Trying to start rails server

Question

I've cd in app root directory, and ran rails s. Then I get the error:

Could not find gem 'rbczmq' in any of the gem sources listed in your Gemfile or available on this machine.

Installing the gem manually, with gem install rbczmq , had no success because of this:

ERROR: Error installing rbczmq: ERROR: Failed to build gem native extension.

 /home/iulian/.rvm/rubies/ruby-2.3.1/bin/ruby extconf.rb 

"./autogen.sh" autogen.sh: error: could not find libtool. libtool is required to run autogen.sh. ZeroMQ autogen failed! * 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.

Then, I presumed that it needs libtool . I've tried to install it but it prompted that it is installed under the most recent version. I've search lastly that file, mkmf.log under the path ~/.rvm/gems/ruby-2.3.1/gems/rbczmq/ext/mkmf.log but with no success. In the others installed gems directories this file exists, so I suppose that I don't find it in this problematic gem because it hasn't finished installing.

This app is programmed using rails 4, and I am trying to run it using Rails 5. This is also the Gemfile:

source 'https://rubygems.org'

gem 'rails'
gem 'sqlite3'
gem 'tzinfo-data'
gem 'rbczmq'
gem 'iruby'
gem 'spring', group: :development

gem 'elasticsearch-persistence', :require => 'elasticsearch/persistence'

Which could be the problem and how could I solve it?

Answer 1

I had this problem once. Do this

sudo apt-get install libgmp-dev

or

sudo apt-get install libgmp3-dev
