Question

MySQL Install: ERROR: Failed to build gem native extension.

Answer 1

A:

you can try to reinstall the latest version of xcode / dev. tools for snow leopard - this should fix your errors

This was one of the first things I did. Snow Leopard's version of XCode is installed on my machine.

Answer 3

A:

Attention: You need to specify -- key, and than --with-mysql-config=/usr/local/mysql/bin/mysql_config

Again, this answer is floating in many-a-place. In my instance, it doesn't work. Plus, mysql didn't exist for me in /usr/local/ I believe.

Answer 4

+3 A:

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.

Indubitably, there is a multi-packaged version which does both. I've gone through this process as well. I think you're right, I do need to differentiate between the two as this has been mainly my problem. Another option, perhaps, is to install MAMP and use that? What would I need then?

Kezzer 2010-02-03 13:00:08

MAMP stands for Mac, Apache, MySQL, Php.So you would still need a MySQL-Server and in addition Apache 2, and the php libraries for apache. I'm not sure if you can just select MAMP in your package manager and it will install all required files. Maybe a Mac user could help you out there.

Aurril 2010-02-03 13:45:44

Indeed it would fall short of the need for MAMP, but it was just an easy way to serve up a MySQL instance.

Kezzer 2010-02-03 14:17:52

This was exactly what I needed on Ubuntu: `sudo apt-get install ruby-dev` and `sudo gem install mysql`. Thanks!

Dan Breslau 2010-02-26 21:37:09

yep, this worked: 'sudo apt-get install ruby-dev libmysqlclient16-dev' then 'sudo gem install mysql'

Travis R 2010-09-07 23:47:01

Thanks Aurril - ruby-dev is what was missing in my case!

Answer 5

+3 A:

http://trevoke.net/blog/2009/04/17/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
Building native extensions. This could take a while…
Successfully installed mysql-2.7
1 gem installed

Trevoke 2010-02-03 16:36:36

This looks good, I'll have to try it when I'm back at home perhaps. Cheers.
