Installing Capybara-webkit on Fedora

Question

So I'm on Fedora 17 trying to install Capybara Webkit. I followed the directions here and did a bundle install for another (near-identical) branch of this project, so I know it works.

When I try to bundle install, it has this error. Anyone have thoughts, or should I just log a bug with co?

Installing capybara-webkit (0.12.1) 
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

An error occurred while installing capybara-webkit (0.12.1), and Bundler cannot continue. Make sure that gem install capybara-webkit -v '0.12.1' succeeds before bundling.

Answer 1

version 0.12.1 is quite an outdated version of the gem - I had a lot of trouble getting a similar version installed for an older project I had.

I recommend upgrading to a newer version - the dependencies will be newer and the installation will be a lot less hassle.

capybara-webkit depends on a WebKit implementation from Qt, a cross-platform development toolkit. You'll need to download the Qt libraries to build and install the gem.
