error #6405: The same named entity from different modules and/or program units cannot be referenced

I have read Stve Lionel's explanation,but I still don't get it.
ifort -c ircg.for

I try to put 4 arrays into one.These 4 arrays are defined in module mt2dsens.

Judging from Steve Lionel's points, he has only around ten-thousand posts; so, looking for the specific one that you alluded to should be a good test of the search features of the forum software, but I am sufficiently negatively biased about its capabilities to not even try.

You have, in file ircg.for, the following subroutine heading:

[fxfortran]        subroutine transenpas(group,apr1dsens,
     &  apr2dsens,apr3dsens,apr4dsens)
...
       use params
       use mt2dsens
...
[/fxfortran]

but module mt2dsens, which is USEd in the subroutine, already contains declarations for subroutine arguments 2, 3, 4 and 5:

[fxfortran]        real*4 apr1dsens(npmax,ncs)
        real*4 apr2dsens(npmax,ncs)
        real*4 apr3dsens(npmax,ncs)
        real*4 apr4dsens(npmax,ncs)
[/fxfortran]

Even if the duplicated declarations match perfectly as to type, size, etc., such redeclarations of entities already associated through USE statements are not allowed.

Thanks mecej,I will use interfaces.
