It shouldn't. This package builds from source and has checksums.

@kescherAUR Was this package affected by Cemu's recent security issues?

@kescherAUR

Since upstream recommends a clang+llvm build, can we use LLD + ThinLTO to speed up compile times? Edit:

After going through this PKGBUILD, I recommend the following:

  1. Make license spdx compliant with MPL-2.0
  2. Add a bunch of missing dependencies: speexdsp, glslang, wxwidgets-common, curl, glib2, libgcc, zlib, libstdc++, gtk3, libx11, openssl, zstd, and hicolor-icon-theme
  3. Remove unnecessary depedencies: wayland-protocols, llvm-libs
  4. Use LLD + Clang for ThinLTO fast compiles
  5. Install desktop file as its original way as to not break icons on wayland.

Also, please add your maintainer information to the top of the PKGBUILD.

@TipsyTheCat I had already tried that but without the --rebuild option. Adding it made Cemu work again though, thank you!

TipsyTheCat commented on 2025-10-18 02:10 (UTC)

@kihra1 @darxoon run paru -S --rebuild cemu to rebuild cemu after you upgrade your system. you can probably replace paru with your aur pacman wrapper of choice

darxoon commented on 2025-10-17 22:35 (UTC)

After upgrading my system, now I always get this error when I try to run Cemu:

cemu: error while loading shared libraries: libglslang.so.15: cannot open shared object file: No such file or directory

HurricanePootis commented on 2025-10-13 20:18 (UTC)

@kihra1,

For AUR packages, you're supposed to rebuild them yourself.

Kihra1 commented on 2025-10-13 06:35 (UTC)

$ cemu cemu: error while loading shared libraries: libglslang.so.15: cannot open shared object file: No such file or directory

I think libglslang has a new update (1:1.4.328.1-1) and cemu needs to be rebuilt against it.

Downgrading libglslang to 1:1.4.321.0-1 works.
