-m64 flag doesn't seem to work

[pDs]

Greetings, 

I've compiled a project from source with the command:

ifort -c ../Source/*/* -std90 -m64

Next, I try to link all the binaries with 

ifort * -o runfile

This generates the warning 

ld: warning: ld: warning: ld: warning: ld: warning: ld: warning: ignoring file noise_general.mod, file was built for unsupported file format ( 0x0C 0x00 0x01 0x00 0x93 0x01 0x00 0x00 0x04 0x00 0x00 0x00 0x6B 0x38 0x32 0x30 ) which is not the architecture being linked (x86_64): noise_general.modld: warning: ld: warning: ignoring file nwtc_const.mod, file was built for unsupported file format ( 0x0C 0x00 0x01 0x00 0x5F 0x04 0x00 0x00 0x09 0x00 0x00 0x00 0x6B 0x38 0x32 0x30 ) which is not the architecture being linked (x86_64): nwtc_const.modignoring file airfoilparams.mod, file was built for unsupported file format ( 0x0C 0x00 0x01 0x00 0x01 0x04 0x00 0x00 0x0D 0x00 0x00 0x00 0x6B 0x38 0x32 0x30 ) which is not the architecture being linked (x86_64): airfoilparams.modignoring file nwtc_aero.mod, file was built for unsupported file format ( 0x0C 0x00 0x01 0x00 0xAE 0x09 0x00 0x00 0x16 0x00 0x00 0x00 0x6B 0x38 0x32 0x30 ) which is not the architecture being linked (x86_64): nwtc_aero.modignoring file noise_inputs.mod, file was built for unsupported file format ( 0x0C 0x00 0x01 0x00 0x92 0x06 0x00 0x00 0x18 0x00 0x00 0x00 0x6B 0x38 0x32 0x30 ) which is not the architecture being linked (x86_64): noise_inputs.mod

So it seems the -m64 flag is being ignored by the compiler. How do I resolve this?

Best Regards,

Instead of linking all files (which is what you get with the simple * expression)  try

ifort *.o  -o runfile

This will link the object files, but not the .mod files.   

Please note that .mod files are not readable by the linker/loader no matter whether you've got -m64 on the command line or not.   These are files generated for use by the compiler.
