gdb "run" with error "...Cannot execute: No such file or directory"

Question

I am Ubuntu 10.04 user and I wrote a very simple program, which I compiled with gcc:

xyz@xyz-desktop:~/xyz/projects/C\C++/epollsvr/src$ gcc -g -o test test.c

Then I loaded it with gdb:

xyz@xyz-desktop:~/xyz/projects/C\C++/epollsvr/src$ gdb test

Then I ran it:

(gdb) run

Starting program: /home/xyz/xyz/projects/C\C++/epollsvr/src/num*
/bin/bash: /home/xyz/xyz/projects/CC++/epollsvr/src/num: No such file or directory
/bin/bash: line 0: exec: /home/xyz/xyz/projects/CC++/epollsvr/src/num: cannot execute: No 
such file or directory

During startup program exited with code 126.
(gdb)

Could anybody tell me why is this happening? Thanks in advance.

It doesn't look like you're running the correct program… The first line from gdb should be Starting program: …/test… Are you sure you're running exactly the commands you've shown here? — David Wolever

Try checking your path:

Starting program: /home/xyz/xyz/projects/C\C++/epollsvr/src/num*

it has C\C++ in it whereas gdb says:

/bin/bash: /home/xyz/xyz/projects/CC++/epollsvr/src/num: No such file or directory

C\C++ is made into CC++. I would guess that's why it can't find the file.

My point is try running it from a different location which wouldn't have C\C++ in the path.

Thanks! It works like a charm now. So, this thread is closed.
