(running OS X 10.5.5, MySQL 5, Rails 2.1, Ruby 1.8.7)
I do not understand why after running :
sudo gem update --system
Updating RubyGems
Nothing to update
sudo gem install rubygems-update
Successfully installed rubygems-update-1.3.1
1 gem installed
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
and restarted my rails app, I still have this warning…
DEPRECATION WARNING: You’re using the Ruby-based MySQL library that
ships with Rails. This library will be REMOVED FROM RAILS 2.2. Please
switch to the offical mysql gem: gem install mysql See

what’s missing ?
everything seems to be into : /usr/local/lib/ruby

Has it done something like compile it for the wrong architecture ?
(what does lipo -detailed_info say for mysql.bundle ?)
Fred
I also run :
MacErwin:mysql-2.7 yves$ lipo -detailed_info /usr/local/mysql/lib/
libmysqlclient.dylib
input file /usr/local/mysql/lib/libmysqlclient.dylib is not a fat file
Non-fat file: /usr/local/mysql/lib/libmysqlclient.dylib is

seems wrong ???
cd /usr/local/lib/ruby/gems/1.8/gems/mysql-2.7

That is wrong. Looks like you downloaded the x86_64 version of mysql
(which is fine - there’s no issue with your server being that), but
that currently means you only have the x86-64 libs. you then end up
with a gem that can only run against those libraries. Your ruby
executable is probably an i386 executable, so it can’t load the gem
compiled for x86-64
Fred
Thanks… so what should I do now … ?
Easiest thing is probably to just reinstall the x86 version of mysql.
You may need to recompile the gem after that.
