Re: gEDA-user: Netlist error

[Robert Fitzsimons <robfitz@xxxxxxxx>]

I think I also got caught by this problem.  Attached is a schematic
which shows the problem and a patch which seems to fix the problem
(though I've not extensively tested it).  It seems to be related to the
recent new attrib API changes by Peter.

Relevant output from 'gnetlist -v power.sch' without patch:

.....
component CONNPWR
        pin 2 (2) Vcc
                CONNPWR 2 [1423]
        pin 1 (1) Vcc
                CONNPWR 1 [1458]
        pin 3 (3) GND
                CONNPWR 3 [1469]
.....

with patch:

.....
component CONNPWR
        pin 2 (2) VLED
                CONNPWR 2 [1423]
        pin 1 (1) VCC
                CONNPWR 1 [1458]
        pin 3 (3) GND
                CONNPWR 3 [1469]
.....

Subject: [PATCH] gnetlist: Fix problem with attached net attribute not being honored.

Seems to be an artifact introduced by the change to use the new
attrib API (b4996e267b5d9696f7e8122c40b31482ef852904).
