issue with apple silicon precompiled binaries

jechristian

Hi there,
I'm new to ISSM and attempting to start out using the precompiled binaries for Apple Silicon. I'm running Matlab R2023a and have a Mac with an M2 chip.

I'm getting the following error

ISSM not correctly installed. "IssmConfig_matlab" not found

when I run issmversion, and when I run e.g. 'md=model', a string of errors that traces to IssmConfig, where again 'IssmConfig_matlab' is not found. I can see there is an executable IssmConfig_matlab.mexmaca64 in ISSM's lib directory, but only IssmConfig.m in bin.

Incidentally, I also tried the binary for Mac Intel, and I don't run into this error in that case. Tutorials fail later on (presumably from running the intel version on apple silicon) but evidently finding IssmConfig_matlab isn't the issue in that case, which made me think the above problem with the Silicon binaries wasn't just an issue with paths or something.

thanks for any help here.

Hello John,

t depends on the version of Matlab that you have. Older version expect mexmaci64 whereas newer versions of Matlab will execute mexmaca. If you have an "old" version of Matlab (I think before 2023b, but I am not sure), then download the intel binaries. Ideally, you may want to update MATLAB to the newest version and use the Apple silicon
binaries to make sure that it runs natively on your machine.

Hi Mathieu,
Many thanks for your fast response. This makes sense.
It turns out my institution by default installs the intel verion of matlab, which runs on silicon thanks to rosetta - so that different mex format explains it (but I'm asking for silicon version just in case). But for now, the intel binaries seem to be working for me (once I corrected a host issue).
Thanks again!
