To Reproduce

In https://github.com/PointCloudLibrary/pcl/blob/ad2bf688b2d036fe703cd16ea6d574e453e101b2/doc/tutorials/content/sources/interactive_icp/interactive_icp.cpp#L10 replace typedef pcl::PointXYZ PointT; by typedef pcl::PointXYZINormal PointT;.

Your Environment (please complete the following information):

• OS:Windows 11
• Compiler: Visual Studio 2022
• PCL Version master.
• PCL Type: Compiled from source, but dependencies were installed using vcpkg. I ran into a compile error when trying to install pcl using vcpkg

If PCL was compiled from source or failure in compiling PCL itself:

• GPU, CUDA disabled

Possible Solution

Workaround: cast the cloud to PointXYZ before rendering.

Additional context

I am new to pcl, so I don't even know whether this is supposed to work.

The handler is instantiated here: https://github.com/PointCloudLibrary/pcl/blob/ad2bf688b2d036fe703cd16ea6d574e453e101b2/visualization/src/point_cloud_handlers.cpp#L788-L795

On Windows, PCL is always built with PCL_ONLY_CORE_POINT_TYPES defined, otherwise the binaries would get too large and the pcl_features library would completely fail to build (too many symbols for the Windows linker to handle). So the handler is not instantiated for PointXYZINormal. But you can add #define PCL_NO_PRECOMPILE at the top of the .cpp file, to make the handler implementation available to the compiler (further information here: https://pcl.readthedocs.io/projects/tutorials/en/master/adding_custom_ptype.html#adding-custom-ptype )
