Hi Gerd,
the FileExistsException problems (or their reporting) may have been
introduced later.

Hi all,
OK, seems I was wrong. Felix Herwegh contacted me in a private mail and he has
an example where mkgmap is able to merge two gmapsupp.img files. With his
examples mkgmap just writes some warnings about duplicated files:

So, yes, there is code to read the content of a gmapsupp and copy it to the
output gmapsupp, but this code only seems to work well when the last file in
the input gmapsupp is the special file MAKEMAP.MPS
I am not sure if this is wanted or just a flaw in the implementation. I am also
not sure how well the result really works, and there are also other problems,
e.g. the option --index doesn't work.
The code was added in 2009 with
r1443:https://www.mkgmap.org.uk/websvn/revision.php?repname=mkgmap=1443
Attached quick hack shows that it is very easy to change the code in mkgmap to
be more tolerant regarding the oder of the files within the gmapsupp, but I
have no idea about the restrictions that apply and how to handle the case that
the input gmapsupp files contain equally named TYP files with different content
or indexes etc.
So, not sure what to do here. Looks like a can of worms...

What you try is not implement.
You simply have to understand that mkgmap cannot read data in gmapsupp format.
All the mentioned files are in gmapsupp format.
So, either use a different tool or maybe split the gmapsupp files first, e.g.
with gmaptool.

Hi,
so I tried combining [opentopomap] Hungary and Slovenia but then I get again a
small 2.5KB file
Same here. My test were on simple maps without routing and DEM only; maybe its
that. Sorry.
