## Object Operating System
## Install dependencies
#### Ubuntu
```sh
sudo apt update -y
sudo apt -y install build-essential binutils nasm xorriso grub-common qemu-system-i386 mtools
```
Need build GCC cross compiler for i686 architecture to compile project sources.
Refer to GCC documentation for detailed information - <https://gcc.gnu.org/install/>
## Build and run
Before build the project set some variables - DEBUG and GCC_PATH.
These variables may pass through *make* command `make *variables* *rule*`, or usage environment variables `export *name*=*value*`.
#### Variables
1. DEBUG. Takes a boolean value (true or false). Responsible for the debug version of the project to test it via DGB.
2. GCC_PATH. Takes the path to the GCC library of the cross-compiler you built earlier.
#### Ubuntu

```sh
make all
```
Build and run debug version
```sh
make DEBUG=true all
