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.

Resize Ghidra for High DPI screens

If you run Ghidra on a high DPI screen, you will probably find the GUI to be scaled down so small to be almost of no use.

There is a setting that you can adjust to scale the Ghidra GUI:

in $GHIDRA_ROOT/support is a file named launch.properties. In this launch.properties file is the following configuration key:

VMARGS_LINUX=-Dsun.java2d.uiScale=1

The command I use to archive a single website

wget -mpck --html-extension --user-agent="" -e robots=off --wait 1 -P . www.foo.com

Explanation of the parameters used

-m (Mirror) Turns on mirror-friendly settings like infinite recursion depth, timestamps, etc.
