Description Loïc Bartoletti freebsd_committer freebsd_triage 2018-01-17 03:13:21 UTC 
Hi Rainer,

I just saw a conflicts between math/saga and databases/grass7:
  - liblas-1.8.1_8 conflicts with liblas12-1.2.1 on /usr/local/bin/las2las

Is it possible to update liblas for Saga?

Regards

Hi Loïc,

That has been discussed in the SAGA developer list[1] several times. SAGA GIS depends on the API of liblas12 in a way, that it is not trivial to make changes towards liblas18. BTW, Debian Linux also wants to get rid of liblas12 and only use liblas18.

Citing a statement of Volker Wichmann, one of the core devs of SAGA GIS, from Dec 6th, 2017, on the list[2]

So it will take some time, until SAGA GIS leaves the liblas12 road ;(

On FreeBSD, SAGA GIS seems the only user of this old liblas12 port, as far as I can see. So in the meantime I will try to patch devel/liblas12 to rename conflicting files and dirs, like /usr/local/bin/las2las 
to something like las2las12 or include/liblas to include/liblas12. This may take some time also and I am not sure, if it will work at the end ;)

I just filed bug #225281, which should solve the conflict between devel/liblas12 and devel/liblas. 

After this patch is committed, math/saga will be adapted in a follow up.

Great! Thank you.

saga should not longer conflict with grass7, after PR#225281
