Installing Erlang, Rebar3 and Lisp Flavoured Erlang (LFE)

Support

Hello,

Requirements:

I have Searched the forum for my issue and found nothing related or helpful
I have checked the Resources category (Resources Index)
I have reviewed the Wiki for relevant information
I have read the the Release Notes and Errata

OpenMandriva Lx version:

OpenMandriva Lx release 6.0 (Vanadium) Rock for x86_64

Desktop environment (KDE, LXQT…):

KDE Plasma Version (Wayland): 6.3.4

Description of the issue (screenshots if relevant):

When searching the repos for erlang, I could only find

 erlang-rpm-macros.noarch : Macros for simplifying building of Erlang packages

Running erl would only result in Would you like to install erlang-base(contrib) y/N. Typing y then hitting Enter would do nothing and return me to the next prompt.

After further searching in the forums, I found an article discussing using abb to install applications. The following is what I did to get Erlang (OTP 25), Rebar3 and LFE installed.

Relevant informations (hardware involved, software version, logs or output…):

This was a newly installed OMLx 6.0, with Java 17 and NetBeans and ECL just installed.

Hardware: (Dell Precision 5530)

1. Install Erlang

Step 1: Install relevant software

$ sudo dnf install git abb
$ abb clone erlang

Step 2: Attempt the build and install any other required packages

$ abb build erlang

At this point abb will let you know about any missing dependencies. Repeat this step until abb stops complaining. Please note I had java-17-openjdk-devel et. al. installed prior. In my case these were the missing dependencies.

$ sudo dnf in -y bison flex java-rpmbuild pkgconfig tcl-devel unixODBC-devel valgrind-devel wxgtkc3.2-devel lib64gd-devel libcurl-devel libcurl4 wxwidget

Step 3: After a successful build, install the newly minted RPM(s).

$ cd RPMS/x86_64 # where the output of the builds are, aka the RPMs
$ sudo dnf in erlang-base-<version>.rpm # Use [TAB] for autocomplete
$ erl # Test that you have a working version of Erlang.

2. Install Rebar3

Things get a bit more involved here.

$ abb clone erlang-rebar3

Update the erlang-rebar3.spec file to the version of rebar3 that works with the OTP version installed in the previous section. As of this writing, it was OTP 25, so I changed the version to 3.24.0 and removed the %mkrel token.
Also update the Source0 to download the .zip or tar.gz file from GitHub.

$ abb build erlang-rebar3
$ cd erlang-rebar3/RPMS/x86_64 # you will see the RPM with the rebar3 version you selected.
$ sudo dnf in -y erlang-rebar3-[TAB] # too long to write it out and your version may vary...
$ rebar3 version # test that rebar3 was successfully installed.

3. Install Erlang-LFE

At this point, using the abb version of erlang-lfe was getting too complicated.

Easiest option at this point is to use the rebar3_lfe plugin. Follow the setup instructions found here, adding the plugin to ~/.config/rebar3/rebar.config.

$ mkdir -p $HOME/.config/rebar3
$ rebar3 lfe repl # Testing LFE

It hasn’t been built in a while:

Which means it probably needs an update, as well.

As will all the dependents, most likely:

Thanks for the update. I saw that as well, based on the Github dates. As a first time ABB user, it was fun learning, but it started getting a bit hairy towards the end. :sweat_smile:

What would maintaining this package entail? I don’t mind contributing if possible.

Fork the package repo in your GH account, update the version and apply any needed fixes or patches (and remove any broken ones), and submit a PR after you have a known good local build and can test the package is working. If you aren’t in the Cooker room on Matrix yet, that is a good place to get advice about packaging.

Great! Does that mean I need to be running Cooker or can I stick with Rock?

Because of how we release, packages need to be built and tested in Cooker. I think you can just set up a VM or chroot to handle that if you don’t want to daily drive it like some of us do.
