Hello Richard,
I'm not certain this will do the trick, but you may need to have your
LD_LIBRARY_PATH set to include the current directory.
If this does not help, I'd suggest you a gzipped copy of your external library
to MUG so I can see if I can repeat the problem.
Could you also send the output of:
ldd mwrap_hello.so
for the wrapper built by Maple - just to verify that it is indeed linked to
libtestprg.so.
Sincerely,
Allan Wittkopf
