FAQ - Known problems

First off: Hello! I am the new guy. My name is Aksel and i am from Berlin, Germany. Thank you all ver much for the rich resources which can be found around here. I have been working with Radiance from time to time during the course of the last 10 years, but unfortunately not further but keeping up to date with principles.

Now i am digging again, and i seem having problems with the installation on Mac/Mountain Lion. Everything works well at first, i can i.e. compile .octs and render them without problems, which gives me the feeling i didn't mess up the install and paths in general.

But there are some spots which seem to be broken for me, for instance falsecolor aborts telling me helvet.fnt is missing, yet it's there. Or i cannot start off x11meta as in objline foo.rad | x11meta, gives me an error too. In order to find out which parts have been messed up by me, and which parts are known problems, is there any FAQ with pitfalls for cases like these? I couldn't find one, please excuse me if i missed it.

Thanks a lot,
Aksel

Hi Aksel!

The most important is to check that RAYPATH includes all needed directories. And that these actually contain the libraries you'd expect there. Type

echo "$RAYPATH"

and then find whether at least rayinit.cal is in one of the returned directories.

About x11meta, I am not sure how well it works in general. There seam to be several pitfalls with the meta-utilities.

Hm, and thanks for reminding me that I started setting up a FAQ-system and somehow did not really complete the job so far :wink:

Cheers, Lars.

Hi Lars,

Cheers, thanks for the quick answer!

The folder which the echo hands back is existing, and filled with stuff, amongst the rayinit.cal.

Ah, i see. If there are known pitfalls i give the metautilites a break for now.

I would love to use falsecolor with the helvet.fnt though, any idea on that one?

Thanks a lot,
Aksel

Hi Aksel, nice to see you on this list! How did you acquire the Radiance
source code? Did you just grab the HEAD? If so, you need to grab the
"auxiliary files" archive from the same place you got the HEAD:

http://www.radiance-online.org/download-install/download-radiance/un-offici
al-head-version/index.html

I'm pretty sure that's where helvet.fnt lives. You can also use the CMake
build system. There was a thread on the dev list recently:

Hi Rob,

Nice to see you too!

I got the precompiled binaries, worked fine. The thing is, i see the 'helmet.fnt' sitting right here in the lib-folder RAYPATH points to- it's just that falsecolor does not see it the way i do :slight_smile:

Aksel

Hmmm. Which binaries did you install from?

These:
  • rad4R1_macosx_bin.tar.gz
  • rad4R1all.tar.gz

'helmet.fnt'

Should have been helvet.fnt, that was spelling correction.

I am not here to report a bug or something, i still think the mistake is on my side. I just cannot find out what it is as virtually everything else is working nicely from the first install on.

I am running a Apple MacBook Pro 64 with Mountain Lion on it. Just curious if nobody ever had any issues with the font falsecolor needs?

If you search in the archives a bit you should find the same problem
mentioned before. I remember I had to deal with this issues before. From
memory it was either that the file was not included in the distribution
files or it was not copied in the right location by the build script. Can
you tell us where the file is on your system and where your $RAYPATH
variable points to.

Regards,
Thomas

Hi Thomas,

I found the problem with my paths. It was my error, i reentered all paths as stated on the site. Works now like a charm!

The problem though came because i first installed the version from NREL http://openstudio.nrel.gov/getting-started-developer/getting-started-radiance

There it says:
"On MacOS or Linux, add these lines to your .profile or .bashrc —assuming you are using the bash shell (this is most commonly the default)— files, respectively:

PATH=.:/usr/local/radiance/bin:$PATH
RAYPATH=.:/usr/local/radiance/lib:$RAYPATH
Export PATH RAYPATH"

Those where the paths i entered before, and those didn't do it. Most likely because appending to a non-existing RAYPATH won't do a thing?

Aksel

Good call, Aksel. I never thought the order mattered, but maybe it does.
At any rate, Andy's instructions are far more detailed than mine on the
OpenStudio site; I'll have to do something about that!

Glad you're up and running, in any case.

Appending the $RAYPATH to the end should not break anything. If it is
not set, nothing will be appended, that it is.

If you really typed Export as above, with capital E, that may be the
problem.

I am not sure about the syntax. On bash I would not first define the
variables and than export them to the environment, but directly set the
environment variables as

export PATH=.:/usr/local/radiance/bin:$PATH
export RAYPATH=.:/usr/local/radiance/lib:$RAYPATH

But both may be valid.

Cheers, Lars.

Thanks Lars, and NO THANKS to Microsoft for their idiotic autocorrect crap!

I'll fix that.
