I am trying to subscribe to a topic, namely nav_msgs::Odometry. subodom = nh_.subscribe<nav_msgs::odometry> ("RosAria/pose", 1, &SensorSonar::callback, this); Strangely I get this error message: Description Resource Path Location Type Symbol 'subscribe' could not be resolved libSENSOR.h /mmrprojekt/src line 79 Semantic Error

Just one line bellow I subscurbe to another Topic without any problem. sub = nh_.subscribe <sensor_msgs::pointcloud> ("/RosAria/sonar",1, &SensorSonar::callback, this);

Any ideas?

You are using the same callback for both subscribes. I would guess, that the parameter only fits one of those, so that the signature of the templated method does not match the given callback.

Arg yes I changed it shortly after writing this question. I was too blind :-) Thanks!

Ops sorry. I clicked the green checkbox to the left. Is that all I have to do? :-)
