I've been looking at the source for plucker and have been attempting to compile it and assume I've not got my environment right. I'm running on a Windows 2000 machine and I assume that this is compiled using gcc. The makefile and viewer.rcp file both have an in extension, do they need to be ran through some other program? I'm guessing that in indicates some kind of scripting language I'm not familiar with. Would appreciate some help to figure out what I'm doing wrong. Thanks Richard
