My upstream PR got merged a few minutes ago. Building works now again without needing patches

It compiles fine here after applying this patch: https://github.com/RPCS3/rpcs3/commit/8636a5c80c3966b13c8a05e27051855400a33ebb.patch

It also compiles with llvm 21 from testing and you can use ffmpeg system libraries: -DUSE_SYSTEM_FFMPEG=ON \

I found this issue in Github (https://github.com/rpcs3/rpcs3/issues/17570), so I created a patch to fix this issue when building with Qt 6.10.

Good catch, fixed @HurricanePootis

This is caused by the recent update of GCC from version 14 to 15. I have just fixed it over at rpcs3 by including a simple patch.

Got this at about 88% of the way. Pretty frustrating!

Thanks for the previous fix! But it's broken again...

You should add vulkan-headers as a makedepends, see here: https://github.com/RPCS3/rpcs3/issues/17002

Woops, forgot to sync up, should be fixed now @Neros
