Getting errors during the catkin build

[gforestier27]

I'm getting theses errors when entering catkin build maplab ov_maplab ov_data -j4 into the docker.

Solved by doing a catkin clean, and then doing catkin build maplab before the command above.

Hello, I had the same issue and doing catkin clean then catkin build maplab didn't solve it for me. I had to add the following lines of code to "maplab/backend/map-resources/src/resource-conversion.cc" line 590:

template <>
void addLabelToPointCloud(
    const uint32_t label, const size_t index,
    resources::VoxbloxColorPointCloud* point_cloud) {
  CHECK_NOTNULL(point_cloud);
  DCHECK_LT(index, point_cloud->points_C->size());
}

This is just to be able to build, It doesn't perform anything inside but some checks, I do not know who is trying to call this function.
