## Building
There does not exist a complete list of needed packages for building. From the top of my head I can say that *cmake*, *ninja*, *make*, *grub*, *rsync* and emulator (*qemu* or *bochs*) are needed.
### Needed packages
You need cmake version of atleast 2.26. If you are using cmake that is not found from PATH, you can set the CMAKE\_COMMAND environment variable to point to the correct cmake binary.
#### apt (tested on ubuntu 22.04)
```# apt install build-essential git ninja-build texinfo bison flex libgmp-dev libmpfr-dev libmpc-dev parted qemu-system-x86```
> ***NOTE:*** You need cmake version of atleast 2.26. If you are using cmake that is not found from PATH, you can set the CMAKE\_COMMAND environment variable to point to the correct cmake binary. Or you can let build script download correct version of cmake if you don't have one.
When you clone this reposity, make sure to also clone submodules. This can be done by cloning with the command ```git clone --recurse-submodules https://git.bananymous.com/bananymous/banan-os.git``` or if you have already cloned this repo, run ```git submodule init && git submodule update```.
To build the toolchain for this os. You can run the following command.
> ***NOTE:*** The following step has to be done only once. This might take a long time since we are compiling binutils and gcc.
