Brian,

Good catch. I already had the GeoIP C library installed. I’ve since updated the install instructions above to include that.

Thanks.
Aaron

Does GeoIPCity return any city information?

irb(main):008:0> g.look_up(‘99.136.101.165′)
=> {:country_name=>"United States", :latitude=>38.0, :longitude=>-97.0, :country_code=>"US", :country_code3=>"USA"}

Hi, I installed this plugin step by step, and when I run require ‘geoip_city’, I got following error msg:

LoadError: libGeoIP.so.1: cannot open shared object file: No such file or directory – /var/lib/gems/1.8/gems/geoip_city-0.1/./geoip_city.so

Can anyone help me with this? Thanks in advance!

Good find on the geoip_city gem aaron, it really is ridiculously faster (and getting a Hash back is a lot nicer also). From their README the default is to load the whole binary db into RAM, which will use at least 27MB of it (I haven’t tested how much it actually uses). But even passing the :filesystem parameter it seems a good 20x faster than the regular geoip gem.
