Hi,

is there any gfortran option and/or version information available from/in a binary? Maybe accessible with objdump or strings?

For ifort, we use the -sox option ("This option tells the compiler to save the compilation options and version number in the executable file. ..."). This enables e.g.
strings /path/to/binary | grep Intel

Or is there a gfortran option that makes this accessible in a binary?

Thanks,
Kay
