Hi, Alec, I suspect your MLIB_DEVEL_PATH environment variable is not getting set. This error message...
> An error or warning occurred during a callback while saving > '/casper_library/casper_library_bus.slx'. …shows that matlab is trying to save the casper_library_bus.slx file in "/casper_library" (i.e. one level down from the root directory). I suspect that’s not really where you’re mlib_devel lives. The matlab code that writes this file is shown in this part of the error message... > Error in casper_library_bus_init (line 285) > filename = save_system(mdl,[getenv('MLIB_DEVEL_PATH'), > '/casper_library/', 'casper_library_bus']); As you can see, if "getenv('MLIB_DEVEL_PATH')" returns an empty string, the the file name which will be used is "/casper_library/casper_library_bus" (plus any extension that gets added by matlab/simulink). This is the path that is being used (see previous error message) so that indicates that MLIB_DEVEL_PATH is not being set in your environment (or maybe set but not "exported"). I think this is supposed to happen automatically as part of the "startsg" script. HTH, Dave
