Thierry's own OS.
Rainbow is licensed under the BSD (Simplified) 2-Clause License.
To build Rainbow from your existing operating system, the following tools are required (version numbers show what I am using and do not indicate strict requirements):
1) binutils 2.27 (cross-platform tools)
2) gcc 6.3.0 (cross-platform compilers)
3) MinGW-w64 (i686-w64-mingw32 and x86_64-w64-mingw32 cross-compilers)
5) GNU Make 3.81
6) Python 3.4.3 (for configure script)
If you are unsure how to produce the required binutils and gcc cross-compilers, take a look here: http://wiki.osdev.org/GCC_Cross-Compiler.
There is also an easy to use Makefile here: https://github.com/kiznit/build-gcc-and-binutils
To generate an ISO image of Rainbow, you will also need:
6) grub-mkrescue 2.02
And finally if you want to run your iso image under an emulator, I use qemu:
7) qemu-system-xxx 2.6.50
| Description | Machine | Architectures |

-
Create a directory where you want the build to happen. I simply create a 'build' directory under the root of Rainbow:
mkdir build
-
Run the configure script from the build directory you just created. This will generate a Makefile in the current directory.
cd build ../configure
-
Create the OS image
make image
-
Run the image in the emulator
make run
-
Run tests
make test
