[pdal] Entwine/EPT build failures

[jrmorreale_ml@enoreth.net]

Hi,

I am trying to build an EPT with entwine 2.0 (conda) on a classified lidar cloud (1220 tiles, 22billion points) but I did not succeed in getting a usable result.

The command used is :
entwine build --srs "EPSG:2154" --threads "4" --dataType "laszip" -i input_dir -o output_dir

The errors are
* Exception in pool task: writers.las: legacy flags and extended flags are not identical
* During input_xx.laz: readers.las: File signature is not 'LASF', is this an LAS/LAZ file?
* Unable to open stream for 'input_xx.laz' with error 'Too many open files'

The last error is only shown when trying to work on the 1220 files at once. The attempts have been made on the original terrascan tiles and on pdal translated laz tiles, the generated ept-data output is empty laz files.

pdal info --all of 1 laz tiles

Could you point to the mistake(s) I've made ? My aim is to publish our data online, the latest usgs example is a great incentive.
