Arch Linux User Repository

Data and config files previously stored in ~/.local/share/cemu are now searched in ~/.config/Cemu, ~/.local/share/Cemu and ~/.cache/Cemu.

Sorry but I will do none of that :p

The added dependencies are only needed when you build the libs manually with vcpkg, which I will not enable.

And it's up to you to tweak the compiler flags in makepkg.conf, not to each PKGBUILD.

The only good solution is to create a compatibility package fmt9, and this PKGBUILD will build again without modification.

(@abouvier we can use these edits to make Cemu build-able again until the libfmt issue gets worked out)

Some the depends/makedepends I included were missing and are actually listed as necessary dependencies upstream:

https://github.com/cemu-project/Cemu/blob/main/BUILD.md#for-arch-and-derivatives

depends=(
    'discord-rpc'
    'freeglut'
    'gcc-libs'
    'glibc'
    'hicolor-icon-theme'
    'libc++abi'
    'libpulse'
    'libx11'
    'pugixml'
    'sdl2'
    'systemd'
    'wxwidgets-gtk3>=3.2'
    'zlib'
)
makedepends=(
    'boost'
    'clang'
    'cmake>=3.21.1'
    'cubeb'
    'curl'
#   'fmt>=9.1'
    'git'
    'glib2'
    'glm'
    'glslang'
    'glu'
    'gtk3'
    'libgcrypt'
    'libgl'
    'libpng'
    'libsecret'

    'wayland'
    'wayland-protocols'
    'zarchive>=0.1.2'
    'zip'
    'zstd'
)

Need to pull all the submodules or vcpkg will get mad (you might be able to refactor it to include everything besides fmt? Probably not)

prepare() {
    cd $_pkgname
    git config submodule.dependencies/imgui.url ../imgui
    git -c protocol.file.allow=always submodule update --init --recursive
    rm -r bin/shaderCache
    sed -i '/CMAKE_INTERPROCEDURAL_OPTIMIZATION/d' CMakeLists.txt
    sed -i '/discord-rpc/d' CMakeLists.txt
    sed -i '/FMT_HEADER_ONLY/d' src/Common/precompiled.h
    sed -i 's/glm::glm/glm/' src/{Common,input}/CMakeLists.txt
}

The if-check to both start using vcpkg and better account for using clang+LLVM if users have set clang in makepkg.conf

    if [ "${CC} = "gcc" ] || [ "${CC} = "/usr/bin/gcc" ]; then
        cmake -S $_pkgname -B build \
            -DCMAKE_C_COMPILER="${CC}" \
            -DCMAKE_CXX_COMPILER="/usr/bin/g++" \
            -DCMAKE_BUILD_TYPE=Release \

The fmt build error might be related to the update to fmt on the arch repos from yesterday. I can't update my packages because this and two other emulators require the previous version, that might be why but I'm not sure.

There appears to be a build error connected to CubebInputAPI.cpp that might be connected to a core.h header error with the fmt package:

@modnoob Just rebuild. This "soname" dependency is automatically determined during the build. There's no change to the PKGBUILD file itself required.

The build fails with: :: unable to satisfy dependency 'libboost_filesystem.so=1.80.0-64' required by cemu-git :: unable to satisfy dependency 'libboost_program_options.so=1.80.0-64' required by cemu-git Time to change some of the dependencys I would guess.

Oops, I deleted and recloned the cemu repo and now I get the same result as you. The local config of the old repo was probably messed up.

I added --abbrev for nothing it seems :$

Sorry but no, I tested on many machines with different distro, same result. None of them have anything special, very vanilla.

git describe --long --tags always result in v2.0-22-0-g058d11b.

In any case, adding --abbrev solve the issue.

I get the same pkgver value (i.e. 2.0.22.r0.g058d11b4) with or without --abbrev=8. There is definitely something weird with your git installation :p
