I am trying to compile NPAPI plugin under Win-XP and VS 2008.
Its giving me error as nsScriptablePeer.obj : error LNK2019: unresolved external symbol _NPN_Evaluate referenced in function when I try to use NPN_Evaluate to call javascript function . I have added all libraries from xulrunner-sdk/lib and xullrunner-sdk/sdk/lib in additional library directories. Is there any other library needs to be included to use NPN_Evaluate function ?
The functions beginning with NPN_ are only accessible through the pointer passed during the initialization NP_Initialize phase. I've been caught by this situation and I decided to document a bit here.
In other words, you don't have to link a library but you have to catch the pointer to the NPN browser functions during the NP_Initialize call to your plugin.
