Regarding Radiance Installation, Qt-based rvu, and Objline issues

Hello everyone, Hello Rob,

I just uninstalled the standard Radiance package I had on my Linux (Debian
Wheezy) machine. This packaged was installed by the standard Add/Remove
Software utility in Debian. Then I downloaded
"radiance-4.2.a-Linux.tar32.gz" from the NREL's website and copied it's
"radiance" folder at /usr/local/. Then I added the RAYPATH in the .bashrc
file as per the instructions given on the website. I tried to check the
installation by running gensky command, and it works fine. But I have
observed some issues with "rvu -o qt" and "objline" :

1. "$ rvu -o qt myScene.oct" gives me this error: rvu:
/lib/i386-linux-gnu/i686/cmov/libc.so.6: version `GLIBC_2.15' not found
(required by rvu)

AND

2. "$ objline myScene.rad | x11meta" gives me this error: fatal - cannot
open file "/usr/local/lib/meta/vchars.mta", mode "r"

In the previous standard installation of Radiance, "$ objline myScene.rad |
x11meta" use to work fine. Do you know what has happened now? and, have I
re-installed radiance properly? Thank you!

Regards,
Vaib

Sorry, the second error is not from objline, I meant x11meta there.
Correction.

The version of glibc NREL's release was built against is newer than the one which comes with Debian Wheezy. A procedure for installing a newer glibc is given here:
  http://unix.stackexchange.com/questions/85505/need-to-install-glibc-2-14-on-wheezy

2. "$ objline myScene.rad | x11meta" gives me this error: fatal - cannot open file "/usr/local/lib/meta/vchars.mta", mode "r"

It looks to me like x11meta expects files at /usr/local/lib which haven't been copied there. Check and see if that's the case.

Thanks Randolph. Can you tell me if that glibc version is unduly recent? Meanwhile I can double check that the x11meta stuff is not my fault either.

Debian Wheezy is the current "stable" release. It was released just last December and contains glibc 2.13. So, off the top of my head--and Bernd might have a different opinion--I would say that if possible it would probably be best to make the binaries work with the stable version of Debian.

Thanks�Randolph.

You're welcome.

�Is there any documentation to properly install Radiance (latest one from NREL) ? Or if you can give some hint, because I couldn't find any such discussion on the web. Or my installation process mentioned in the trailing is good enough. Thanks!

I think once you patch up your install, that will work.

There really isn't much current documentation. Me, I'd be inclined to get the current cvs version from radiance-online.org and follow the instructions in the README, but that's a bit much if you aren't a software dinosaur like me. I think one could probably create a Debian source package without too much trouble, since most of that work is already done, but I'm not sure of the procedures.

Rob?
