Download Erlang/OTP

The latest version of Erlang/OTP is 25.1.2. To install Erlang you can either build it from source or use a pre-built package.

Take a look at the Erlang/OTP 25 release description to see what changes Erlang/OTP 25 brings over the previous major version.

The Erlang/OTP version scheme is described in the Erlang/OTP Systems Principles Guide.

Compiling Erlang from source #

You can build Erlang from source on your own, following the building and installation instructions. In a nutshell to install a pre-built archive you need only do:

./configure && make && make install

If you clone the release from git, there may be some additional steps needed depending on which version of Erlang/OTP you are compiling. So always make sure to read the build and install instruction of the release you are compiling.

You can also use third-party tools such as Kerl or asdf to compile Erlang. They help to remove the differences between Erlang/OTP releases and the OS you are compiling on.

Pre-built Binary Packages #

Most OS package managers provide pre-built binary packages.

  • For Homebrew on macOS: brew install erlang
  • For MacPorts on macOS: port install erlang
  • For Ubuntu and Debian: apt-get install erlang
  • For Fedora: yum install erlang
  • For FreeBSD: pkg install erlang

The OS provided packages tend to not contain the latest version of Erlang/OTP. So Erlang Solutions provides up to date pre-built packages for the latest stable releases. Erlang Solutions provides pre-built binary packages for Ubuntu, Debian, Fedora, CentOS and other operating systems.
