Re: [Gems-users] Error loading module 'ruby'

["Mike Marty" <mikem@xxxxxxxxxxx>]

I'm not sure what the problem is.  ruby_session_set is defined in 
$GEMS/ruby/module/ruby.c.  This is the file, the only one, that is handled 
by the Simics module creation process (the last stage in the build).
I looked at one of my built modules and ruby_session_set is definitely 
defined (T instead of U).
Do _all_ the functions in ruby.c show up as undefined?
