Interesting I'll take a look.
FWIW, for cross compiling Qt 5, I set it up by setting a bunch of
QMAKE_MAC_* variables to configure - but the basic gist of it is that you
have e.g. "x86_64-apple-darwin-clang++" (or -g++ which does the same)
which you can use basically like a regular target-triple-prefixed cross
gcc.
Do you by any chance have a working icecream/iceccd compiler package? I have
200 job slots for Linux, for Windows, and for FreeBSD, but only 12 for Mac
(one 6-core Mac Mini).
Sorry, no, I haven't used such setups at all.
Cross compiling still requires a SDK root from Xcode (which afaik isn't
redistributable), so my setup requires copying and stripping it down from
a real Xcode install. (There are repos on github that provide the bare
sysroots though, although I'm wouldn't bet on whether one can consider
them redistributable like that - I haven't integrated scripts for making
use of that.)
Well, I have a Mac Mini, so I have the sysroot. I can package it like I did
for FreeBSD. But I'm more interested in the icecream setup, which doesn't
require sysroot since everything is preprocessed on the host.

These days (last 6-12 months roughly) lld has become pretty mature for
targeting macOS for x86_64 and aarch64 (AFAIK current release versions of
Chrome are built with it), but I haven't tried hooking it up in my setups.
I think Chrome uses the standard Clang too, not Apple's fork.
Yes, I'd think so too.
