Hi,
just an FYI, building 3.0 (and later versions, I guess) on 32bit archs fails with:
[ 884s] /home/abuild/rpmbuild/BUILD/blender-3.0.0/source/blender/blenlib/intern/string_cursor_utf8.c: In function 'BLI_str_cursor_step_utf8':

I know, using Blender as 32bit build somewhat contradicts its purpose, and currently dependent packages like OpenShadingLanguage does fail as well:

Therefor, it’s probably time to give up on it (finally…).
