Hi, My name is Marina Marjanovic and I am currently working on my master degree and I need gcc7 to make it work with MESH( https://wiki.usask.ca/pages/viewpage.action?pageId=1935648493 ). But I had a MacBook air 2015 and everything was working fine, so I got a new MacBook pro M1 and nothing is working anymore. I have some issues with gcc on a new MacBook Pro, ship M1 pro. I need gcc7, but I have an error message saying : gcc@7: The x86_64 architecture is required for this software. And the new version of gcc11, is not working with MESH…. I am wondering what can I do to make it work? Can you help me? Thank you for your time, Have a good day Marina
