Raspberry Pi : Font Sadness
Hello,
trying to run Processing on a raspberry pi model b+ but i get an error: Font Sadness : Could not find required fonts. Please try reinstall Processing. Does anyone know how to resolve this issue?
More info:
Java 8 (JDK, Latest version)
processing-3.0b7 and Processing 3.0 - Stable

Processing requires a font to be installed on the system to be run. Is there any way to install a font on Raspberry Pi?
Ok, is see. I Replaced the Java directory in Processing with a symlink to another Java version. This version is missing the fonts that are included in the Java directory that Processing is using. I will try to move the fonts to my own Java directory.
Gottfried is working on a version of Processing that's made specifically to be compatible with the Pi. We'll probably be announcing that soon.
Ok great, would love to hear when this version is available.
It's not the latest, but could you give this version a try (comes with the right Java for ARM): http://sukzessiv.net/~gohai/p5-arm/processing-3.0b7-arm.tar.bz2
If the problem persists, please post a sketch that exhibits the issue. Thanks in advance!
hey gohai! your link does not work... would you mind to provide a working one?!
thx! :)
It's going to be released in the near future. Still polishing the bytes a bit.
oh. ok. thanks. really looking forward to it.
ive got the processing 2.2.1 running on a raspberry pi 2 b according to this tutorial: scruss.com/blog/2014/01/07/processing-2-1-oracle-java-raspberry-pi-serial-arduino-%E2%98%BA/comment-page-1/#comment-1120432
basic programs work just fine, but more "complex" programms will end up in errors: glGetError 0x500
Using the new Processing 3.0.1 linux armv6hf version i got it running on my Raspberry PI 2 B. No big problems, everything seems to be alright. Nice!
When I try to run sketches (like the rgbCube example) or other slightly more complex graphical sketches, its not running. (sometimes i do not even see the render window of the sketch) Could it be possible, that i missed some graphic drivers or something like this, or is that just a hardware issue caused by the raspberry pi, since its not as powerful as an average desktop PC? I just installed the latest java8 jdk.
Thanks in advance, Sven.
There are some more advanced 3D examples that do not run or crash. Since the Raspberry Pi's graphics drivers are binary-only, there's little we can do currently to try to debug this further, but the situation will sure improve over time with the driver maturing, and another - open source Mesa driver being developed.
Short answer: There's probably nothing wrong with your setup. Check if the Topics/Shaders/Monjori works - this normally works well on the Pi.
