Re: Exporting graphics on a headless Pi

It might be worth noting that the process of starting a VNC session and providing a FE on the headless Raspberry Pi has been automated in the latest release (using turbovnc): In[1]:= Rasterize[Disk[]] Out[1]= -Graphics- The same limitations apply. It's slow when initializing the vnc session and Font...

Re: Mathematica with Videocore GPU

Does VideoCore have OpenCL support? If not, I'm not sure that there's any GPGPU stuff for Mathematica that would be suitable for this.

The update is currently going through QA and it includes CCodeGenerator. Should be out shortly.

Re: Raspbian init script bug

Has this init.d script been removed from newer installations? I just re-installed wolfram-engine and there is nothing related in /etc/init.d Yes. That particular script was not supposed to be present in the first place. There should be a much more robust solution for using a daemonized kernel in th...

Re: Cannot open CCodeGenerator

Ok, so this is confirmed. It appears a bug in the Raspberry Pi version of Mathematica that the CCodeGenerator package is missing. I've looked in /opt/Wolfram/WolframEngine/10.0/SystemFiles and there is no files that contain CCodeGenerator in them. I wonder who the point of contact should be for rep...

Re: Need help with "Segmentation fault"

Here are some things you might be able to try: 1) Reboot the Raspberry Pi 2) Make sure your system is fully up to date: sudo apt-get update && sudo apt-get upgrade If Mathematica is not running on the desktop but "wolfram" is working on the command line, then it's having an issue loading the desktop...

Re: Unable to install wolfram

Thanks for all the help. I appreciated. I just wanted to play with Mathematica (I have heard great things about it). Although it will be slower in softfp systems, will it still be useable? Any one knows if there are plans for such a release? We don't currently have any plans to release a softfp bui...

Re: No menu/desktop shortcuts

I'll add that line to the official debian package. So, this should be changed in the next update. Thanks for the feedback!

Re: No menu/desktop shortcuts

It's not clear to me why the lack of StartupNotify would lead to a menu icon not being populated. There are no hacks in the package installation that specify pi's home directory, either, so behavior should be the same for all users. I can check whether or not we're adhering the Startup Notification ...

Re: No more memory available

I understand why this particular function is using a lot of memory, but in this case I can't say for certain that it's ever going to work well on a Raspberry Pi Model A. For the moment, if you find yourself running out of resources, you can always have us do the calculation: weather = WolframAlpha["...
