local/sys/usr/lib -lxml2
希望这可以帮助。
