Hi,
I am also trying to use a function inside the static library
libX11.a - the XLookupString function. This function is declared in
Xutil.h in the X11 directory. I used the options of LIBS => '-lX11' , INC
=> '/usr/include/X11' where the libX11.a is stored in my current
directory. I also used #include <X11/Xutil.h> in the C code. But the
out.Makefile.PL in the build directory says that -lX11 library was not
found, and I get an error saying XLookupString is not defined. A similar C
code with same compilation options works. Can someone help ?
Thanks,
Vikram
