A shell script for building GCC and Binutils for use in OS Development. Based on the procedure detailed on OSdev Wiki
This script is made with GevOS in mind but should work on any Hobby OS with some tinkering.
You need to install the dependincies needed to compile GCC and Binutils, The table below contains package names in different distros.
| Debian | Arch | Fedora |
|---|---|---|
| build-essential | base-devel | gcc |
| bison | ... | bison |
| flex | ... | flex |
| libgmp3-dev | gmp | gmp-devel |
| libmpc-dev | libmpc | libmpc-devel |
| libmpfr-dev | mpfr | mpfr-devel |
| texinfo | ... | texinfo |
- clone the repo
git clone https://github.com/Edersteiner/CrossCompilerScript
- Then cd into the repo
cd CrossCompilerScript
- Run the script. It shouldn't need root priveleges.
./CCBuild.sh
You could also download the script from the releases tab and run it.
Now wait for everything to compile. GCC might take up to an hour, but it probably wont take that long.
When it's finished you have the cross compiler located at: $HOME/opt/cross/bin/$TARGET-gcc
you can verify that it compiled correctly by running:
$HOME/opt/cross/bin/$TARGET-gcc --version
By default, the Binutils version is 2.41 and the GCC version is 11.2.0
This is because those versions work the best with GevOS.
The default architecture is i686-elf.
All this can be changed at the top of the CCBuild.sh script if your hobby os needs a different or newer cross compiler.
If you have any problems you are welcome to post an Issue
