6. Run `duckstation-qt-x64-Release.exe` or whichever config you used.
### Linux
Requirements (Debian/Ubuntu package names):
- CMake (`cmake`)
- SDL2 (at least version 2.30.2) (`libsdl2-dev` `libxrandr-dev`)
- pkgconfig (`pkg-config`)
- Qt 6 (at least version 6.7.0) (`qt6-base-dev` `qt6-base-private-dev` `qt6-base-dev-tools` `qt6-tools-dev` `libqt6svg6`)
- git (`git`) (Note: needed to clone the repository and at build time)
- When Wayland is enabled (default): (`libwayland-dev` `libwayland-egl-backend-dev` `extra-cmake-modules` `qt6-wayland`)
- libcurl (`libcurl4-openssl-dev`)
- Optional for faster building: Ninja (`ninja-build`)
Due to Ubuntu LTS using older package versions, DuckStation releases use manually built dependency libraries. If you are using a distribution with older package versions, you can build the required library versions using the script found at https://github.com/stenzek/duckstation/blob/master/scripts/build-dependencies.sh.
#### Required Dependencies
Fedora package names (assumes you are using the dependency build script):

1. Clone the repository: `git clone https://github.com/stenzek/duckstation.git -b dev`.
2. Create a build directory, either in-tree or elsewhere.
3. Run CMake to configure the build system. Assuming a build subdirectory of `build-release`, run `cmake -Bbuild-release -DCMAKE_BUILD_TYPE=Release`. If you have installed Ninja, add `-GNinja` at the end of the CMake command line for faster builds. If you used the dependency build script, the path you built the dependencies in should be supplied with `-DCMAKE_PREFIX_PATH=/path/to/deps`.
4. Compile the source code. For the example above, run `cmake --build build-release --parallel`.
5. Run the binary, located in the build directory under `bin/duckstation-qt`.
#### Building
1. Clone the repository: `git clone https://github.com/stenzek/duckstation.git`, `cd duckstation`.
2. Build dependencies. You can save these outside of the tree if you like. This will take a while. `scripts/linux/build-dependencies-linux.sh deps`.
3. Run CMake to configure the build system. Assuming a build subdirectory of `build-release`, run `cmake -B build-release -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_EXE_LINKER_FLAGS_INIT="-fuse-ld=lld" -DCMAKE_MODULE_LINKER_FLAGS_INIT="-fuse-ld=lld" -DCMAKE_SHARED_LINKER_FLAGS_INIT="-fuse-ld=lld" -DCMAKE_PREFIX_PATH="$PWD/deps" -G Ninja`.
4. Compile the source code. For the example above, run `ninja -C build`
5. Run the binary, located in the build directory under `./build-release/bin/duckstation-qt`.
