CloudCompare can't read LAS on Jammy

[Pierre Abbat]

I have two computers running Linux here. I upgraded one to Jammy; the other one is still running Focal. I tried to open an LAS file in CloudCompare on Jammy and found that it didn't recognize the file type. I ran "ldd `which CloudCompare`" on both computers and found that the one on Focal is linked with libpdal_base.so.9, whereas the one on Jammy is not linked with PDAL, though a later version of PDAL is installed.

It turns out, however, that reading LAS on the latest version of CloudCompare is done by a plugin, which links with LASzip, which also is installed. See http://www.cloudcompare.org/forum/viewtopic.php?f=9&t=6242 .

I am a land surveyor and develop software that processes point clouds in LAS format, which are used by land surveyors for topographical surveys. I need to upgrade my computer to compile another program, but can't until I have CloudCompare reading LAS files on Jammy.

This is about a deb package, not a snap package.

Maybe one of these?

I guess you'll want to apt-get source cloudcompare and patch it.
Maybe you want to try the experimental version from Debian? Or just switch to the older
version that works, then apt-mark hold cloudcompare to keep it.

Please provide example input file.

Here's a small LAS file, a test file produced by one of my programs. CloudCompare on Focal reads it fine, on Jammy it doesn't recognize LAS at all.

Set back to New

Hi Pierre, sorry for the late reply. For some reason I don't get a mail or notification for updates. You might want to reach out to me on IRC (tarzeau or tarzeau_) or matrix. I'll try to test your example file tomorrow and post further results.

I can confirm opening of

5779.las: LIDAR point data records, version 1.2, SYSID TEST, Generating Software Wolkenbase 0.1.2~alph

fails.
