Hi Alex,
thanks for reworking bigger parts of the processing SAGA provider!
Really appreciated.
I am writing you as the maintainer of the ports of SAGA GIS and QGIS for
the FreeBSD OS[1][2].
For some reasons, we don't package our system with different versions of
SAGA GIS. Recent FreeBSD comes with SAGA GIS version 3.0.0, I am working
on an update to version 4.1.0.
With your latest updates to QGIS (r413c6e5), newer versions of SAGA GIS
than 2.3.x are not recognized any more :(
I am familiar with the background, that QGIS processing only garantees
to work well with the SAGA GIS LTR version. But there was a kind of
tacit agreement for several years now, that QGIS processing tools also
accepted to display (and somewhat work with) newer SAGA GIS versions.
A user of QGIS, who had installed a more recent SAGA GIS version, worked
on his own risk, and of course it was not garanteed to work flawlessly.
But, nevertheless it worked for many cases.
Now my request: It would be fine and at least important for FreeBSD
users, to have the possibility to use SAGA GIS > 2.3.x with QGIS 2.18.9
again.
As far as I can see, getSagaInstalledVersion() within
python/plugins/processing/algs/saga/SagaUtils.py does find the correct
version, even if it is greater than 2.3.x (the trunk version in my case):
>>> getSagaInstalledVersion()
'5.0.0'
findSagaFolder() gives nothing back, I think, this is one main cause for
not displaying any SAGA GIS presence here.
Another reason could be, that line 76 in SagaAlgorithmProvider.py checks
for 2.3. ('hardcoded'):
l76: if not version.startwith('2.3.'):
I would really appreciate any changes, that would make it possible again
to work with newer SAGA GIS versions, even with devel versions.
Thanks for any hints and/or changes. Please let me know, if I could test
something.
Best wishes,
Rainer Hurling
