# Build instructions
|
|
|
|
## Windows
|
|
|
|
Prerequisites:
|
|
- A recent version of Visual Studio 2022 (recommended but not required) with the following additional components:
|
|
- C++ CMake tools for Windows
|
|
- Windows 10/11 SDK
|
|
- git
|
|
|
|
Instructions:
|
|
|
|
1. Run `git clone --recursive https://github.com/cemu-project/Cemu`
|
|
2. Launch `Cemu/generate_vs_solution.bat`.
|
|
- If you installed VS to a custom location or use VS 2019, you may need to manually change the path inside the .bat file
|
|
3. Wait until it's done, then open `Cemu/build/Cemu.sln` in Visual Studio
|
|
4. Then build the solution and once finished you can run and debug it, or build it and check the /bin folder for the final Cemu.exe.
|
|
|
|
You can also skip steps 3-5 and open the root folder of the cloned repo directly in Visual Studio (as a folder) and use the built-in cmake support but be warned that cmake support in VS can be a bit finicky.
|
|
|
|
## Linux
|
|
|
|
To compile Cemu, a recent enough compiler and STL with C++20 support is required! clang-12 or higher is what we recommend.
|
|
|
|
### Installing dependencies
|
|
|
|
#### For Ubuntu and derivatives:
|
|
`sudo apt install -y git cmake ninja-build nasm libgtk-3-dev libsecret-1-dev libgcrypt20-dev libsystemd-dev freeglut3-dev libpulse-dev`
|
|
Additionally, for ubuntu 20.04 only:
|
|
- `sudo apt install -y clang-12`
|
|
- At step 3 while building, use
|
|
`cmake -S . -B build -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`
|
|
|
|
#### For Arch and derivatives:
|
|
`sudo pacman -S git cmake clang ninja nasm base-devel linux-headers gtk3 libsecret libgcrypt systemd freeglut zip libpulse`
|
|
|
|
#### For Fedora and derivatives:
|
|
`sudo dnf install git cmake clang ninja-build nasm kernel-headers gtk3-devel libsecret-devel libgcrypt-devel systemd-devel freeglut-devel perl-core zlib-devel cubeb-devel`
|
|
|
|
### Build Cemu using cmake
|
|
1. `git clone --recursive https://github.com/cemu-project/Cemu`
|
|
2. `cd Cemu`
|
|
3. `cmake -S . -B build -DCMAKE_BUILD_TYPE=release -DCMAKE_C_COMPILER=/usr/bin/clang -DCMAKE_CXX_COMPILER=/usr/bin/clang++ -G Ninja`
|
|
4. `cmake --build build`
|
|
5. You should now have a Cemu executable file in the /bin folder, which you can run using `./bin/Cemu`.
|
|
|
|
|
|
#### Troubleshooting steps
|
|
- If step 3 gives you an error about not being able to find ninja, try appending `-DCMAKE_MAKE_PROGRAM=/usr/bin/ninja` to the command and running it again.
|
|
- If step 3 fails while compiling the boost-build dependency, it means you don't have a working/good standard library installation. Check the integrity of your system headers and making sure that C++ related packages are installed and intact.
|
|
- If step 3 gives a random error, read the `[package-name-and-platform]-out.log` and `[package-name-and-platform]-err.log` for the actual reason to see if you might be lacking the headers from a dependency.
|
|
- If step 3 is still failing or if you're not able to find the cause, please make an issue on our Github about it!
|
|
- If step 4 gives you an error that contains something like `main.cpp.o: in function 'std::__cxx11::basic_string...`, you likely are experiencing a clang-14 issue. This can only be fixed by either lowering the clang version or using GCC, see below.
|
|
- If step 4 gives you a different error, you could report it to this repo or try using GCC. Just make sure your standard library and compilers are updated since Cemu uses a lot of modern features!
|
|
|
|
#### Using GCC
|
|
While we use and test Cemu using clang, using GCC might work better with your distro (they should be fairly similar performance/issues wise and should only be considered if compilation is the issue).
|
|
You can use it by replacing the step 3 with the following:
|
|
`cmake -S . -B build -DCMAKE_BUILD_TYPE=release -DCMAKE_C_COMPILER=/usr/bin/gcc -DCMAKE_CXX_COMPILER=/usr/bin/g++ -G Ninja`
