[Help-gsl] vegas function in another class

[Chandra Shekhar Sah]

Hi,
I am trying to use vegas integration inside my class. 
I defined the integration function inside my class:
------------------------------double MyClass::funs(double *k, size_t dim, void 
*params){....................
}
double MyClass::getInt(int b)
{struct my_para bb;bb.b = b;
gsl_monte_function G = {this->binFun, ndim, &bb};


}-------------------------------
I am getting compilation error in "gsl_monte_function G = {this->funs, ndim, 
&bb};" line. The error is error: invalid cast from type ‘double 
(MyClass::*)(double*, size_t, void*) {aka double (MyClass::*)(double*, unsigned 
int, void*)}’ to type ‘double’

Any suggestion? Thanks.Chandra
