[GRASS-dev] r.tileset and cs2cs / cct

Hi,

On my Ubuntu 16.04 box I get the following error message in GRASS 7.4.1 (package install from UbuntuGIS) with r.tileset:

r.tileset sourceproj=+init=epsg:25833 maxrows=10000 maxcols=10000 | wc -l

ERROR: cs2cs program not found, install PROJ.4 first:

http://proj.maptools.org

ERROR: cs2cs failed

0

And locate tells me that there indeed is no cs2cs on my PATH/system…

Is that related to the move to Proj.5?

Can GRASS even be installed without Proj?

Is that a GRASS issue, a packaging issue or simply an installation issue?

r.tileset should probably be updated to use cct https://proj4.org/development/migration.html (yet, I cannot find cct on my system either)…

Cheers

Stefan

No, it needs libproj. However, this provides only the libraries, for cs2cs / cct you also need proj-bin (on Debian-based systems).

Yes, r.tileset should use cct if available, otherwise cs2cs.

Can you please open a ticket for this issue?

Thanks for the info.

Maybe the grass-core package on Debian should suggest installing also proj-bin (maybe it does and I just overlooked)?

Ticket opened for cct-support here: https://trac.osgeo.org/grass/ticket/3653
