[Qgis-user] QGIS 6.3 for macOS 10.14.5 : HELP

[Nuno Manuel de Figueiredo de Santos Loureiro]

Hi Ramon,

Many thanks.
I followed your recommendations.
However a few issues remain.
William wrotes:

/Library/Frameworks/Python.framework/Versions/3.6/bin:/Library/Frameworks/GDAL.framework/Versions/2.3/Programs:

in the step by step
But he also says that GDAL is 2.4 and not 2.3.

I checked in my computar and I have GDAL 1.11, 2.1, GDAL 2.2 and GDAL 2.4.
I believe that GDAL 1.11 and 2.1 is needed for QGIS 2.18.23, that GDAL 2.2 is not needed and that GDAL 2.4 is needed for QGIS 3.6.2.
Is this true?

After, I changed the above line to

/Library/Frameworks/Python.framework/Versions/3.6/bin:/Library/Frameworks/GDAL.framework/Versions/2.4/Programs:

(only 2.3 to 2.4)

Finally the Merge a few rasters works well ;-)

But the following step, the Clip a raster using a mask layer is not working.
Instead I received the following message:

ERROR 1: Cutline polygon is invalid.


Note that the same task (Clip a raster using a mask layer) in QGIS 2.18.23 (using the same input layers) runs without any kind of troubles.


Ramon, have you any additional suggestions???


many thanks for your attention,


Nuno

Hi Nuno,

You need to set some environmental variables, so that the GDAL binaries can be found.
William provides a nice step by step in file Read Me.txt

If you’ve already deleted the dmg I’ll paste it into a reply, but you should read Read Me.txt because it contains other useful bits of information besides the answer to your question.

Regards,
Ramon.

Hi all,

I'm a very regular (happy) user of QGIS 2.18.23.
Recently I installed QGIS 6.3.2 on my Mac with macOS 10.14.5.
Several tasks are running very well but when I tried to merge a few rasters I was not able to do that and I received the following message:

GDAL command output:
/bin/sh: gdal_merge.py: command not found

Also, when I tried to clip a raster using a mask layer I was not able to do that and I received the following message:

GDAL command output:
/bin/sh: gdalwarp: command not found

What is missing or wrong?
Can somebody help me with some tips to fix this issue?

Many thanks in advance,

Nuno
