Using supported package formats

The main goal of most of Poky's tasks is to produce packages. The other tasks use built packages to make other deliverables such as images and toolchains.

A recipe may generate one or more packages as a result of it being executed by BitBake; on the other hand, images and toolchains are made of several packages that are unpacked and configured to accomplish the intended goal. The generated result is wrapped in such a way that it can be installed into one or more images, or it can be deployed for later use.

List of supported package formats

Currently, BitBake supports four different package formats:

  • RPM: Originally named Red Hat Package Manager, but now known as the RPM package format since its adoption to several other Linux distributions, it is used by several popular Linux distributions such as SuSE, OpenSuSE, Red Hat, Fedora, CentOS, among others.

  • DEB: The Debian Package Manager is used by Debian and several other Debian-based distributions; the most widely...
