Processing on Linux
Jun 25th, 2007, 3:42am  
Hello everyone,

I'm wondering if anyone here is running Processing on Linux?

I can run the IDE and my sketches fine, but everything is painfully slow.  Sketches that I wrote 3 years ago are blazingly fast on my computer when running Windows, but crawl down to a few FPS under Linux.

I'm running Ubuntu Feisty 7.04 with Sun's Java JRE build 1.6.0-b105.  I also tried the JRE that came with processing-0124 and Blackdown Java, both of which are even slower.

As a side note, I can run regular graphics-intensive applets  which have been written in straight up Java with good performance.

Any thoughts or suggestions?..

Thanks!
David.

i use ubutu 7.04 to test the linux versions but haven't seen this problem.

a related (or identical) problem was filed here as a bug:
http://dev.processing.org/bugs/show_bug.cgi?id=93

if you have anything that can be done to replicate it, i'd be interested in getting it to work. i'm not sure what would be causing the trouble.

Quick bump, as I've been playing with this quite a bit...

I've seen Ubuntu get a little finicky about actually using the current version of Java. Check java -version to be sure. Even then, it's possible that somehow it's targeting the wrong version. I'm currently compiling all my sketches from within Eclipse, and from there it's easy enough to recompile Eclipse itself to make sure you use Java 1.6. For me, it's super fast -- fast enough to outrun the poky Mac JVM, for sure, on a much slower machine.

Anyway, Google "installing Java 6 Ubuntu" and you'll find some helpful advice for making sure it installs correctly.

I hope we get better Java installs, and in general Java becomes less of a second-class citizen on Linux, because it really is a terrific Java platform once you get everything set up. And yes, those non-Sun, older Javas are absolutely hideous, so I think they've unfairly tainted the platform's reputation.
