Can I build KWWidgets from Cygwin?
As of February 2006, we managed to build both VTK and KWWidgets under Cygwin. Sadly, they both would either behave in very unexpected ways or die horribly. We suspect issues with Cygwin’s Tcl/Tk libraries. No further support for Cygwin has been scheduled, but let us know if it is a concern. Note that you can use KWWidgets from a Cygwin shell without any problem though. KWWidgets even creates both a KWWidgetsSetupPaths.sh and KWWidgetsSetupPaths.csh script in your KWWidgets binary directory so that you can setup the proper runtime environment variables very easily.
