Razbit and Itara20's operating system, RazOS.

This is our diploma work, an operating system trying to be as UNIX-like as is possible in our timeframe. Maybe one day this project (Razos kernel and rlibc C library) is POSIX/C99 compliant, maybe.

#Setting up the developing environment ##Making cross-compiler Start by making sure you have GCC-5.2.0 installed. Then see the file cross-compiler for a quick how-to build a cross-GCC.

http://wiki.osdev.org/Building_GCC http://wiki.osdev.org/GCC_Cross-Compiler

##Setting up NASM

$ sudo apt-get install nasm

##Setting up Bochs First, download Bochs sources (we use version 2.6.8). Make sure you have libgtk2.0-dev, libncurses5-dev and libsdl-dev (SDL 1) libraries.

Extract the tarball and cd to the bochs-2.6.8 directory. Then build Bochs:

$ ./configure --enable-smp \
              --enable-cpu-level=6 \
              --enable-all-optimizations \
              --enable-x86-64 \
              --enable-pci \
              --enable-vmx \
              --enable-debugger \
              --enable-disasm \
              --enable-debugger-gui \
              --enable-logging \
              --enable-fpu \
              --enable-3dnow \
              --enable-sb16=dummy \
              --enable-cdrom \
              --enable-x86-debugger \
              --enable-iodebug \
              --disable-plugins \
              --disable-docbook \
              --with-x --with-x11 --with-term --with-sdl
$ make
$ sudo make install

#Building and running Building the whole thing is simple, just run make

###Build the kernel

$ make kernel

###Build the rlibc and user-space

$ make tools
$ make init

##Run Running the system requires root priviledges (see scripts update_image.sh and run_bochs.sh for more info)

To run Razos using Bochs

$ sudo make bochs

Or using QEMU

$ sudo make qemu

###Debugging in Bochs See http://wiki.osdev.org/Bochs#Bochs_debugging_facilities
