c - 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.out without building gcc again?

(I'm assuming it should be possible with some options, but am unsure how to proceed)

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.
