Build system setup

  1. Assuming a GNU/Linux environment, otherwise see alternative guides.
  2. Install Git to download the source code, and your distro's default build tools metapackage to do the cross-compilation process.
  3. You may also need to install Subversion (SVN) or Mercurial to fetch the source-code for some feeds which are not available over Git.
  4. Install other prerequisite packages, as indicated in the table and examples below.
  5. Unset environment variables like SED and GREP_OPTIONS and aliases/functions like which.

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

Note that the advice above may be somewhat outdated. E.g. python3 is currently the default in OpenWrt master, 22.03 and 21.02, while python2.7 has been removed due its end-of-life.

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:

Distribution-specific instructions.

Please note that OpenWrt master, 22.03 and 21.02 branches do not need python2.7 any more. Python3 should be your default.

Arch users may install the openwrt-devel meta-package from the AUR or alternatively, manually install the build dependencies as follows:

# Essential prerequisites
pacman -S --needed base-devel autoconf automake bash binutils bison \
bzip2 fakeroot file findutils flex gawk gcc gettext git grep groff \
gzip libelf libtool libxslt m4 make ncurses openssl patch pkgconf \

# Optional prerequisites, depend on the package selection
pacman -S --needed asciidoc help2man intltool perl-extutils-makemaker

Modernized set for Ubuntu 22.04 for OpenWrt master, 22.03 and 21.02 branches that do not need python2.7 any more. Python3 is installed by default in Ubuntu22.04.
