gdb giving wierd error

I was checking a program I'm working on with valgrind for memory leaks and apparently it found an invalid memory access and threw a segfault. It wouldn't tell me where it happened (well, it did, but I need more info) so I decided to check it out with gdb. Except now whenever I run gdb and try to "run" the program, I get this error:

Starting program: *name of program*
Cannot exec : No such file or directory.

Program exited with code 0177.
You can't do that without a process to debug.

I can check ANY program with gdb and it gives this same error. When I try to use Anjuta to debug the program it gives similar error messages.

Anyone have any idea what's wrong?

Edit: It works when I login as root, but not as a regular user.

I had a similar problem a while back. gdb is not finding your shell. You need to set the env var SHELL to whatever you're wanting to use. eg. /bin/csh

thanks for help...I had similar thing..and this helps..thanks again.

Just a post to give props to the answerer. I was working in a chroot environment, which had inherited my SHELL variable as /bin/bash. Since I was in busybox, it only had /bin/sh. Once I fixed that, gdb works fine again. Nice work.

Original error:

Code:

(gdb) exec-file a.out

(gdb) r

Starting program: /a.out

Cannot exec /a.out -c exec /a.out .

Error: No such file or directory

During startup program exited with code 127.

fix:

Code:

# export SHELL=/bin/sh
