Build with Arduino-Makefile
This is a short tutorial for building games with Arduino-Makefile from the command line, instead of with the Arduino IDE. I ran these steps on 64bit Linux, but Arduino-Makefile is compatible with Mac and Windows too!
Why? I was already using an external code editor, so why not bypass the IDE all the way? Building this way is a lot faster too, I'm able to compile example sketches in 4 sec vs 14 sec with the IDE!
I first wrote this article on my website, check it out for a bit of extra content like customizing your project's structure.
1. Install Arduino
Install the Gamebuino META dev environment as normal, so you can build your game with the IDE.
2. Install Arduino-Makefile
I cloned the latest version to my home folder:
$ cd ~ $ git clone https://github.com/sudar/Arduino-Makefile
3. Choose a Project
Pick a sketch you want to build, and create a new file called
Makefile in its source folder (where the .ino file is). I'll use the Gamebuino META a_Hello example here:
$ cd ~/Arduino/libraries/Gamebuino_META/examples/1.Basics/a_Hello $ touch Makefile $ ls a_Hello.ino Makefile
4. Edit Makefile
Note that the
ALTERNATE_CORE_PATH paths below may be different on your system. You can check what they are by building with the IDE and looking at the output (remember to turn Verbose On from File > Preferences).
# Paths to Arduino IDE and cloned Arduino-Makefile ARDUINO_DIR = $(HOME)/arduino ARDMK_DIR = $(HOME)/Arduino-Makefile
# Specify the custom Gamebuino board and where it's installed
BOARD_TAG = gamebuino_meta_native
# The Arduino libraries the game uses
ARDUINO_LIBS = Gamebuino_META SPI
# The META lib expects SKETCH_NAME to be defined
CFLAGS += -D__SKETCH_NAME__="$(TARGET).ino"
CXXFLAGS += -D__SKETCH_NAME__="$(TARGET).ino"
# Now that everything is configured, include Arduino-Makefile
5. Build & Upload
$ make # Compile code and build .BIN file $ make upload # Flash to Gamebuino $ make clean # Remove all build files
All of these just work, even upload! You can build even faster with
make -j, which runs commands in parallel.
