[Radiance-general] error message "file coeff_perez.dat cannot be opened"

[Sotiris Papantoniou]

Hi Thomas,

 

I am running Ubuntu 11.04 and I installed Radiance through Synaptic package
manager

 

I copied the "coeff_perez.dat" file but gendaylit again did not work because
it could not access "defangle.dat"

 

I have now download the source code from the site but when I copy the file
to /usr/share/radiance the file has an "X" on the top  right of its image.

 

Any new suggestions?

 

Sotiris

Hi Sotiris.

 

How did you install Radiance/gendaylit?

 

If you are on Linux and used a recent Debian package then see here:

The package maintainer forgot to include the file in the package. You can
try to install an older package or use the source from the official website
(see below).

 

If you use another system (OS X or Windows) you should check that your
RAYPATH environment variable is set. Then check that the file is not in the
folders listed in RAYPATH.

 

If you are sure that you don't have the file grab the Radiance source code
from here:

 

http://www.radiance-online.org/software/rad4R0all.tar.gz

 

Extract the archive, search for the file and place it in one of the folders
listed in your RAYPATH. That should do it.

 

Regards,

Thomas
