cloudcompare.CloudCompare -SILENT -C_EXPORT_FMT LAS -o <FILENAME> -SS RANDOM 500000

This is what I hit on the CommandLine with the snap installed:

Code: Select all

cloudcompare.CloudCompare -SILENT -C_EXPORT_FMT LAS -o export_4326_points.laz -SS RANDOM 500000

Now trying a snap of CloudCompare.

Almost a victory?

Code: Select all

$ cloudcompare.CloudCompare

You should enable snap support in Pamac preferences to see snap packages

Thanx @CloudyCloud for the suggestion but I am confused.
In a previous post you said, "Why don't you install the official release version instead of compiling from AUR?"
But even with SNAP turned on in Pamac, I do not have an official release beyond AUR, SNAP or Flatpak.

Then in another post I shared that I could not SAVE in LAS or LAZ on one of the SNAP/FLAT versions.

Could you explain what you see for the "official release that you use successfully?

Currently, this is what I have, which mirrors what you have, I think:

Yet, when I try to open it I get a quick icon, and then it goes away; the app never starts visually.
I get this icon, and then it goes away.

Thank you for the help.

Try launching it from a console and see what errors you get. Execute command: cloudcompare.CloudCompare
