Yet Another Free Operating System WHAT IS YAFOS YAFOS (Yet Another Free Operating System) is a free open source kernel maintained by a large community (currently at maximum two active people ;)). The goals at this stage are specificly to build a multitasking OS wich supports multiple processor cores and the 64 bit intel architecture. (Yeah... hopefully it will. Until then it's just fun to write this ;)) If you need any information, take a look at the doc/ directory or write an email to me.

CURRENT STATUS TODO? INSTALL THE TOOLCHAIN Currently the own toolchain is disabled (but functional). Skip this paragraph if you want. YAFOS has it's own toolchain to provide independency from gcc updates. (They may do harm. TODO make some research on using more of the options given by an own compiler.) You may compile a crosscompiler using: make cc32 This will do everything automatically. If it fails, see that all needed software is installed (lists for some distributions in the makefile) and retry after doing rm -R /tmp/ct-ng since there may be temporary files saved which may block the installation process. The script will create a working directory in your home directory ~/cc If this already exists it will append 'c' until it doesn't. It should remove it automatically but that's not guaranteed! Feel free to delete it manually, it has no use after building the toolchain. Be sure to install qemu before trying to test. Alternatively you can create an ISO with grub and the kernel and reboot everytime you want to test. Have fun! BUILD Be sure to read and follow the instructions given in [INSTALL THE TOOLCHAIN] Just execute 'make run' to compile the kernel and start the qemu emulator. Qemu may be interfaced with gdb via the command: target remote localhost:1234 Be sure to take a look at the switches provided in kernel/settings.h CONTRIBUTING To open all project files we have an editor independend project file. (Yes, it's a bash script that just executes your favorite editor with all the files) Be sure that your editor supports tabs or so - else you'll get a lot of windows. (And who wants windows...)
