Executable unable to run

kakikomi · 03-28-2010, 10:51 PM

This is what I have done. I cross compiled a simple C++ "hello world" application in Cygwin that targets an embedded machine running uclinux on powerpc405. I can see that it is an ELF file. So I transefered the executable to the target machine. When I attempted to run the executable I get

-sh: ./a.out: not found

I can swear that the file is indeed where it is. May I have so some help/hint to the problem causing this?

Use

$ ls ./a.out

..to confirm if the file is there or not. If it's not, use

$ ls

..to see which files are there. I suspect Cygwin has named the file a.exe instead of a.out?

Yes the file exist and I am not running it in Cygwin but in the embedded machine. The executable was crossed compiled

What's output of

Code:

ldd ./a.out

on embedded system ?

Oh...I get the idea, you suggest that I find out the shared libraries my program is using. Unfortunately the embedded machine does not have ldd. so I used objdump on the development host to list out the shared libraries used and it seems that the libraries required are not on the target machine. Guess that`s the problem.

Thanks.
