Error while installing Nitrogen

Question

while installing the nitrogen i had the following error. Following install instructions outlined in http://nitrogenproject.com/doc/tutorial.html, I pulled source from GitHub and ran the following command.

    msairam@passion:~/nitrogen$ make slim_yaws PROJECT=testproj

New to erlang. Can somebody help me? Thanks

Answer 1

This is definitely a problem with your Erlang installation -- the reltool application is probably missing.

One of the things that should be fixed in the Nitrogen docs is how to properly install Erlang. The current docs more-or-less assume Erlang is already installed.

The Erlang packages provided by Ubuntu/Debian are largely federated, meaning apt-get install erlang doesn't give you all of Erlang - there are a bunch of missing applications there.

Instead, I usually recommend downloading and installing the packages prepared by Erlang Solutions: https://www.erlang-solutions.com/resources/download.html

Specifically, the esl-erlang package is complete erlang, while the erlang package is the federated package. If you're new to Erlang, or not sure which to install, esl-erlang is the safest choice one to install, which will ensure you get all of erlang.

NEW INSTRUCTIONS

Install the packages as follows:

wget http://packages.erlang-solutions.com/erlang-solutions_1.0_all.deb
sudo dpkg -i erlang-solutions_1.0_all.deb
sudo apt-get update
sudo apt-get install esl-erlang

END NEW INSTRUCTIONS

Either that, or installing Erlang from source using the typical configure && make && make install pattern. http://www.erlang.org/downloads

Once done, try re-running make slim_yaws PROJECT=testproj within Nitrogen.

Answer 2

I installed erlang version 18.3 from https://www.erlang-solutions.com/resources/download.html. Similarly i downloaded the nitrogen and used the instruction as given in http://nitrogenproject.com/doc/index.html#sec-3.

For time being i am using the embed option and using nitrogen.

Is there any other solution?

Answer 3

i have installed Ubuntu 16.04 (Xenial Xerus).
