Hello, Always testing, to find out what I'm doing wrong. If I run mkgmap that way : OPT_GMAPSUPP=" \ -Xmx896M \ -jar $FILEDIR/mkgmap.jar \ --country-name=$COUNTRY_NAME \ --country-abbr=$COUNTRY_ABBR \ --family-id=148 \ --gmapsupp \ --ignore-maxspeeds \ --ignore-turn-restrictions \ --latin1 \ --location-autofill=1 \ --lower-case \ --preserve-element-order \ --product-id=$INDEX_CARTE \ --remove-short-arcs \ --road-name-pois \ --route \ --style-file=$FILEDIR/styles/arvernes \ --tdbfile \ --transparent \ -c $CARTESDIR/template.args \ " java $OPT_GMAPSUPP --description="$DESCRIPTION" --family-name="$FAMILYNAME" --series-name="$SERIESNAME" Or that way : OPT_GMAPSUPP=" \ -Xmx896M \ -jar $FILEDIR/mkgmap.jar \ --country-name=$COUNTRY_NAME \ --country-abbr=$COUNTRY_ABBR \ --family-id=148 \ --ignore-maxspeeds \ --ignore-turn-restrictions \ --latin1 \ --location-autofill=1 \ --lower-case \ --mapname=09050305 \ --preserve-element-order \ --product-id=$INDEX_CARTE \ --remove-short-arcs \ --road-name-pois \ --route \ --style-file=$FILEDIR/styles/arvernes \ --tdbfile \ --transparent \ -c $CARTESDIR/template.args \ " java $OPT_GMAPSUPP --description="$DESCRIPTION" --family-name="$FAMILYNAME" --series-name="$SERIESNAME" The map created is always named : 63240500 For the first run, i understand, but for the second, I thought the map would have been named 09050305.img Between the two runs, I removed the option --gmapsupp and replaced it with --mapname=09050305 The template.args file : mapname: 63240500 description: OSM Map input-file: 63240500.osm.gz So I suppose that once the mapname in the template.args file is given, I can't change it with a parameter on the mkgmap command line, as long as I use the "-c template.args" parameter ??
