ok, thanks. Based on that thread, I guess the question (short term) is: is it possible to run the 32 bit port on my mac book pro (core 2 duo) machine ? (If I remember correctly, I don't think so b/c the Java 6 JRE is 64bit and doesn't like the 32bit libs)
If not, I can always do the dev on my amd64 gentoo box ;)
In any case, let me know if/when I might be useful. On Jul 2, 2008, at 1:26 PM, Carolyn MacLeod wrote: Please read bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=239301. Carolyn Yep, I took out the other arch-s and it is x86_64 that dies. Thanks for the info. I'll start looking at that stuff this week(end).
