Scripts cannot make reference to roscpp or rospy
Hello,
We are using ROS kinetic on a HP elitedesk 800 G2 mini (I7-6700T). Catkin doesn't work when we use any ROS functions in one of the scripts. For example for using the Joy package with a joystick it gives the following error (same error for every statement in the script):
CMakeFiles/joy_node.dir/src/joy_node.cpp.o: In function `main':
joy_node.cpp:(.text+0x70): undefined reference to `ros::init(int&, char**, std::string const&, unsigned int)'
When using the same scripts on other computers (with same ROS version) it works fine. What could be our problem? Can this be a Linux problem? We already tried to make a new workspace, reinstall ROS and adapting the CmakeList.txt according to some other questions asked on this forum.
Thanks in advance.
This is a linker error, so I suspect you're not linking to the proper libraries.
Can you show us your
CMakeLists.txt?Also: what distribution is this? Are you building ROS from source?
re:
rospy: I'm not sure I follow. That is a Python library, so there is no linking there (at least not in the way a compiled language does/need it). If you have errors specifically related torospy, please add those as well.At most you could get
cannot import ..errors I would say.
