I also get compile errors using gcc at the moment.
I use gcc in Msys2 - Windows 10. (gcc version 11.2.0)

Compiling without the -j switch seems to work.
I guess there has been a change with gcc?

SOLVED! Thank you.

Model3GraphicsState.h should only be included if the DEBUG option is enabled, so I'm not sure why it's being compiled at all.

In any case, I've fixed the cause of the build error in the latest SVN.

R869/R870 breaks compilation on linux test systems (R868 compiles okay):

The error appears to be "cannot create obj/PPCDisasm.d: Directory nonexistent"... I'm confused, is it failing to create the obj folder for some reason?

It seemed that way. That said, when I tried compiling again, it succeeded(!)

My only guess is that supermodel can compile so fast that sometimes certain tasks such as the one in the log above complete before they should (a race condition of sorts). This project compiles in less than 30 seconds on this system (Intel i7-10870H), with -j9 specified. In any event, probably not something worth worrying too much about.
