[Radiance-general] sudo recontrib

Thu Mar 17 14:02:20 PDT 2016

Hi Urtza,
I'm having trouble following what errors we're debugging. Are you okay not
using those materials, because with minimal effort you should be able to
fix it. If you look at the links Lars and I sent you can learn about
permissions and fix the padlock situation.
my comments are inline below.
Best,
Andy

Then I wonder why the files are found when you run with sudo but not found
without sudo. Or am I mis-understanding what is going on.

this doesn't help, you need to use the -l (lowercase L) option with ls, as
I orginally suggested, to report the file and directory permissions. And it
would help if you did it for every directory in the path. like this:

ls -l /usr/local/bin/radiance/bin
ls -l /usr/local/bin/radiance
ls -l /usr/local/bin/
ls -l /usr/local/bin/radiance/lib

The tutorial is outdated. dctiemstep no longer accepts the -n 8760 option.
This info is now contained in the matrix headers. run it again without -n.
