trouble with isExpired()
I can not figure out how to use isExpired function from actionlib. The first line is what the documentation tells me to use. spotted is my action name and marker is the package its located in. The second line is what I think is right, but I can't get it to compile (with spottedAction, spottedActionGoal, spottedGoal).
actionlib::ClientGoalHandle<ActionSpec>::isExpired()
actionlib::ClientGoalHandle<marker::spotted.....>::isExpired()
Thanks :)
when using actionlib::ClientGoalHandle<marker::spottedAction>::isExpired()
Errors << control:make /home/ros-industrial/ros_ws/logs/control/build.make.009.log /home/ros-industrial/ros_ws/src/nov_ros/control/src/nodes/seq_node.cpp: In function ‘int main(int, char)’: /home/ros-industrial/ros_ws/src/nov_ros/control/src/nodes/seq_node.cpp:206:91: error: cannot call member function ‘bool actionlib::ClientGoalHandle<actionspec>::isExpired() const [with ActionSpec = marker::spottedAction_<std::allocator<void> >]’ without object if (actionlib::ClientGoalHandle<marker::spottedaction>::isExpired()) { ^ make[2]: [CMakeFiles/seq_node.dir/src/nodes/seq_node.cpp.o] Error 1 make[1]: [CMakeFiles/seq_node.dir/all] Error 2 make: * [all] Error 2
Can you please update your question with the errors that you're getting (using the preformatted text (
101010) button)I figured out the 101010 button too late. when i use spottedAction, i get "
cannot call member function 'bool actionlib::ClientGoalHandle<actionspec>::isExpired() const' without objectwhen i use spottedActionGoal, i get
required from hereno type named '_action_goal_type' in 'struct marker::spottedActionGoal_<std::allocator<void> >'and a whole bunch of other "no type name...".
when I use spottedGoal, i get the basically same thing as using spottedActionGoal
Can you please post with full error?

Please don't use comments to give more information, please update your question instead
The problem is you're trying to call the method as if it was a static method without an object instance. You need to call this on an actual instance of
actionlib::ClientGoalHandle
