c++ - How to solve the error: "no matching function for call to ‘bind(<unresolved overloaded function type>" when std::bind is used in a class -

-

usually, std::bind works in boost::math::tools::bisect(). however, when tried use std::bind in class member functions, there error: " no matching function call ‘bind( "

this 1 member function of class:

    double singlecapillarytube::callocationfunctionwithoutangle(const tubegeometry &tg,                                 const fluidproperties &fp, double templocation,                                 double initiallocationvalue, double temptime,                                 const double initialtimepoint) {     auto coefficientb = calcoefficientb(tg, fp);     auto coefficienta = calcoefficienta(tg, fp);     auto coefficientd = calcoefficientd(tg, fp);     auto tempvalue = -coefficientb * (templocation - initiallocationvalue) - \                     1./2. * coefficienta * (pow(templocation, 2.) - \                     pow(initiallocationvalue, 2.)) - coefficientd * \                     (temptime - initialtimepoint);     return tempvalue; }

then function used in other member function of class:

void singlecapillarytube::callocationinterfacebisect() { stepresult = boost::math::tools::bisect(std::bind(callocationfunctionwithangle,\                                             geometry, fluids, _3, initiallocation, \                                             timepoint, initialtime), 0.0, \                                             -geometry.length, tol); }

when file compiled, error occurred. me solve problem? much:)

non-static member functions need instance called on. give that, pass this pointer first argument function. need use full qualified name of function , take address:

std::bind(&singlecapillarytube::callocationfunctionwithangle, this,           geometry, fluids, _3, initiallocation, timepoint, initialtime)

also note using _3 binds third positional argument parameter, in case first , second arguments ignored. want _1 in spot.
