[pdp-discuss] ta-iv question

[Brad Aisa]

Hi Richard,

In general, you can add things to the classes, or inherit and add new 
things, and stuff should Just Work.

I am suspecting the problem in this case is that the bp dynamic 
library was updated, but the code that it had been previously linked 
to may not have been recompiled, resulting in a runtime mismatch -- 
the dependency information in our makefiles may not always be 
complete. See the user manual section for programmers, where it 
explains the various make options, and do a make clean then rebuild 
all and see if that works.
