Pdal : bug with "ground" function - Gdal not recognized (can't find "classify")

[Mathvarin]

Hello,
I followed the first exercices with the docker toolbox (https://www.pdal.io/workshop/exercises/analysis/ground/ground.html) and everything worked fine. When I arrived at the "ground" function, I got this message :

"PDAL: filter.pmf: Unexpected argument 'classify'.
(pdal ground Dbug) GDAL debug: GDAL: In GDALDestroy - unloading GDAL shared library"

Is anyone has an idea of the problem?

Thank you very much

Mathieu

Duplicate of #1565.

Actually, @abellgithub this is a legit bug in the kernel, which is still trying to set the classify and extract options on the filter. I'll fix it up.

In the meantime @Mathvarin, you can always perform your processing as shown here in the second example, with or without the outlier and range filters. Additional pmf documentation can be found here.

Thank you @chambbj I will try that.

The second example worked fine.
