Re: is there a way to find out gfortran version and/or options from a given binary?

[Kay Diederichs]

I tried your suggestion below, but it does not store the options unless the -g option is used.

If -g is not used, no option info is in the executable.

Best wishes,
Kay

If -g is used, the executable _always_ has version and option info (no extra code invoking compiler_version() and compiler_options() is needed). Just use strings <binary> | grep GNU .
