The first problem I see in the log is several occurrences of:

:info:configure usage: mktemp [-d] [-q] [-t prefix] [-u] template ...
:info:configure        mktemp [-d] [-q] [-u] -t prefix

I'm not sure if the failure to create the temporary directories might lead to the errors you saw later. I filed a bug report:

​https://github.com/xmake-io/xmake/issues/5464

Try the fix I proposed there and see if that changes anything.

Then I see:

:info:configure build/macosx/power macintosh/release/xmake.config.h is generated!

So it has created a directory containing a space (power macintosh) and probably isn't quoting all references to that variable, leading to the wrong path being used:

powerpc-apple-darwin10-gcc-4.2.1: macintosh/release/core/src/lua/lua/lcode.c.o: No such file or directory

Figure out wherever that directory is being created (probably from the output of uname) and fix it so it doesn't have a space in the name, or else quote all uses of the variable.

Finally:

cc1: error: -Werror=nullability-completeness: No option -Wnullability-completeness
cc1: error: -Werror=parentheses-equality: No option -Wparentheses-equality

I don't see where -Werror=nullability-completeness or -Werror=parentheses-equality are being added. I see where -Wno-error=nullability-completeness and -Wno-error=parentheses-equality are being added:

​https://github.com/xmake-io/xmake/blob/216192e56b4fcfa664a7efe59c5b873a2f78adbb/core/xmake.sh#L15-L18

Maybe the compiler mistakenly printed -Werror in the error message when it meant -Wno-error. Ideally upstream should test whether the compiler supports a flag before adding it. If they won't do that here, this can be patched out of the build system for old compilers.

They've fixed this bug:
