Build system – Setup Linux

  1. Install git , to conveniently download the source code, and your distro's default build tools metapackage to do the cross-compilation process
  2. Some feeds might not available over git but only via subversion (short: svn) or mercurial. If you want to obtain their source-code, you need to install svn and mercurial as well
  3. Install other prerequisite packages, as indicated in the table and examples below
  4. Set (or unset) proper environment variables:
    • SED should not be set. If it is, run `unset SED` before compiling. (See Ticket 10612.)
    • GREP_OPTIONS should not have –initial-tab or other options affecting its output

Table of known prerequisites

This table contains the package name for each build prerequisite in different GNU/Linux and Unix like distributions.

  • Python on current Debian/Ubuntu distributions is Python 3 and Python 2 is required for the build system (May 2018). It typically may be installed as the python2.7-dev meta-package (or later version, if available).
  • Bleeding edge distros like Archlinux may fail to build base-files if Cryptographically signed package lists in Global build settings is enabled

Unfortunately not all dependencies are checked by make config, especially for packages.
You may encounter compile errors because you need a specific library in your system, and the only way is to search the missing library from the compiler error log and see what package contains it in your own distro.
The following table is a partial list of such dependencies:

Downloading Sources

clone the Git repository using one of the following commands.
:!: Do everything as normal user, don't use root user or sudo!
:!: Do not download sources in a directory that has spaces in its parent folders or full path!

Master or HEAD (main development tree)

The development branch contains the latest additions to OpenWrt, may have experimental or unstable code.

git clone https://git.openwrt.org/openwrt/openwrt.git

Note that the LEDE git reference https://git.lede-project.org/source.git, which may be found in posts and other references, presently redirects to the above URL.

Additional packages can be found in several feeds (Luci, packages, routing, management etc.). The build system will clone the correct feeds later when you update the package feeds.

Build stable release

See Details at selecting_a_specific_major_revision Select a stable release (example 19.07.3) by

git fetch --tags
git tag -l
git checkout v19.07.3
