Lots of modules not working in MacOS

[Spartacus1]

QGIS 3.8.3 is not able to do several simple operations. A simple Layer Clip returns the following error:

GDAL command:
gdalwarp -of GTiff -cutline /Users/xxxx/Desktop/MapasViana/dummyextent.shp -cl dummyextent -crop_to_cutline "/Users/xxxx/Desktop/Desktop-A/Trabalho Geral/Viana_geossitios/layers/AltimetriaViana_alargada.tif" /Users/xxxx/Desktop/testelixo.tif

You can check the 'Log Messages Panel' in QGIS main window to find more information about the execution of the algorithm.

@Spartacus1 , use native QGIS algorithm, not 3rd party gdal ones. It'll fix your problem. Sorry, I should have read your issue more closely, you are trying to clip a raster, which can only be done via gdal algorithm.

Which installer did you use?

Hi nirvn. Thank you so much for reply. Used the one available for download from qgis.org
I've done this clip operation countless times without any issue. Since version 3.8, this error started to appear.
Several modules from the raster menu or from processing are failling with similar issues.

Even an hillshade will end up with the same issue:

Since version 3.8

can you confirm that if you rolls back to 3.4 it works? Can you try also on another machine (just to exclude possible local problems)?

[Spartacus1]

Thanks Giovanni

The modules fail both in 3.8.3 and in 3.4. Everything is working in William's (KingKaos) compilation.
They failed under Mojave. In another machine, with HighSierra, they also fail.

It's related for sure with the "libiconv.2.dylib" and probably with others.

I did the following experience:

Since the error by doing a Hillshade returns

I went to /usr/lib/ copied the "libiconv.2.dylib" from there (which is a version from last May) and replaced for the one in /Applications/QGIS3.8.app/Contents/MacOS/lib/

By doing this, the Hillshade module works.

Cheers

PS: this error seems to be similar or even the same as this one #31576

Maybe they can be merged.

[nirvn]

I think this issue should a/ be merged with #31576 , and b/ closed in favor of opening an issue in the appropriate QGIS Mac Packager repository (https://github.com/qgis/QGIS-Mac-Packager/issues)

[gioman]

I agree is duplicate of #31576
