Hi my style include a lot of rules like this: highway=footway [0x1200d resolution 23-23 continue] highway=footway [0x1100d resolution 24 continue] highway=footway & (bicycle=designated | bicycle=permissive | bicycle=official | bicycle=yes) [0x0a resolution 24 road_class=0 road_speed=1] highway=footway [0x0d resolution 24 road_class=0 road_speed=0] IMHO mkgmap count four lines, is that correct? now it is difficult to find the error, if the files includes up to 700 lines, i think, there are some larger styles around the world mkgmap tells: Error in style: Error: (lines:393): Stack size is 0 but the line with the error is line 485 in the style file my error was to use '[' instead '(' ;-) Bernd
