[GRASS-dev] Fwd: [PROJ] PROJ 6RC2

[Markus Neteler]

Hi devs,

there is some discussion about packages that need to be patched to use
proj_api.h or proj.h which will no longer be available in recent PROJ.

Is there anything to do in GRASS GIS (trunk)?

thanks

For the parts I maintain (with a lot of double quotes around """"maintain""""
for some of them),

- GDAL master / 2.5.0dev, to be released around May this year will require
PROJ 6 (GDAL 2.4 should probably already work fine with PROJ 6, since it uses
proj.h, but I didn't test)

- libgeotiff master / 1.5.0dev, to be probably released around the same time
of GDAL 2.5, will require PROJ 6. Current versions should likely work fine
since using proj_api.h if ACCEPT_USE_OF_DEPRECATED_PROJ_API_H is defined.

- the next version of shapelib will likely see its PROJ dependency removed
(only affects the contrib area) since I don't care about it:

- the next version of OGDI will likely see its PROJ dependency removed for the
same reason (it still uses project.h)
https://groups.yahoo.com/neo/groups/ogdidev/conversations/messages/314

- regarding MapServer, no immediate plan for action as far as I'm concerned.
It uses proj_api.h so ACCEPT_USE_OF_DEPRECATED_PROJ_API_H can be used for now.
Perhaps upgrading to proj.h would be a good topic for the OSGeo code sprint
for those who can attend.
