I'm using Ubuntu 14.04 with pcl 1.7.1.

Try to add the following include:

#include <vtkPolyLine.h>

[jpapon]

Should I add this include to pull request #1115?

[taketwo]

Yep, makes sense.

[sotte]

Thanks for the quick reply! It works.

I'll leave this issue open till #1115 is merged.

[taketwo]

Fixed via #1115.
