Re: [casper] Matlab crashes with tutorial 3
Hi all. Rich Lacasse at NRAO in Charlottesville has the same problem. I also tried it on our machine in Green Bank, with the same bad results. That's three separate machines and users with the same problem. Something's wrong with this tutorial, or it is incompatible with the latest mlib_devel. Could someone have a look at it? Thanks! John Hey Gopal, One thing you can try is to start matlab without loading the yellow blocks, open the model file and add them in fresh from the library, save and return to normal usage. This will require you comment out the load xps_library portion of your matlab startup script. Start matlab, and open the desired model file. Doing this, you may be able to see the yellow blocks show up as bad links with red dashes around them. From there you can delete them, and manually add them back in from the xps library. You may need to consult the tutorial, or look at the original model .mdl file in a text editor, to make sure you set the parameters appropriately. From there you should be able to save the .mdl file, close matlab, go back to the startup file and uncomment back to the regular usage. Hopefully it opens up fine this time. If this solution works, perhaps I can write something more detailed to the wiki page for the Tutorials. Would that be an appropriate edit for the wiki? I think something stated on that page would help - we have seen several new roach users encounter this issue. Gopal, I was also strongly advised when I started out to use 11.5 and the stable release of the tools. This solution fixed the problem on that setup, hopefully it does on 13 as well. --Laura On Mon, May 7, 2012 at 12:44 PM, Gopal Narayanan go...@astro.umass.eduwrote: Hello All, I am running Matlab R2011A on a 64-bit Debian Linux System.

Re: [casper] Matlab crashes with tutorial 3
Hi all, After a fair bit of tutorial related pain on the mailist recently, I've just forked the tutorial-devel repo to https://github.com/jack-h/tutorials_devel and recompiled tutorials 1-3 with Sysgen 11.5 and the libraries in the main casper github repo. The tutorials in the 2011 directory *should* work (along with their python counterparts). Feel free to give those a go and give me a shout if you still have problems.

Re: [casper] Matlab crashes with tutorial 3
Hi Jack, Indeed, I can open tutorial 3 from your forked github location successfully without causing segfaults. I'll post if compilation of the simulink model fails. So where exactly is the problem? In mlib_devel or incompatible changes in Xilinx System Generator? Thanks!
