Craig,

'makelog' is the log file from the McIDAS-X build.  It shows the commands
run to compile and link programs and any errors/warnings that were emitted
by the compilers.  'makelog' is located in the ~mcidas/mcidas7.6/src
directory.

Right.

OK.

>Everything was fine after that.

Excellent.

>Main Point: makelog is a good place for sample information.

Thanks for the follow-up.

>Thanks for your concern.

No problem.

This is easy enough, but not as obvious as it might seem.

Test window?  Do you mean Text window?

Yes, to get good information from a debugger, all routines in an executable
should be compiled in debug mode (-g).  I routinely, however, only compile
the modules I am looking at in debug mode, but then again, I am working
on a Sun and using dbx.  The lack of verbose information about other
routines in the executable _usually_ does not matter to me.  What counts
is line information in the module I am working on.

Since I don't have any experience with the HP debugger, I am afraid I
can't provide any detailed help; sorry.  Do you get no useful output
enven though your stuff is compiled with debug on?

>Can you tell me if you can think of some steps that I have missed?

I see that you are includeing the strip option in your link run of
'mccomp':

mccomp -s

Try leaving off stripping so that the symbol table remains in your
code.
