[Qgis-user] Problem with the raster combine tool (in spanish combinar) (ruben dp)

[Mike Flannigan]

Try installing GDAL
https://gdal.org/
and see if gdal_merge.py gets installed in /bin/sh.

This isn't likely to fix your problem, but it won't
hurt either.  If you read the GDAL documentation
you might find that you can do the combine in GDAL.
