[mkgmap-dev] Problem with --index and 812KB _mdr.img files & "warning using default sort"From Felix Hartman extremecarver at gmail.com on Wed Mar 16 01:14:17 GMT 2011
Okay, well found out that the broken size is always the same. So for now on I just look whether *_mdr.img is smaller than 828KB (that's the smallest working I could produce for tiny map) and if found, I know the compile failed. The problematic thing on this error is, that usually if _mdr.img cannot be created because of memory shortage, also the overview map is not created. However you can run into the problem that the overview map is created but the index cannot be written out due to low memory and hence a crash that I did not expect. As long as the broken *_mdr.img does not increase in size, I can work without any patch to this (ideally though mkgmap should delete the tdb, the overview map and the _mdr.img in case of low memory so it's harder to run into such problems (the problem is here, that while you can open the map in mapsource, trying to send the map to the gps will crash Mapsource severly, needing to close it via task-manager) 2011/3/16 Felix Hartmann <extremecarver at gmail.com>: > 1.
