I downloaded the latest gmapi-builder and tried the following: ===== python gmapi-builder -v -t for_mapsource/40000001.tdb -b for_mapsource/40000001.img for_mapsource/40000001.img for_mapsource/40000001_mdr.img for_mapsource/63240001.img -s for_mapsource/MINIMAL.TYP Unknown Block: 54, length: 20, '\x00\x00\x17\x00\x00\x00\x00\x00\x00\xe6\x00\x00\xce\x00\x00\x00\x00D\x00\x00' TDB Version: 4.07 Product ID: 1 Family ID: 639 Map Series: OSM_PHIL Map Family: OSM_PHIL Product Version: 1.00 Copyright: OSM Street map Copyright: http://www.openstreetmap.org/ Copyright: Map data licenced under Creative Commons Attribution ShareAlike 2.0 Copyright: http://creativecommons.org/licenses/by-sa/2.0/ Copyright: Map created with mkgmap-r1867 Copyright: Program released under the GPL Trademark: Test preview map Overview map: Map Number: 63240000 Parent Map: 0 Latitude North: 21.5771 Longitude East: 127.7930 Latitude South: 4.5264 Longitude West: 115.6201 Description: Overview Map Missing part: 0 of S?.ϻ in IMG-file. ======= The same data was used for a mapsource installer compiler and there are no problems with mapsource.
