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

Windows is giving me problems all time. But this is all I have at Work. Thank You guys.
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
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

In your response to how to specify configuration options with gem and mysql2, it's something like this:
gem install mysql2 -- --with-mysql-dir=c:\mysql-connector-c-6.1.1-win32
See details here:
https://github.com/brianmario/mysql2
Can someone shed some light on this?
Sure - the problem is to do with Windows' compatibility with the MYSQL2 gem - by default, Windows does not come with the MYSQL header files which are required to allow the gem to connect with MYSQL
In order to install it, you need to install the MYSQL C-Connector package, and use it to give your gem the C++ header files it needs to run:
--
We've written a tutorial about this here
It's actually relatively simple to install the mysql2 gem if you do this :
Install / unzip the MYSQL C-Connector 32 bit package on your system
Install the gem, referencing the path without spaces
Copy libmysql.dll to your Ruby installation
The first step is download the latest version of mysql 32-bit c-connector. Unzip / install into a path without spaces - this is essential.
The second step is to use the following command to install the gem, referencing the c-connector files:
gem install mysql2 --platform=ruby -- ‘--with-mysql-dir=”C:\mysql-connector-path”’
Finally, you should copy the libmysql.dll file from the /bin folder of your C-Connector files to the /bin directory of Ruby
This should install the gem
i have the following error when i run this command, please help

I recall having a similar problem on my Lion OS. Try this out. I found it lying around in my ~/.bash_profile. Add to your ~/.bash_profile:
export DYLD_LIBRARY_PATH=/usr/local/mysql/lib:$DYLD_LIBRARY_PATH
or
export DYLD_LIBRARY_PATH=/usr/local/mysql/lib
Problem is quite simple, my OS is win 7 x64, I installed DevKit-tdm-32-4.5.2-20110712-1620-sfx.exe, it works well like this:
C:\DevKit>ruby dk.rb install

what should I do?
thanks a lot!
it can't find mysql. did you have installed mysql?
for windows x86:
gem install mysql2 --platform=ruby -- '--with-mysql-lib="c:\Program Files\MySQL\MySQL Server 5.5\lib" --with-mysql-include="c:\Program Files\MySQL\MySQL Server 5.5\include"'
to install specific version, like v 0.3.10
gem install mysql2 -v '0.3.10' --platform=ruby -- '--with-mysql-lib="c:\Program Files\MySQL\MySQL Server 5.5\lib" --with-mysql-include="c:\Program Files\MySQL\MySQL Server 5.5\include"'
for windows x64
gem install mysql2 --platform=ruby -- '--with-mysql-lib="C:\Program Files (x86)\MySQL\MySQL Workbench CE 5.2.35" --with-mysql-include="c:\Program Files\MySQL\MySQL Server 5.5\include"'
I'm trying to install the mysql2 gem on 10.6 server and I get an error message I haven't seen:

I've tried a couple things, specifying where the built-in MySQL is stored sudo gem install mysql2 -- --with-mysql-dir=/var/mysql and also replacing the built-in mysql with the pre-built 64-bit installer from mysql.com
Any ideas?
Figured it out:
sudo env ARCHFLAGS="-arch x86_64" gem install mysql2 -- --with-mysql-config=/usr/local/mysql/bin/mysql_config
I found out you have to have the package mysql-devel installed ... On Centos
do yum -y install mysql-devel and you're good to go.
I have the same problem on OSX 10.5 with RVM with the "system" Ruby interpreter. Using Ruby 1.8.7 through RVM fixed the situation.
