Bad do_mysql-0.2.2 Gem

If your getting this error whilst attempting to load up DataMapper in Merb (the rake dm:install:mysql portion, or just gem install do_mysql). Here’s how I fixed it…

Started merb_init.rb ...
Loading dependencies...
dyld: NSLinkModule() error
dyld: Library not loaded: /opt/local/lib/mysql5/mysql/libmysqlclient_r.15.dylib
  Referenced from: /usr/local/lib/ruby/gems/1.8/gems/do_mysql-0.2.2/lib/mysql_c.bundle
  Reason: image not found
Trace/BPT trap

Try this…

# sudo -s
# cd /usr/local/lib/ruby/gems/1.8/gems/do_mysql-0.2.2/ext
# make clean
# vim mysql_c.i
[change any bad paths to correct mysql locations in your OS]
# make all
# rm ../lib/mysql_c.bundle
# cp mysql_c.bundle ../lib

DataMapper with MySQL should now work in Merb! Happy hacking once more…

That didn't specifically work for me, but sent me on the right path. On OSX (10.5), it couldn't locate my copy of mysql_config in /usr/local. I ended up modifying the ext/extconf.rb file to point to a correct path for mysql_config by replacing line 15 with location = "path/mysql_config". After that, I just ran a rake install in the do_mysql directory and now it's golden.
