Summary: OpenMP compilation errors
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: major
Priority: P3
Component: fortran
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: Jose.Pascual-Gutierr@1-ACT.com
I have the following OpenMP Fortran95 test program called test.f90.
PROGRAM test
USE OMP_LIB, ONLY: OMP_SET_NUM_THREADS
IMPLICIT NONE
INTEGER, PARAMETER :: numthreds = 4
INTEGER, PARAMETER :: maxnumber = 12
INTEGER :: totalsum, add, number
CALL OMP_SET_NUM_THREADS (numthreads)
totalsum = 0
add = 1
!$OMP PARALLEL DO &
!$OMP SCHEDULE(DYNAMIC,1) &
!$OMP DEFAULT(SHARED) &
!$OMP PRIVATE(number1, &
number2) &
!$OMP REDUCTION(+:totalsum)
DO nunmber = 1, maxnumber
totalsum = add + totalsum + number
END DO
!$OMP END PARALLEL DO
WRITE (*,*) totalsum
END PROGRAM test
I try to compile it with the command "gfortran -fopenmp test.f90". The compiler
returns with the following error message:
test.f90:16.24:
!$OMP PRIVATE(number1, &
1
Error: Syntax error in OpenMP variable list at (1)
test.f90:17.16:
number2) &
1
Error: Unclassifiable statement at (1)
test.f90:18.8:
!$OMP REDUCTION(+:totalsum)
1
Error: Unclassifiable OpenMP directive at (1)
test.f90:24.23:
!$OMP END PARALLEL DO
1
Error: Unexpectged !$OMP END PARALLEL DO statement at (1)
It is clear that the erros are caused by the !$OMP PRIVATE line. It seems that
a list of variables cannot be broken in two lines. Had I had
!$OMP PRIVATE(number1,number2) &
instead of the two lines connected with the & sign, I would have not had any
compilation errors. I wanted to try breaking the line, though, because in my
codes I have very long lists of private variables. In the previous compiler I
used, namely Intel's ifort, I had no issues. Do you have any suggestions when
it comes to long lists of private variables? Should I simply have several
!$OMP PRIVATE ([var1],[var2],...,[varn])
lines each opening and closing the bracket?
Thank you very much

How about adding a !$OMP at the beginning of the continuation line? Thus,
try:
!$OMP PRIVATE(number1, &
!$OMP number2) &

I just tested with some other compilers:
ifort accepts the invalid code, PathScale and Open64 show a similar syntax
error as gfortran, and PGI has a somewhat more legible error message:
PGF90-S-0155-Illegal continuation (test.f90: 17)
For the correct syntax, cf. OpenMP spec at
http://openmp.org/wp/openmp-specifications/

It seems to work this way. thank you very much.

Yeah, see OpenMP 3.0, section 2.1.2 for details how OpenMP Fortran free form
directives and their continuations look like.
