[pdal] Building PDAL 1.3 on Debian testing

[Jean-Francois Prieur]

Hello,

I know I can use Docker ;) but I am learning how to build applications from
source. I saw that there was a PDAL 1.2 package for Debian testing but it
is not built with PCL so it does not have the ground filter that I need. As
an aside, if I install the PCL package before the PDAL package, will it
then be linked? I do not think so, believe it has to be packaged with the
support built in.

I followed the instructions on the PDAL website (after installing the PCL
(and others) package and I can access the PDAL command line eg. --version
returns 1.3 and --drivers shows that the filter.ground is available.
However there are some errors at the top of the display such as:

(PDAL Error: 0): Can't load library
/opt/source/pdal-trunk/build/bin/../lib/libpdal_plugin_filter_gridprojection.so:
Failed to load

The are two other filters that have these errors when I invoke PDAL

libpdal_plugin_filter_greedyprojection.so
libpdal_plugin_filter_poisson.so

I assume I missed a dependency somewhere or something similar. I even
sourced the paths before running PDAL with the following

export LD_LIBRARY_PATH="/opt/source/pdal-trunk/build/lib:$LD_LIBRARY_PATH"
export PATH="/opt/source/pdal-trunk/build/bin:$PATH"

but I get the same errors.

This is on Debian stretch 64-bit.

Thanks for any illumination you can provide as to what package I forgot.

I do not think these errors are blocking (I do not need those specific
functions) but am worried something else might be broken under the hood.

Regards,
JF Prieur
