Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

And is there any way to interact with GPIO with a script C++ or Python?

Exec format error perhaps means that the binary was not built for ARM.

As for the interaction - I guess you can use Raspberry Pi's GPIO C++ library.

To compile UE4 for linux, should i select developement or developement editor?

avatar image Oneil974 Nov 12 '15 at 01:55 PM

Ok, it was really a problem with compilation. Now I'm compiling for ARM fine but I'm getting an OpenGL 3.2 error when running project. Can you tell me more?

What hardware are you trying to run on?

I'm trying to run on raspberry pi 2. Can we only run dedicated server?

Yes, dedicated server only. Running other targets requires desktop GL support (not GLES) - among ARM boards only Jetson TK1 / TX1 have that.

A new version of Raspbian is now avaible and including OpenGL support with new "VC4 Open Source Driver" for the broadcom GPU. Assuming for the moment it's experimental, do you think it could change something?

Otherwise, some Webgl test like threejs appear to be running pretty well. Maybe a web version could run...
