Could you please explain in detail how to make a topic and message readable by ROS2?
I want to visualize another ros message in RViz,

I add rt/ in front of the topic
I use default Qos,

I used rtiddsgen with c++11,
I can see topic in ROS2

However when I echo the topic to see message
ros2 topic echo /topic_name

I got an error
The passed message type is invalid.

Thanks in advance

Hi,

I have RTI Connext DDS pro 6.1.0,
I am using Ubuntu 18.04 x64

When I try to build Makefile_x64Linux3gcc5.4.0, I got a lot of errors like:

RTILog_debug’ was not declared in this scope

Thank you for your help

I am using opencv to read camera image/saved image, and I am confused how to pass the image to the instance.

Eg:
#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
#include

using namespace cv;
using namespace std;

Mat image;
image = imread(argv[1], CV_LOAD_IMAGE_COLOR); // Read the file

if(! image.data )                              // Check for invalid input
{
    cout <<  "Could not open or find the image" << std::endl ;
    return -1;
}

from the rti-dds code:
/* Get a new sample before every write. This data sample can come from a
free sample or a previously written sample which is ready for reuse. */

    retcode = CameraImage_CameraImageData_writer->get_loan(instance);
    if (retcode != DDS_RETCODE_OK) {
        fprintf(stderr, "CameraImage_CameraImageDataDataWriter_get_loan error(%s:%d)\n", __FILE__, __LINE__);
        publisher_shutdown(participant);
        return -1;
    }

how do provide this image/image properties to instance?
