Processing (on Windows): external SAGA does not work anymore #24331

Closed qgib closed 7 years ago

qgib commented 7 years ago

Author Name: Giovanni Manghi (@gioman) Original Redmine Issue: 16422 Affected QGIS version: 2.18.5 Redmine category:processing/saga Assignee: Victor Olaya


If SAGA is not installed with osgeo4w then Processing has always allowed to use and external SAGA installation by configuring the proper path in Processing configurations.

While testing the support for SAGA LTR I therefore downloaded

https://downloads.sourceforge.net/project/saga-gis/SAGA%20-%202.3/SAGA%202.3.1/saga_2.3.1_x64.zip?r=https%3A%2F%2Fsourceforge.net%2Fprojects%2Fsaga-gis%2Ffiles%2FSAGA%2520-%25202.3%2FSAGA%25202.3.1%2F&ts=1491557320&use_mirror=netcologne

uncompressed and pointed Processing to it.

Processing correctly recognizes SAGA and SAGA version, tools open and are run, but ultimately they fail. This does not happen if used SAGA ltr is the one shipped with osgeo4w. This anyway used to work as expected in the past.

For some reason, SAGA 2.3.1 io_gdal module is not loaded using SAGA from https://downloads.sourceforge.net/project/saga-gis/SAGA%20-%202.3/SAGA%202.3.1/saga_2.3.1_x64.zip?r=https%3A%2F%2Fsourceforge.net%2Fprojects%2Fsaga-gis%2Ffiles%2FSAGA%2520-%25202.3%2FSAGA%25202.3.1%2F&ts=1491557320&use_mirror=netcologne and Processing SAGA algs does not work.

Reason for not using the binaries from the saga project is that they have a lot of own dependencies, that are already included in OSGeo4W. The version in OSGeo4W is patched to allow usage of OSGeo4W dependencies (ie. ported to GDAL C-API - patches were submitted and merged upstream; https://sourceforge.net/p/saga-gis/code/merge-requests/3/). Unfortunately the new support for SAGA LTR in processing of 2.18 wasn't anticipated. This was meant to be used with QGIS3 (ie. plenty of time to spot and fix any issues introduced by this).

I also just noticed that saga-ltr installed with osgeo4w misses io_gdal completely

that was just a comment to my previous one. Like a note/reminder. But anyway your comment made be think about it, and if I must be honest I'm not totally convinced that this is expected. It is at least a change compared to previous SAGA osgeo4w installation, if I'm not wrong.

Returning to the subject of this ticket: if now SAGA that ships with osgeo4w is compiled (and not just a copy of the upstream binaries) then I guess that in processing allowing use external SAGA installations should be disabled/removed(?).

Here is PR to remove support for external SAGA https://github.com/qgis/QGIS/pull/4587.

Not sure if same should be done for 2.18, as 2.18 still supports different SAGA versions.

Not sure if same should be done for 2.18, as 2.18 still supports different SAGA versions.

I would say do it only for qgis 3, for now at least. QGIS LTR is broken on Windows (packaging issue) and I don't see anyone tacking #24332

While testing the support for SAGA LTR I therefore downloaded

uncompressed and pointed Processing to it.

Processing correctly recognizes SAGA and SAGA version, tools open and are run, but ultimately they fail. This does not happen if used SAGA ltr is the one shipped with osgeo4w. This anyway used to work as expected in the past.

Not sure if same should be done for 2.18, as 2.18 still supports different SAGA versions.

now that #24332 is fixed this can be applied also to 2.18.*
