Answer 1

for people who didn't use brew to install mysql and use mysql 5.6 and higher:

according to this answer

you need to edit mysql_config which was placed in my case here: /usr/local/mysql-5.6.12-osx10.7-x86_64/bin

and change cflags and cxxflags to:

cflags="-I$pkgincludedir  -Wall -Os -g -fno-strict-aliasing -DDBUG_OFF " #note: end space!
cxxflags="-I$pkgincludedir  -Wall -Os -g -fno-strict-aliasing -DDBUG_OFF " #note: end space!

after this manipulations

$ gem install mysql2 -v '0.3.13'

goes flawlessly

Answer 2

This method is for Rails 3.1.0 (and hopefully up) on 64 bit machine. I used on Ruby-1.9.2-p180.

This blog answered it: http://www.tatvartha.com/2010/10/installing-mysql-gem-with-bundler-on-snow-leopard/

Basically, the method above: $ sudo env ARCHFLAGS="-arch x86_64" gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config

may work, but without bundler.

To do it with bundler, first must run this on terminal:

bundle config build.mysql2 --with-mysql-config=/usr/local/mysql/bin/mysql_config

Note "mysql2" not "mysql" as shown in that blog.

That adds a config to ~/.bundle/config file

Then add this to ~/.bash_profile:

export ARCHFLAGS="-arch x86_64"

That is the same with telling bundler to run the command on top of this post.

Answer 3

For those on Fedora 21, and you already installed mysql-devel:

yum install redhat-rpm-config

solved the problem for me. see: redhat docs

Answer 4

Ok guys for me the solution was:

$ sudo brew install mysql

$ sudo env ARCHFLAGS="-arch i386" gem install mysql -- \
  --with-mysql-dir=/usr/local/mysql --with-mysql-lib=/usr/local/mysql/lib \
  --with-mysql-include=/usr/local/mysql/include

source: http://wonko.com/post/how-to-install-the-mysqlruby-gem-on-mac-os-x-leopard

OR :

$sudo env ARCHFLAGS="-arch x86_64" gem install mysql -- \
  --with-mysql-dir=/usr/local/mysql --with-mysql-lib=/usr/local/mysql/lib \
  --with-mysql-include=/usr/local/mysql/include

If your mysql version is 64Bits

After that i had a lot of problems because if i want to create the database:

$: bundle exec rake db:reset

i was receiving this error:

dyld: lazy symbol binding failed: Symbol not found: _mysql_init
  Referenced from: /Users/workdreamer/Sites/cavortify/implementation/cavortify/mysql/ruby/1.8/gems/mysql-2.8.1/lib/mysql_api.bundle

  Referenced from: /Users/workdreamer/Sites/cavortify/implementation/cavortify/mysql/ruby/1.8/gems/mysql-2.8.1/lib/mysql_api.bundle
  Expected in: flat namespace

The solution is: On your gemfile add: gem "ruby-mysql"

Ok, one day and a half to find the solution.

Have a nice day!

Answer 5

My problem was the result of first installing MySql via the downloadable binary. It was originally installed at version 5.5.28. I then attempted to install via homebrew. Brew installed version 5.6.x. HOWEVER in the process of installing via homebrew, the symlink for /usr/local/mysql was still pointed to 5.5.28.

Update your symlink to whichever version was installed via homebrew.

ex: /usr/local/mysql -> /usr/local/Cellar/mysql/5.6.13/

This could be just part of the solution.

Answer 6

For mariadb:

sudo apt-get install libmariadbclient18 libmariadbclient-dev

Then

gem install mysql2

could be successfully installed.
