# banan-os
|
|
This is my hobby operating system written in C++. Currently runs on x86 based architectures (32 and 64 bit). Currently this operating system supports ext2 filesystem, ata drives (pio mode), vesa/vbe graphics mode and multithreaded processing.

## Building
|
|
> **_NOTE:_** I will be using ninja in these build instructions but you may use any other buildsystem cmake supports. If you want to use ninja, you can either define a environment variable 'CMAKE_GENERATOR=Ninja' or pass '-G Ninja' to all commands invoking cmake.
|
|
|
|
Create the build directory and cofigure cmake
|
|
```sh
|
|
mkdir build
|
|
cd build
|
|
cmake ..
|
|
```
|
|
|
|
|
|
|
|
> **_NOTE:_** The following step has to be done only once. This might take a long time since we are compiling binutils and gcc.
|
|
|
|
To build the toolchain for this os. You can run the following command.
|
|
```sh
|
|
ninja toolchain
|
|
cmake --fresh .. # We need to reconfigure cmake to use the new compiler
|
|
ninja libstdc++
|
|
```
|
|
|
|
|
|
|
|
To build the os itself you can run either of the following commands. You will need root access since we need to mount the disk image to install grub.
|
|
```sh
|
|
ninja qemu
|
|
ninja bochs
|
|
```
|
|
|
|
|
|
|
|
You can also build the kernel or disk image without running it:
|
|
```sh
|
|
ninja kernel
|
|
ninja image
|
|
```
|
|
|
|
|
|
|
|
If you have corrupted your disk image or want to create new one, you can either manually delete _banan-os.img_ and cmake will automatically create you a new one or you can run the following command.
|
|
```sh
|
|
ninja image-full
|
|
```
