FMS build fails on fortran compiling command steps

[ziglaser]

I'm attempting to build MOM6 using the fork intended to work with regional-mom6, using the exact procedure outlined in the GitHub. During the ninja build in the 'shared' folder, I get the following error:

ninja: error: 'src/FMS/affinity/fms_affinity.F90', needed by 'fms_affinity_mod.mod', missing and no known rule to make it

Which corresponds to the following line in the ninja build

'build fms_affinity.o fms_affinity_mod.mod : fc ${srcdir}/FMS/affinity/fms_affinity.F90 | ${srcdir}/FMS/fms/fms.F90 ${srcdir}/FMS/mpp/mpp.F90 || fms.o mpp.o'

However, the file src/FMS/affinity/fms_affinity.F90 does exist in src. If I remove that line, it fails on the following fc build line. Since it makes it through the first 12 lines of cc commands, I assume something is going wrong with the fc process. Happy to provide any more detail if it would be helpful, I'm curious if the clean build works from start to finish for anyone else.

Sorry, this is very late to be getting back to you, but it sounds more like your srcdir is configured incorrectly, and so the build system just can't find the source files.
