Error when build MATLAB

General Usage

Hello everyone,

I use MacBook Pro M1 Max with macOS 13.2.

When I try to add the package with MATLAB R2022b. I will get the error:

    Building MATLAB → `~/.julia/scratchspaces/44cfe95a-1eb2-52ea-b672-e2afdf69b78f/e263657fe013cb02450c5d4210d2c50a354a5e08/build.log`

Recently, I install the MATLAB R2022b native apple silicon version.
When I build MATLAB , the output is:

Is there any solution to fix this error?

Welcome.
This issue was recently discussed on the forum here: Using MATLAB Package with R2022b and R2021b downloaded

Have a look at the README on the Matlab.jl GitHub page. You may need to use version R2021, and a Julia installation, using Rosetta.

Hi,

Many thanks for your reply.

Yes, the problem is the arm64 architecture. It is annoying.

Finally, I run both MATLAB R2021b and Julia 1.8.3 via Rosetta on arch x86_64, and I succeed. There is no issue.

I wrote down the procedure on my blog.
