[Radiance-general] install Radiance on Mac

[Rob Guglielmetti]

Hi Marta,

Sorry this is all so confusing! Sounds like you grabbed the pre-built binaries from the NREL site. Let’s see if we can get you the rest of the way. 

1. Make sure you have the right installer. If you’re on MacOS, you want this one:

https://github.com/NREL/Radiance/releases/download/5.0/radiance-5.0.0-Darwin.dmg

2. Double-click the installer ("radiance-5.0.0-Darwin.dmg”), and then double-click the file inside ("radiance-5.0.0-Darwin.pkg”). Click “continue”, three times. Finally, click “install” to run the installer accepting the default location(s) for everything. 

You now have Radiance installed on your mac. What this really means is that you have a while bunch of files installed to the following locations:

/usr/local/radiance/bin (the Radiance executables — of which there are many, and ironically none of which are called “Radiance”)
/usr/local/radiance/lib (the Radiance “library folder” which contains loads of other important files used by Radiance)
/usr/local/radiance/man (the Radiance “man pages”, or manual pages — the main documentation to the Radiance programs

At this point, nothing actually works yet. =/  But, you’re close...

3. Next you need to add "/usr/local/radiance/bin” to your system path, and you need to create a new system variable called “RAYPATH” and set it to "/usr/local/radiance/lib”. You can/should also add "/usr/local/radiance/man” to your MANPATH system variable. You can see Andy McNeil demonstrate using “pico” to do this, starting at 7:38 in the video here:

https://www.youtube.com/watch?v=ptTmdKSfK68&feature=youtu.be&t=7m38s

NOTE: Be sure to use the paths I mention in this email and not the ones in Andy’s video.

After you do these three steps, you will have Radiance installed and functional. Then the fun really begins. =) Be sure to check out the tutorials here:

…and post any questions either here on this list, or over on Unmet Hours (https://unmethours.com/questions/). There are plenty of folks who are still here answering questions and offering advice, long after getting Ph.D.s. Matter of fact, some of us never even got Masters degrees. Still here. 

-Rob

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
