Loading netlists (was Re: gEDA-user: Land Grid Array packages)

[Tom Cook]

Thanks for the suggestions; I have figured out that making newlib footprints
is not nearly as scary as the M4 version.

But now when I try to load a netlist, pcb refuses saying, "Empty netlist
file!"  The netlist file I am trying to load contains the following:

unnamed_net8    U1-1 J1-8
unnamed_net7    U1-10 J1-7
unnamed_net6    U2-16 J1-6
unnamed_net5    U1-2 U2-3 J1-5
unnamed_net4    U2-1 U1-3 J1-4
unnamed_net3    U2-2 U1-12 J1-3
unnamed_net2    U1-11 U2-7 U2-14 J1-2
unnamed_net1    U2-10 U1-4 J1-1

As you can see, it is not a complex design, and the netlist file is not
empty.  Is this likely to be something I have messed up in my footprints?
Or is it something else?  (Note: both U1 and U2 use footprints that I have
developed myself).

Thanks for your help,
Tom
