Nevermind I got it from this

I have 2 .f90 files.

file: mod_def.f90

module definedmod
integer :: a = 4
end module definedmod

file: use_mod_def.f90

program usemod
use definedmod
	print *, a
end program usemod

I succeeded in compiling the module definition file using this command:

ifort -c mod_def.f90

THis generated a .obj and .mod file which is good. However when I try to compile the main program

ifort use_mod_def.f90

I get a big error

use_mod_def.exe : fatal error LNK1120: 1 unresolved externals

How do I compile the main program and have it recognize the use module?

As a side notes the online help docs don't provide a working example. They only gloss over some generalities. It would be good to have working examples that users can copy, paste and work with...

Thanks and look forward to your responses.

Nevermind I got it from this thread https://software.intel.com/en-us/forums/intel-visual-fortran-compiler-for-windows/topic/290070

what I did was:

>ifort -c mod_def.f90

>ifort use_mod_def.f90 mod_def.obj

Then I got the executable.
