meta-openembedded

The meta-openembedded repository is a collection of supplemental layers designed to extend the OE-Core universe with additional packages. Because this repository contains multiple distinct layers, each layer is managed by a designated maintainer and may have its own specific configuration, dependencies, and usage guidelines.

To use a specific feature or package, you must navigate to the relevant subdirectory and consult its specific README.md for instructions on how to include that layer in your BitBake configuration.

The meta-networking layer serves as a centralized location for networking-related packages and configurations. It is designed to be used directly on top of oe-core and complements the meta-openembedded collection.

Key use cases include:

• Building small networking devices (e.g., home routers, bridges, or switches).
• Adding network services to existing devices (e.g., small FTP/TFTP servers).

The meta-perl layer provides commonly-used Perl-related recipes, specifically focusing on Perl libraries found in the Comprehensive Perl Archive Network (CPAN).

Key packages include:

• libdbi-perl: The Perl DBI (Database Interface) module, which provides a consistent database access interface independent of the specific database engine.
• libdbd-sqlite-perl: A Perl DBI driver for SQLite that includes the entire distribution, allowing for a fast, transaction-capable RDBMS without additional dependencies.

The meta-webserver layer provides support for building web servers, web-based applications, and related software within the OpenEmbedded ecosystem.

Layer Layout

• recipes-httpd/: Web servers
• recipes-php/: PHP applications
• recipes-support/: Miscellaneous support recipes
• recipes-webadmin/: Standalone web administration interfaces

The meta-oe layer depends on openembedded-core.

The luajit recipe requires the host compiler to be capable of generating 32-bit code when the target architecture is 32-bit (e.g., ARM). You must ensure that $CC -m32 is functional on your build host. Depending on your host distribution, you may need to install specific multilib packages.

# For Arch Linux based distributions
pacman -S lib32-gcc-libs lib32-glibc

# For Ubuntu
sudo apt-get install gcc-multilib linux-libc-dev:i386

To use the meta-python layer, your build environment must include the following dependencies:

1. openembedded-core (the meta layer)

   • URI: git://git.openembedded.org/openembedded-core
   • Branch: master

2. meta-openembedded (the meta-oe layer)

   • URI: git://git.openembedded.org/meta-openembedded
   • Branch: master

The modphp recipe is no longer provided directly by this layer; instead, mod_php is built as part of the php recipe located in the meta-oe layer.

Because mod_php requires apache2 (which is provided in meta-webserver), and recipes in meta-oe cannot depend on meta-webserver, mod_php is not enabled by default. To use it, you must manually add apache2 to the PACKAGECONFIG variable for the php recipe in your configuration.
