Made an operating system. I based if off of NanoByte's tutorial and from there I added a shell and stuff. I implemented memory management, CPU scheduling, interrupt handling, threading, and a FAT32 filesystem.
I will make a better showcase in the future
Here are the arch specific things you need. If you are on anything else, find the equivalent or add it here yourself...
yay -S gcc make bison flex libgmp-static libmpc mpfr texinfo nasm mtools qemu-system-x86 python3 scons # or paru
Then you must run
uv venv
source .venv/bin/activate
uv pip install -r requirements.txt
or
python3 -m pip install -r requirements.txt
Next, modify the configuration in build_scripts/config.py. The most important is the toolchain='../.toolchains' option which sets where the toolchain will be downloaded and built. The default option is in the directory above where the repo is cloned, in a .toolchains directory, but you will get an error if this directory doesn't exist.
After that, run scons toolchain, this should download and build the required tools (binutils and GCC). If you encounter errors during this step, you might have to modify scripts/setup_toolchain.sh and try a different version of binutils and gcc. Using the same version as the one bundled with your distribution is your best bet.
Finally, you should be able to run scons. Use scons run to test your OS using qemu.
