Compiling GBA programs on Linux with GCC

There is a strange lack of guides and tools online for compiling Gameboy Advance homebrew programs on Linux. I didn't want to use devkitpro - their installation method of requiring you to use a forked version of pacman is extemely strange and I didn't want to install all of that on my system just to complile some programs.

The only other guides I found for Linux were this one and this one which both involve compiling custom versions of GCC and assosicated libraries. This lead me down a road of pain, after spending multiple hours fixing compiler errors only to create new errors I gave up. I thought that their had to be a simpler way, and there is!

The solution

Debian already has a version of GCC that can compile ARM programs in the repos, no manual compiling necessary! The package is called arm-none-eabi-gcc.

How to publish Python apps for human beings

So, you've created a Python app (be it a graphical user interface with Qt or the like, or a simple command line interface). Great! But how are others going to use it? Python applications often have dependencies (e.g. from third-party modules), and they also need a Python interpreter to run them. For a developer, installing all the necessary bits and bobs to make things work is okay, but that's unacceptable for a normal user - they just want to download the thing and run it.

Below are simple instructions to publish your app on the three main operating systems: Windows, macOS and Linux.

	cmake_minimum_required( VERSION 3.6 )

	set( CMAKE_CXX_STANDARD 11 )
	set( CMAKE_CXX_STANDARD_REQUIRED ON )
	set( CMAKE_CXX_EXTENSIONS OFF )

	find_package( Git )
	execute_process(
	COMMAND ${GIT_EXECUTABLE} clone "https://github.com/ocornut/imgui.git" -b v1.72b
	WORKING_DIRECTORY ${CMAKE_CURRENT_BINARY_DIR}
