gcc arm executable "no such file orr directory", wrong dynamic lib

Question

I am trying to make a usable setup for gcc-linaro-arm-linux-gnueabihf-4.8-2013.11 on windows. Something happens at dynamic link:

$(CC)-gcc   -o test main.c -Wall -lc

The program compiles fine, but when deployed to ARM shows: "No such file or directory"

Searching the issue, seems that static build works but executable is huge:

$(CC)-gcc   -static -o test main.c -Wall -lc

Now I have a VisualGDB toolchain installed that builds (in IDE) with it's own toolchain a similar executable (small, dynamic) that works so I guess this is nothing wrong with my ARM distribution.

Am I missing something or wrong include from gcc-linaro-arm-linux-gnueabihf-4.8-2013.11 ?

Thanks very much in advance,

One more investigation:

file test

test: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.16, not stripped

Answer 1

I solved by myself, thanks for support anyhow.

The cross-compiler from Linaro links with a new lib name (some name changes in Debian) such as /lib/ld-linux-armhf.so.3 but the BBB (default) distribution use a old name /lib/ld-linux.so.3. Both names should point (symlinks) on BBB to real used library which is ld-2.16.so

So create another symlink and that's it.

ln -s /lib/ld-2.16.so /lib/ld-linux-armhf.so.3

-rwxr-xr-x 1 root root 130304 Mar 20  2013 /lib/ld-2.16.so
lrwxrwxrwx 1 root root     15 Dec 24 23:14 /lib/ld-linux-armhf.so.3 -> /lib/ld-2.16.so          <-- new one
lrwxrwxrwx 1 root root     10 Jun 19  2013 /lib/ld-linux.so.3 -> ld-2.16.so

Best regards and Merry Christmas to all,

Answer 2

It might well be a missing shared library on the deployment machine.

Try running $(CC)-readelf -d your-binary | grep NEEDED. This will display the names of the required shared libraries. Verify that they are present on the target machine

Try running ldd you-binary on the target machine. It should report what are the required dynamic libraries and if they have been found.

PS. Run the program on the target with strace your-binary. Look for open or access calls, which return error ENOENT.
