Dear Mark,

Many thanks for you mail, I did not realised that this had to be done. I did what you said and got the following response;

Reading symbols from shared object read from target memory...done.
Loaded system supplied DSO at 0x40000000

Breakpoint 1, main (argc=7, argv=0x8f3ff4) at respgen.c:271
271 if (argc == 2

I then typed "x 0x8f3ff4" and got;

0x8f3ff4: 0x008f3d3c

If i type "break main" i get the following response;

Note: breakpoint 1 also set at pc 0x804b9cc.
Breakpoint 2 at 0x804b9cc: file respgen.c, line 271.

"x 0x804b9cc" then gave;

0x804b9cc <main+12>: 0x02087d83

This does not mean anything to me does anyone else have an ideas?

Kind Regards

Simon

You've not compiled the respgen binary with debugging symbols. To do
this, go to

$AMBERHOME/src/antechamber

do a
        make clean

then do a
        make -e AMBERBUILDFLAGS="-DDEBUG -g"

At the end of this process, the compiled respgen will be moved to
../../exe by the makefile, but gdb makes use of the sources in the same
dir, hence copy respgen back to the build dir:

        cp ../../exe/respgen .

Now run "gdb ./respgen" and when in gdb, passing commandline options using:

        run -i tp.ac -o something -f resp1


I also recommend a read of:
        http://users.actcom.co.il/~choo/lupg/tutorials/debugging/debugging-with-gdb.html

regards,

Mark
