Usage

Add this mruby gem to your build_config.rb

conf.gem github: "cyberarm/mruby-gosu"

Development

Unix

Install Gosu as a system library, see wiki. (Note: may need to edit gosu/build/cmake_install.cmake to change set(CMAKE_INSTALL_PREFIX "/usr/local") to set(CMAKE_INSTALL_PREFIX "/usr") before running sudo make install)

Sample MRuby Build Configuration

MRuby::Build.new do |conf|
  conf.toolchain
  # include the default GEMs
  conf.gembox "default"
  conf.gem github: "cyberarm/mruby-gosu"
  conf.gem github: "mattn/mruby-require"
  # C compiler settings
  conf.cc.defines = %w(MRB_USE_DEBUG_HOOK MRB_INT64)
  conf.enable_debug
  conf.enable_cxx_abi
  conf.enable_test
end

Windows

Clone Gosu
Build Gosu as a Release for x86 or x64 with Visual Studio 19 or 22
Copy the built gosu-ffi.lib file into to the /gosu/lib/ directory or /gosu/lib64/ for x64
Visual Studio should have placed Gosu.lib into the same directory
Open a MSYS2 console or use $env:Path += ";PATH_TO_UCRT_BIN" in PowerShell
Build MRuby e.g. rake MRUBY_CONFIG=gosu --verbose
Copy gosu-ffi.dll and SDL2.dll into /mruby/bin/

MSYS2 UCRT

Sample MRuby Build configuration

MRuby::Build.new do |conf|
  conf.toolchain :gcc
  # include the default GEMs
  conf.gembox "default"
  conf.gem github: "cyberarm/mruby-gosu"
  conf.gem github: "mattn/mruby-require"
  # C compiler settings
  conf.cc.defines << "MRB_INT64"
  conf.cc.flags << "-fpermissive" # Needed for mruby-require
  conf.enable_cxx_abi
  conf.enable_debug
end

Visual C++

No instructions available yet.

MSYS2 UCRT's instructions might work with MSVC 140 sans :gcc (I had 143 installed)
