boost :: bind用于模板类中的非静态成员函数

Question

template<typename T> class testClass{
    public:
    bool compare(const int& a, const int& b){
        T x;
        ....
    }
    void sort(){
        std::sort( data.begin() ,
                data.end() ,
                boost::bind<bool>(
                &testClass<T>::compare,
                this, _1 , _2 ) );
    }
    std::vector<int> data;
}

I have a template-d class with a non-static member function intended as comparator for std::sort . The comparator depends on the typename T parameter. As it has an implicit this pointer I try to boost::bind the pointer this to it.

Yet neither boost::bind<bool>(.......) nor boost::bind(....) would compile.

The example above fails on MSVC 2008 (as I'm on a non-English environment I'm not sure about the exact message in English, but probably complaining about either prototypes could make all necessary conversions of arguments feasible.)

Well, after quite some digging... The problem indeed does not lie in the snippet presented above.

Turns out to be an issue similar to ( Strange VC++ compile error, C2244 ) in another member function related. A function called in compare happened to be a template function that failed to compile exactly like the one in the above question. I didn't notice THAT error at first.

I moved parts of code from class.cpp to class.hpp and now it works.

A stupid MSVC bug, and a stupid mistake I made.
