Reading LAS file from http(s) URIs

[gsakkis]

When running PDAL installed via Conda I can access remote http(s) LAS files:

$ pdal --version
--------------------------------------------------------------------------------------------------------------------------------------------------------------------
pdal 2.2.0 (git-version: 65c8de)
--------------------------------------------------------------------------------------------------------------------------------------------------------------------

$ pdal info --summary http://data.entwine.io/red-rocks.laz | jq keys
[
  "filename",
  "now",
  "pdal_version",
  "reader",
  "summary"
]

When building from source it tries to parse it as a local file:

$ pdal info --summary https://data.entwine.io/red-rocks.laz
PDAL: pdalboost::filesystem::file_size: No such file or directory: "https://data.entwine.io/red-rocks.laz"

So I'm guessing it's missing a library or a build option but looking at the dependencies I don't see anything obvious (e.g. curl is available).

This works for me on OSX conda.

I believe PDAL tries to write to /tmp as its working location when fetching remote data. Could it be that it can't write there on your system?

Can you please provide the output from cmake configuration?

I checked, /tmp is writable by all.

This was broken by #3226. I'll try to fix soon
