HOWTO

1. Set up a cross-compile toolchain for powerpc-eabi.
   For an example, see http://www.ifp.illinois.edu/~nakazato/tips/xgcc.html

   !!!! NOTE !!!!
   Make sure to configure gcc with --with-float=soft or running the kernel will cause endless "Floating Point Unavailable" exceptions

2. Download the project somewhere, e.g. ~/projects/ppcOS/

3. Install Virtutech Simics, and create a new workspace in ~/projects/simics-ppc/

4. Extract the newlib package somewhere on your machine

5. Create a build directory for newlib, e.g. ~/projects/newlib/

6. cd ~/projects/newlib/

7. /path/to/newlib/configure --target=powerpc-eabi --prefix=~/projects/ppcOS/newlib --disable-newlib-supplied-syscalls --with-float=soft

8. make

9. make install

10. cd ~/projects/ppcOS/

11. Build the kernel and boot loader with 'make all', and run it with 'make emu'
