[Mvapich-discuss] Build Failure with NVHPC 23.3

[Shineman, Nat]

Louise and Sylvain,

Please try the attached patch to resolve both the real128 and the rdynamic issues. Let me know if you have any issues.

Thanks,
Nat

I ran into the exact same problem - unclear to me why config w/ NVIDIA 23. x turns on "supports fortran 2008" and then fails miserably, while NVIDIA 22. x compilers did not. Also, the config adds -rdynamic that is not supported by NVIDIA's

Hi,



I am building MVAPICH2 2.3.7 with NVHPC 23.3 which is encountering a build error.



The configure script runs successfully but when building with make I get the following error:



 make -j 8
  MOD      src/binding/fortran/use_mpi_f08/mpi_f08_types.stamp
NVFORTRAN-S-0081-Illegal selector - KIND value must be non-negative  (../mvapich2-2.3.7/src/binding/fortran/use_mpi_f08/mpi_f08_types.f90: 355)
  0 inform,   0 warnings,   1 severes, 0 fatal for mpi_sizeof_xreal128

  0 inform,   0 warnings,   1 severes, 0 fatal for mpi_sizeof_xcomplex128
make: *** [Makefile:45401: src/binding/fortran/use_mpi_f08/mpi_f08_types.stamp] Error 1



These lines refer to code using real128 datatypes.



When I compared the status of the configure, with a previously successful build with NVHPC 22.5 - the HAVE_F08_BINDING is set to 1 (with 23.3) not 0 (with 22.5).



I attempted to work around this by setting --enable-fortran=f77 but this removes the mpif90 compiler so this wasn't a viable work-around.



Is there a way of enabling f90 support without explicitly enabling f08 support? The only option I could see was --enable-fortran=fc which enables both.



Or adding a check for real128 support to the configure script for Fortran 2008 support checking?


All the best,

Louise
