mysql2 gem installation fails
Solution 1
I got this working:
wget http://cdn.mysql.com/Downloads/MySQL-5.5/MySQL-devel-5.5.27-1.el6.x86_64.rpm
rpm -Uvh MySQL-devel-5.5.27-1.el6.x86_64.rpm
gem install mysql
gem install mysql2
Solution 2
have you installed mysql ?
if not do so also you need to install the mysql dev files for native compilation of gem
sudo yum install mysql-devel
check this already explained Errors Installing mysql2 gem via the Bundler
Solution 3
if get the error like this
$ sudo yum install mysql-devel

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
try this
sudo yum --enablerepo=remi -y install mysql-devel

My stack is as follows:

Installed MySQL 5.5 (followed steps at http://www.if-not-true-then-false.com/2010/install-mysql-on-fedora-centos-red-hat-rhel/ because yum still has MySQL 5.1 and if I try to yum install any mysql related package, it will of course break as yum will expect 5.1)

When I try to install mysql2 gem, I get following error:

Mysql is running properly and I have already created db and tables in it and sql are running without any issue.
Is it possible to have mysql2 gem installed in my stack? If so then any idea what I am missing?
UPDATE : I tried
yum install mysql-develit throws error because I have mysql5.5 installed, using Remi repository. While Yum expects mySql 5.1 -

JVK over 11 yearsFinally I found how it can be fixed. I had installed mysql-devel version in Remi repo. yum --enablerepo=remi,remi-test install mysql-devel and then gem install mysql2 Boom.. done. Thanks @tadman for the hint.
