Cannot Define Member Function Within C++
down vote favorite 10 I am getting an error when trying to compile my code in g++ using the current signature: cannot declare member function static void Foo::Bar(std::ostream&, const Foo::Node*) to have static linkage My question is twofold: Why does it not Compile this way? What is the correct signature, and why? Signatures have always been the death of me when using C++ Edit: Here is the class header file, c++ static member function definition outside class as well: class Foo { public: Foo(); ~Foo(); bool insert(const Foo2 &v); Foo * find(const Foo2 &v); const Foo * find(const Foo2 &v) const; void output(ostream &s) const; private: //Foo(const Foo &v); //Foo& operator =(const Foo &v); //Not implemented; unneeded struct Node { Foo2 info; Node *left; Node *right; }; Node * root; static bool insert(const Foo2 &v, Node *&p); static void output(ostream &s, const Node *p); static void deleteAll(Node *p); c++ static-members method-signature static-function share|improve this question edited Nov 15 '11 at 0:33 asked Nov 15 '11 at 0:23 Joshua 1,49242246 You should include all the relevant lines from the g++ error. –Keith Layne Nov 15 '11 at 0:49 2 The error message you list can't be produced by the code you posted. There is no Foo::Bar anywhere in your program fragment. Please post a complete, minimal program that demonstrates the error you are having. A complete program is one that we can compile exactly as-is and receive the same error message as you. A minimal program is one with every line unrelated to your error removed. The code fragment you posted is neither complete nor minimal. See sscce.org for more info. –Robᵩ Nov 15 '11 at 1:08 add a comment| 1 A

My computeCivIndex() is trying to get 5 inputs from user and do a calculation and return the float value back. this.sunType is for java syntax, but for V++ what should I use to link them together if both are the same name? I have getter and setter methods in my code and also 2 constructors which is too lengthy to be posted. This is my error: test.cpp:159: error: cannot declare member function ‘static float LocationData::computeCivIndex(std::string, int, int, float, float)’ to have static linkage test.cpp: In static member function ‘static float LocationData::computeCivIndex(std::string, int, int, float, float)’: test.cpp:161: error: ‘this’ is unavailable for static member functions The code: class LocationData { private: string sunType; int noOfEarthLikePlanets; int noOfEarthLikeMoons; float aveParticulateDensity; float avePlasmaDensity; public: static float computeCivIndex(string,int,int,float,float); }; static float LocationData::computeCivIndex(string sunType, int noOfEarthLikePlanets,int noOfEarthLikemoons, float aveParticulateDensity, float avePlasmaDensity) { this.sunType = sunType; this.noOfEarthLikePlanets = noOfEarthLikePlanets; this.noOfEarthLikeMoons = noOfEarthLikeMoons; t
can we define static member function outside the class, as myself trying gives compilation error. please correct me if i've http://www.cplusplus.com/forum/general/25050/ specified wrong syntax. class A { static int count; public : A() { count ++; } static void A::countobjects (void) { cout<<"Number of objects="<
