MySQL Install: ERROR: Failed to build gem native extension

I'm trying to get MySQL installed to the latest version due to some installation going wrong somewhere along the line. I run the command gem install mysql and I receive the following:

Building native extensions. This could take a while... ERROR: Error installing mysql: ERROR: Failed to build gem native extension.

I've searched, and tried a whole host of things, from installing specific versions to trying to reinstall ruby without any luck.

Any ideas where I may be going wrong?

EDIT: I installed XCode off my Snow Leopard DVD and the error just changed slightly to the following:

doing "which mysql" on the command line returns nothing, which means it's not recognizing it. I also installed the MySQL system preferences option, and I can't stop MySQL from running. Now I'm completely stuck as what to do!

EDIT EDIT

I've just completely reinstalled MySQL using this guide http://hivelogic.com/articles/installing-mysql-on-mac-os-x

Unfortunately this didn't work either, I still receive the same errors. I can't even do mysql -uroot at the command line, I get the error of:

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

So I think I've tried everything.

**SOLVED*

Sorry guys, the reason for this not working was because of the MySQL paths. I've blogged on it here: http://www.kieransenior.co.uk/2010/02/mysql-cant-connect-using-ruby-on-rails-mac-os-x-snow-leopard/

While these answers pointed me in the right direction, on Alpine linux the package I needed was mariadb-dev, eg. run apk add mariadb-dev before the gem install mysql command.

I had a similar experience, so here are the things that I tried

Firstly, I tried to install mysql's required packages by running the command below in my terminal

sudo apt-get install build-essential libmysqlclient-dev

Secondly, I tried updating rubygems on my system by running the command below in my terminal

sudo gem update --system

But I was still experiencing the same issue.

Here’s what worked for me

After much research I realized that I was using an almost out-of-date version of the mysql gem. I simply needed to use the mysql2 gem (mysql2 gem)and not the mysql gem, so I fixed it by running the command below in my terminal

gem install mysql2

This worked fine for me. Before running the last command, ensure that you've ran the first and second commands to be sure that everything is fine on your system.

That's all.

I hope this helps

Your Ubuntu OS need to install library for mysql client sudo apt-get install libmysqlclient-dev

After That just install bundle or bundle install

In order to resolve

Gem::Ext::BuildError: ERROR: Failed to build gem native extension error for mysql2,

I think libmysql-ruby got changed with ruby-mysql

Simply try with following commands,

sudo apt-get install ruby-mysql

& then

sudo apt-get install libmysqlclient-dev

on OSX mountain Lion: If you have brew installed, then brew install mysql and follow the instructions on creating a test database with mysql on your machine. You don't have to go all the way through, I didn't need to After I did that I was able to bundle install and rake.

Installing the mysql gem on OSX

in a terminal.. First do a ‘locate mysql_config’ and then replace the path in the following command with where that file is.

$ sudo gem install mysql -- —–with-mysql-config=/usr/local/mysql/bin/mysql_config

I had also forgotten to actually install MySQL in the first place. Following this guide helped a lot.

http://www.djangoapp.com/blog/2011/07/24/installation-of-mysql-server-on-mac-os-x-lion/

As well as adding these lines to my .profile:

export PATH="/usr/local/mysql/bin:$PATH"
alias mysql=/usr/local/mysql/bin/mysql
alias mysqladmin=/usr/local/mysql/bin/mysqladmin

A number of people found this post helpful.

Also, I needed to do first type this:

yum install mysql-devel

and then:

gem install mysql

For some people you may need to type:

gem install mysql -- --with-mysql-config=/usr/local/mysql/mysql_config

First of all you need to differentiate between the MySQL as Server, MySQL as Client and the Ruby bindings to MySQL.

I'm not familiar with Mac, but for *nix OS you need to install MySQL through your package manager. To get the Ruby bindings installed with

gem install mysql

you need the development headers of ruby (in Ubuntu it is the package ruby-dev) and the development headers of the MySQL-Client (currently libmysqlclient16-dev in Ubuntu). I don't know if they are named different on Mac, but after you got those installed the Ruby bindings should install without any error.
