[Radiance-general] Persistent problems on dctimestep and Install

[Greg Ward]

Hi Germán,

You should never get a segmentation fault in Radiance, whatever you do.  At this point, we should take the discussion off-list to work out what is going wrong with your compile and/or operation on Ubuntu.  I will send another e-mail shortly.  Do not reply to this one.

We will post a summary of what we find to the list when the issue is resolved.  There may be some delays as I am presently on vacation.

Cheers,
-Greg

Long story short, the NREL precompiled Radiance for Windows returned only zeroes when dctimestep was called (Andy McNeil helped me to discard syntax errors ... THANKS FOR THAT); Ubuntu used to give me no answer, then it took turns between "reinhart.cal not found" and some other similar things, and now it keep throwing "segmentation fault" (my sky vector is not full of zeroes). I already tried reinstalling my Linux distribution, compiling the Head version (I think I did it ok), searching on the web, preinstalling x11 dev library, and installing Learnix... but "segmentation fault" keeps there, in the two PCs.

I am pretty stucked here. If there is any trick for installing RADIANCE or getting the permissions to avoid "segmentation fault", any advice would help a lot.
