Re: gEDA-user: cant connect model to transistor.

[Anthony Shanks <yamazakir2@xxxxxxxxx>]

Change the value attribute to 2n2222 and read up on spice syntax. Your
model file (the model of the 2n2222) needs to be included in the
netlist which in your case it isn't.

Also consider using my netlister at http://spnet.code-fusion.net/
(shameless plug) it warns about things like this and the documentation
helps your avoid things like this. In summary every component needs a
value attribute and models need to be included in your netlist.
