[Radiance-general] install Radiance on Mac

Sun Sep 27 17:12:56 PDT 2015

Hi Chris,

I had replied to one of those emails from afternoon.  I think the Penn State
webmail server isn't smart enough to figure out the difference between
personal emails and mailing lists.Anyway, my reply is below..

Actually, if you got as far as "Where do you want the library files.", you
can just follow along with Andy's video from around the 4:59 mark..

Instead of typing any  directory or path names you can just keep pressing
enter( or return) to select the default options.

Marta,

Not too many years ago, I was in the same place as you, and I fortunately
had help from Rob Shakespeare (one of the authors of the book "Rendering
with Radiance"). So, the least I can do is pass on the knowledge to the next
generation of users. If you are still stuck after some trial and error, I
would be happy to help out via personal communication.

If one looks back on the archives of this list, there is a constant exodus
of young users who disappear after they get their masters/PhD's, so I am
playing my part to take some of the burden off the senior developers by
offering a little help here and there to the new users...

PS. for those who have read this far: How is the new knowledge base platform
working? I was happy to hear there were some recent efforts, but I haven't
seen or heard about it for a few weeks.

Best,
Chris

Bello greg,

That's what I did, I downloaded the pre-compiled binary for Mac OSX. So what
should I do next?

I can't create libraries and so on because I have absolutely no idea how to
do... I want to cry!

Sorry but I feel completely ignorant in this subject.

Hi Marta,

You should just download and use the package installer from NREL:

            https://github.com/NREL/Radiance/releases/tag/5.0

It's much easier than compiling from source for those not used to such
things.  Since you're on a standard OS X distribution, you should have no
problem.  The recommendations for installing X11 and the developer tools
still apply, however.

Cheers,

-Greg

Where do you want the library files [/usr/local/lib/ray]?

What should I type?

I am still stuck on the first steps. as I type the command  

tar -zxf rad5R0all.tar.gz

I get the message:

tar: Error opening archive: Failed to open 'rad5R0all.tar.gz'

What does it mean?

If you are trying to unzip the latest release, the command is most likely:

tar -zxf rad5R0all.tar.gz

-zxf is options for the tar command, and the file name being unzipped is at
the end.

Here are my personal notes for installing on Mac and Linux (arrow > means
command line, double quotes means replace with appropriate file name,
brackets are notes):

1) install XCode from App Store
2) install X11

3) compile, by running these commands
> tar -xzf "radiance_release"
> tar -xzf "HEAD"
> cd ray/
> sudo ./makeall install
(use default, or direct to newly made 'bin' folder)
(use default, or direct to 'lib' folder)
> ./makeall library
(direct to 'lib' folder)

4) update your paths
> nano ~/.profile

Put these three lines in the .profile text file, replacing the appropriate
paths. Your paths will look different, but they are the paths to the 'bin'
'lib' and 'doc' folders created during the installation. If you're on a Mac,
the file will most likely be empty. If it's not empty, you can add these
three lines anywhere in the file.

export PATH=/Users/chris/Applications/rad50/ray/bin:$PATH
export RAYPATH=.:/Users/chris/Applications/rad50/ray/lib
export MANPATH=/Users/chris/Applications/rad50/ray/doc/man

5) close and reopen terminal, and test installation

> which mkpmap
> man mkpmap

Download mark stock's benchmark, open a terminal, change to the appropriate
directory, and type:
>tar -xf bench4.zip
> cd bench4
(for single core, type:)
>make
(for multi core, type:)
>NCPU=2; make smp

It will take a bit of practice and patience to get familiar with the Unix
command line, so give it time and take plenty of breaks (I recommend going
to the gym).

Hope this helps,
Chris

Hello,

I am completely new to Radiance and I am trying to install it on my Mac. I
have Yosemite 10.10.5. I have to use Radiance for my Master thesis.
I am already having a hard time in the installation. I am trying to follow
the video tutorial on the official website but it refers to an old version
(of both website and Mac software): everything is a little bit different and
I am doing something wrong. I can't even start: as I type the command -xzf
in order to extract the files, the terminal says: "command not found".
Does anyone know what I am doing wrong? Is there an updated tutorial where I
can see what I have to do step by step?
Thank you!

Marta
