[mkgmap-dev] Trouble with merging IMG files (for Garmin)

Thu Jul 13 20:20:36 BST 2023

Ah sorry, I overlooked the "=". It now creates a gmapsupp.img but it has the same size as the last input-file (in the example below the otm-germany-contours.img file), so the files are not combined.

I then thought that maybe the contour file is not combinable with the other ones, so I tried combining Hungary and Slovenia but then I get again a small 2.5KB file (the last paste block)

The maps are all from garmin.opentopomap.org so I think they should be compatible. I also don't see any errors or warning which could be related to the failed merge, other than that "Could not copy MAKEGMAP.MPS", which I don't know what it is.

Any ideas? ;-/
