echidnaOS is an attempt at creating an operating system from scratch. The kernel is written primarily in C, with some assembly here and there.

Please, follow these instructions to build a bootable IMG of echidnaOS. You can then write the resulting image to a Hard Drive.

• nasm
• gnu make
• gcc
• g++
• bison
• qemu (for testing the image, non essential)

You can install all the above packages on Ubuntu/Debian with the following commands:

sudo apt-get update
sudo apt-get install nasm build-essential qemu-system-x86

Make sure you are in the root of the source tree.

Now let's build the cross toolchain:

make tools

This step will take a while, especially on slower systems.

You can now use:

make clean-tools

To remove build files and sources that aren't needed anymore.

Now that every requirement is satisfied, let's build the kernel, the shell, and create the image:

make

If make didn't error, congratulations, you managed to build echidnaOS. There should be a bootable "echidna.img" image in the project's root now.

You can test the image in qemu with:

qemu-system-i386 echidna.img
