MySQL Ruby Gem install issues

So I know that this question has been asked before, and I have looked through all of the previous answers and still can't find a solution. Hoping you all can help.

The setup: I am running Mac OS X 10.6 Server. I have used the built in MySQL install on web apps and it works great. Now I am trying to run a RoR app that requires MySQL.

So, whenever I enter

gem install mysql

it spits back the following error:

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

/Users/admin/.rvm/rubies/ruby-1.9.2-p180/bin/ruby extconf.rb --with-mysql-config=/var/mysql
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

Provided configuration options:
    --with-opt-dir
    --without-opt-dir
    --with-opt-include

    --with-opt-lib
    --without-opt-lib=${opt-di开发者_StackOverflow中文版r}/lib
    --with-make-prog
    --without-make-prog
    --srcdir=.
    --curdir
    --ruby=/Users/admin/.rvm/rubies/ruby-1.9.2-p180/bin/ruby
    --with-mysql-config
extconf.rb:35:in ``': Permission denied - /var/mysql --cflags (Errno::EACCES)
    from extconf.rb:35:in `<main>'


Gem files will remain installed in /Users/admin/.rvm/gems/ruby-1.9.2-p180@rails3/gems/mysql-2.8.1 for inspection.
Results logged to /Users/admin/.rvm/gems/ruby-1.9.2-p180@rails3/gems/mysql-    2.8.1/ext/mysql_api/gem_make.out

So, through my research, I tried to specifically state the location of the MySQL install.

gem install mysql -- --with-mysql-config=/var/mysql

Unfortunately, with the same results.

Any ideas of where to go from here?

Thanks!

Kevin

Kevin,

On Mac OSX Lion 10.7 this command helped me install the mysql2 gem:

sudo gem install mysql2 -- --with-mysql-lib=/usr/local/Cellar/mysql55/5.5.30/lib --with-mysql-include=/usr/local/Cellar/mysql55/5.5.30/include/

Before this I did install mysql55 via brew like described above.

Your milage may vary, but here's what seemed to work for us. First, ensure you have the right libraries on there first (from Apple):

http://www.opensource.apple.com/other/MySQL-53.binaries.tar.gz

Install those via:

sudo tar -xvf ~/Downloads/MySQL-53.binaries.tar -C /

Then, for our 10.6 Server, the location of mysql_config was different:

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

---

gem install mysql2 -- '--with-mysql-lib="c:\Program Files\MySQL\MySQL Server 5.5\lib" --with-mysql-include="c:\Program Files\MySQL\MySQL Server 5.5\include"'

Using the above worked with ruby Ruby 2.0 on Windows. I changed the library to just lib instead of lib\opt because lib\opt is not present in MySQL Server 5.5.

I picked the above command from a solution to this problem presented at: http://rorguide.blogspot.com/2011/03/installing-mysql2-gem-on-ruby-192-and.html

I had success with this sudo gem install mysql -v '2.8.1' -- --with-mysql-config=/usr/local/mysql/bin/mysql_config but specifying the mysql version that I need
