- Multi platform. Runs on Windows, Linux, Mac OS X, Raspberry Pi, iOS and as a libretro core (RetroArch).
- Install Xcode for Mac OS X. You need iOS SDK 8 or later.
- Build the project.
- Run it on real hardware using your iOS developer certificate. Make sure it compiles on Release for extra optimizations.
- For jailbroken devices use the jailbreak branch.
Raspberry Pi 2 & 3 - Raspbian
- Install and configure SDL 2 for development:
sudo apt-get update sudo apt-get upgrade sudo apt-get install build-essential libfreeimage-dev libopenal-dev libpango1.0-dev libsndfile-dev libudev-dev libasound2-dev libjpeg-dev libtiff5-dev libwebp-dev automake cd ~ wget https://www.libsdl.org/release/SDL2-2.0.8.tar.gz tar zxvf SDL2-2.0.8.tar.gz cd SDL2-2.0.8 && mkdir build && cd build ../configure --disable-pulseaudio --disable-esd --disable-video-mir --disable-video-wayland --disable-video-x11 --disable-video-opengl --host=armv7l-raspberry-linux-gnueabihf make -j 4 sudo make install
- Install libconfig library dependencies for development:
sudo apt-get install libconfig++-dev.
make -j 4in the
platforms/raspberrypi3/Gearsystem/folder to build the project.
export SDL_AUDIODRIVER=ALSAbefore running the emulator for the best performance.
- Gearsystem generates a
gearsystem.cfgconfiguration file where you can customize keyboard and gamepads. Key codes are from SDL.
- You need Visual Studio 2015.
- Install the Qt 5 Open Source SDK for Windows.
- Install the QtPackage Extension and point it to the Qt SDK.
- Open the Gearsystem Visual Studio project and build.
Mac OS X
- You need Qt Creator, included in the Qt 5 SDK.
- Install Xcode and run
xcode-select --installin the terminal for the compiler to be available on the command line.
- Install the Qt 5 SDK for Mac OS.
- Download SDL 2 source code. Then run this commands:
./configure make sudo make install
- Ubuntu / Debian:
sudo apt-get install build-essential qt5-default qttools5-dev-tools freeglut3-dev libsdl2-dev libglew-dev cd platforms/linux/Gearsystem qmake Gearsystme.pro && make
sudo dnf install qt5-devel freeglut-devel SDL2-devel glew-devel cd platforms/linux/Gearsystem qmake-qt5 Gearsystem.pro && make
