Possible Duplicate:
Creating ELF instead of a.out

When I use the command gcc hello.cpp, I end up with a.out.

I read somewhere that a.out files are different from ELF executables.

How do I instruct gcc to create ELF executable?

    In fact, gcc uses the name a.out for historical reasons. You’re actuall getting an ELF executable. You can verify this with the file command, which will give you output along the lines of:

    $ file a.out
a.out: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.32, not stripped
