Hi
Now I started using the index on the main layer and it works great - as long as I don't try to combine all layers to a single gmapsupp.img, which I always do by calling mkgmap with all sublayer gmapsupps as input files:
java -jar mkgmap/mkgmap.jar --gmapsupp --nsis --description="OSM-Topo-DE" --overview-mapname=topo-gesamt deutschland/gelaende/gmapsupp.img deutschland/landuse/gmapsupp.img deutschland/topo/gmapsupp.img deutschland/maxspeed/gmapsupp.img deutschland/isohypsen/gmapsupp.img deutschland/isohypsen2/gmapsupp.img deutschland/wanderwege/gmapsupp.img deutschland/lit/gmapsupp.img
When doing so now, the resulting gmapsupp.img is lacking the complete main layer, but no error message is given.
Is that something that worked in earlier versions? There is nothing that I can think of that might have altered that.
Yes, this worked, but without the --index option - I only began using it recently, when the index branch was merged back to trunk. (it still works without --index in recent versions)
When I add --index to the command line, I get the following error message immediadely:
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: -1 at java.util.ArrayList.get(ArrayList.java:324) at uk.me.parabola.imgfmt.app.mdr.Mdr29.preWriteImpl(Mdr29.java:62)
OK, it is a bug that an error is thrown like that, but in any case the indexing code will not work if given gmapsupp files rather than individual tiles. It would be possible to make it work, but it is not a simple change.
OK, I now also tried to modify the command line, feeding mkgmap individual tiles, plus the overview-map.img of each layer, too. Now all layers are present in the gmapsupp.img, but I lost all layer names, .TYP files and the search index. Or should I include the *.mdx file? I think I'll try that tomorrow.
