# OpenPOWER Firmware Build Environment

The OpenPOWER firmware build process uses Buildroot to create a toolchain and

build the various components of the PNOR firmware, including Hostboot, Skiboot,

OCC, Petitboot etc.

## Building an image

To build an image for a Blackbird system:

```

git clone --recursive https://github.com/open-power/op-build.git

cd op-build

./op-build blackbird_defconfig && ./op-build

```

There are also default configurations for other platforms in

`openpower/configs/`. Current POWER9 platforms include Witherspoon,

Boston (p9dsu), Romulus, and Zaius.

Buildroot/op-build supports both native and cross-compilation - it will

automatically download and build an appropriate toolchain as part of the build

process, so you don't need to worry about setting up a

cross-compiler. Cross-compiling from a x86-64 host is officially supported.

The machine your building on will need Python 2.7, GCC 8.4 (or later), and

a handful of other packages (see below).

### Dependencies for *64-bit* Ubuntu/Debian systems

1. Install Ubuntu 22.04 or Debian 12 (x86_64 or ppc64le).

2. Enable Universe (Ubuntu only):

        sudo apt-get install software-properties-common

        sudo add-apt-repository universe

3. Install the packages necessary for the build:

        sudo apt-get install cscope universal-ctags libz-dev libexpat-dev \

          wget bc rsync

### Dependencies for *64-bit* Fedora systems

1. Install Fedora 33 (x86_64 or ppc64le).

2. Install the packages necessary for the build:
