linker not finding -lX11 or -l/usr/X11R6/lib/libX11.dll.a
First, thanks for responding, Yaakov.
I'm finally approaching sanity on my efforts to port xgrafix (part of xoopic, which is the main goal) to cygwin.
I finally go the library object files to comple. One of them used the prepocessor and there were some local
.h files so all I needed to do was this,
gcc -E foo.c -I./ -I/usr/include foo.o
on all the C files in the src directory.
But it won't link because when I try explicity linking like this, (I'm going to try to make the library a DLL)
gcc -shared -libXGC.dll -L/lib -L/usr/X11R6/lib -lX11 -LXpm -ltcl -ltk {list_of_objects_here}
or even when I explicity replace -lX11 by -l/usr/X11R6/lib/libX11.dll.a, the linker complains(!!!)
that it can't find X11 or /usr/X11R6/lib/libX11.dll.a, repsectively
My initial reaction was, "What the hell!!!???" Then I remembered reading in the archives that
somebody else had seen what I believe is the same problem in 2006 and solved it by pointing to
/usr/X11R6/lib/cygX11-6.dll to resolve all the functions. It was 10:30 pm and I'd promised my
wife I wasn't going to be up all night working on this so I stopped at that point, but
I'll update everyone on my progress or lack thereof, tomorrow. Meanwhile, I think this is, at
least, part of the reason why the build hasn't produced usable libraries and executable - when you run
"ar" and then "randlib" it doesn't resolve the functions in the link to the DLL so the build from the
Makefile just blithely made a static *nix archive file. The linker, will resolve the function
dependencies, but it has to see an actual archive.
But my question right now is, what's going on here? This has got to be a very well-known problem. Am I
just missing something obvious? Is there a quick fix or a patch? Should I make my own import library
from this DLL and stick it in my source directory as a better solution? Why hasn't something like this
been fixed yet, or if it has, do I need to modify some environment variable or supply some missing
command line options? Will I need to also point Xmp to this library? (Although, I'll probably find
that out myself easily enough.) Once I try this libcygX11-6 fix, or whatever fix you guys might
recommend, I'm going just try to link to the regular tcl/tk ".a" libraries to just see if that works,
since that's the only game in town unless I go get the xwindows versions from Cygwn Ports, as Yaakov
suggested earlier.
I'm just using the cygwin distribution from running setup (almost the entire distribution, though -
I added all the utlities, xwindows, scripts, tcl/tk and gnome, editors, graphics, development and
