What we want

To install ELM on Freebsd


There is no port for ELM.

So we can't use

pkg install something


cd /usr/ports/lang/elm && make clean install


Install ELM from the source.


  • Having wget installed (if not => pkg install wget)

First step : Install Haskell/ghc

We need to install Haskell to compile the ELM sources.
The right version here is ghc 7.10.3 since the latest version cannot be used to install ELM v18

(Some of the following instructions have been retrieved from the great article on how to install ghc on freebsd :
N.B. : Some adpatations have been made to meet the ELM install

Install and configure gcc:

# Install compatibility package
$ pkg install compat8x-amd64
# Install gcc
$ pkg install gcc
# it gives you gcc6

Download ghc archive (size is 72.76M):

$ cd /tmp
$ wget

Extract archive

$ tar -xf ghc-7.10.3-x86_64-portbld-freebsd.tar.xz
$ cd ghc-7.10.3

Make install ghc

$ env CC=gcc6 ./configure --with-gcc=gcc6 --with-ld=/usr/local/bin/ld
$ gmake install

Check that ghc and Haskell are well installed:

$ ghc --version
The Glorious Glasgow Haskell Compilation System, version 7.10.3

$ runhaskell --version
runghc 7.10.3

Second step : Install CABAL

We need cabal to manage haskell packages (see

Install cabal package

$ pkg install hs-cabal-install

Third step : Build ELM from source

Create elm folder

$ mkdir -p /usr/local/elm
$ cd /usr/local/elm/

Get ELM source code

$ curl > BuildFromSource.hs

Run haskell to build ELM from source

$ runhaskell BuildFromSource.hs 0.18 
# about 10 minutes... (yes, that long)

Last step : Configure path

Change Path to PATH="$PATH:/usr/local/elm/Elm-Platform/0.18/.cabal-sandbox/bin"

Last check:

$ elm --version
