Hi Richard,
Hi,
I have recently downloaded some mkgmap generated maps that produce this error when displayed in navit: :garmin_obj.c:1279:1|:Error more than 255 polygons/lines in a subdiv are not supported
This does not look like an mkgmap problem to me. Reading the error message I assume that navit does not support subdivisions containing more than 255 polygons + lines. But as far as I know there is no such a limit for garmin devices.
I have taken a look into the source code. There is a limit for 255 lines with garmin id < 0x010000 per subdivision but no single limit for polygons. Lines, points and shapes with garmin id > 0x010000 have their own limits based on the size they need. But I wonder why there is no single limit for polygons. Only the overall size of points+lines+polygons is limited to 65528 bytes. Maybe this is wrong?
It seems there were some patches for this around, did they get integrated? Do they require some special option?
There is at least one known bug regarding the creation of subdivisions. I am working on it and will post the patch when it is ready to commit.
There is a first version of the patch (see http://www.mkgmap.org.uk/pipermail/mkgmap-dev/2011q2/011818.html) but some things are not fixed in it.
Tried to reporduce the issue it with mkgmap-r2009 and attached test data, I get neither the above error but the object (the Altenburg in Bamberg) isn't displayed either.
Can you please how you created your map? 1. Where did you get your data from? 2. Did you use splitter and which splitter settings do you use? 3. Please send your complete mkgmap parameters. Otherwise it is not easy to reproduce the problem.
Thanks! WanMil
