Zedboard Linux Hello world execution failure

No such file or directory!

On trying to execute the hello_world.elf file I ran into a ./hello_world.elf: No such file or directory error.

The problem was due to a missing interpreter that was provided in the elf file.

readelf -a hello_world.elf

results in a big output.

If yo check the Program Headers section you see the following output:

The Requesting program interpreter is our problem here.

That file is not available on the zerboard’s /lib directory.

Thus just simply create a symbolic link of the interpreter on the zedboard

ln -s /lib/ld-2.17.so /lib/ld-linux-armhf.so.3
