Current State Of Linux Builds

[Crementif]

Linux builds of Cemu are not recommended yet for beginners, since currently it lacks a few things:

• There's only prebuilt binaries for ubuntu 20.04, which means that for other distros (or versions) you'll have to compile it yourself.
  • In the future the plan is to also distribute appimages and/or flatpak releases using the CI.
• Cemu currently requires all files to be placed in a case-insensitive filesystem
• Cemu utilizes GTK3 using wxWidgets and xlib for it's Linux port currently. Wayland support should work but other environments aren't tested.

You can use this issue to share your experiences, issues or build tips!

One thing I notice, being on Gentoo running OpenRC, is that the binary, and compilation seem to hard require systemd. Not sure if there's a CMAKE flag included to disable systemd support or not. To be clear, not saying you need to support openrc at all, but maybe a compile flag to disable the systemd stuff would be nice. (I'm not very experienced with CMAKE so maybe there is a way I'm just not aware of).

It is unusual that the project requires the entire Vulkan SDK, as opposed to just the headers. Any comment on this?

[lunaneff]

For Flatpak, would you mind if I tried to make a package? I can't guarantee anything, but I could see if I can get something working later today

Also-- Is there a reason vcpkg is used on linux? vcpkg is, no matter what microsoft says, designed for windows, and it doesn't make a ton of sense to have to compile all of the dependencies when they are already available in the various package managers.

Sure, although we'd like to have an official flatpak package. I'm not sure if/how other emulators do that with their continuous builds, but maybe worrying about that is a later step and you should see if it requires some source code changes first.

I ran into compilation issues on Windows when trying to compile with headers only after we switched from VS solution to cmake. I forgot where exactly the dependency comes from but it was meant as a quick and dirty fix to just add the whole thing. In general there are a lot of dependencies that could probably be optimized out.

I like it because it generally seems to be the most hassle free across platforms. But yes, ideally we would conditionally use system libraries if present. Will look into this

I sadly couldn't get this to compile on Arch so I'm sharing my steps in case somebody else wants to give it a whirl:

1. Install dependencies

sudo pacman -S --needed gtk3 libsecret libgcrypt systemd-libs freeglut nasm

2. I had clang-14.0.6-2 installed on my system so I decided to downgrade everything to v12 just in case

yay -S downgrade
sudo downgrade clang llvm llvm-libs

3. Install VulkanSDK

cd ~
mkdir vulkan
cd vulkan
curl https://sdk.lunarg.com/sdk/download/1.3.224.0/linux/vulkansdk-linux-x86_64-1.3.224.0.tar.gz | tar xz
cd 1.3.224.0
source setup-env.sh

4. Get Cemu

cd ~
git clone --recursive https://github.com/cemu-project/Cemu
cd Cemu
mkdir build
cd build
cmake .. -DCMAKE_BUILD_TYPE=release -DCMAKE_C_COMPILER=/usr/bin/clang-12 -DCMAKE_CXX_COMPILER=/usr/bin/clang++-12 -G Ninja -DCMAKE_MAKE_PROGRAM=/usr/bin/ninja

5. Compile

clang-12: error: linker command failed with exit code 1 (use -v to see invocation)

[lunaneff]

Sure, although we'd like to have an official flatpak package.

Even if I haven't been involved in Cemu before, if you approve of it, wouldn't that make it official? Also, when it's ready for publishing I could ask to have you added as collaborators on the repo, so you could make changes as well

I'm not sure if/how other emulators do that with their continuous builds

Flatpaks are almost always compiled from source on Flathub's servers if the code is available. The only exception I can think of is osu, where it's because a small bit of code that's required for online functionality is proprietary to avoid cheaters.

you should see if it requires some source code changes first.

A .desktop file (for app menus) and a metadata file (for app stores) will be required. These can also be added in the flatpak instead of upstream, but upstreaming is preferred since these aren't Flatpak-specific and are also useful for other distribution methods. You can find info about these at these links:

• https://standards.freedesktop.org/desktop-entry-spec/desktop-entry-spec-latest.html
• https://www.freedesktop.org/software/appstream/docs/index.html

fatal error: 'SPIRV/Logger.h' file not found

@Anuskuss looks like you're missing these headers. On Ubuntu, you can get them from this package: glslang-dev. I am unsure about Arch, but I would make sure the -devel packages are getting installed if they exist, so you have the required development packages, not the release packages.

