This is an experimental spin-off / distribution of ToaruOS which includes no third-party components.
The bootloader is a simple El Torito "no-emulation" CD bootloader. It is not guaranteed to work on real hardware, but has been tested in QEMU, Bochs, and VirtualBox.
The userspace includes a work-in-progress C standard library, the ToaruOS native libraries, the compositor (using only in-house graphics routines), and various other first-party utilities and applications.
You'll need a working compiler to build the gcc cross-compiler targeting
i686-pc-toaru. You will also need
yasm for some assorted assembly files I was too lazy to translate to gas.
xorriso is needed to build the final CD,
genext2fs (with Debian patches) is needed for the ramdisk. Python is needed for some parts of the build as well.
Install the toolchain:
ToaruOS's kernel is entirely in-house. Its userspace, however, is built on several third-party libraries and tools, such as the Newlib C library, Freetype, Cairo, libpng, and most notably Python. While the decision to build ToaruOS on these technologies is not at all considered a mistake, the possibility remains to build a userspace entirely from scratch.
To support building the native ToaruOS libraries and port some basic software, a rudimentary C library is required.
Cairo is a major component of the modern ToaruOS compositor, but is the only significant third-party dependency. This makes the compositor, which is a key part of what makes ToaruOS "ToaruOS", an important inclusion in this project. Very basic work has been done to allow the compositor to build and run without Cairo, but it is a naïve approach and remains very slow. Implementing Cairo's clipping and SSE-accelerated blitting operations is a must.
Support for TrueType/OpenType TBD, but vector fonts are critical to the visual presentation of ToaruOS.
ToaruOS used a lot of PNGs, but maybe writing our own format would be fun.
Enough C to port the dynamic loader. (Done)
Get the VGA terminal building. (Done)
Get the shell running. (Done)
De-Cairo-tize the compositor. (Done, but more work planned)
Enough C to port Python. (In progress)
Enough C to port GCC. (In progress)
