Cloudviewer 1.3.1 assertion exception [NSUndoManager]

New post for this & I'm new to osx tool sets.

Following the example here:  http://pointclouds.org/documentation/tutorials/cloud_viewer.php#cloud-viewer
, but here is exactly what I've got to be sure:

The following source:

#include <pcl/visualization/cloud_viewer.h>
#include <pcl/io/pcd_io.h>
int main()
{
        pcl::PointCloud<pcl::PointXYZRGB>::Ptr cloud(new pcl::PointCloud<pcl::PointXYZRGB>());
   pcl::io::loadPCDFile<pcl::PointXYZRGB>("/Users/nous/Documents/capture/cloud0.pcd", *cloud);
   pcl::visualization::CloudViewer viewer ("Simple Cloud Viewer");
   viewer.showCloud (cloud);
   while (!viewer.wasStopped ()) {}
   return 0;
}

Here is the CMakeLists.txt:

cmake_minimum_required(VERSION 2.8 FATAL_ERROR)

project(cloud_viewer)

find_package(PCL 1.2 REQUIRED)

include_directories(${PCL_INCLUDE_DIRS})
link_directories(${PCL_LIBRARY_DIRS})
add_definitions(${PCL_DEFINITIONS})

add_executable (cloud_viewer cloud_viewer.cpp)
target_link_libraries (cloud_viewer ${PCL_LIBRARIES})

Then execute the following commands:
cmake ..
make
./cloud_viewer

Results in a screen with the point cloud rendered, but destroyed shortly after with the following terminal output:

How can I correct this?   pcd_viewer loads and displays clouds without issue.  Wrong lib/runtime? Why do I see objective-c here?

Thanks - Andrew

Updates:

1. pcd_viewer uses PCLVisualizer, not CloudViewer. The following source renders the point cloud just fine:

pcl::PointCloud<pcl::PointXYZRGB>::Ptr cloud(new pcl::PointCloud<pcl::PointXYZRGB>());
pcl::io::loadPCDFile<pcl::PointXYZRGB>("/Users/nous/Documents/capture/cloud0.pcd", *cloud);
pcl::visualization::PCLVisualizer viz;
viz.addPointCloud<pcl::PointXYZRGB> (cloud);//, NULL, NULL, cloud_name.str (), viewport);
viz.spin();

2. doing a grep for CloudViewer only shows usage in openni samples.  Does this suggest a dependency? Should I install open ni?
3. The web suggests this is a bug: http://root42.blogspot.com/2010/01/not-happy-with-qt-on-os-x.html
4.  Should I recompile the visualizer with carbon? or X11?

More coffee.

CloudViewer does not play nicely with multi-threaded applications. We will deprecate it in future releases, as it
doesn't have a maintainer. Use PCLVisualizer instead.

Cheers,
Radu.

Very pleased to know I'm not crazy. Thanks for this

Might want to mention something to this affect on this page.
http://pointclouds.org/documentation/tutorials/cloud_viewer.php#cloud-viewer

Wouldn't happen to have documentation on PCLViewer?  Also - what tools are people using to move through source on osx/linux platforms?

Good point. I added this to the tutorial. Thanks for the tip!

Cheers,
Radu.

Thanks, but I get exactly the same errors with this example.  It is some
basic problem with my Windows 7 installation or setup.

I just joined [hidden email] and posted this problem, so
I will wait to see if someone knows how to fix it.
