Did you try ctypes? >>> from ctypes import * >>> sample=cdll.sample.sample_ >>> sample.restype=None >>> sample.argtypes=[POINTER(c_int), POINTER(c_int), POINTER(c_double), POINTER(c_double)] >>> e1 = c_int(0) >>> e2 = c_int(0) >>> ain = (c_double*3)(2.0, 3.0, 4.0) >>> aout = (c_double*4)() >>> sample(e1, e2, ain, aout) >>> aout[:] [6.0, 9.0, 8.0, 12.0] >>> e1.value 0 >>> e2.value 0 I compile the SAMPLE example with mingw g77 3.4.5: g77 -shared -o sample.dll sample.for I had to take out the "INTENT(OUT)"s because g77 didn't like them. And "SAMPLE" became "sample_" in the dll. Also note that argument passing to Fortran subroutines is strictly pass-by-reference. Thus the ain pointer.
