Confirmed. Fails.
(Funny I did not test that before)
This is probably not due to fpcupdeluxe, though, but looks like an error in the make script.
Tested mac mini M4 fully up-to-date.
I think there are not many people who tried this.....(Just us two, maybe?)
Although sfpux80 (soft floats) is not really used on x86_64-win64 it needs to be compiled in.
What is strange, though: Error: /Users/jiten/lazarus4/fpc/bin/aarch64-darwin/ppca64 ???
It should be already a ppcrossXXX at that point? The aarch64 compiler is never to compile sfpux80 because it is not part of aarch64 eco system. But the cross compiler should.
