It builds with the new version of Xcode/command line tools, right?   
Thanks again.  

> We do not yet know if CCL will run on the M1 Macs under Rosetta. My M1 mini is scheduled to arrive next week and I will test CCL as soon as it arrives. (If it doesn’t work, I will try to fix it.)   
> A couple of us at Clozure have had access to Apple’’s Developer Transition Kit which is a prototype Apple silicon Mac. However, as a prototype, it has hardware limitations which prevent CCL from running under Rosetta. Apple claims that those limitations do not exist in the shipping systems. But, of course, we’ll find out once I get my machine.  
> One last note …  
> If you want to rebuild CCL on Big Sur, you’ll need to ensure that your copy includes the commit [553c0f2](https://github.com/Clozure/ccl/commit/553c0f25f38b2b0d5922ca7b4f62f09eb85ace1c) which fixes a bug that prevents the kernel from loading any images.
