GCC queries: identify versions and compiler flags used

[kcy29581]

Hi all,

I have put the questions here as I'm using Ubuntu at work. However, I think the Gentoo crowd should be able to help.

I work as a video games tester, and I need some help regarding GCC. These are regarding tests that I need to perform.

Things I need to identify:
- What version of the GCC compiler was used to compile our games, and
- Identify what compiler flags were used by our development teams

Please note, I only have the final product, not the source code.

I believe I know how to identify the GCC version used; I use the following command on .BIN files:

As far as I know there is no way, unless the application itself records the information somewhere (like the kernel does in /proc/version - even the kernel doesn't store the actual compiler command line, though). The result of your grep command there simply gives the version(s) of libgcc used by symbols in the binary - same as grepping the strings output for GLIBC would give the minimum versions of glibc required by various symbols.

Realistically, I strongly doubt that you have any chance of figuring out the compiler and command line used to build a given binary without access to its makefile.

Couldn't you just send an email to the dev and say "Hey man, what version did you use and what flags did you use?"

And obviously explain why. They'll probably be shocked that a game tester really knows shit about coding.
