[dtrace-discuss] Running DTrace Javascript provider on nevada

[John Rice]

Brendan - no joy :(

Did exactly as you suggested below on nevada b53 using version 0.10 of 
helper monkey and still getting a hang:

$ uname -a
SunOS jmrlaptop 5.11 snv_53 i86pc i386 i86pc

Without setting up the exports:
$ /usr/lib/firefox/firefox-bin -UILocale C -contentLocale c --> Firefox 
2.0 launches fine

Setting up exports:
$ cd~/helper-monkey-0.10/lib
$ export LD_PRELOAD=/usr/lib/firefox/libmozz.so:./libmozjs.so
$ export LD_LIBRARY_PATH=/usr/lib/mps:/usr/lib/firefox 
$ export MOZ_PLUGIN_PATH=/usr/lib/firefox/plugins
$ /usr/lib/firefox/firefox-bin -UILocale C -contentLocale c --> Firefox 
2.0 hangs

Any ideas?
