While looking through the source code I observed that the drive-on-left/right flag is set statically in the NODHEader class. That means that a threads of one tile modifies this flag of all other tiles. So when compiling a european map with GB included, it's a kind of lottery if the GB areas really have this flag set.
Do I miss something? WanMil _______________________________________________ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
