I'm new to gaf/pcb. My first layout caused an infinite loop in gsch2pcb. This seems to be due to an infinite loop in the SIL m4 macro, which is due to two things:
1) The macro has what I'm guessing is cut'n'paste code left from DIL to draw dividers on the silkscreen "pins/2-1" times instead of "pins-1" times, which means any odd SIL is going to make a non-integer end, and 2) The forloop macro loops from start to exactly equal to end, so if the start is less than the end (eg SIL for 1 pin has no dividers) or the expression produces a fraction that can't match, the m4 will loop forever. The solution to (2) is more important because it probably affects many macros. My m4 skills are rusty, but I think this replacement (in common.m4) should work: define(`forloop', `pushdef(`$1', `$2')_forloop(`$1', `$2', `$3', `$4')popdef(`$1')') define(`_forloop', `$4`'ifelse(eval($1 < `$3'),1, `define(`$1', incr($1))_forloop(`$1', `$2', `$3', `$4')')') The change to PKG_SIL in misc.inc is trivial, change the end of the loop to $4-1 instead of $4/2-1. -- Ben Jackson AD7GD <[EMAIL PROTECTED]> http://www.ben.com/ _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
