conda on apple silicon

[GijsVermarien]

          I see that codes like bhtree and hop failed to build- that’s really not good. Those are ‘core’ packages… can you find out why these failed to build?

Created a new post to keep things separated, this discussion wasn't really about MESA anymore.

Here are the error messages for bhtree and hop. It seems to be a problem that certain functions aren't loaded correctly ?

make bhtree.code.txt
make hop.code.txt

right - the problem is that you're compiling with clang rather than gcc. We don't support clang currently.

This issue has been automatically marked as stale because it has not had recent activity. It will be closed in 28 days if no further activity occurs. Thank you for your contributions.

Just to note: conda-forge uses clang and gfortran to build all its Mac packages. There are GCC Conda-packages for Mac, but conda-forge doesn't use them by default. So I guess I'll have to see whether it's easier to get conda-forge to build with a different C++ compiler or to get AMUSE and the community codes to build with clang...

I do seem to have managed to build an Intel Mac package for amuse-framework now (on my Linux laptop, they cross-compile!), and my next step is to try to figure out how to get it to do the same for Apple Silicon. If I can make that work, then you'll be able to conda install amuse there...

Maybe we can keep the issue open then to track the progress? I can't add a keep-open tag, so I thought I would close the issue manually before the stalebot would close it.

Yes, why not? I'm doing all platforms at the same time, so there may be some overlap with #984, but people specifically interested in Apple Silicon would then be able to follow here, and maybe we can do a bit of testing here once I've got something testable together.

Latest update: conda claims to have built some Apple Silicon packages for amuse-framework (on my Linux laptop!), but I have no idea if they actually work. I'm going to try to make a package for ph4 next (because I want to test the Sapporo packages), and then do bhtree, for which I should be able to make Apple Silicon packages as well.

At that point I would be looking for a volunteer to see if they can get it to run on actual Apple hardware. I'll keep you posted 😄.

Cool, happy to guinea pig any binaries as soon as you're ready!
