I'm created a new interface for gazebo: gz_actarray.c to manipulate robotic arm, and I'have add it to gazebo. I have modified gazebo.h and makefile.in e makefile.am in gazebo-0.6\libgazebo I have reinstalled gazebo with the new corrections and all seems to work right. I have created a new model with the new interface and i build it. When i start gazebo (or wxgazebo) i have this message: "...undefined symbol: gz_actarray_alloc..."!
 
Which are the steps to add an interface?
 
Thanks
