Cross-compiler for my-kernel project

See my-kernel

This project is made to build a docker image for building a GCC-Cross-Compiler producing binaries in the i386-elf format, regardless of the platform on which you are working.

Usage

If you want to build this image

docker build -t i386-elf-compiler .

Note : obviously you can change the tag (-t option) by anything you want.

And if you want to run it here is a sample bash script to run this container.

#!/bin/bash

docker run  --tty                             \
            --interactive                     \
            --rm                              \
            --name dev-kernel                 \
            --volume /home/js/my-kernel:/tmp  \
            cross-compiler:latest

Note : In this example, the ran container mounted a folder into the container's /tmp, as it is an ephemeral container, this is enough for building your binaries.

Docker Image

This image can be cut in steps :

• Prepare the build by installing all needed packages
• Download binutils and gcc sources
• Build and install the new version of binutils
• Build and install the new version of gcc

Specifications
