I can confirm on Windows with master/3.4, but errors are a slightly different. 3.4 complains about missed gdal_merge.bat, while in master it can not find gdal_merge.py

confimed here the slightly different message.

So this is an osgeo4w packaging issue, right? Not qgis?

probably, but I'm afraid that at this point filing this bug only in the ogseo4w bug tracker will pass unnoticed and we will ship a new release with such important tools broken.

Does gdal_merge.bat
exist in %OSGEO4W_ROOT%\bin
? Should have been created by etc/postinstall/gdal-python.bat
(which runs bin/make-bat-for-py.bat
) after gdal-python
was installed.

Oh, well. Findings so far: 3.4 runs the batch files which only gdal-python
(GDAL Py2 bindings) provides - but it's didn't depend on it, because QGIS normally uses python3 - hence the batch files calls fail. It starts working once that is installed (and a dependency was added).
master was changed to run the scripts directly with python3 (see #20870). That only helps if if the scripts are in the current working directory - but that usually
is %OSGEO4W_ROOT%\bin
, which also happens to be where gdal-python
puts the scripts - intended for py2, but not any different from those for py3. So with gdal-python
scripts installed it should work there too - often.
My expectation was, that python would look in PATH
or PYTHONPATH
for script files - apparently not happening.
