[mkgmap-dev] NullPointerExceptio

Fri Dec 22 20:30:39 GMT 2017

Hi,

false alarm.
Not sure if this is an error in mkgmap:
When I create a map with options
--output-dir=e:/ld  --x-dem-dists="5520, 16560, 44176, 88368"  --x-dem=f:\osm\phyghtmap\hgt\SRTM1,f:\srtm3    --show-profiles=1 --gmapi  --max-jobs --route --index -c e:\osm_out_work\nepal\20171219_165254\template2.args
and copy the gmap folder I can create a gmapsupp in MapSource.
If I remove the option --route and do the same this no longer works. When I also remove the two dem options it works again.

@Steve: I think the problem is in DetailMapBlock.writeBody() which seems to expect that DEM is only written if also NET and NOD exist?

Gerd

Hi Andreas,

yep, please use r4017.
I've just noticed that with the latest versions MapSource doesn't create a gmapsupp for files with DEM.
I think that worked after I added the --x-dem-dists option. No idea what is wrong now.

Hi Gerd,

probably your fix for „POI without a name in overview map“ made it not into the new branch?

Andreas

Hi Andreas,

thanks, I've fixed this in r4000. I wonder why this did not show up before. Seems that nobody else has POI without a name in his overview map?

Gerd

Hi Gerd,

http://files.mkgmap.org.uk/detail/369

includes a zip-file including

* Mkgmap-call
* Style and typ – file
* 2 out of 37 pbf-files covering Austria

If I build a map only with *001.osm.pbf everything works fine (also with some others). If I do so with *0036.osm.pbf (also with some others), it doesn´t.

Regards

Andreas

Hi Andreas,

the problem occurs while reading the ovm*.img files for the overview map. It seems that mkgmap reads a POI without a label, thus the NullPointerException.
The code contains no check for this, so I guess it normally never happens, so maybe it is an I/O problem. If you can reproduce the problem and there is no simple
explanation like a full disk please post the style and describe how you create the pbf files so that I can reproduce the problem.

ciao,
Gerd

I built many maps so far – never got this error. What do I have to obtain for further analysis?
