I'm trying to build kiva 3v on OS X using gfortran. I had the same code compiling with intel fortran compiler, using XCode so I didn't see compiler options ifort was using.

Anyway, with gfortran I get the follow error I can't seem to find much information on:

begin.F:51.18:

      call second(tstart)                                               
                 1
Error: 'time' argument of 'second' intrinsic at (1) must be of kind 4

This is repeated several times (for each call of second it seems like). Here's the full output from the compiler.

The second looks like this:

      subroutine second (tnow)
      real*4 d(2)
      rtnow=etime(d)
      tnow=d(1)+d(2)
      return
      end

Does this indicate a problem the variable in the subroutine, or the variable being passed to it externally? Is there an option I can use to relax this "must be kind 4" requirement?

I'm at a loss of how to proceed, any advice is appreciated!
