The PKGBUILD for this package is hosted here (contributions are welcome!): https://gitlab.com/dpeukert/pkgbuilds/tree/main/dolphin-emu-git

@xiota what should i do then? i even deleted the emulator and tried to do a clean build (again)

Clean chroot. Builds fine after installing fmt9. However, I'm wondering why not remove fmt9 and use build flag -DUSE_SYSTEM_FMT=OFF?

@Tortillas-IT: Can you post your build output?

i still can't compile the new updated package, even with a clean build

Hi using fmt0.9 from AUR solved all provlem. It seems that dolphin is still not ready for the new fmt yet.

Won't compile since latest commit (FAILED: Source/Core/Common/CMakeFiles/common.dir/Version.cpp.o)

According to FS#78628, the following prevent the segfault in extra/dolphin-emu:

• Adding !lto to options.
• Using clang instead of gcc.

dolphin-emu-git is failing to build in clean chroot. Looks like fmt issues again.
