Hi,The following code fragment is now causing problems under gcc 4.0.1 Everything is perfect under "gcc version 3.4.3" Any recommended work-arounds? ================= code fragment====================================== #ifndef __LOC_PV_FACTORY_H__ #define __LOC_PV_FACTORY_H__ line 10 --> #include "pv_factory.h" line 11 --> line 12 --> class LOC_PV_Factory : public PV_Factory line 13 --> { line 14 --> public: line 15 --> LOC_PV_Factory(); line 16 --> ~LOC_PV_Factory(); line 17 --> ProcessVariable *create(const char *PV_name); line 18 --> private: line 19 --> friend class LOC_ProcessVariable; line 20 --> static void forget(LOC_ProcessVariable *pv); line 21 --> };
GCC was incorrectly accepting this code. You should add a declaration of class LOC_ProcessVariable outside class LOC_PV_Factory, either through its include file or with a forward declaration ("class LOC_ProcessVariable;").
By the way, the correct list to ask would have been [EMAIL PROTECTED] (this one is for development "of" GCC, not "with" GCC).
