Hi Rick,
I actually asked the same question a while ago Rails + Firebird 2.1.x - Rails - Ruby-Forum. And as you can see there was no answers for that. But, after some trial and error I managed to get it to work.
Before I posted the thread asking for help, I went through the following tutorial Mariuz's Blog: Installing Firebird Active Record driver for Ruby, but I did not get it to work, and that is when I got that error message. But, I found out what was missing.
I installed it under Ubuntu Linux, and first I made sure that libfbclient.so was in /usr/lib. In other words, if you installed from the repository, then make sure that you install firebird-dev. I always install from the archives.
Next, you do the following:
1) install fb-0.5.9 2) install fb_adapter 3) go to the folder where fb-0.5.9 is (in my case it is under /usr/lib/ruby/gems/1.8/gems/fb-0.5.9), and do a sudo make install. That should install fb-0.5.9.
That's it, you can now follow the rest of the tutorial from
Migrations aren't yet working.
Good luck!
Fidel.
