Hi all,

I would like to save some points cloud from my kinect using the rosbag, but when I'm just trying to do basic write and read rosbags (not even point cloud) like in this tutorial, I've got this error undefined reference to rosbag::Bag::Bag() and it's for the declaration of my rosbag rosbag::Bag bag.

Maybe it's the way I'm using it (in the main of my node), I really don't know. I did the include of rosbag/bag.h (and rosbag/view.h but not really useful yet) and I don't see what the problem, I'm pretty sure it's obvious so forgive me.

When I'm reading the CookBook or Code API I don't understand how I should use the rosbag in my code.

Thank you for your help,

It seems like your linker flags do not include rosbag. Just add

<depend package="rosbag" />

in your manifest.xml file.

I don't want to create a new question just for this question: Is the method open create the bag file?

because when I do (just before my while loop)

rosbag::Bag bag;"test.bag", rosbag::bagmode::Write);

    std_msgs::String str; = std::string("foo");

    std_msgs::Int32 i; = 42;

    bag.write("chatter", ros::Time::now(), str);
    bag.write("numbers", ros::Time::now(), i);


I don't have any test.bag file in my rosbag folder (I've just created)...

Thanks for your help

I think you should have created a new question for this. Answers should really be used for answering things, not for subsequent questions, not for discussion and not for comments. This is not a forum. should create a new bag. Try specifying an absolute path.
