I have some plugin in working very well up to including 4D16 but they do not work on 4D17.
First message was “L’exécutable n’a pu être chargé”; the answer was easy to find, they were compiled 32bits.
I recompile one of these plugin in 64bits; that did not work better, I received the message “Version incompatible (non étendue). Vous devez mettre à jour votre plugin”
The question is what parameters do I have to change in xCode to become “extended”?
