Warning message: SAGA version 7.8.2 is not officially supported - algorithms may encounter issues

[osgeokr]

What is the bug or the crash?

I'm using both QGIS 3.16.14 and QGIS 3.22.2. Whenever I run the SAGA tool, I get the following warning message: SAGA version 7.8.2 is not officially supported - algorithms may encounter issues. How can I disable this message?

Steps to reproduce the issue

That's not a bug, that's intended.

[roya0045]

You can try the plugin or remove that version of saga to ensure a supported version is picked, see #33253 and #36800 for some context.

[agiudiceandrea]

@osgeokr if you understand the meaning of the warning message and you really don't like it to be displayed, then you can disable it modifying the following lines of the file SagaAlgorithmProvider.py (in your install_dir/apps/qgis/python/plugins/sagaprovider/ folder)

https://github.com/qgis/QGIS/blob/1601ec46d06e82d953384b541a6004d975cedc57/python/plugins/sagaprovider/SagaAlgorithmProvider.py#L85-L89

    def warningMessage(self):
        #version = SagaUtils.getInstalledVersion(True)
        #if version is not None and version.startswith(BETA_SUPPORT_VERSION):
        #    return self.tr('SAGA version {} is not officially supported - algorithms may encounter issues').format(version)
        return ''

[gioman]

then you can disable it modifying the following lines of the file SagaAlgorithmProvider.py (

@agiudiceandrea we should remove the warning anyway. The main reason it was added it was when osgeo4w and major linux releases shipped SAGA 2.*. Isn't the case anymore.

[nyalldawson]

@gioman except it still isn't officially supported .. all the description files still relate to 2.x only.

[agiudiceandrea]

@nyalldawson, QGIS installed via OSGeo4W v2 uses the SAGA provider description files automatically generated by the installed SAGA-GIS 7.8.2 tool "QGIS Tool Interface Generator" (dev_tool 7) and not the ones for SAGA-GIS 2.x: https://github.com/jef-n/OSGeo4W/blob/426e992b71ae7cc44c427e255b77d15776cc355c/src/qgis/osgeo4w/package.sh#L233-L262

[nyalldawson]

@agiudiceandrea

Osgeo4w is patching this downstream, so should also be patching out the warnings

Upstream (here) only supports 2 as of right now.

[agiudiceandrea]

So, this issue should be better reported in the OSGeo4W tickets system and addressed by the OSGeo4W v2 repository.

[gioman]

Osgeo4w is patching this downstream, so should also be patching out the warnings

@nyalldawson @agiudiceandrea @alexbruy and this is creating some confusion... We are still far away from having SAGA move out of QGIS and live as its own plugin, and I think we should improve the situation and I'm willingly to do something about it. The description files that are taken from the SAGA project are better than the core ones, because they support SAGA 7, but they are not 100% ok (several tools needs to be split because there are parameters that cannot be provided at the same time). Nyall and AlexB plugins have better description files, but I think they also need some correction. For the time being would be ok to take the best of both sides and use them upstream (here) for the time being? I understand is less than ideal, but still better than we have now. We then could remove the warning and have the same description files on all platforms.

[nyalldawson]

Honestly, at this stage I'm completely done with the SAGA provider and trying to manage this situation. @gioman if you feel it's the right decision to update the description files in QGIS master to the 7.x ones then I won't object. :+1:

[ARTCON2020]

Still the same warning appears from SAGA core

Is there any analysis outcome deviation or uncertainties because of this warning message?

[mteora]

Hi there!

I have the same problem with SAGA plugin in both versions, ltr 3.22 and 3.24.

The issue started when I still had 3.16 version. The plugin wasn't running so I had installed SAGA NEXT GEN, which is running pretty well.

Have there any people who have solved the problem?

[agiudiceandrea]

@mteora, what issue do you have exactly? You only don't like the warning message to be displayed? If so, then you can follow the advise in my previous comment https://github.com/qgis/QGIS/issues/46837#issuecomment-1013458152

@mteora please what version of saga did you install? Any from below?

[agiudiceandrea]

@diegoerp91, there is no need to manually install SAGA-GIS from SourceForge. If your SO is Windows and you are installing QGIS using the official OSGeo4W Standalone/Network installers, then SAGA-GIS is already automatically installed and available in QGIS.

[mteora]

@agiudiceandrea My installations are from OSGeo4W. I have uninstalled several times, even deleting registry to do a clean install of the different versions of QGIS in two different computers and I still have the same problem in both of them. Plus the warning displayed, SAGA plugin did not work in any QGIS versions either.

@diegoerp91 I'm not solve the problem with SAGA but there are other complement named SAGA NEXT GEN which have been developed for North Road. This has worked pretty well for me in both of my computers (laptop and pc) and for that plugin I downloaded the last version but I think it could be running with others too.

I provided you some links. https://github.com/north-road/qgis-processing-saga-nextgen https://plugins.qgis.org/plugins/processing_saga_nextgen/ https://youtu.be/VKdaripCups

I hope this will be useful for all of you.

[alexbruy]

SAGA Provider was not maintained and now remowed from QGIS (see #50834). Users are encouraged to use the 3rd-party plugins instead.

[Andares92]

I have a similar problem and I don't know how to solve it: i am doing a watershed flow analysis, i use the tool. analysis of terrain, channels and streamflow order it tells me that the version is not officially supported SAGA V8 QGIS 3.28.10

---

Tengo un problema similar y no se como solucionarlo: estoy haciendo un análisis de flujo de cuencas, utilizo la herramienta análisis de terrero, canales y orden de corrientes me dice que la versión no es oficialmente soportada SAGA V8 Ggis 3.28.10
