Frosk is an operating system for x86-64/AMD64. It was also designed to eventually support 32-bit x86 but that is not fully built out nor tested (after all, 64-bit mode isn't even fully tested or working).
You must have gcc, make, nasm and ar (provided usually by binutils)
in order to build a Frosk disk image. Then just init the submodules and run make and everything
should go hunky dory:
git submodule init
git submodule update
makeIf make is giving you trouble make sure
you are using GNU make (gmake). You probably can't use clang as of now
because it doesn't have a builtin for the floor/ceil functions which I rely
on to implement those in the C standard library (I was lazy), but you can give
it a try by setting the CC and LD variables in config.mk.
If you are trying to build Frosk on a system that isn't x86-64/AMD64, you will
need to install or build a cross compiler, a version of gcc that will target
x86-64. With brew, you can install x86_64-elf-gcc and then set the
following values in config.mk:
CC := x86_64-elf-gcc
LD := x86_64-elf-gcc
AR := x86_64-elf-ar
HOST_CC := gcc
HOST_LD := gccIf you are installing a different cross compiler or building your own update config.mk following the above template. Note that you will also need a cross-platform version of ar.
The built disk image is a raw disk image, meaning it can be directly written to
a disk or partition with dd. You can run it easily in qemu with the
./test script.
I don't expect it will support many types of hardware very well, this isn't the most tested operating system lol. If you try to run it on hardware, let me know what you get out of it (good or bad!).
[This is a bit outdated— perhaps all philosophies are, but especially one invented as a joke by my younger and ultimately immature self, but I have preserved it for posterity's sake. If there is any philosophy true of Frosk, it is just that I could and wanted to build it so I did.]
The frosk philosophy aims for tranquility and mediation, to be one with the source and find peace in bytes. Yet frosk, and its philosophy, are human constructions, and as a result are inherently flawed, yet acceptance and minimization of these flaws are what admirable goals we adhere too.
Whilst we do not deny the usefulness of optimization, it is not a high priority for the frosk project, nor is pessimization. In fact, with regard to the typical question of "Is the glass half full, or half empty?", we answer neither with the positive nor with the negative, for the glass is neither half full nor half empty; indeed, if you want a glass, you should implement it first.
