 Posted: Thu Oct 17, 2024 9:58 pm Post subject: Nested modules |
 |
|
I cannot understand why the intrinsic function COMPILER_VERSION cannot be accessed from the main program through the nested modules MOD1 and MOD2, but the function DBL can. The compiler warns with
| Quote: | | warning 1259 - COMPILER_VERSION is a standard intrinsic that requires USE ISO_FORTRAN_ENV. |
I must be overlooking something trivial.
| Code: | MODULE MOD1
USE ISO_FORTRAN_ENV
IMPLICIT NONE
INTEGER, PARAMETER :: M1=1
CONTAINS
INTEGER FUNCTION DBL(X)
IMPLICIT NONE
INTEGER, INTENT(IN) :: X
DBL=2*X
END FUNCTION DBL
END MODULE MOD1
MODULE MOD2
USE MOD1
IMPLICIT NONE
INTEGER, PARAMETER :: M2=2
END MODULE MOD2
PROGRAM MODTEST
USE MOD2
IMPLICIT NONE
WRITE(*,*) 'Version : ', COMPILER_VERSION()
WRITE(*,*) M1, M2, DBL(3)
END PROGRAM MODTEST |

Your code exposes a bug in FTN95.
For the time being it is necessary to move USE ISO_FORTRAN_ENV to the main program or, in general, to the subprogram that calls COMPILER_VERSION(). |
