Kristoffer, Thank you so much for helping.
I don't really know what's happening. I've run the intel script (mklvars.sh) to set up my environment variables correctly (good to know the tip !). I still get the same error message in my Juno IDE (mac os) : Intel MKL FATAL ERROR: Cannot load libmkl_intel_thread.dylib. But the whole thing is working in the Julia console (for both 3.11 and 4.0) : see image So apparently the pb is sitting from the Juno IDE side and note the Julia side. I'll report that on the Juno discussion forum. Thanks again, Lionel PS : I'll try to build a MKL version of Julia soon. <https://lh3.googleusercontent.com/-kDBeZbJaxt0/ViOYe55az1I/AAAAAAAAEew/PkExl_P1w6U/s1600/Julia%2BMKL%2Bccall.png>
