Re: gEDA-user: gsch2pcb problems - I think!

People,

I just created a 4-slot symbol and associated 1153 pin footprint for a
Xilinx element that I need to route.  This morning I set out to test
these elements to see if they worked together OK.  Well -

I created a dummy schematic composed of the 4 slot elements, and
connected the power and ground connections to various net names.
Actually, that's not quite true, the GND connection is the GND symbol
from the library.

I then set up a project1 file to facilitate gsch2pcb and ran the
command 

    gsch2pcb project1

The screen showing how things ran is attached below.

I call your attention to the line FORMAT: error with call.

I opened the resulting files in PCB and everything looked OK until I
tried to locate the GND net.  It was simply missing.
Checking the netlist file, GND existed as a name, however there were no
entries for the net.

An attempt to autoroute the existing nets resulted in dropping me clear
out of the PCB program.

I did recently update to gEDA-20061214, but if my memory isn't failing
me, I've routed 3 small boards since then.

Any assistance would be appreciated.

ok, some background info.  gsch2pcb calls gnetlist 3 times.

once with -g PCB to get the netlist
once with -g gsch2pcb to get the footprints
once with -g pcbpins to get a pcb command file that updates the pin names in pcb. If this is left off, nothing bad happens

It is the -g PCB run that is failing since your netlist is corrupted.

That error looks like it came from the following line in gnet-PCB.scm:
(define (PCB:display-connections nets)
  (apply format #f "~:@{~A-~A ~}\n" nets))


so I think something in the guile world has overflowed. I can try to dig through it if I have a test case.
