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 7 or later

Either add the QTDIR environment variable, e.g. <QtInstallFolder>\5.15.2\msvc2019_64\ , or use the Visual Studio Qt Plugin

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 qt5-base qt5-declarative sdl2

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

Ubuntu is usually horrendously out of date, and some packages need to be downloaded by hand.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 a PPA available to work around this. Run the following:

. /etc/os-release
sudo add-apt-repository ppa:beineri/opt-qt-5.15.2-$UBUNTU_CODENAME
sudo apt-get update
sudo apt-get install qt515-meta-minimal qt515svg
. /opt/qt515/bin/qt515-env.sh >/dev/null 2>&1
GCC 9.x installation

If the gcc-9 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-9 g++-9

You can either use update-alternatives to setup gcc-9/g++-9 as your default compilers or prefix any cmake command by CXX=g++-9 CC=gcc-9 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.

. /etc/os-release
wget -qO - https://packages.lunarg.com/lunarg-signing-key-pub.asc | sudo apt-key add -
sudo wget -qO /etc/apt/sources.list.d/lunarg-vulkan-1.2.148-$UBUNTU_CODENAME.list https://packages.lunarg.com/vulkan/1.2.148/lunarg-vulkan-1.2.148-$UBUNTU_CODENAME.list
sudo apt update
sudo apt install vulkan-sdk
CMake
. /etc/os-release
wget -O - https://apt.kitware.com/keys/kitware-archive-latest.asc 2>/dev/null | sudo apt-key add -
sudo apt-add-repository "deb https://apt.kitware.com/ubuntu/ $UBUNTU_CODENAME main"
sudo apt-get update
sudo apt-get install kitware-archive-keyring
sudo apt-key --keyring /etc/apt/trusted.gpg del C1F34CDD40CD72DA
sudo apt-get install cmake

Fedora

sudo dnf install alsa-lib-devel cmake glew glew-devel libatomic libevdev-devel libudev-devel openal-devel qt5-qtbase-devel qt5-qtbase-private-devel vulkan-devel

OpenSUSE

sudo zypper install git cmake libasound2 libpulse-devel openal-soft-devel glew-devel zlib-devel libedit-devel vulkan-devel libudev-devel libqt5-qtbase-devel libevdev-devel

Setup the project

Clone and initialize the repository

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

Windows

Configuring the Qt plugin (if used)

  1. Go to the Qt5 menu and edit Qt5 options.
  2. Add the path to your Qt installation with compiler e.g. <QtInstallFolder>\5.15.2\msvc2019_64.
  3. While selecting the rpcs3qt project, go to Qt5->Project Setting and select the version you added.

Building the projects

Open rpcs3.sln. The recommended build configuration is Release - LLVM for all purposes.

You may want to download the precompiled LLVM libs and extract them to the root rpcs3 folder (which contains rpcs3.sln), as well as download and extract the additional libs to lib\%CONFIGURATION%-x64\ to speed up compilation time (unoptimised/debug libs are currently not available precompiled).

If you're not using the precompiled libs, build the projects in __BUILD_BEFORE folder: right-click on every project > Build.

Build > Build Solution

Linux

While still in the project root:

  1. cd .. && mkdir rpcs3_build && cd rpcs3_build
  2. cmake ../rpcs3/ && make or CXX=g++-9 CC=gcc-9 cmake ../rpcs3/ && make to force these compilers
  3. Run RPCS3 with ./bin/rpcs3

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