Squeak 6502 images on Mac Catalina

Hi,

With Apple dropping support for 32-bit apps in Catalina, what is the
recommended way to work with Squeak 6502 images? The mac builds in
files.squeak.org/3.8 will not work anymore.

Has anyone built a 64bit version of the trunk VM that works on Catalina?

I suppose one can install Parallels or VirtualBox to continue using
older apps, but why use a sledgehammer to shell a peanut?

Thanks .. Subbu

The interpreter VM is a 64 bit app running 32 bit images, so no
issues with 32-bit support. However, I expect that there will be
problems compiling on the newer llvm toolset, so I don't know if
a freshly compiled VM will work on Catalina.

The SqueakJS VM is a good choice in many cases, and it does run
6502 images.

The current workaround is to run it in Ubuntu virtual PC on a Mac, but
it shouldn't be this hard.

I wonder how other students are coping with this situation.

Yes, but it is not a good option for beginners. Running it off the net
makes it sluggish and running it off a local server is not trivial (due
to CORS restrictions).

No, there is no pre-built VM available. There have been many changes
to the Quartz display (though X11 should still work). And OS X is now
using llvm compiler tools, which will probably require some development
work. No one is working on this as far as I know.

This is probably the best approach for now.

Thank you for the confirmation. I suppose SqueakJS holds more promise.
But that discussion is more suited to vm-dev mailing list.
