You can't use gdb on shell scripts.

But one can invoke 'gdb' from the innermost shell script.
Regards,
Sergei.
From what I can tell the two shell scripts do nothing useful(?! why
have them?) and within the hidden folder src/.libs there exists a binary
called lt-octave
To any future people who have this problem - point the IDE to it, I do
not know why it is hidden or so far from the root-directory, if I find
out I will follow up but it doesn't seem to matter......
Alec
Well, in my case:
"
file /home/sergei/AFSWD/install/octave-3.6.2/bin/octave-3.6.2
/home/sergei/AFSWD/install/octave-3.6.2/bin/octave-3.6.2: ELF 32-bit LSB
executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.6.4, dynamically
linked (uses shared libs), not stripped
"
- this is self-built Octave.
So I am sure where the shell script comes form.
Regards,
Sergei.
