[PD] [flext] Inheriting access to variables declared once in a library

Hi,

I'm currently using flext to develop a library of externals itself wrapping another C++ library. On the latter library, some setup classes have to be instanciated once only in a whole application. What's the way to benefit from inheritance in order to:

• declare instances of those setup classes only in the base flext class of the

library in order to create each only once;

• share access with externals, being flext inherited classes of the base class?

As I'm a poor C++ coder, the only ugly way I've yet found to circumvent this is declaring instances of those setup classes outside flext classes, statically. But for sure those variable won't get deleted and Pd sends a "read memory" error message when it's being closed...

Any idea?

Thanks, Christian
