can't bundle install json gem in ubuntu

Question

I have installed ruby on rails using rvm . I am trying to bundle install an older project that I had on a former pc but I get the following error when I run the bundle install command:

Installing json 1.8.3 with native extensions

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

    /home/florin/.rvm/rubies/ruby-2.2.3/bin/ruby -r ./siteconf20151003-5986-vme5ji.rb extconf.rb

Gem files will remain installed in /home/florin/.rvm/gems/ruby-2.2.3/gems/json-1.8.3 for inspection.
Results logged to /home/florin/.rvm/gems/ruby-2.2.3/extensions/x86_64-linux/2.2.0/json-1.8.3/gem_make.out
An error occurred while installing json (1.8.3), and Bundler cannot continue.
Make sure that `gem install json -v '1.8.3'` succeeds before bundling.

Reading the internet I tried installing all the dev things like :
sudo apt-get install libpq-dev

sudo apt-get install libmysqlclient-dev
sudo apt-get install libpq-dev
sudo apt-get install libsqlite3-dev
sudo apt-get install libev-dev

but it didn't work.

Solution

/usr/bin/ld: cannot find -lgmp means that the linker tries to link lgmp but can't find it.

Solution: Install the library needed: sudo apt-get install libgmp3-dev
