Hey guys, hopefully you can help me out with this. I'm trying to make the dataspeed DBW package. However, when I do, I keep getting errors that it can't link ros libraries.

dbc_node.cpp:(.text+0x13a): undefined reference to `ros::init(int&, char**, std::string const&, unsigned int)'
dbc_node.cpp:(.text+0x196): undefined reference to `ros::NodeHandle::NodeHandle(std::string const&, std::map<std::string, std::string, std::less<std::string>, std::allocator<std::pair<std::string const, std::string> > > const&)'
dbc_node.cpp:(.text+0x21b): undefined reference to `ros::NodeHandle::NodeHandle(std::string const&, std::map<std::string, std::string, std::less<std::string>, std::allocator<std::pair<std::string const, std::string> > > const&)'
dbc_node.cpp:(.text+0x2a1): undefined reference to `ros::NodeHandle::getParam(std::string const&, std::string&) const'
dbc_node.cpp:(.text+0x338): undefined reference to `ros::console::initializeLogLocation(ros::console::LogLocation*, std::string const&, ros::console::levels::Level)'
dbc_node.cpp:(.text+0x447): undefined reference to `ros::console::initializeLogLocation(ros::console::LogLocation*, std::string const&, ros::console::levels::Level)'

They don't explicitly say they support lunar, but it doesn't seem like it's something that should be causing a problem. Does lunar require a different way of being linked or is there some other steps I can take. (Short of uninstalling lunar and going back to indigo or kinetic)

Thanks guys

Apologies: https://bitbucket.org/DataspeedInc/db...

(I had it there, but after signing in I had to rewrite the post. Guess I forgot it then.)

I've checked the repository, but at least in the default branch I cannot find a file named dbc_node.cpp. Can you check that is the correct repository?

It's under src/dataspeed_can/dataspeed_can_tools/src/

stridera@fluttershy:~/dbw$ find . | grep dbc_node.cpp
./src/dataspeed_can/dataspeed_can_tools/src/dbc_node.cpp
./build/dataspeed_can/dataspeed_can_tools/CMakeFiles/dbc_node.dir/src/dbc_node.cpp.o

It's under src/dataspeed_can/dataspeed_can_tools/src/

Which is not part of the repository you linked to, but of another, different repository.

I think this would be something to report over at DataspeedInc/dataspeed_can/issues, as this is a build error, not a usage problem.

It might be that they were depending on one of the libs transitively brining in the symbols that are mising.

Yeah, I was going to do that but figured I would ask first to make sure it wasn't an issue with my setup. Thanks for your help!

I don't know whether it is an issue with your setup, but I would still report it over there.

If/when you open an issue, please post a link to the issue here on ROS Answers, so we keep things connected.
