[mkgmap-dev] SEVERE (PolishMapDataSource): error decoding label

Thu Dec 24 18:51:59 GMT 2009

Hi,

I'm trying to generate Garmin maps files from Polish maps generated by 
GroundTruth. I get the following exception (using the latest version of 
mkgmap):

SEVERE (PolishMapDataSource): error decoding label

The same MP file works in cgpsmapper without problems. It's quite large 
(47 MB) so I'm not able to detect which label is the culprit for the 
exception.

Is there any way to see which line of the MP file causes the problem?

Thanks,
Igor
