hello,I need you some help ,thanks.

It doesn't continue ,when run this program to this progress. Why??? Can you give me some help? Thanks .

where is the "transformations"?

Thanks a lot for the code you uploaded! Recently, I am learning the implement of A* algorithm on ROS. But the code occured an error. where is the "transformations" file or library? I need the help from you! Thank you!
