[Radiance-general] sudo recontrib

[Lars O. Grobe]

Dear Urtza,

two comments on your installation - this should be solved before you 
even start using a complicated combination of commands such as the 
three-phase method.

First, with a correct configuration of your system you will not need to 
run rcontrib as super-user (sudo). Your regular user account just needs 
read-access to the .dat and .cal files in this case, so why would you 
not grant the proper permissions?

Second, as rcontrib is not found, what makes you think it is installed? 
Did you install Radiance from sources, did the build complete without 
errors, and did you include the directory containing the binaries in 
your PATH environment variable? Does any other Radiance command work for 
you?

I would recommend having a look at Axel Jacob's set of tutorials first, 
including the unix-introduction. Otherwise you risk messing up a lot of 
your models with work-arounds, and even risk the integrity of your 
system by using sudo where it should definitively not be applied.

Cheers, Lars.
