Build system – Installation

The build system works on Linux, BSD or MacOSX operating system. A case-sensitive filesystem is required.

It is recommended that you use a Linux distribution (for example Debian), either a standalone installation or one running in a virtual environment (Virtualbox, VMware or Qemu).

Ubuntu under Windows Subsystem for Linux is not an officially supported environment, but it appears to produce good builds. Cygwin(Windows) is NOT supported because the file system isn't case-sensitive.

Prerequisites

To generate a flashable firmware image file with a size of e.g. 8MB, you need:

  • ca. 200 MB of hard disk space for the build system
  • ca. 300 MB of hard disk space for the build system + package feeds
  • ca. 2.1 GB of hard disk space for source packages downloaded during build from package feeds
  • ca. 3-4 GB of available hard disk space to build (i.e. cross-compile) and generate the firmware file
  • ca. 1-4 GB of RAM are needed for the compilation stage.(4GB of RAM are required for compilation of x86 firmwares)

Install procedure on 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.

Note that 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).

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 LEDE, may have experimental or unstable code.

git clone https://git.lede-project.org/source.git

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.

17.01 branch

The “lede-17.01” branch contains the baseline code for version 17.01 and the individual releases (17.01.1, 17.01.2 etc). This branch is intended to contain stable code with carefully selected fixes and updates backported from the development branch.

To use this branch, you should first clone the Git repository using the git clone command shown above. Then move to the branch by using the git checkout command.

git checkout lede-17.01

:!: When changing branches, it is recommended to perform a throughout scrub of your source tree by using the make distclean command. This ensures that your source tree does not contain any build artifacts or configuration files from previous build runs.
