As of now, you'll only be able to build and run bfboot from within the build directory. To build it, simply run 'make' in the root of the source tree. bfboot depends on nasm at runtime, so make sure to have that installed and in your $PATH.

Simply run ./bfboot within the bfboot source tree. bfboot takes 2 arguments, namely the brainfuck source file and the output name of the created bootable image.

Example: ./bfboot 99bottles.bf 99bottles.img

The generated image is a flat disk image. It can be written to a USB stick using utilities such as cat or dd, or it can be run in an emulator such as QEMU.

To run in QEMU: qemu-system-i386 -hda 99bottles.img
