--- Comment #3 from pablomme <pablomme at googlemail dot com> 2012-02-22 03:32:14 UTC --- > Please define fails. What is the error message you get? Namely: $ gfortran -o t test_etime_iface.f90 /scratch/pl275/ccyZ7sWC.o: In function `MAIN__': test_etime_iface.f90:(.text+0x4b): undefined reference to `etime_' collect2: ld returned 1 exit status gfortran accepts the inteface but ld fails because the intrinsic has been obscured by a missing external procedure. > As it is an intrinsic procedure, etime already has an > explicit interface. So, trying to re-specify > an interface makes no sense. I don't doubt that gfortran's behaviour may be sensible. The "bug" here is that it behaves differently from 6 other compilers. About whether this construction makes sense or not, in our code we use this explicit interface in order to support optional compilation of a C replacement for etime for compilers that do not offer the extension. At present, gfortran requires the C replacement because of this problem, but it shouldn't need it. No biggie, of course, but it'd be nice to see this consistency.
