Build Instructions

Windows

  • Install Microsoft Visual Studio Community 2019 or later.
  • Open the Gearboy Visual Studio solution platforms/windows/Gearboy.sln and build.
  • You may want to use the platforms/windows/Makefile to build the application using MinGW.

macOS

  • Install Xcode and run xcode-select --install in the terminal for the compiler to be available on the command line.
  • Run these commands to generate a Mac app bundle:
brew install sdl2
cd platforms/macos
make dist

Linux

  • Ubuntu / Debian:
sudo apt-get install build-essential libsdl2-dev libglew-dev
cd platforms/linux
make
  • Fedora:
sudo dnf install @development-tools gcc-c++ SDL2-devel glew-devel
cd platforms/linux
make

BSD

  • NetBSD:
su root -c "pkgin install gmake pkgconf SDL2 glew"
cd platforms/bsd
gmake

iOS

  • Install latest Xcode for macOS.
  • Build the project platforms/ios/Gearboy.xcodeproj.
  • Run it on real hardware using your iOS developer certificate. Make sure it builds on Release for better performance.

Libretro

  • Ubuntu / Debian:
sudo apt-get install build-essential
cd platforms/libretro
make
  • Fedora:
sudo dnf install @development-tools gcc-c++
cd platforms/libretro
make

Raspberry Pi 4 - Raspbian (Desktop)

sudo apt install build-essential libsdl2-dev libglew-dev
cd platforms/raspberrypi4
make

Raspberry Pi 2 & 3 - Raspbian (CLI)

  • 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/SDL2-2.0.12.tar.gz
tar zxvf SDL2-2.0.12.tar.gz
cd SDL2-2.0.12 && 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
  • Use make -j 4 in the platforms/raspberrypi3/x64/ folder to build the project.
  • Use export SDL_AUDIODRIVER=ALSA before running the emulator for the best performance.
  • Gearboy generates a gearboy.cfg configuration file where you can customize keyboard and gamepads. Key codes are from SDL.
