I use to add readily compiled contourline files to my maps. They are in --latin1 and don't have any information that would be needed to appear in the search index. I will then always get warnings like the following - even though the maps seem to work fine in Mapsource, Basecamp and on my GPS.. /WARNING: input file 73630000.img has different code page 1252// //WARNING: input file 73630000.img has different charset type 10// //WARNING: input files have different code pages// / (e.g. ftp://ftp5.gwdg.de/pub/misc/openstreetmap/openmtbmap/odbl/mtbmonaco.exe - just unzip the .exe - it's lzma packed. there is one "map data" file 63630000.img - one contourlines file 73730000.img - and then a "mapsetx" set of files which excludes the 73730000.img, one "mapsetc" set of files which includes the 7373000.img (well and then one mapsetz which is for installing the contourlines as separate contourlines only map)) Sometimes on bigger maps - mkgmap even crashes while running due to the codepage/charset option - e.g. if I create a map of Europe... Dunno really why this crashes.. start /low /b /wait java -jar -Xms6000M -Xmx10300M c:\openmtbmap\mkgmap.jar %max-jobs% %generate-sea% %precomp-seaxx% %style-file% --nsis %indx% %levels% --adjust-turn-headings --add-pois-to-areas --reduce-point-density=3.4 --reduce-point-density-polygon=6 --housenumbers --link-pois-to-ways --ignore-turn-restrictions --polygon-size-limits="24:16, 23:14, 22:12, 21:11, 20:10, 19:9, 18:8, 17:7, 16:6, 15:5, 14:4, 13:3, 12:2, 11:0, 10:0" --description=openmtbmap_%abr% %showprofile% %locationxx% --route --country-abbr=%abr% --country-name=%country% --mapname=%FID%0000 --family-id=%FID% --product-id=1 --series-name=openmtbmap_%country%_%date% --family-name=mtbmap_%abr%_%date% --tdbfile --overview-mapname=mapsetx --keep-going --area-name="%country%_%date%_openmtbmap.org" -c c:\openmtbmap\maps\template.%countryx% 7*.img>NUL Where could I switch off the warning (in code) -- keep on biking and discovering new trails Felix openmtbmap.org & www.velomap.org
