These tools produce platform independent output so you may wish to install them

This will compile a basic Sortix system into ~/sortix/sysroot with a kernel,
headers, libraries, programs, everything you need. This isn't a bootable system
yet. If you have xorriso and grub-mkrescue from GRUB 2 installed, then you can
yet. You need the combination of a kernel and an initrd to boot Sortix. The
initrd is a root filesystem entirely in memory that is loaded by the bootloader
in addition to the kernel. You can generate the initrd in builds/ by running:
cd ~/sortix &&
make HOST=$SORTIX_PLATFORM initrd
If you want a copy of the kernel and initrd in the current directory (rather
than normally finding them in builds/ and sysroot/), you can run:
cd ~/sortix &&
make HOST=$SORTIX_PLATFORM sortix.bin sortix.initrd
You now have a sortix.bin and sortix.initrd pair. You can boot Sortix using a
multiboot bootloader by passing them as a multiboot kernel and multiboot
module/initrd.
If you have xorriso and grub-mkrescue from GRUB 2 installed, then you can
can build a bootable .iso by typing:
cd ~/sortix &&
make HOST=$SORTIX_PLATFORM sortix.iso
This will produce a ~/sortix/sortix.iso file that is bootable on real hardware
and virtual machines. Alternatively, you can take the sortix.bin file and boot
that with GRUB as a multiboot kernel and sortix.initrd (snapshot of the sysroot)
as a multiboot module/initrd.
This will produce a sortix.iso file that is bootable on real hardware and
virtual machines. This works by first building Sortix system and packaging up an
initrd, then it create a cdrom image with a bootloader configured to load the
kernel and initrd stored on the cdrom.
You can clean the source directory fully:
