Rails 2.2 is already out, and this release should be an exciting leap torwards multithreading, i18n etc. I definitely will give it a try. Today I’m using 2.1.2, and each time I run ‘rake test:units’ I get distracted a bit by a message that tells me that internal Rails’ MySQL adapter already deprecated. So I decided to get rid of it.
>sudo aptitude install mysql
Doesn’t work! It says some libraries are missing. And since build-essential I’ve already installed
>sudo aptitude install build-essential
I jumped into Google. I’ve found that some development version of libmysqlclient library is the cure. Both
>sudo aptitude install libmysqlclient5-dev
and
>sudo aptitude install libmysqlclient12-dev
are failed. So, how to find out the actual version number?
> sudo aptitude search mysqlclient | grep dev
It would print out something like this:
v libmysqlclient-dev -
i libmysqlclient15-dev – MySQL database development files
So it turns out that there is a meta-package(libmysqlclient-dev), and performing following command
>sudo aptitude install libmysqldev
would care about right version automatically. Now the time to install mysql gem has came:
>sudo gem install mysql
And finally, if you brave enough, do the last move:
>sudo gem update rails
