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
working (compiled with VisualGDB toolchain)
test: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.16, not stripped
mot working (compiled with gcc-linaro-arm-linux-gnueabihf-4.8-2013.11)

I run -readelf (for non working):
