[Radiance-general] Radiance on Cygwin: Starting problems

[Ramana Koti]

Hey,

Thanks Kirk, I had made the "void bright light" mistake which I corrected to
successfully create the octree file.

Coming to the second error:

$rview -vp 2.25 .375 1 -vd -.25 .125 -.125 -av .5 .5 .5 test.oct
I get a windows pop up error message saying rvu.exe - Unable to locate
component, This application has failed to start because cybX11-6.dll was not
found. Re-installing the application may fix this problem.

My installation folder "C:\radiance_stuff\cygwin\usr\X11R6\bin" contains
only a run.exe file and nothing else. I rerun the setup with X11R6 selected
and the message at the end says "nothing needed to be installed". Does that
mean the file is missing from the installation itself? What can I do to
correct the situation?

Ramana.
