Can't build per instructions

[gulfpearl]

I've followed the instructions and at the bundle install stage it aborts with the following:

  current directory: /home/app/.rvm/gems/ruby-2.6.3/gems/puma-3.12.2/ext/puma_http11
/home/app/.rvm/rubies/ruby-2.6.3/bin/ruby -I /home/app/.rvm/rubies/ruby-2.6.3/lib/ruby/2.6.0 -r
./siteconf20191227-20873-sq82em.rb extconf.rb
checking for BIO_read() in -lcrypto... *** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers.  Check the mkmf.log file for more details.  You may
need configuration options.

Provided configuration options:

To see why this extension failed to compile, please check the mkmf.log which can be found here:

  /home/app/.rvm/gems/ruby-2.6.3/extensions/x86_64-linux/2.6.0/puma-3.12.2/mkmf.log

extconf failed, exit code 1

Gem files will remain installed in /home/app/.rvm/gems/ruby-2.6.3/gems/puma-3.12.2 for inspection.
Results logged to /home/app/.rvm/gems/ruby-2.6.3/extensions/x86_64-linux/2.6.0/puma-3.12.2/gem_make.out

An error occurred while installing puma (3.12.2), and Bundler cannot continue.
Make sure that `gem install puma -v '3.12.2' --source 'https://rubygems.org/'` succeeds before bundling.

In Gemfile:
  puma

The only thing I did different than the instructions was the following, because it wouldn't work without giving user app sudo powers:

rvm autolibs disable
rvm requirements

[gulfpearl]

I got past that problem, I had to do:

apt install autoconf bison build-essential libssl-dev libyaml-dev libreadline6-dev zlib1g-dev libncurses5-dev libffi-dev libgdbm5 libgdbm-dev

and reinstall ruby as the app user. This should be added to the instructions.

Follow the installation instructions and everything installs correctly.

There is an updated video instruction on how you can install opendax and it's available right here:
