Build error with NAG 7.2: Option error: Unrecognised option -pthread

[mathomp4]

So this is...interesting. I've had issues building Open MPI 5 with NAG 7.2 where the symptom was:

make[3]: Entering directory '/ford1/share/gmao_SIteam/MPI/src/openmpi-5.0.2/build-nag-7.2.01/ompi/mpi/fortran/mpif-h'
  CCLD     libmpi_mpifh.la
/usr/bin/ld: unrecognized option '-pthread'
/usr/bin/ld: use the --help option for usage information

Through the efforts of @ggouaillardet, he provided me with a tarfile that does work along with open-mpi/ompi#12458 to fix in the future.

So, I thought, well, Open MPI + NAG doesn't build mpi_f08 yet, but MPICH does (or did last time I tried long ago). So I grabbed MPICH 4.2.2 and configured like:

../configure \
   CC=gcc CXX=g++ FC=nagfor \
   MPICHLIB_FFLAGS='-mismatch -fpp' MPICHLIB_FCFLAGS='-mismatch -fpp' --enable-f08 \
   CFLAGS="-I/ford1/share/gmao_SIteam/nag/7.2.13/lib/NAG_Fortran" \
   --prefix=/ford1/share/gmao_SIteam/MPI/mpich/4.2.2/nag-7.2.13 |& tee configure.nag-7.2.13.log

where the options are from places on the web (like this). I don't exactly remember, but this worked before.

And when I do so, the make step dies with:

make[2]: Entering directory '/ford1/share/gmao_SIteam/MPI/src/mpich-4.2.2/build-nag-7.2.13'
  GEN      lib/libmpifort.la
libtool: warning: '/ford1/local/gcc/gcc-12.1.0/lib64/libatomic.la' seems to be moved
NAG Fortran Compiler Release 7.2(Shin-Urayasu) Build 7213
Option error: Unrecognised option -pthread
make[2]: *** [Makefile:6158: lib/libmpifort.la] Error 2

Well, that's familiar.

My guess is it must be something similar in Autotools?

For what its worth, I just tried

FC=nagfor ./configure

and it builds successfully. The NAG version:

NAG Fortran Compiler Release 7.0(Yurakucho) Build 7048

In checking, the mpi_f08 was disabled by configure. Checking config.log:

So it has issue compiling the following:

TYPE(*), DIMENSION(..) :: A, B, C

From https://www.mpi-forum.org/docs/mpi-4.1/mpi41-report/node467.htm:

A high quality MPI implementation may enhance the interface by using TYPE(*), DIMENSION(..) choice buffer dummy arguments instead of using nonstandardized extensions such as !$PRAGMA IGNORE_TKR or a set of overloaded functions as described by M. Hennecke in [33], if the compiler supports this Fortran 2018 language feature. See Section MPI for Different Fortran Standard Versions for further details.
