Hello, I compiled my code using catkin_make, and some linking errors popped up. There are no problem with the compiling this time, just the linking. Here are half of my linking error log:
Scanning dependencies of target subscribe_to_pose [ 50%] Built target pubvel [100%] Building CXX object tj_ev3_drive/CMakeFiles/subscribe_to_pose.dir/src/subscribe_to_pose.cpp.o Linking CXX executable /home/robot/devel/lib/tj_ev3_drive/subscribe_to_pose CMakeFiles/subscribe_to_pose.dir/src/subscribe_to_pose.cpp.o: In function

Thanks.
