I have a class algo, which has a function algo::function1 when I run this Code: alglib::minlbfgsoptimize(state, &algo::function1); It gives me the error Code: error C2664: 'alglib::minlbfgsoptimize' : cannot convert parameter 2 from 'void (__thiscall algo::* )(const alglib::real_1d_array &,double &,alglib::real_1d_array &,void *)' to 'void (__cdecl *)(const alglib::real_1d_array &,double &,alglib::real_1d_array &,void *)' May I know what went wrong?Thank you! |

That's because ALGLIB needs non-member function pointer, and you pass pointer to the member function. You have to write non-member proxy() function which calls member function of your choice, and pass this proxy function to the ALGLIB. |
