I have been trying to Make/compile a c++ file and have been receiving these errors. g++ -c grabberDCS.c++ -I/usr/local/CAVE/include -O grabberDCS.c++: In member function `void grabberDCS::GetWandMatrix(pfMatrix&)': grabberDCS.c++:72: error: syntax error before `||' token grabberDCS.c++:73: error: `pos' undeclared (first use this function) grabberDCS.c++:73: error: (Each undeclared identifier is reported only once for each function it appears in.) grabberDCS.c++:74: error: syntax error before `||' token grabberDCS.c++:76: error: syntax error before `||' token grabberDCS.c++:77: error: syntax error before `||' token grabberDCS.c++:78: error: syntax error before `||' token grabberDCS.c++: In member function `void grabberDCS::GetInverseWandMatrix(pfMatrix&)': grabberDCS.c++:84: error: syntax error before `||' token grabberDCS.c++:86: error: syntax error before `||' token grabberDCS.c++:87: error: syntax error before `||' token grabberDCS.c++:88: error: syntax error before `||' token grabberDCS.c++:89: error: syntax error before `||' token make: *** [grabberDCS.o] Error 1 Can anyone help me understanding what might be the problem? The Header file grabberDCS is as below: #ifndef _grabberDCS_h_ #define _grabberDCS_h_ #include <Performer/pf/pfDCS.h> #include <Performer/pr/pfType.h> class grabberDCS : public pfDCS { public: grabberDCS(void); virtual void grab(void); virtual void release(void); virtual int isGrabbed(void); virtual int app(pfTraverser*); virtual int needsApp(void); private: int grabbed_; pfMatrix grabMat_; void GetWandMatrix(pfMatrix&); void GetInverseWandMatrix(pfMatrix&); /* Stuff required to make this a Performer class */ public: static void init(void); static pfType* getClassType(void){ return classType_; }; private: static pfType* classType_; }; #endif

Those aren't OpenGL related errors. But the errors are inside grabberDCS.c++, so check that.

Not OpenGL but no big.

You're looking at and giving us the wrong file though. Check/post the .cpp file, not the .h
