boost - Subscriber error in ROS -



boost - Subscriber error in ROS -

this subscriber declaration followed callback function

message_filters::subscriber<geometry_msgs::point32> point_sub(*nh, "tracked_point", 1); point_sub.registercallback(&visualservoing3d::pointcallback);

the callback declaration

void visualservoing3d::pointcallback(const geometry_msgs::point32constptr& msg) { //some functions }

but next error pops up. know subscriber.

/usr/include/boost/function/function_template.hpp:225: error: no match phone call ‘(boost::_mfi::mf1<void, visualservoing3d, const boost::shared_ptr<const geometry_msgs::point32_<std::allocator<void> > >&>) (const boost::shared_ptr<const geometry_msgs::point32_<std::allocator<void> >&)’

thanks,

nagsaver

point_sub.registercallback(&visualservoing3d::pointcallback);

you need bind non-static fellow member function object instance:

#include <boost/bind.hpp> point_sub.registercallback(boost::bind(&visualservoing3d::pointcallback, p_vs, _1));

where p_vs (shared) pointer visualservoing3d object. if need/wish bind reference, utilize boost::ref(vs)

boost publish-subscribe ros
