A small x86 OS and userspace. It doesn't aim to be POSIX compliant, and will support most features of LibC.
This should probably by done on a *NIX with a recent GCC cross-compiler built for the i686-elf target.
If grub-mkrescue complains, try running sudo apt install xorriso grub-pi-bin (or equivalent).
- Build with
make - Clean environment with
make clean - Emulate with
make qemu
Building the ISO yourself is fine, but distributing the resultant .iso infringes the GPL, because
grub-mkrescue includes code from GRUB. You either can't distribute the ISO or have to also distribute the entire
GRUB source.
