v.in.pdal build error: some PDAL 1.4.0 includes are not where the module expects them

[msieczka]

PDAL 1.4.0, Arch Linux, x86_64.

Some PDAL includes are not in /usr/include/pdal, where v.in.pdal expects them, but in the /usr/include/pdal/io subdirectory. This leads a following build error:

$ cd ~/src/grass-7.2.0/vector/v.in.pdal

The reason why:

$ locate LasReader.hpp
/usr/include/pdal/io/LasReader.hpp

$ ls /usr/include/pdal/io/*.hpp | wc -l
37

$ ls /usr/include/pdal/*.hpp | wc -l

Patch to update include statements for PDAL 1.4.0

[neteler]

I have attached a patch which solves the changes include paths.

However, I get several compilation errors with PDAL 1.4.0. Due to API changes?

Replying to neteler:

However, I get several compilation errors with PDAL 1.4.0. Due to API changes?

Yes.

[ptschrum]

I (ptschrum) assigned this ticket to myself.

[neteler]

Ticket retargeted after milestone closed

[neteler]

See r72253: v.in.pdal: change API calls to PDAL 1.6.0 (available in G7.4)

[wenzeslaus]

Assigning to myself for clarity, but should be fixed in r72253 from #3496 by felixg for 7.4. Do we need/want to backport?

Yes, please. For me v.in.pdal compilation fails in 7.2.3RC1 because of this.
