Hi all,
I have created a custom message for a vector of PointCloud2 with name clusterVector.msg, and inside that vector I have the following line:
sensor_msgs/PointCloud2[] clusterClouds
This message is inside one of my custom made packages Object_detection_module. Now I am trying to use this so I am doing the following:
1) I am declaring the header:
object_detection_module/clusterVector.h
2) I am instantiating an object of that type:
object_detection_module::clusterVectorConstPtr msg1;
3) I am trying to push_back a type 2 point cloud as follows:
sensor_msgs::PointCloud2::Ptr test_message (new sensor_msgs::PointCloud2 ());
msg1->clusterClouds.push_back(test_message);
Unfortunately, when I am trying to compile my code I get the following error:
error: no matching function for call to ‘std::vector>, std::allocator>>>::push_back(sensor_msgs::PointCloud2_>::Ptr&) const’

Any ideas what I am doing wrong? Any help would be greatly appreciated.
