[PROJ] Installing PROJ on a Mac

[Chris Marsh]

Hi,

I see you note
>QGIS 3.14
but the QGis 3.14 change notes
https://www.qgis.org/en/site/forusers/visualchangelog314/index.html
claim that QGIS 3.14 addresses that problem -- search for  Problem
reprojecting rasters in 54019 and 54042 CRSs #35512
<https://github.com/qgis/QGIS/issues/35512> in the above link

If resolving #35512 in v 3.14 and 3.16 doesn't solve the problem, I would
open a new QGis ticket.

On compiling proj:
proj is one of the geospatial libraries used by QGis and is a core library
for handling reprojection. It is something called by other programs and
isn't going to show up on the command line by typing 'proj'.
Further, the QGis will need to be recompiled against this newer version of
proj to work. Installing proj yourself separately on your computer is
almost certainly not going to bring the new features forward for the
currently installed qgis.
Compiling proj isn't going to do what you want unfortunately.

So, I would confirm this is bug is still a problem on 3.14 (and really
ensure you're trying QGis 3.16) and you aren't accidentally on 3.12.  If
it's still a problem, I would open a new ticket or post on the QGIs mailing
list '
https://qgis.org/en/site/forusers/support.html

Hope this helps,

Cheers
Chris
