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.

To clarify, the compile flags aren't being modified;

it checks if those valuea are already defined and decides whether to build with LLVM or not, which upstream only does for clang.

The users themselves wouldn't have to modify the PKBUILD at all.

That aside, if you're sure about a fmt9 package, sure, but it'll only make more work for you.

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'
    'libzip'

    'openssl'
    'rapidjson'

    '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}" \

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.
