Building

Only Windows and Linux are officially supported for building. However, various other platforms are capable of building RPCS3. Other instructions may be found here.

Setup your environment

Windows 10 or later

The following tools are required to build RPCS3 on Windows 10 or later:

The sln solution available only on Visual Studio is the preferred building solution. It easily allows to build the RPCS3 application in Release and Debug mode.

In order to build RPCS3 with the sln solution (with Visual Studio), Qt libs need to be detected. To detect the libs:

  • add and set the QTDIR environment variable, e.g. <QtInstallFolder>\6.8.1\msvc2022_64\

  • or use the Visual Studio Qt Plugin

    NOTE: If you have issues with the Visual Studio Qt Plugin, you may want to uninstall it and install the Legacy Qt Plugin instead.

In order to build RPCS3 with the CMake solution (with both Visual Studio and standalone CMake tool):

  • add and set the CMAKE_PREFIX_PATH environment variable to the Qt libs path, e.g. <QtInstallFolder>\6.8.1\msvc2022_64\

Linux

These are the essentials tools to build RPCS3 on Linux. Some of them can be installed through your favorite package manager:

If you have an NVIDIA GPU, you may need to install the libglvnd package.

Arch Linux

sudo pacman -S glew openal cmake vulkan-validation-layers qt6-base qt6-declarative qt6-multimedia qt6-svg sdl2 sndio jack2 base-devel

Debian & Ubuntu

sudo apt-get install build-essential libasound2-dev libpulse-dev libopenal-dev libglew-dev zlib1g-dev libedit-dev libvulkan-dev libudev-dev git libevdev-dev libsdl2-2.0 libsdl2-dev libjack-dev libsndio-dev

Ubuntu is usually horrendously out of date, and some packages need to be downloaded by hand. This part is for Qt, GCC, Vulkan, and CMake

Qt PPA

Ubuntu usually does not have a new enough Qt package to suit rpcs3's needs. There is currently no PPA available to work around this.

GCC 13.x installation

If the gcc-13 package is not available on your system, use the following commands

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-13 g++-13

You can either use update-alternatives to setup gcc-13/g++-13 as your default compilers or prefix any cmake command by CXX=g++-13 CC=gcc-13 to use it.

Vulkan SDK

For Ubuntu systems, it is strongly recommended to use the PPA from LunarG which will provide a compatible Vulkan SDK to compile RPCS3. If your Vulkan SDK is older, it can lead to compilation errors.

Setup the project

Clone and initialize the repository

git clone https://github.com/RPCS3/rpcs3.git
cd rpcs3
git submodule update --init

Windows

Building with Visual Studio sln solution

Start Visual Studio, click on Open a project or solution and select the rpcs3.sln file inside the RPCS3's root folder

Configuring the Qt Plugin (if used)
  1. go to Extensions->Qt VS Tools->Qt Versions
  2. add the path to your Qt installation with compiler e.g. <QtInstallFolder>\6.8.1\msvc2022_64, version will fill in automatically
  3. go to Extensions->Qt VS Tools->Options->Legacy Project Format. (Only available in the Legacy Qt Plugin)
  4. set Build: Run pre-build setup to true. (Only available in the Legacy Qt Plugin)
Building the projects

NOTE: The recommended build configuration is Release. (On older revisions: Release - LLVM)

To speed up the compilation time, you may want to download and extract to <rpcs3_root>\build\lib_ext\<$(Configuration)>-x64 (e.g. c:\rpcs3\build\lib_ext\Release-x64; the path needs to be created) some of the following precompiled libs:

NOTES:

  • <$(Configuration)> can assume values Release or Debug.
  • Unoptimised/debug libs are currently not available precompiled for both LLVM and glslang. Trying to use them when building the RPCS3 application in Debug mode will provide a cannot open file error.

If you're not using the precompiled libs, those dependency libs need to be compiled first. From the Solution Explorer panel:

  1. expand __BUILD_BEFORE
  2. from the Solution Configurations drop-down menu, select Release (select Debug if you want to build in Debug mode)
  3. one after another, right-click on the following projects and then click on Build to build the selected lib:
    • glslang
    • llvm_build
    • or llvm_build_clang_cl (if you have also the clang compiler installed on VS)

NOTE: Compiled dependency libs have priority over precompiled libs, if installed. It means that they will always be referenced and linked in case the precompiled libs are also available.

In order to build the RPCS3 application:

  1. from the Solution Configurations drop-down menu, select Release (select Debug if you want to build in Debug mode)

    NOTE: In case you previously compiled the dependency libs under __BUILD_BEFORE, you have also to select the same build configuration (e.g. Release, if you compiled the dependency libs in Release mode)

  2. click on Build menu and then on Build Solution

  3. once the build is completed, the RPCS3 application will be available under the <rpcs3_root>\bin folder

Building with Visual Studio CMake solution

Start Visual Studio, click on Open a local folder and select the RPCS3's root folder

Once the project is open on VS, from the Solution Explorer panel:

  1. right-click on rpcs3 and then click on Switch to CMake Targets View
  2. from the Configuration drop-down menu, select msvc-release (select msvc-debug if you want to build in Debug mode)
  3. right-click on CMakeLists.txt Project and then click on Configure Cache
  4. once the cache is created, the rpcs3 project will be available
  5. right-click on rpcs3 Project and then click on Build All, or click on Build menu and then on Build All
  6. once the build is completed, the RPCS3 application will be available under the <rpcs3_root>\build-msvc\bin folder

Building with standalone CMake tool

In case you preferred to install and use the standalone CMake tool:

  1. move on the RPCS3's root folder

  2. execute the following commands to create the cache and to build the application (for the build, use --preset msvc-debug if you want to build in Debug mode), respectively:

    cmake --preset msvc
cmake --build --preset msvc-release

  3. once the build is completed, the RPCS3 application will be available under the <rpcs3_root>\build-msvc\bin folder

Linux

While still in the project root:

  1. cd .. && mkdir --parents rpcs3_build && cd rpcs3_build
  2. cmake ../rpcs3/ && make or CXX=g++-13 CC=gcc-13 cmake ../rpcs3/ && make to force these compilers
  3. run RPCS3 with ./bin/rpcs3

If compiling for ARM, pass the flag -DUSE_NATIVE_INSTRUCTIONS=OFF to the cmake command. This resolves some Neon errors when compiling our SIMD headers.

When using GDB, configure it to ignore SIGSEGV signal (handle SIGSEGV nostop noprint). If desired, use the various build options in CMakeLists.
