Apple Silicon support?

it took a few days for the compilation to complete with or without parallel compilation. MRCC source code contains RegAlloc benchmarks of compilers.

Ah... that might not be practical to install on a laptop then... Was hoping to install it on my laptop to run quick tests or smaller calculations so that I wouldn't have to wait in line on the HPC (which is actually slower than my laptop anyway). I can't afford to spend a few days to wait for it to compile.

Didn't it used to compile much faster? I once compiled MRCC on a linux workstation and I could have sworn it didn't take very long. Or is it the fact it's an ARM chip that slows the compilation down?

Intel compiler can do it faster. GCC can't. Or disable optimizations

The problem comes from optimizations with GCC for autogenerated code.

Hello, 

I'm in a similar predicament, trying to install MRCC to an arm64 mac. I have correctly compiled openblas with 64 bit support, and followed the installation instructions but when it gets to the end of the build it gives an error stating: "Undefined symbols for architecture arm64". Did you see this problem? If so, how did you fix it? 

Sincerely,
Ben Kincaid

Dear Ben,

What is the list of undefined symbols? I did not remember all applied patches, unfortunately.

Best regards,
Igor
