Hi Ticker
Thanks for the suggestions. I use the same $Vars for many other maps and
this is the only one that is wrong, but I'll investigate it. Regarding
log, as mkgmap runs without any warning I'm afraid it won't contain any
useful information, but I'll have a look at it.

Hi Carlos
The first 0x1b0000 bytes (1.68MiB) of your gmapsupp.img are zero! It should
start with something like:

You should check the expansion of your command, esp. all the $Vars and * to see
that the parameters are exactly as you expect and stray files are not getting
into the build.
Are you generating a mkgmap.log.#n? If not suggest you investigate this
(-Dlog.config=mkgmap_log.props option)

Hi all
I'm having problems with a gmapsupp.img file created with mkgmap. It's
not recognized by GPS and GMapTool reports header is wrong. I have
recreated it from scratch and it continues failing. I have not changed
my tool chain for a long time, so I don't know what may be causing the
problem.
Map is created with the following command:
java -Xmx27G -ea -jar mkgmap.jar --index --gmapsupp
--family-name="OpenStreetMap $MAPA" --family-id=${GRUPO}1${FID}
--country-name=$PAIS --country-abbr=${ABR} --area-name="$MAPA"
--product-version=$VERSION --series-name="OSM-$MAPA"
--road-name-config=roadNameConfig_suffixes.txt --route
tmp/${GRUPO}1${FID}*.img tmp/${ABR}${GRUPO}1${FID}.txt
--description="OpenStreetMap $MAPA" --no-tdbfile
Another gmapsupp created from the same *.o5m input files but with a
different style is correct, but many other maps created with the same
style are also correct, so I don't think style may be the origin of the
problem.
Problem file can be downloaded from
