[MITgcm-support] problem compiling MITgcm with openmpi on mac big surr

[Mainak Mondal]

Hi,

I recently tried installing MITgcm on macbook pro M1 with 8 core.

I tried the followings:

I installed openmpi, netcdf using Homebrew.

%%%%%%%%%%%%%%%%%%%%%%
checking for packages installed
%%%%%%%%%%%%%%%%%%%%%
pinta at Mainaks-MBP ~ % which gcc
/usr/bin/gcc
pinta at Mainaks-MBP ~ % which gfortran
/opt/homebrew/bin/gfortran
pinta at Mainaks-MBP ~ % which mpif90
/opt/homebrew/bin/mpif90
pinta at Mainaks-MBP ~ % which ncdump
/opt/homebrew/bin/ncdump
%%%%%%%%%%%%%%%%%%%%

I downloaded the latest MITgcm

I tried to compile MITgcm/verification/tutorial_plume_on_slope/ using 8
cores.

%%%%%%%%%%%%%%%%%%%%
initially while in the build directory, I ran
pinta at Mainaks-MBP build % ../../../tools/genmake2 -mods=../code  -mpi

It shows:
The platform appears to be:  darwin_arm64
Error: can't read OPTFILE="../../../tools/build_options/darwin_arm64_mpif77"

Then I tried with the optfile
../../../tools/genmake2 -mods=../code
--optfile=../../../tools/build_options/darwin_amd64_gfortran -mpi

I changed the followings:
FC=mpif90
commented out
#FFLAGS="$FFLAGS -fconvert=big-endian"

%%%%%%%%%%%%%%%%%%%%%%%%%%%
while make depend , I got lots of warning messeges like:

./mpif.h:37:24: warning: missing terminating ' character
[-Winvalid-pp-token]
! That being said, OMPI's "mpifort" wrapper compiler should

while doing make

Error: Type mismatch between actual argument at (1) and actual argument at
(2) (INTEGER(4)/REAL(8)).
cumulsum_z_tile.for:1193:27:

I would really appreciate it if anyone can help me.
