Question

I've been searching for this error, reinstaled everything, and tried everthing. All I found here are old posts, and old versions. Yes, I've downloaded MySQL C Connector and move the lib to that ruby dir. Still nothing.

Im running a PC WINx64 Ruby version 2.0.0-p195 Lastest Version of DevKit

**gem install mysql2**
**Temporarily enhancing PATH to include DevKit...

Could not create Makefile due to some reason, probably lack of necessary

Solution

I've downloaded the connector from http://dev.mysql.com/downloads/mirror.php?id=412857

and typed in the command prompt

gem install mysql --platform=ruby -- --with-mysql-include=C:\mysql-connector-c-6.1.0-winx64\include --with-mysql-lib=C:\mysql-connector-c-6.1.0-winx64\lib

OTHER TIPS

Try to install the mysql gem using following command

gem install mysql2 -- '--with-mysql-lib="c:\Program Files\MySQL\MySQL Server 5.0\lib\opt" --with-mysql-include="c:\Program Files\MySQL\MySQL Server 5.0\include"'

note: Change the mysql installation directory as per your installation
