[Gems-users] Error loading module 'ruby'

[Chris Rossbach <rossbach@xxxxxxxxxxxxx>]

Hi-

I'm trying to get ruby to work in Simics 3.0.17

I believe I've followed the instructions, and I've come across an error that I 
haven't seen discussed on the user-list: everything builds OK, but when I 
start simics, (after setting SIMICS_EXTRA_LIB, reading a checkpoint, and 
setting the instruction-fetch-mode, disabling the istc and dstc) I still get 
the following error: 

  simics> load-module ruby
  Error loading module 'ruby': Failed to load module      
    'ruby' ('/d1/rossbach/gems/simics_3_workspace/x86-linux/lib/ruby.so'):
    "undefined symbol: ruby_session_set"

Even more strange, if I use nm to examine the contents of ruby.so:
rossbach@davis:/d1/rossbach/gems/simics/home/MOSI_SMP_bcast/lib$ ls
opal.so  python  ruby.so
rossbach@davis:/d1/rossbach/gems/simics/home/MOSI_SMP_bcast/lib$ nm ruby.so | 
grep ruby_session_set
         U ruby_session_set
0014cf30 T _Z16ruby_session_setPvP11conf_objectP10attr_valueS3_

I take simics error message to indicate that it was actually able to find 
ruby.so, but for some reason, it can't find ruby_session_set in the library?

Also below is the output of list-failed-modules, and a transcript of the 
entire session that leads to the error. 

Any help would be very gratefully appreciated.
Thanks in advance,
Chris Rossbach
