-wwarn interfaces and array from module

albert — Wed, 23 Mar 2011 15:25:25 GMT

Dear all,

I have the followind code:
============ mod.f =============
MODULE rr_mod
INTEGER :: nbuck(1)
END MODULE rr_mod
============ overlap.f ===========
SUBROUTINE overlap_fie (overlap)
USE rr_mod
IMPLICIT NONE
INTEGER ,OPTIONAL :: OVERLAP(0:NBUCK(1)-1)
overlap = 1
END SUBROUTINE
============== tst.f =============
SUBROUTINE tst
USE rr_mod
IMPLICIT NONE
INTEGER, DIMENSION(0:nbuck(1)-1):: iover

INTERFACE
SUBROUTINE overlap_fie (overlap)
USE rr_mod
INTEGER,OPTIONAL::OVERLAP(0:NBUCK(1)-1)
END SUBROUTINE overlap_fie
END INTERFACE
call overlap_fie (overlap=iover)
RETURN
END SUBROUTINE tst

====== compilation and output =======
$ ifort -c -warn interfaces mod.f
$ ifort -c -warn interfaces overlap.f
$ ifort -c -warn interfaces tst.f
tst.f(7): error #8000: There is a conflict between local interface block and external interface block. [OVERLAP]
SUBROUTINE overlap_fie (overlap)
--------------------------------^
compilation aborted for tst.f (code 1)

As far as I can see the problem results from the fact nbuck is an array andcomes through the module rr_mod.

Any suggestion how to overcome this problem (problem is stripped from a large code packag) ?

Best Regards,

Albert

An interface body has no awareness of external (to it) constants and variables (such as NBUCK) that one may imagine to be available by host association.

It is for this purpose that the IMPORT statement was created.

In this case, NBUCK is visible through the USE RR_MOD.

I can't reproduce the problem using 12.0.2. Which compiler version are you using?

Hi Steve,

The Fortran compiler version: c11.1.059_f11.1.059

Best regards,

Albert

Ok - we've made fixes in that area since then. Please try the current compiler. I think 12.0.3 is now posted.

I'll have a try next week, see if I can persuade our sys admin to install it (otherwise I'll see if I can install it localy)

You can certainly do a local install of the compiler - I do that all the time.

I don't doubt that I can instal it, but what is the easiest way t down load the compiler (could not find a direct link to the instal package).
