Arch Linux User Repository

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

@scatherinch you just apply the changes in question to the PKGBUILD file from the repo, then run makepkg -si or whatever the AUR helper you're using expects.

EDIT: never mind, I see it is solved for you

@Peter0x44 I'm still kind of new to Arch. One thing I haven't scratched yet is how to build or modify packages in the way you described. However, maybe you wouldn't mind giving me a quick rundown or pointing me to a resource where I could learn to do this?

I would really like to learn and fix this issue!

EDIT: I figured it out. Seems to have solved it for now, can confirm

@scatherinch My suggestion is (as others have mentioned) that you remove "libfmt.so" from the depends, and build dolphin-emu-git using a static fmt that dolphin provides

Here's the relevant patch to the PKGBUILD

Once this gets resolved (hopefully) this workaround won't be necessary

Then, you should be able to update, without any conflicts on libfmt.so.9

I already had this installed beforehand, but trying to -Syu returns an error claiming that updating will break this. I would like to do the update, but I don't want to lose dolphin because I think removing it to update will most assuredly prevent me from installing again from what I've been reading.

error: failed to prepare transaction (could not satisfy dependencies) :: installing fmt (10.0.0-1) breaks dependency 'libfmt.so=9-64' required by dolphin-emu-git

Therefore, I have not been able to update my system for a few days. Is there a way around this or should I just wait for this to become compatible with the new version of fmt?

Clean chroot. Successfully built after adding -DUSE_SYSTEM_FMT=OFF. No other changes to the PKGBUILD.

One way around some of the system lib issues would be to use internal like so:

    -DUSE_SYSTEM_LIBS=ON \
    -DUSE_SYSTEM_FMT=OFF \
    -DUSE_SYSTEM_LIBMGBA=OFF \
    -DUSE_SYSTEM_MINIZIP=OFF \
    -DUSE_SYSTEM_SPNG=OFF \
    -DUSE_SYSTEM_ZLIB=OFF \

Just a thought.

You can depend on fmt9 if you want ;)

while upstream dolphin doesn't work with vulkan since last update

soo… I can't upgrade until dolphin becomes compatible with fmt10?
