I'm porting a locally written X11 graphics program which is a combination of
Fortran and C to my Mac running OS X 10.2.6. I'm using gcc 3.3 (not the
Apple version) and g77 3.3 to compile it. Linking is done with g77 with the
-lc option included. I recently built OSF Geomview (all C code) successfully
with the same compiler configuration as well as many Fortran codes of
varying complexity, so I do have some confidence in this compiler
configuration. Other X11 applications work properly, including xterm,
Geomview, GMV, xcalc, etc.
The program I'm porting was originally a Linux program that has worked for
many years. My problem: the compiled program successfully initializes (it
seems so, anyway) an X-window, but the window remains totally blank
throughout the session. During the compilation, there are no complaints from
the compiler, and it apparently found the needed C header files in
/usr/X11R6/include/X11 and the required library libX11.a in /usr/X11R6/lib.
There were no missing object files reported. The program's menu works (if
somebody tells me what keys to hit while looking at the Linux version) and
the code even successfully writes postscript output files of the unseen "on
screen" graphics.
Has anyone seen this blank X11 window behavior? I'm mostly a Fortran
programmer and mostly a user (not a programmer) of X11, but it would be nice
to get this application working. Any ideas about where to start?
