Cross-Compiler fun
I’ve been interested in OS development for a while, and now have a prototypical ARM OS on my private source tree. For that I used gcc-arm-embedded, which worked quite well. However, as time went on, i became interested in building my own tool chains. I started with this list of requirements
- An up-to-date C/C++ compiler, such as gcc or clang
- I prefer gmake
- On i386 I like nasm, but I’ll use gas if necessary
- I like ld, objcopy, etc from binutils
- The targets I prefer to cross compile from are OS X and FreeBSD. I prefer to cross-compile to i386, arm, sparc and mips targets
I ended up with two shell scripts, one for GCC/Binutils/Make and one for Clang/Binutils/Make, which download and install the latest GCC/Clang/Binutils and create a fully operational toolchain for the target of my choice. You can find them here:
