variadic templates with template function names

Question

following this question , I am trying to avoid copy-pasting some code related to calling all of the same-named methods of the mixins of the class BaseSensor.

Answer 1

Here is another, more compact solution that compiles in C++11:

#include 
#include 

struct EdgeSensor {
    void update() { std::cout << "EdgeSensor::update" << std::endl; }
    void printStats() { std::cout << "EdgeSensor::printStats" << std::endl; }
};

struct TrendSensor {
    void update() { std::cout << "TrendSensor::update" << std::endl; }
    void printStats() { std::cout << "TrendSensor::printStats" << std::endl; }
};

template
class BaseSensor : public SensorType ... { 
    template 
    void run() {
        int arr[] = { 0, ((this->*M)(), 0)... };
        (void)arr;
    }

public:   
    void update() {   
        run<&SensorType::update...>();
    }

    void printStats() {
        run<&SensorType::printStats...>();
    }
};

int main() {
    BaseSensor bs;
    bs.update();
    bs.printStats();
}

I would be tempted to say that you don't need any structure to support the pack of pointers to member methods.
Anyway, I found that this compiles with clang and it doesn't work with GCC. I'm still trying to figure out if the code is ill-formed or if the problem is in the compiler.

I'd suggest to follow the other question to know if you can use or not this code.
