Dear list, Quite some time since I wrote. I hope you are all keeping well. :) A strange thing I ran across this evening. I was not allowed to do: const double lunarSynodicMonth = 29.53059 ; const double daysLunarPhaseAngleTakesPerDegree = lunarSynodicMonth / 360.0 ; I got the following error: wdf-karanas.c:17: error: initializer element is not constant make: *** [wdf-karanas.o] Error 1 I would be grateful if anyone could shed some light. TIA.
