If you want to have modern C++ (for instance), you basically have to cross-compile. If only using C or older g++, I'd compile inside the Amiga, I think. https://github.com/Slamy/m68k-elf-gcc - can generate bootable floppies! https://github.com/bebbo/amiga-gcc - modern (gcc-13.2) C and C++ for cross-compiling from Mac/Linux/Windows. It even supports the post-Motorola 68080 Natami VHDL CPU extensions.

An interesting way IME to learn C, is to code for an old platform like the Amiga. All the same best practices apply, but the underlying OS is more simple and the constraints, like missing floating point, forces you investigate many aspects of C. You can use Bebbo's m68k cross compiler to compile for the platform: https://github.com/bebbo/amiga-gcc No single source of truth for C best practices exist, but I can recommend using static analyzers like: https://splint.org/ and http://cppcheck.sourceforge.net/ to steer you in the right direction. Also, compile your code with the following gcc options: -pedantic -std=<c99 or c89> -ggdb3 -O0 -Wall -Wextra -Wformat=2 -Wmissing-include-dirs -Winit-self -Wswitch-default -Wswitch-enum -Wunused-parameter -Wfloat-equal -Wundef -Wshadow -Wlarger-than-1000 -Wunsafe-loop-optimizations -Wbad-function-cast
