FROST is a 32-bit operating system based on a microkernel. It is written entirely in FreeBASIC and Assembly.

• fbc, tested with 1.05.0 (the FreeBASIC compiler, available on freebasic.net)
• nasm, tested with 2.11.08 (the Netwide Assembler, available on nasm.us)
• GNU make, GNU assembler and the GNU linker

To build the kernel, you can type "make" in the "kernel" directory. You will then get a file called "frost.krn" which is the kernel. Building the init-process is very similar. If you want to get a full iso with grub2 and a menu, type "./build_iso.sh" in the "build"-directory. You will then get a file called "frost.iso" which is the iso-image. On some Linux distributions the script will fail because they contain genisoimage from cdrkit instead of mkisofs from cdrtools. You can create a link on genisoimage named mkisofs, but I strongly recommend installing cdrtools instead of cdrkit. If cdrtools is not available on your distribution, please contact its maintainers (I don't want to get into a debate here, but cdrkit received it's last commit three years ago).
