problem converse octomap msg to octomap tree [closed]

edit

Hello there,

I'm trying an example of conversing octomap_msgs/Octomap message into a oct tree.

The Sub callback function content which I wrote is:

octomap::AbstractOcTree* tree = octomap_msgs::fullMsgToMap(msg);

But an error occurred at compile time:

undefined reference to `octomap::AbstractOcTree::createTree(std::__cxx11..........

So, am I right in writing like this? How can I solve this problem?

Thanks a lot
