Creating ELF instead of a.out

Question

I need to generate a simple \"Hello World\" ELF32 executable using gcc. I don\'t seem to have the gcc-elf command though. Is it possible to create ELF binaries instead of a.

Answer 1

Check the file a.out

$ file a.out
a.out: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs), for GNU/Linux 2.6.9, not stripped

I believe the default name is retained as a.out but the format is ELF.
