Re: wrapit architecture problem

Hi Michael,

I actually meant to try the "-m64" without the "-g77". WRAPIT will try to use gfortran by default, and then g95, and then g77.
We recommend people use gfortran if possible.

You can check what mode your compiler is in by doing a "file" on the resultant executable. For example, on my Mac:

% mv size.f test.f
% gfortran test.f
ellabell[191] file a.out
a.out: Mach-O 64-bit executable x86_64
% gfortran -m32 test.f
% file a.out
a.out: Mach-O executable i386
% gfortran -m64 test.f
% file a.out
a.out: Mach-O 64-bit executable x86_64

The "x86_64" indicates it's compiling in 64-bit mode, and "i386" is 32-bit.
