Problem make installing the package

[RunningXinLiu]

Hi Haipeng,

I am installing this package on my macbook pro M1. I have openmpi installed:

 mpif90 --version
GNU Fortran (Homebrew GCC 11.2.0_3) 11.2.0

However, when I run make in the fd2dmpi folder I got the following error indicating grammar error. Could this be a problem with my mpi library？

❯ make

BTW, I dont have any problem make install this package on my remote sever, which uses the same mpi distribution as indicated in your tutorial.

mpif90 --version

Thank you for your interest. This code has complied successfully on the Intel and AMD CPUs. On the Macbook pro with the M1, I have also encountered your problem. It seems that OpenMPI or other MPI does not work very well with the M1 chip so far (just a guess, and I'm not so sure).

Please be careful with the MPI problems and the M1 chip. I have burned out an M1 chip and get my motherboard repaired...

Thank you Haipeng. This M1 chip has caused me a lot of headaches. I haven't managed to run specfem package with it probably due to the same cause. Also I the fortran language server fortls are not supported by M1... I should have just sticked to ubuntu...

Best,
Xin

You're definitely welcome. The M1 chip also troubles me a lot. I now use it only as a code editing tool and run the code on remote servers or HPC platforms.

Best,

I am trying to work remotely with vs code. But the server I am using does not have an internet connection. It was painstaking to download modules, packages locally and scp to the server and manually install them.

[Haipeng-ustc]

I'm basically in the same working mode using VS code, but our computational server can access the internal internet, which makes it easier to download some packages.

Hi, I'm experiencing the same issues as above but on a ubuntu machine with a intel CPU. What am I doing wrong here?

[Haipeng-ustc]

Hi, could you please provide more details about your problem? I would like to help to resolve this issue if I can.

[Whitt1985]

So I've followed the instructions on the front page of GitHub and I get the exact same errors as the user above when the make file gets to the io file.

How can I validate my openmpi build is correct?

[Haipeng-ustc]

Hi, sorry for the late response. I was busy with my finals these days. I noticed that there are some possible solutions to this problem from https://stackoverflow.com/questions/69686755/fortran-error-type-mismatch-between-actual-argument-at-1-and-actual-argument. I excerpt two approaches here that seem good to me.

1. Tells FORTRAN to ignore these concerns with option -fallow-argument-mismatch.
2. Use modern FORTRAN interface (use mpi instead of include mpif.h).

The author explains that "the cause is a decision from gcc developpers on what should be «good interfaces» see here. "

Hope one of these methods works for you.

Best,

Haipeng

Specfem is running fine in my M1-max chip. BTW last night, specfem-2d release a new version.
