[mkgmap-dev] Creating gmapsupp.img fails with: Cannot invoke "String.endsWith(String)" because the return value of "uk.me.parabola.mkgmap.main.Main$FilenameTask.getFilename()" is null

Hi Felix,

I still don't understand the concept of resplitting. Is it meant to fix problems until you find time to look at the server or should it work in long terms? If you resplit more and more tiles I don't see how it will improve the map or the resource usage.

yeah that makes resplits easier. You do not need to go into the template.args file anymore and comment out missing tiles. So it's enough to just delete those input tiles that were too big.

Hi Felix,

I've added a null check with r4807.

Okay - this error can be solved by removing the "Input that do not exist from the template.args input file. - e.g. if 85610002.o5m does not exist need to remove the line
input-file: 85610002.o5m
from the template.args file.

Partly related to the other problem - if I run mkgmap on the splitted files - I get this error. All .img files seem to be fine, but the gmpsupp.img is created with 0 bit size.

This is not happening every time I resplit tiles. In this case two tiles were joined by osmconvert - and splitter splits it into three tiles. Then all .img files are created correctly, but the mapset.tdb / mapset.img files are not created - and the gmapsupp.img has 0 size, the gmapi files is also not created.

I guess this happens because splitter somehow made a melange of the two input files into three?

I really think the only thing missing in resplitting the too big tiles from mkgmap is an appropriate keep-complete mode - that keeps each input tile complete - but does not join input tiles. So osmconvert merging the input tiles is a bad idea even though it mostly works.
