linking .dylib via LDFLAGS using clang/LLVM - c++

Question

I am getting an error.
One of the source files references:
#include <libxml/parser.h>
I am working with a Makefile below, trying to link:
LDFLAGS =-l../../usr/local/sys/usr/lib/libxml2.dylib
Path appears to be correct, and the file is there.
Error details from IDE:

What am I doing wrong?

Answer 1

You actually may have two problems. I suggest you try:
Add -I../../usr/local/sys/usr/include to your CFLAGS to make it find the header.
Change the LDFLAGS to -L../../usr/local/sys/usr/lib, add LIBS=-lxml2 and change the linker invocation to $(LD) $(LDFLAGS) -o $(OUTDIR)/$(NAME) $(OBJ) $(LIBS) (i.e. add the -l at the end, the -L at the beginning of the linker command line).

Answer 2

-l is for specifying the library name only. Use -L to add directories where libraries will also be looked for:
LDFLAGS += -L../../usr/local/sys/usr/lib -lxml2
Hope this helps.
