An open-source, hobby/research kernel and operating system.

Zylix provides a script known to work under WSL and Ubuntu to download and compile a toolchain. Run tools/toolchain/build.sh. Required programs, and steps to follow if the script breaks on your system are there.

By default, the build scripts and Makefiles generate x86_64 binaries. To change the target architecture just change references of x86_64-pc-zylix to i686-pc-zylix for 32-bit builds. Automatic toolchain support for more architectures is coming but I'm sure it's possible to whip up an unpatched cross compiler for any architecture.

To build Zylix and the toolchain the following software packages must be present in your system.

binutils (2.28 confirmed working)
gcc (7.1.0 confirmed working)
genext2fs (1.4.1 confirmed working) for hard disk image creation.
grub 2.0 for grub-mkrescue.
patch, wget, tar and GNU make for auto toolchain script.
cdrkit
xorriso
mkisofs

You can edit the arguments passed to the emulator in the top level Makefile. Some sample choices for different machines are listed below.

i386:
qemu-system-i386 -kernel ./sysroot/boot/zykernel -m 1024 -k en-us -show-cursor -vga std -net nic,model=rtl8139 -net user -rtc base=localtime

Raspberry Pi (Models 1 to 3):
qemu-system-arm -kernel ./sysroot/boot/zykernel -cpu arm1176 -m 256 -M raspi -serial stdio
