gr crashes on executing the example about gr

[jheinen]

It seems that the GR framework has to be build for an older deployment target.
I will test this and probably correct the build settings in the next version (0.8), which is planned for next week. Is this OK for you?

Next week is perfectly fine for me, thanks!

BTW, Does that mean that it would run under OS X 10.10 (Yosemite), for
example?
That's the only upgrade I might consider, thus skipping 10.9.

Regards,

Hermen

I have to admin that I built the latest Conda package for GR on a Yosemite system. I probably should follow other developers' advice and build future packages on an older OS X host, e.g. 10.8 or even 10.6 (as I did before) due to some problems with Xcode 6. I will check this on my office desktop which I normally use to test GR packages with different OS X virtual machines.

If you plan to upgrade to Yosemite, don;t forget to re-install Xquartz.

Well, it ìs advanced stuff after all, this GR:-) Thanks for the advice, and I'll keep an eye for the next upgrade.

Hello again,
Today I finally got to installing gr again, but this time another issue arose. After trying the example in the "Getting started" section, I got the following error message:

from gr import pygr
pygr.plot([0,1,4],[3,2,5])
2015-09-02 13:25:38.461 python[1117:707] Could not locate GKSTerm.app.
2015-09-02 13:25:38.462 python[1117:707] Launching GKSTerm failed.

I figured it has something to do with XQuartz, and reinstalled that, but still no avail. Do you heve any further suggestions? I'm still on OSX 10.8.5, I should add…

Kind regards,

Hermen

PS: I continued on this thread because I couldn't find the option to create a new one...

[jheinen]

I'm sorry that there are (again) problems with the installation. I'll check this tomorrow on my office desktop. The next GR release will be self-contained and built without XQuartz, although this is not related to the current issue.

[jheinen]

As a temporary solution, please download the missing GKSTerm.app and unpack or move it to your Anaconda bin directory, e.g, if you installed Anaconda in your home directory:

cd $HOME/anaconda/bin
curl -O http://gr-framework.org/downloads/GKSTerm.zip
open GKSTerm.zip
rm GKSTerm.zip

Sorry for the inconvenience ...

[HermenB]

Thank you for this solution, I'll try it today. Just for my knowledge, what is GKSTerm.app exactly? When I googled it, I only found references to the gr-website. Is it an in-house developed product?
And to verify, as far as I know the only requirement for gr is pyopengl, is that correct? Or do I need other programs / packages, too? Specifically, in the gr code I found references to .xcodeproj, do I need Xcode to be installed?

[jheinen]

GKSTerm.app is part of the GR framework - it is the GR's native graphics driver for OS X. The requirements for GR are shown in the installation section of the website.

With the next release, the optional packages can automatically be downloaded and built with a shell script (3rdparty/makeself.sh). The result is a self-contained GR distribution, thus minimizing dependencies and improving portability.

For the Python part, numpy is the only requirement. To run all the demos, you might have to install some other packages, e.g. scipy or pyaudio, but those are note required for normal usage.

Xcode is only needed, if you want to build the GR framework from source.

[HermenB]

Thank you, this worked! I am currently trying out some of the demos and so far, so good! Sometimes it seems not to work, but after a kernel restart it does. Thank you very much for your patience with helping me out.

kind regards,

Hermen

ps: do you know where best to get pyopencl? I couldn't find it on Anaconda.
