Can't run program in debugger?

问题:

I was trying to use gdb on a program earlier on a Linux 64-bit machine, and I ran gdb bomb (that's the program name), and within gdb, I simply typed in ran. It came back with the error /bin/bash: /home/imicrothinking/ics11302016004/lab2/bomb: No such file or directory During startup program exited with code 127.

I've dug around the net for a bit, and suggestions I've heard so far led to no concrete solutions, here's what I'm sure of so far:

1. I'm logged on as a root level user.
2. I haven't gone to the wrong directory.
3. The executable file definitely exists.

I'd welcome all suggestions.

maybe gdb cann't find your shell. so set the env var SHELL to your shell. eg: export SHELL=/bin/bash
