Re: gEDA-user: gnetlist in a Makefile

[Richard Prescott <richard@xxxxxxxxx>]

Ok, there is missing semi-columns in your statement, "make" will put all
lines ended with "\" together in a single line

if cmd1; then cmd2; else cmd3; fi


Although, personally,  I prefer to not use bash to do ifs in Makefiles.
so:

$(objects).drc : $(objects).sch
	gnetlist -g drc2 $(objects).sch -o $(objects).drc

$(objects).cir : $(objects).sch $(objects).drc
	grep -qv ERROR $(objects).drc
	gnetlist -g spice-sdb $(objects).sch  -o $(objects).cir