Commenting include lines is probably not going to net any positive results. I would focus on fixing missing dependencies or why functions are missing. Most likely the required development files are not installed. (I'm not sure if this package was overlooked on the dependencies, but Exzap did say the linux build needs work.

FYI it looks like pacman has an apt-file search alternative, pacman -F. This allows searching for packages that provide a specific file, including searching the relative path, like SPIRV/Logger.h.

[Anuskuss]

@Drakonas I appreciate you trying to help but I'm not really looking for support. I'll just wait for the AUR/AppImage/Flatpak.

looks like you're missing these headers.

Oh no, they are there. Don't know why CMake can't find them though.

$ locate SPIRV/Logger.h
/home/user/vulkan/1.3.224.0/source/glslang/SPIRV/Logger.h
/home/user/vulkan/1.3.224.0/x86_64/include/glslang/SPIRV/Logger.h
/usr/include/glslang/SPIRV/Logger.h

[Anuskuss]

I think most people have figured this out already but the precompiled binary is way easier to get going. Just need to install libselinux and symlink the missing libraries:

yay -S libselinux
sudo ln -s /usr/lib/libffi.so.8 /usr/lib/libffi.so.7
sudo ln -s /usr/lib/libpcre.so.1 /usr/lib/libpcre.so.3
sudo ln -s /usr/lib/libsepol.so.2 /usr/lib/libsepol.so.1

Unfortunately audio doesn't seem to work and it can't read WUD/WUX but it's a start. Will investigate more tomorrow. Although I did try manually installing the packages (from Debian) and that still didn't work...

[amayra]

i hope we see AUR support soon

[tinyzimmer]

@Anuskuss I'm going through almost identical steps as you and getting the same issues more or less. I am, however, trying to avoid modifying source. One thing I'm curious about, are you sure downgrade is actually downgrading to clang-12? I'm suspecting issues with clang-14.

[aquova]

I attempting to compile on Arch Linux as well, although still on clang 14, and I saw these same issues. For others looking to try, it should be noted that I also needed the vulkan-headers package installed and needed to set up the environment variable via export VULKAN_SDK=/usr in order to get that far.

[tinyzimmer]

@aquova The alternative to that (which would also be more cross-platform if to be added to documentation) is just downloading the headers:

sudo mkdir -p /opt/vulkansdk
curl -JLO https://sdk.lunarg.com/sdk/download/1.3.224.0/linux/vulkansdk-linux-x86_64-1.3.224.0.tar.gz
sudo tar -C /opt/vulkansdk/ -xf vulkansdk-linux-x86_64-1.3.224.0.tar.gz
rm vulkansdk-linux-x86_64-1.3.224.0.tar.gz

Then you can set VULKAN_SDK to /opt/vulkansdk/1.3.224.0/x86_64/.

However, it is definitely easier to use pacman on Arch.

[Lithium64]

Tried to compile it here on ubuntu 22.04, but i'm getting a error on the final of the build

error2.txt

[ToddAWalter]

Also-- Is there a reason vcpkg is used on linux? vcpkg is, no matter what microsoft says, designed for windows, and it doesn't make a ton of sense to have to compile all of the dependencies when they are already available in the various package managers.

It's not unheard of; blender-git ships siloed library trees (although via optional script, not a hard dependency) as they aren't shy about deploying fixes ahead of upstream. For code with frequent releases it's also helps avoid the packaging delay. Vulkan-headers are a month behind on Gentoo, for example.

[Jhackler]

't been involved in Cemu before, if you approve of it, wouldn't that make it official? Also, when it's ready for

saying it is allowed does not mean they want to provide support thus it is not official, just put community build or unofficial build in the name on flathub. You can also always submit your work back to the official project so they can choose weather to use some of your work in the official build or not.

Honestly, I just use make to have one less dependency (as it shouldn't change anything with CMake), but I will try with ninja to see if it changes everything
