# Build instructions ## Windows Prerequisites: - A recent version of Visual Studio 2022 with CMake tools component - git - Vulkan SDK ([https://vulkan.lunarg.com/](https://vulkan.lunarg.com/)). Don't forget to restart after installing. Instructions: 1) Run `git clone --recursive https://github.com/cemu-project/Cemu` 2) Launch `Cemu/build_vs_solution.bat`. If you installed VS to a custom location you may need to manually adjust the path inside the bat file 3) Wait until done, then open build/Cemu.sln in Visual Studio 4) Right click 'CemuBin' project -> Set as startup project 5) Then build the solution and once finished you can run and debug it 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 inbuilt 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! We use clang 12, other compilers may work as well. For ubuntu and most derivatives: `sudo apt install -y libgtk-3-dev libsecret-1-dev libgcrypt20-dev libsystemd-dev freeglut3-dev clang-12 nasm` For Arch and most derivatives: `sudo pacman -S --needed gtk3 libsecret libgcrypt systemd-libs freeglut nasm` For Fedora and most derivatives: `sudo dnf in -y gtk3-devel libsecret-devel libgcrypt-devel systemd-devel freeglut-devel clang12-libs nasm cmake vcpkg perl-core zlib-devel` 1) Make sure vulkansdk is installed and the VULKAN_SDK environment variable is set correctly. 2) Run `git clone --recursive https://github.com/cemu-project/Cemu` 3) `cd Cemu` 4) `mkdir build && cd build` 5) `cmake .. -DCMAKE_BUILD_TYPE=release -DCMAKE_C_COMPILER=/usr/bin/clang -DCMAKE_CXX_COMPILER=/usr/bin/clang++ -G Ninja -DCMAKE_BUILD_WITH_INSTALL_RPATH=ON -DCMAKE_MAKE_PROGRAM=/usr/bin/ninja` 6) `ninja` Build instructions for other distributions will be added in the future!
