Re: gEDA-user: DRC2 Problem (gEDA-2005080313)

[Carlos Nieves Ónega <cnieves@xxxxxxxxxx>]

Hi Neal,
the call to scm_sort_list_x "only" sorts the list returned by the
function g_get_slots, which is used by the backends to get the slots
used in a package. For example: if you use slots 1 and 3 of U1 in your
schematic, g_get_slots will always return a list (1, 3) after calling
scm_sort_list_x. Commenting out that call, g_get_slots may return (3,
1), so it will only affect to the backends relying on a sorted list.
IIRC, it shouldn't affect any report made by the drc2 backend. I think
others backends are not affected, but I can't tell it for sure. Just try
it.

Regards,

Carlos
