Mathematica arm64 version needed on M1 MacBook? about mathlink.jl HOT 8 CLOSED

Dear @JanLeppert, from the logs it looks like some of the Mathematica Files cannot be found.

If that is the case, first try following this troubleshoot
https://github.com/JuliaInterop/MathLink.jl?tab=readme-ov-file#installation-troubleshoot
to se if linking to them manually works.

from mathlink.jl.

Thanks for the suggestion @fremling,

but what is the correct file for the MathLink dynamic library on MacOS? I cannot find any of the suggested files from the Readme (libML64i4.so/ libML32i4.so on Linux or ml64i4.dll/ml32i4.dll/libML64.dll/ libML32.dll on Windows). I also followed the link from the example for the deps.jl file and found the similar path on my system:
/Applications/Mathematica.app/Contents/SystemFiles/Links/MathLink/DeveloperKit/MacOSX-x86-64/CompilerAdditions
In this path there is a file libMLi4.a and I tried to link to this file, but with no sucess.

from mathlink.jl.

I must admit Mac is not my specialty: @simonbyrne do you know how Mathematica is set up on a Mac?

from mathlink.jl.

What does

file /Applications/Mathematica.app/Contents/Frameworks/mathlink.framework/mathlink

give? On my machine, I get:

/Applications/Mathematica.app/Contents/Frameworks/mathlink.framework/mathlink: Mach-O universal binary with 2 architectures: [x86_64:Mach-O 64-bit dynamically linked shared library x86_64] [arm64]
/Applications/Mathematica.app/Contents/Frameworks/mathlink.framework/mathlink (for architecture x86_64):	Mach-O 64-bit dynamically linked shared library x86_64
/Applications/Mathematica.app/Contents/Frameworks/mathlink.framework/mathlink (for architecture arm64):	Mach-O 64-bit dynamically linked shared library arm64

from mathlink.jl.

I only get one line with the x86_64 version:

/Applications/Mathematica.app/Contents/Frameworks/mathlink.framework/mathlink: Mach-O 64-bit dynamically linked shared library x86_64

from mathlink.jl.

Can you download a newer version which supports ARM? If not, then you should be able to use it with the Julia x86 binaries.

from mathlink.jl.

Thanks @simonbyrne

I was able to update Mathematica to a newer version, which also supports ARM. With this I was able to use MathLink.

So the answer to my question would be, that you need the ARM version of Mathematica for a Mac with M1 processor.

from mathlink.jl.

You need the platform to be the same for both Julia and Mathematica (you should be able to in both x86 under Rosetta)
