std_msgs/Float32.h not found

edit

Hi,

I am relatively new to trying to do anything with c++ in ros, so I'm sorry if this is a stupid question.

I am trying to get AMCL to publish max weight. The plan is to publish it to a float 32 message for now when it's publishing amcl_pose, as amcl_pose checks for the particle with the maximum weight anyway. To do that, I need a float 32 message working, which is where I'm stuck. Error message:

Summary: 0 packages finished [0.62s]

I have added std_msgs as a dependancy to CMakeLists.txt, and I have added it to amcl_node.hpp as well, but nothing seems to solve the problem.

Thank you in advance.
