No such file or directory error
I am cross-compiling a program on my PC (12.04) for my beaglebone (12.04 precise armhf). But when I try to execute the program on beaglebone:
root@omap:/home/ubuntu/helloworld# ./helloworldtest
bash: ./helloworldtest: No such file or directory
Here are some properties:
root@omap:/home/ubuntu/helloworld# file helloworldtest
helloworldtest: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.31, BuildID[sha1]=0xca0159e70b99493764b601a0195ee18be5e29b31, not stripped
root@omap:/home/ubuntu/helloworld# ls -la
total 80
drwxrwxr-x 2 ubuntu ubuntu 4096 Jul 20 07:51 .
drwxr-xr-x 5 ubuntu ubuntu 4096 Jul 20 07:50 ..
-rwxrwxrwx 1 ubuntu ubuntu 72739 Jul 20 07:42 helloworldtest
I searched net and found out that most of the people who had this problem, had it because they were using 64 bits machine to compile the code but my PC's processor is 32 bits and my beaglebone's is 32bits too.
Also the strange thing is that, I am able to run this program on beaglebone if I use Angstrom Linux, rather than Ubuntu 12.04 Precise Armhf. Therefore I am sure that there is not anything wrong with my cross-compile process and my cross-compiled program.
Probably you are going to say install ia32-libs but I cannot install ia32-libs:
root@omap:~/helloworldtest# apt-get install ia32-libs Reading package lists... Done Building dependency tree
Reading state information... Done Package ia32-libs is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source
E: Package 'ia32-libs' has no installation candidate
Here is the ldd output: (Problem seems like this?)
root@omap:/home/ubuntu/helloworld# ldd helloworldtest
not a dynamic executable
I compiled the same program on the target-machine (beaglebone) and checked its ldd output:
root@omap:~# ldd compiled_on_beaglebone
libgcc_s.so.1 => /lib/arm-linux-gnueabihf/libgcc_s.so.1 (0x400de000)
libc.so.6 => /lib/arm-linux-gnueabihf/libc.so.6 (0x400ef000)
/lib/ld-linux-armhf.so.3 (0x40086000)
Here is the readelf -hl output:
ubuntu@omap:~/helloworld$ readelf -hl helloworldtest

What can be my problem? Any suggestions or ideas?
