I am trying to use the convolution library in pcl (point cloud library). The page for the Gaussian Convolution page is here. It quotes the following include for this library:

#include <pcl/filters/convolution_3d.h>

But when I include the above file I get the following compile error:

fatal error: pcl/filters/convolution_3d.h: No such file or directory

Other includes from the filters file like:

#include <pcl/filters/radius_outlier_removal.h>
#include <pcl/filters/conditional_removal.h>

Works just fine, so why does the convolution library not work?

    That functionality is only in the trunk version (1.6), so this could be explained by only having the 1.5.1 version installed, or possibly not having the right -I/-L flags for the compiler to see the trunk version first, assuming you have both installed.
