[mkgmap-dev] IndexOutOfBoundsException

Tue Aug 8 12:39:38 BST 2023

Hi all,

i am trying to import an osm europe map into Garmins Basecamp.

I downloaded the europe-latest.osm.pbf from Geofabrik. Then i used the
splitter with the following command.

``` java -Xmx20g -jar splitter-r653/splitter.jar --output=o5m
--max-areas=4096 europe-latest.osm.pbf ```

It finished after writing a series of 2105 .o5m files. By creating the
gmapi directory with the following command, i got an Index Out of Bounds
Exception.

``` java -Xmx20g -jar mkgmap-r4910/mkgmap.jar --index --improve-overview
--gmapi -c template.args ```

Here the Stack trace:

I assume the problem occures because of the huge template.args file
(~6000 lines), but i'm not that much into java to deterrmine the exact
cause. Any ideas?

Cheers,

Thomas
