Hello all, The following question may not be related to boost, but if a solution can be found with boost or otherwise would be great. I've a base class with a function template. I derive from base class and try to have a specialization for the function template in derived class I did something like this. ////////////////////////// Header file begin ////////////////////////// class Base { .. template <typename T> fun (T arg) { ... } }; class Derived : public Base { ... } ; template <> Derived::fun(int arg); ///////////////////////// Header file end //////////////////////////// and in .cpp file I've provided implementation for the template specialization. This works fine with MSVC 8.0 and g++ complains about lack of function declaration fun in Derived class. I do not know which compiler is behaving correctly. Any help in this is greatly appreciated. Thanks in advance, Surya
