## Development

If you want to contribute please take a look at the [Coding Style](https://github.com/RPCS3/rpcs3/wiki/Coding-Style), [Roadmap](https://github.com/RPCS3/rpcs3/wiki/Roadmap) and [Developer Information](https://github.com/RPCS3/rpcs3/wiki/Developer-Information) pages. You should as well contact any of the developers in the forums or in Discord in order to know more about the current situation of the emulator.


## Dependencies

### Windows
* [Visual Studio 2015](https://www.visualstudio.com/vs/older-downloads/)
* [Visual C++ Redistributable Packages for Visual Studio 2015](http://www.microsoft.com/en-us/download/details.aspx?id=48145)
* [Cmake 3.1.0+](https://www.cmake.org/download/) (required; add to PATH)
* [Python 3.3+](https://www.python.org/downloads/) (required; add to PATH)
* [Qt 5.10+](https://www.qt.io/download-open-source/) (required; add QTDIR environment variable if you do not want to use the Visual Studio Qt Plugin: e.g. `<QtInstallFolder>\5.10.1\msvc2015_64\`)
* [Visual Studio Qt Plugin](https://marketplace.visualstudio.com/items?itemName=TheQtCompany.QtVisualStudioTools2015) (optional; see above)
* [Vulkan SDK](https://sdk.lunarg.com/sdk/download/1.1.73.0/windows/VulkanSDK-1.1.73.0-Installer.exe) (required)

### Linux
* [Qt 5.10+](https://www.qt.io/download-open-source/)
* GCC 5.1+ or Clang 3.5.0+ ([not GCC 6.1](https://github.com/RPCS3/rpcs3/issues/1691))
* Debian & Ubuntu: `sudo apt-get install cmake build-essential libasound2-dev libpulse-dev libopenal-dev libglew-dev zlib1g-dev libedit-dev libvulkan-dev libudev-dev git qt5-default`
* Arch: `sudo pacman -S glew openal cmake vulkan-validation-layers qt5-base`
* Fedora: `sudo dnf install alsa-lib-devel cmake glew glew-devel libatomic libevdev-devel libudev-devel openal-devel qt5-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`

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

### MacOS
MacOS is not supported at this moment because it doesn't meet system requirements (OpenGL 4.3)
* Xcode 6+ (tested with Xcode 6.4)
* Install with Homebrew: `brew install glew llvm qt cmake`


## Building on Windows:
To initialize the repository don't forget to execute `git submodule update --init` to pull the submodules.

### Configuring Qt

*If you're using Visual Studio 2017 without Qt plugin support (or simply dont want to use it):* 
1) Add `QTDIR` environment variable and set it to e.g `<QtInstallFolder>\5.10.1\msvc2015_64\` </br>


*If you're using Visual Studio 2017, when you first open the project, do not upgrade the targets or the packages. Leave both at "No upgrade". Note that you will need the v140 toolset, which may not be in 2017 by default.* </br>

Open `rpcs3.sln`


*If you wish to use the Visual Studio plugin for Qt:* </br>
1) Go to the Qt5 menu and edit Qt5 options. Add the path to your Qt installation with compiler e.g. `C:\Qt\5.10.1\msvc2015_64`. </br>
2) While selecting the rpcs3qt project, go to Qt5->Project Setting and select the version you added. 

### Building the projects
The recommended build configuration is Release - LLVM, for all purposes. </br> </br>
You may want to download precompiled [LLVM lib](https://drive.google.com/uc?export=download&id=0B8A6NaxhQAGRY2k3Q2Yya05lcm8) and extract to root rpcs3 folder (which contains `rpcs3.sln`), as well as download and extract [additional libs](https://drive.google.com/uc?export=download&id=0B8A6NaxhQAGRaHYxV3VOS2d0a0U) to `lib\%CONFIGURATION%-x64\` to speed up compilation time (unoptimised/debug libs are currently not available precompiled).

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

`Build > Build Solution`</br>



## Building on Linux & Mac OS:

1) `git clone https://github.com/RPCS3/rpcs3.git` </br>
2) `cd rpcs3/` </br>
3) `git submodule update --init` </br>
4) `cd ../ && mkdir rpcs3_build && cd rpcs3_build`
4) `cmake ../rpcs3/ && make GitVersion && make` </br>
5) Run RPCS3 with `./bin/rpcs3` </br>

If you are on MacOS and want to build with brew llvm and qt don't forget to add the following environment variables

 * `LLVM_DIR=/usr/local/opt/llvm/` (or wherever llvm was installed).
 * `Qt5_DIR=/usr/local/opt/qt/lib/cmake/Qt5` (or wherever qt was installed).

When using GDB, configure it to ignore SIGSEGV signal (`handle SIGSEGV nostop noprint`).


## CMake Build Options (Linux & Mac OS)

- ```-DUSE_SYSTEM_LIBPNG=ON/OFF``` (default = *OFF*)  
Build against the shared libpng instead of using the builtin one. libpng 1.6+ highly recommended. Try this option if you get version conflict errors or only see black game icons.

- ```-DUSE_SYSTEM_FFMPEG=ON/OFF``` (default = *OFF*)  
Build against the shared ffmpeg libraries instead of using the builtin patched version. Try this if the builtin version breaks the OpenGL renderer for you.

- ```-DWITHOUT_LLVM=ON/OFF``` (default = *OFF*)  
This forces RPCS3 to build without LLVM, not recommended.

- ```-DWITH_GDB=ON/OFF``` (default = *OFF*)  
This Builds RPCS3 with support for debugging PS3 games using gdb.

- ```-DUSE_VULKAN=ON/OFF``` (default = *ON*)  
This builds RPCS3 with Vulkan support.

- ```-DUSE_NATIVE_INSTRUCTIONS=ON/OFF``` (default = *ON*)  
This builds rpcs3 with -march=native, which is useful for local builds, but not good for packages.
