An error occurred while installing mysql2 (0.3.15), and Bundler cannot continue.
Make sure that gem install mysql2 -v '0.3.15' succeeds before bundling.

solution on other linux is

sudo apt-get install mysql-client libmysqlclient-dev

but don’t know how to install these packages on opensuse 13.1

I have no real knowledge about the particular action you are trying to do, but I understand that you do not even know how to manage software on openSUSE.

You use either the GUI: YaST > Software > Software Management, or the CLI with zypper

man zypper

BTW, next time you try to post computer text, please copy/paste it from the terminal in between CODE tags in the post. You get the CODE tags by clicking on the # button in the tool bar ofthe post editor.

#3 
sudo zypper in libmysqlclient-devel

Or use YaST->Software Management.

still getting error !

You haven’t explained exactly what it is that you are trying to achieve.
If you copied the commands you used into the CODE block, instead of just some output, we could see what you were doing.
You should not expect others to be able to access random file-sharing sites. This forum has its own http://paste.opensuse.org/.

I am guessing that you want to use Ruby Gems, and for some reason you are trying to compile a package designed for another distribution. OpenSUSE/SUSE has an excellent package manager, and a very large software library/repositories. That has always been on of its main “selling points”.

Ruby mysql2 is different from MariaDB/MySQL.

Open YaST > Software Management (either from the GUI or in a terminal). Search for “rubygem”. You will discover a selection of “gems”, incuding “rubygem-mysql2”, together with documentation, and a test suite. Select the packages you want, and “Accept”.
