Other information

I worked with @theurich to get the macOS + LLVM Flang build for ESMF working (see esmf-org/esmf#558). This update is now in ESMF 9.0.0b17.

Currently, spack-stack is on b11, I think? So there are probably other updates that come with this. And to this end, I might ask @theurich to chime in.

For example, I know I'll probably need to update the esmf/package.py because of esmf-org/esmf#557 (which added nagclang which is not yet a valid ESMF_COMPILER in the spack package). Of course, this doesn't go to mainline spack until 9.0.0 is official.

But there are also things like esmf-org/esmf#567 which I think moved ESMF_COMPILER=intel to now default to the LLVM compilers instead of the classic ones. I think spack should be fine here. And @theurich did some YAML like fixes in esmf-org/esmf#574 that hopefully should take care of any issues with #2027

However, the biggest update/change might be esmf-org/esmf#549 . That was brought about by @AlexanderRichert-NOAA in spack/spack-packages#5045 . This adds the new ESMFConfig.cmake and ESMFConfigVersion.cmake files on install.

Now, spack should do its thing right there. That's fine. But, it's our user code that might need testing. GPT helped with some thoughts I have for GEOS at GEOS-ESM/ESMA_cmake#561 and some PRs off that.

NOTE: Even with b17, I still might need help from ESMF (aka a patch on our end). I made an issue (esmf-org/esmf#579) and PR (esmf-org/esmf#580) for some weirdness I saw with NAG.

@mathomp4 thanks for starting the conversation. I agree that we want to update ESMF in spack-stack very soon. However, let's wait just a little longer and not jump on 9.0.0b17 quite yet.

There is PR (esmf-org/esmf#547) that is still under review right now, and that is what I really want asap for the NRL work. My hope is to have that finalized this week and available in a new beta tag by early next week.

The other thing I am hoping to look into asap are the issue (esmf-org/esmf#579) and PR (esmf-org/esmf#580) that you mention. Would be nice to have that also settled in the next beta before we update spack-stack.

@theurich Okay. I've changed it to be 9.0.0bXX for now. Maybe even 9.0.0 flat. :)

Thanks. It will definitely be a beta so we can start adjusting to changes before the official 9.0.0.
