[dtrace-discuss] Running DTrace Javascript provider on nevada

[John Rice]

Brendan - I'd like to try these out:

http://blogs.sun.com/brendan/resource/helper-monkey-0.10.tar.gz

I'm running nevada b53 at the minute with Firefox 2.0 installed by 
default. So I grabbed an old tarball of Firefox 1.5.0.4, unpacked it and 
was able to bring up firefox-bin 1.5.0.4.
http://releases.mozilla.org/pub/mozilla.org/firefox/releases/1.5.0.4/contrib/solaris_tar_ball/firefox-1.5.0.4.en-US.solaris2.10-i386.tar.bz2

I then setup the LD_PRELOAD and LD_LIBRARY_PATH to point to this 
unpacked tarball dir and fired up firefox-bin. I could then run dtrace 
-l javascript*:::* and list out the probes, but firefox failed to display.

Any ideas?
