"No such file or directory" when running app on linux arm target

Question

I have a development kit ( Altera Cyclon V, Cortex A9) and I'm trying to run a simple app on it. I'm using cygwin for cross compiling my code for ARM Linux (using soureforge toolchain for Linux ).

Steps :

1. build within cygwin : arm-linux-gcc dd.c -s -mcpu=cortex-a9 -s -o ddb
2. copy ddb to target and chmod a+x
3. running it gives me "./ddb: No such file or directory" . probably a mismatch between lib\tools but I'm new to Linux ( coming from QNX ).

Target is running :

   root@socfpga:~/altera# cat /proc/version 
   Linux version 3.9.0 (jdasilva@sj-interactive3) (gcc version 4.7.3 20121106 (prerelease) (crosstool-NG linaro-1.13.1-4.7-2012.1
   1-20121123 - Linaro GCC 2012.11) ) #1 SMP Fri Sep 27 22:55:43 PDT 2013

File data of my app :

 ddb: ELF 32-bit LSB executable, ARM, version 1, dynamically linked (uses shared
 libs), for GNU/Linux 2.6.33, stripped

File data of a sample hello_world that runs on target :

 hello: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (use
 s shared libs), for GNU/Linux 2.6.31, BuildID[sha1]=0x2e8fbebd0bdab5897c0c65fb6b
 563f3c34a16eb1, stripped

I can see that different DLL are being used ( 2.6.31 vs 2.6.33 ).

How can I solve this?

Answer 1

I've had that problem before when I tried to copy ARM binaries to an ARM android device.

You solved it, but either way, this is what I found out. The problem was the shared libraries. It is trying to load a library that doesn't exist on the target. The "file not found" error is very misleading.

Answer 2

could be 64<>32bit problem. See this
