When Flexus starts up, the MagicBreak component attempts to
identify the console object in Simics and connect to it. This feature
allows Flexus to stop the simulation when a certain string is printed to
the system console via the "console-tracker.add-break-string" command.
Apparently, the RedHat 7.3 checkpoint from Virtutech does not have an
Xterm console object, or that object works differently than in SPARC
systems. The particular error message you are seeing is actually coming
from Simics - we implement our console tracker by using the "break_string"
attribute of the console object, and Virtutech's implementation of that
attribute is throwing this error.
The quick workaround for this problem is to comment out the code in the
MagicBreak component that enables the console tracker feature. The
relevant lines are MagicBreakImpl.cpp:237-240. I reproduce them here:
boost::intrusive_ptr<ConsoleStringTracker>
con_tracker(BreakpointTracker::newConsoleStringTracker());
theTrackers.push_back(con_tracker);
theConsoleStringObject = theConBreakFactory.create("console-tracker");
theConsoleStringObject->setConsoleStringTracker(con_tracker);
If you comment these lines out, I believe the error will disappear.

Thanks Tom for the updates.
Actually I tried commenting out the lines but unfortunitely I
still have the same "Xterm_Break_String" PROBLEM, should I look
somewhere else in the code and comment out the lines related to
this.
Also this lead me to the question, do you think using CMPFlex-x86
with x86 instead of ultraSPARC III cause a problem during the
installation. Also One more question, should I strictly do the
checkpointing and run the interactive script as mentioned in the
tutorial, or I can do it manually by writing my own checkpoint and
then load the flexus module in simics using load-module command.
THANKS
SHADI
