Variation between Fortran files #157

Open cponder opened 5 months ago

cponder commented 5 months ago

If I read right, the files under src/testlib are F77 compliant, while the 

   src/components/sysdetect/tests/query_device_simple_f.F

is written in F90 format. You special-case this

26 ifeq ($(notdir $(F77)),gfortran) 27 FFLAGS +=-ffree-form -ffree-line-length-none 28 else ifeq ($(notdir $(F77)),flang) 29 FFLAGS +=-ffree-form 30 else ifneq ($(findstring $(notdir $(F77)), $(intel_compilers)),) 31 FFLAGS +=-free 32 else ifneq ($(findstring $(notdir $(F77)), $(cray_compilers)),) 33 FFLAGS +=-ffree 34 endif

in the file

   src/components/sysdetect/tests/Makefile

I'm testing the "nvfortran" compiler, so it's not triggering the corresponding "-Mfree" flag. And if I set it in general

    export FFLAGS="-noswitcherror -Mfree"

it will try to treat the F77 files as F90 and break the compile. As I understand the Fortra standard, if you change the name of the latter file to

    src/components/sysdetect/tests/query_device_simple_f.f90

the compilers will automatically treat the file as free-form and you won't have to use the special-casing in the Makefile.

I'm using PAPI 7.1.0 with the NVHPC 24.1 compilers. BTW, it was a lot easier to build this than 6.0.0.

Can you please check in your environment if adding the following two lines under line 27 in the Makefile solves the problem?

else ifeq ($(notdir $(F77)),nvfortran) FFLAGS +=-Mfree

Thanks, Anthony
