Ok this is resolved, steps included below for Debian users who are having the same problem: The root of the problem when I went off the reservation and used a testing package for mySQL in my Sarge distro (needed 5.0.x instead of the Sarge 4.0.x). This caused the gem install mysql to error. When I upgraded, libmysqlclient12 remained. So I removed that: # apt-get remove libmysqlclient12 Also I removed all ancillary ruby packages since I did a manual compile/install. There were probably a few conflicts in the list of installed packages, so I decided to clean things up. # dpkg -l | grep ruby # apt-get remove libruby1.8 # apt-get remove libmysql-ruby1.8 # apt-get remove libmysql-ruby Next I made sure I had the correct libmysqlclient package: # apt-get install libmysqlclient15-dev --fix-missing Finally, I optimistically attempted to run the gem install: # gem install mysql And that finally ran without error. I then launched my app using mongrel, and the lost connection error was gone. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
