Installation issue for Ubuntu 14.04.3 LTS

[Eric Gascoine]

I have found that there's another dependency that it required to build the nokogiri gem.

I needed to install the libgmp-dev package as well to satisfy the requirements for the extension build.

I'm using the 14.04 LTS with the kde-desktop, so I'm not sure if this was previously installed by default or by a dependency which is no longer there on my system.

-Eric.

How did you reach this conclusion? Can you please share your log files?

My personal laptop is Ubuntu 14.04 and I don't have this library installed, so I'm curious to see what's going on.

I ran into the same issue - also solved by installing libgmp-dev package - (thank you Eric !)

Here are a copy of my logs

Nokogiri has no direct dependency to libgmp. Possibly Ruby was compiled with gmp-support enabled? Do other gems build? "gem install ffi" for instance?

[Gerald Hofmaier]

Similar issue with atomic gem .

Ruby was compiled rvm.

Similar issue with atomic gem .

Ruby was compiled via rvm.

[Mike Dalessio]

Lars is absolutely correct, there's no dependency by nokogiri on libgmp. If this is coming from anywhere, it's coming from your ruby build.

Which, of course, begs the question of: how did this Ruby get built on your machine if this library wasn't installed?

Did you upgrade or reinstall your Linux distro and leave this version of Ruby hanging around in your ~/.rvm directory from before the upgrade?

[Gerald Hofmaier]

No it's a "clean" ubuntu image installed in Virtual Box with RVM and ruby installed following the RVM guide https://rvm.io/rvm/install

I did upgrade via RVM from ruby-2.1.5 [ x86_64 ] to   ruby-2.2.3 .

Can you help me reproduce this? What versions are you using of:

- rvm
- Ubuntu

I would like to be able to see this fail in the expected way, so that I can understand root causes.

[Lars Kanis]

Hi all,

I did a quick check with rake-compiler-dock (which coincidentally is based on Ubuntu-14.04). It has no libgmp-dev package installed and rvm install looks like this:

lars@d14816859b44:/home/lars/comcard/nokogiri$ rvm install 2.2.3
Searching for binary rubies, this might take some time.
Found remote file https://rubies.travis-ci.org/ubuntu/14.04/x86_64/ruby-2.2.3.tar.bz2

So the root cause is that rvm installes a binary ruby, which is linked to libgmp, but doesn't install the libgmp-dev package. Ruby runs fine this way, but extensions will not compile. So IMHO this is a rvm issue.

[Gerald Hofmaier]

I was using rvm 1.26.3 (latest) and Ubuntu 14.04.3 LTS.

Looks like Lars has got to the bottom of the issue. I will post a ticket with RVM if Lars has not already done so.

Many thanks,

Gerald

[Mike Dalessio]

Looks like Gerald opened an issue with RVM here:

    https://github.com/rvm/rvm/issues/3509

Thanks to everyone for helping diagnose this!
