This will not work (or show hidden errors) as they are likely not
version compatible (GDAL 2 vs GDAL 3).

Yes, if the softlink was in place then it is expected.

ok, so you need to compile probably in this order:

- proj
- geotiff
- (other GDAL dependencies)
- gdal
- liblas (maybe outdated)
- pdal
- grass

There is an open pull request for  GRASS core:

"r.in.pdal - PDAL-based version of r.in.lidar"
https://github.com/OSGeo/grass/pull/61

As a workaround, there is an addon:
https://grass.osgeo.org/grass7/manuals/addons/r.in.pdal.html

which just requires the PDAL binary to be running.

Markus
