incorrect AMD math library link order

[Wei-Keng Liao]

Hi, Max

Could you modify build_pnetcdf.txt to compile a simple F90 program
(example programs can be found from MPICH repo in
https://urldefense.us/v3/__https://github.com/pmodels/mpich/tree/main/examples__;!!G_uCfscf7eWS!ZybsrnnDV1S14dcgjy_1LvdWBCaETPr4Q1Otck0NxOd88RAKBM7zkJ83Q92kLQB4fmAjZaQ61tIuZvbki1_Pap693pJ7Luw$ )

This is to see if the environment variables set in build_pnetcdf.txt
also work without PnetCDF? For example, run this command:
    mpifort pi3f90.f90

If that works, could you try this configure command, without running
build_pnetcdf.txt? i.e. no environment variables are set.
   ./configure --with-mpi=$HOME/AOCC/opt/amd/ompi/5.0.2

If the above failed, please send me file config.log.

Hi Wei-keng,

...Same problem.  I am attaching my build procedure.

I even tried hacking the Makefile and libtool, to no effect.

Best regards,

Max

Hi, Max

Could you give the release candidate 1.13.0.rc1 a try?
The configure utility files have been updated since 1.12.3,
which may fix the problem.

Hello Wei-Keng,

Building PnetCDF 1.12.3 with AOCC compilers, I found that
libamdlm is linked after libm ('-lm -lamdlibm') instead of
before as it should be; so far I have not found any way to
change this.  If I set LIBS='-lamdlibm' and configure, both
FCLIBS and FLIBS in the resulting Makefile are assigned

-L/home/maxd/AOCC/opt/amd/ompi/openmpi-5.0.2_aocc-4.2.0/lib -L/usr/lib/gcc/x86_64-linux-gnu/10 -L/lib/x86_64-linux-gnu -L/lib/../lib64 -L/usr/lib/x86_64-linux-gnu -L/home/maxd/AOCC/opt/amd/aocc/4.2.0/bin/../lib -L/lib -L/usr/lib -L/home/maxd/AOCC/opt/amd/aocl/4.2.0/aocc/lib -L/home/maxd/AOCC/opt/amd/aocc/4.2.0/lib -L/home/maxd/AOCC/opt/amd/aocc/4.2.0/lib32 -L. -lamdlibm -lmpi_usempif08 -lmpi_usempi_ignore_tkr -lmpi_mpifh -lmpi -lflangmain -lflang -lflangrti -lpgmath -lquadmath -lompstub -lm -lrt -lpthread

which is promising.  However, in the link it's wrong:

Any suggestion for how to remedy this?
