Building sanos under sanos

In this video you can see sanos building itself. First it boots in the QEMU emulator. The more /proc/info command shows that the sanos kernel has been built using the Microsoft C compiler (MSVC). The source code for Sanos is located in /usr/src and this directory contains the master makefile for sanos. The make install command builds all the sanos components:

C runtime library (/usr/lib/libc.a)
Assembler, C compiler, and other build tools (/usr/bin/*.exe)
Boot sector (/boot/boot)
Secondary boot loader (/boot/osldr.dll)
Sanos kernel (/boot/krnl.dll)
Device drivers (/boot/*.sys)
OS API module (/boot/os.dll)
Command line utilities (/bin/*.exe)

After the all the components have been built, sanos is rebooted, and you can now see that the new kernel has been built using the Sanos C compiler (TCC).
