[mkgmap-dev] Relations and Multiple Tag Parsing Style Rules

Mon Dec 15 16:28:51 GMT 2008

I have tried to use it, but it doesn't seem to work (mkgmap trunk svn 
version 823). I assume I'm using somehow wrong syntax and need more 
explanation.

a)
concerning relations I simply wrote this line to relations file to line 7:
type=route route=bus { apply { set route=bus; add rn='${route_no}' ; }}

this is what I got:
D:\Garmin\mkgmap_680>java -jar -Xmx1256M 
d:\garmin\mkgmap_svn\dist\mkgmap.jar --description=Osm_Mtb_Austria3 
--family-id=4013 --style-file=mtbx --product-id=1 
--levels=0:24,1:22,2:20,3:18,4:16,5:14,6:12,7:10 --area-name=austria3 
--mapname=63240030 austria.osm
Error in style: Error: (relations:7): Invalid rule file (expr =)
Could not open style null

b)
Also multiple Tag parsing does not seem to work for me.

I added the following two lines to the beginning of the "lines" file in 
the style-file
highway=path & mtb=yes [0x140 resolution 16]
highway=footway & mtb=yes [0x141 resolution 16]

And created a new file called "overlays" with the following two lines:
0x140: 0x11, 0x0e
0x141: 0x2a, 0x0e

Error in style: Error: (overlays:2): List of numbers expected
Could not open style null

D:\Garmin\mkgmap_680>move 63240030.img d:\garmin\osm_austria
The system cannot find the file specified.

If in overlays there are the following lines

Line1:0x140: 0x11, 0x0e
Line2:0x141: 0x2a, 0x0e
Line3:

with Line 3 being empty, then the following error is produced:
