I am following the Simple Interactive Marker tutorial and I try to visualize all the information I can get from the pointer. But catkin_make complains the function is not existent, but the class template says otherwise. Headers and package.xml and cmakelist should be ok.
How to go from here:

 void processMarkerFeedback(const
                           visualization_msgs::InteractiveMarkerFeedbackConstPtr
                           & feedbackPtr)
{
  unsigned char buff[1000];
  feedbackPtr->serialize(buff);// fail
  printf("%s\n", buff);

catkin_make says

error: ‘const struct visualization_msgs::InteractiveMarkerFeedback_<std::allocator<void> >’ has no member named ‘serialize’

I use kinetic, and it looks like they dissolved the header file InteractiveMarkerFeedback.
Cannot locate it anymore. Basically it was only about (de-) serialization.

Probably to reduce src files, the new interactive marker definition is here.

I don't know if this is the issue, but the class template that you link to is from hydro. What version of ROS are you using?

I'm using indigo, which apparently also has serialize and deserialize methods (which I didn't know, so thanks!). I don't know if jade or later retain that API for messages, so that's something to check.
