I get this error

Gem files will remain installed in
/home/mark/.bundler/tmp/28288/gems/mysql2-0.2.17 for inspection.
Results logged to
/home/mark/.bundler/tmp/28288/gems/mysql2-0.2.17/ext/mysql2/gem_make.out
An error occured while installing mysql2 (0.2.17), and Bundler cannot
continue. Make sure that gem install mysql2 -v '0.2.17' succeeds
before bundling.

With a Ruby on Rails application and I can not solve it.

The cause of your problem is most probably in /home/mark/.bundler/tmp/28288/gems/mysql2-0.2.17/ext/mysql2/gem_make.out. And we can't help you wiothout knowing the contents of that file. – Holger Just

It sounds like you haven't got MySQL installed on your machine. – user358380

Most folks find this works:

sudo apt-get install libmysql-ruby libmysqlclient-dev

It's probably a compilation error. Maybe you don't have mysql development libs installed in your system.

I need to see the logs to make sure. Try it and paste the output here:

cat /home/mark/.bundler/tmp/28288/gems/mysql2-0.2.17/ext/mysql2/gem_make.out

Btw: wich operation system are you using?
