Hi Laura,
Thank you for your suggestions. I made progress with your suggestions,
but there are still some problems.
I commented out the xps_library portion of my matlab startup script.
Indeed, now I am able to open the tutorial 3 model file without a
segfault. I see the yellow blocks show up as "bad links". I can delete
them. I looked at the original .mdl file in a text editor and saw what
I need to add. I addpath the xps_library area to the matlab path. This
next step took me a while to figure out (maybe it is obvious to others).
Inside the simulink library browser I had to go to View->Refresh Tree
View (or F5) to have simulink catch the newly added xps_library. I add
appropriate yellow blocks. I can save this new model file.
But when I edit back the xps_library into the startup script and restart
sysgen, and open the newly saved tutorial 3 file, I segfault again!
So I decide it is a pain in the neck, but I can go through adding the
xps_library path by hand each time to be able to open this model. So I
commented out the xps_library in startup, manually addpath and refresh
tree view after opening model. The model is all there now. So I want to
compile the model, and I run bee_xps, and press the Run XPS button, it
fails with the following message:

Any ideas?
