Dependencies

You'll need to download and install the following to build yuzu:

  • GCC v11+ (for C++20 support) & misc
    • This page is being updated as we transition to GCC 11
  • If GCC 12 is installed, Clang v14+ is required for compiling
  • CMake 3.15+

The following are handled by yuzu's externals:

If version 5.15.2 is not already installed, pre-compiled binaries for Qt 5.15.2 will be downloaded from here automatically by CMake:

  • Qt 5.15+

All other dependencies will be downloaded by vcpkg if needed:

If an ARM64 build is intended, export VCPKG_FORCE_SYSTEM_BINARIES=1.

Dependencies are listed here as commands that can be copied/pasted. Of course, they should be inspected before being run.

  • Arch / Manjaro:
    • sudo pacman -Syu --needed base-devel boost catch2 cmake ffmpeg fmt git glslang libzip lz4 mbedtls ninja nlohmann-json openssl opus qt5 sdl2 zlib zstd zip unzip
    • Building with QT Web Engine needs to be specified when running CMake with the param -DCMAKE_CXX_FLAGS="-I/usr/include/qt/QtWebEngineWidgets" with qt5-webengine installed.
    • GCC 11 or later is required.
  • Ubuntu / Linux Mint / Debian:
    • sudo apt-get install autoconf cmake g++-11 gcc-11 git glslang-tools libasound2 libboost-context-dev libglu1-mesa-dev libhidapi-dev libpulse-dev libtool libudev-dev libxcb-icccm4 libxcb-image0 libxcb-keysyms1 libxcb-render-util0 libxcb-xinerama0 libxcb-xkb1 libxext-dev libxkbcommon-x11-0 mesa-common-dev nasm ninja-build qtbase5-dev qtbase5-private-dev qtwebengine5-dev qtmultimedia5-dev libmbedtls-dev catch2 libfmt-dev liblz4-dev nlohmann-json3-dev libzstd-dev libssl-dev libavfilter-dev libavcodec-dev libswscale-dev
    • Ubuntu 22.04, Linux Mint 20, or Debian Bullseye or later is required.
    • Users need to manually specify building with QT Web Engine enabled. This is done using the parameter -DYUZU_USE_QT_WEB_ENGINE=ON when running CMake.
    • Users need to manually specify building with GCC 11. This can be done by adding the parameters -DCMAKE_C_COMPILER=gcc-11 -DCMAKE_CXX_COMPILER=g++-11 when running CMake. i.e.
    • Users need to manually disable building SDL2 from externals if they intend to use the version provided by their system by adding the parameters -DYUZU_USE_EXTERNAL_SDL2=OFF
git submodule update --init --recursive
cmake .. -GNinja -DCMAKE_C_COMPILER=gcc-11 -DCMAKE_CXX_COMPILER=g++-11
  • Fedora:
    • sudo dnf install autoconf ccache cmake fmt-devel gcc{,-c++} glslang hidapi-devel json-devel libtool libusb1-devel libzstd-devel lz4-devel nasm ninja-build openssl-devel pulseaudio-libs-devel qt5-linguist qt5-qtbase{-private,}-devel qt5-qtwebengine-devel qt5-qtmultimedia-devel speexdsp-devel wayland-devel zlib-devel ffmpeg-devel libXext-devel
    • Fedora 32 or later is required.
    • Due to GCC 12, Fedora 36 or later users need to install clang, and configure CMake to use it via -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_C_COMPILER=clang
    • CMake arguments to force system libraries:
      • SDL2: -DYUZU_USE_BUNDLED_SDL2=OFF -DYUZU_USE_EXTERNAL_SDL2=OFF
      • FFmpeg: -DYUZU_USE_EXTERNAL_FFMPEG=OFF
    • RPM Fusion (free) is required to install ffmpeg-devel
  • Gentoo:
    • **Disclaimer**: this dependency list was written by a novice Gentoo user who first set it up with a DE, and then based this list off of the Fedora dependency list. This may be missing some requirements, or includes too many. Caveat emptor.
    • emerge --ask app-arch/lz4 dev-libs/boost dev-libs/hidapi dev-libs/libzip dev-libs/openssl dev-qt/linguist dev-qt/qtconcurrent dev-qt/qtcore dev-util/cmake dev-util/glslang dev-vcs/git media-libs/alsa-lib media-libs/opus media-sound/pulseaudio media-video/ffmpeg net-libs/mbedtls sys-libs/zlib x11-libs/libXext
    • GCC 11 or later is required.
    • Users may need to append pulseaudio, bindist and context to the USE flag.

Cloning yuzu with Git

from Codeberg repo (the --recursive option automatically clones the required Git submodules):

git clone --depth 1 --recursive https://codeberg.org/litucks/torzu.git
cd torzu

from Torzu repo (assuming Tor is installed as a service):

git -c http.proxy=socks5h://127.0.0.1:9050 clone --depth 1 http://vub63vv26q6v27xzv2dtcd25xumubshogm67yrpaz2rculqxs7jlfqad.onion/torzu-emu/torzu.git
cd torzu
git submodule update --init --recursive

Building yuzu in Release Mode (Optimized)

If you need to run ctests, you can disable -DYUZU_TESTS=OFF and install Catch2.

mkdir build && cd build
cmake .. -GNinja -DYUZU_USE_BUNDLED_VCPKG=ON -DYUZU_TESTS=OFF
ninja
sudo ninja install

Optionally, you can use cmake-gui .. to adjust various options (e.g. disable the Qt GUI).

Building yuzu in Debug Mode (Slow)

mkdir build && cd build
cmake .. -GNinja -DCMAKE_BUILD_TYPE=Debug -DYUZU_USE_BUNDLED_VCPKG=ON -DYUZU_TESTS=OFF
ninja

Building with debug symbols

mkdir build && cd build
cmake .. -GNinja -DCMAKE_BUILD_TYPE=RelWithDebInfo -DYUZU_USE_BUNDLED_VCPKG=ON -DYUZU_TESTS=OFF
ninja

Running without installing

After building, the binaries yuzu and yuzu-cmd (depending on your build options) will end up in build/bin/.

# SDL
cd build/bin/
./yuzu-cmd

# Qt
cd build/bin/
./yuzu

Debugging

  1. Enable CPU debugging
  2. Disable both Host MMU emulation options
  3. Run gdb
cd data
gdb ../build/bin/yuzu            # Start GDB
(gdb) handle SIGSEGV nostop      # Disable SIGSEGV exceptions, which are used by yuzu for memory access
(gdb) run                        # Run yuzu under GDB
<crash>
(gdb) bt                         # Print a backtrace of the entire callstack to see which codepath the crash occurred on
