Erlang.mk requires GNU Make to be installed. While it will
currently work with GNU Make 3.81, support for this version
is deprecated and will be removed in the future. We recommend
GNU Make 4.2 or later (especially if you want to benefit
from parallel builds via the -j flag).
Git and Erlang/OTP must also be installed.
Erlang.mk supports the current Erlang/OTP release and the two releases before it. For example, when Erlang/OTP 29 is the latest release, the supported releases are Erlang/OTP 29, 28, and 27.
Some functionality requires that Autoconf 2.59 or later be installed, in order to compile Erlang/OTP. Erlang/OTP may have further requirements depending on your needs.
Some packages may require additional libraries.
The commands to install packages vary between distributions:
Arch Linux.
$ pacman -S erlang git make
Alpine Linux and other distributions based on BusyBox come
with an incompatible awk program. Installing the GNU Awk
(gawk on Alpine) solves this issue.
Parallel builds may require the program flock that can
be found in the package util-linux.
FreeBSD comes with binary and source packages:
Install binary packages.
$ pkg install erlang git gmake
On FreeBSD the make command is BSD Make. Use gmake instead.
While Apple distributes their own GNU Make, their version is very old and plagued with numerous bugs. It is recommended to install a more recent version from either Homebrew or MacPorts:
Homebrew.
$ brew install erlang git make
Homebrew installs GNU Make as gmake. The make command
is the one provided by Apple.
MacPorts.
$ sudo port install erlang git gmake
Parallel builds may require the program flock which can
be installed via Homebrew or manually. The instructions
to install are available from its repository:
https://github.com/discoteq/flock
Erlang.mk can be used on Windows inside an MSYS2 environment. Cygwin, MSYS (the original) and native Windows (both Batch and PowerShell) are currently not supported.
Note
Erlang.mk expects Unix line breaks in most of the files (LF instead of CRLF). Make sure to configure your text editor adequately.
The rest of this section details how to setup Erlang/OTP and MSYS2 in order to use Erlang.mk.
Erlang.mk requires Erlang/OTP to be installed. The OTP team provides binaries of Erlang/OTP for all major and minor releases, available from the official download page. It is recommended that you use the 64-bit installer unless technically impossible. Please follow the instructions from the installer to complete the installation.
The OTP team also provides a short guide to installing Erlang/OTP on Windows if you need additional references.
You can install Erlang/OTP silently using the /S switch
on the command line:
C:\Users\essen\Downloads> otp_win64_29.0.exe /S
The only supported environment on Windows is MSYS2. MSYS2 is
a lightweight Unix-like environment for Windows that comes
with the Arch Linux package manager, pacman.
Install it from msys2.org and follow the post-install update steps on that site. The default install path is C:\msys64.
After following these instructions, you can install GNU Make,
Git and any other required software. From an MSYS2 shell,
you can call pacman directly:
$ pacman -S git make
You can use pacman -Ss to search packages. For example,
to find all packages related to GCC:
$ pacman -Ss gcc
If you are going to compile C/C++ code, you will need to install this package, as Erlang.mk cannot use the normal "gcc" package:
$ pacman -S mingw-w64-x86_64-gcc
You can also run commands under the MSYS2 environment from the Windows command line or batch files. This command will install GNU Make and Git:
C:\> C:\msys64\usr\bin\bash -lc "pacman --noconfirm -S git make"
You can use similar bash commands if you need to run programs
inside the MSYS2 environment from a batch file.
