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

It's missing a dependency on libsm.

There is also some problems with glslang that can solved with the following patch:

No idea why, but recloning the PKGBUILD repository for the 4th time worked. No idea what the deal was before, but it's built successfully now. My apologies, then!

queenbiscuit311 commented on 2023-08-03 18:29 (UTC)

I've downloaded the pkgbuild fresh multiple times, but I'll try again.

abouvier commented on 2023-08-03 18:19 (UTC)

You are not building the latest version of the PKGBUILD.

I've found myself unable to build this package ever since the fmt 9/10 incident. Every time I try to compile, I get met with this error:

I've tried reinstalling and updating both fmt and fmt9, but nothing's worked.

Building with Clang and -stdlib=libc++ doesn't seem to actually use LLVM's libc++?

Using ldd on the resulting binary shows it links against gcc's: => /usr/lib/ (0x00007efcc2c00000) => /usr/lib/ (0x00007efcc527c000)

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.

abouvier commented on 2023-07-30 07:34 (UTC)

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:

#   'fmt>=9.1'

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 '/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

        cmake -S $_pkgname -B build \

        cmake --build build
    elif [ "${CC} = "clang" ] || [ "${CC} = "/usr/bin/clang" ]; then
