What I'm trying to do

I'm trying to install Nesta CMS but one of the runtimes dependencies fail to install : rdiscount.

Normal Output as root :

 % gem install rdiscount ~ linux-7o7a Building native extensions. This could take a while... ERROR: Error installing rdiscount: ERROR: Failed to build gem native extension. /usr/bin/ruby.ruby2.1 extconf.rb mkmf.rb can't find header files for ruby at /usr/lib64/ruby/include/ruby.h extconf failed, exit code 1 Gem files will remain installed in /usr/lib64/ruby/gems/2.1.0/gems/rdiscount-2.1.8 for inspection. Results logged to /usr/lib64/ruby/gems/2.1.0/extensions/x86_64-linux/2.1.0/rdiscount-2.1.8/gem_make.out

Debug output as root (quite long): debug link

I needed to install the ruby developper package ruby-devel :

% zypper install ruby-devel ~ linux-7o7a Loading repository data... Reading installed packages... Resolving package dependencies... The following 2 NEW packages are going to be installed: ruby-devel ruby2.1-devel 2 new packages to install. Overall download size: 3.1 MiB. Already cached: 0 B. After the operation, additional 20.1 MiB will be used. Continue?

After that, rdiscount installed well :

% gem install rdiscount ~ linux-7o7a Building native extensions. This could take a while... Successfully installed rdiscount-2.1.8 Parsing documentation for rdiscount-2.1.8 Installing ri documentation for rdiscount-2.1.8 Done installing documentation for rdiscount after 0 seconds 1 gem installed
