I’ve been reading The little book about OS development and wiki.osdev.org and took some notes along the line. Here’s what I wrote on environment setup.

Environment setup

You’ll need a cross compile toolchain consisting of GNU Binutils and gcc. The osdev wiki has a great page on setting up a cross compilation toolchain.

It took me a few times because I didn’t read the instructions properly. It is important to unpack the sources for binutils and gcc and have separate build directories, gcc-4.2 and gcc-build for example. Then, for building gcc, make sure the newly built binutils are on your path.
