Somehow this was garbled when sent throughout the news group, so I'll resend.

I've created a subclass of a pfDCS node similar to the example in the
Performer Programmers Manual.

#include <Performer/pf/pfDCS.h>

class Aircraft: public pfDCS{

protected

public
  Aircraft();

};

I create a DSO file after the compile so that it will link at runtime. It
compiles fine, however, at runtime I get an unresolved symbol call from rld.

rld: Error: unresolved symbol in ./lib/libaircraft.ogl.n32.so:
_vtbl_8Aircraft

I'm using Performer 2.0.2 (patch 1392 installed) on an R10000 O2. If I
remove the ":public pfDCS" (I'm not using any pfDCS functionality yet), It
compiles and runs fine. Is there a header file or patch I'm missing? Thanx.

Jim
