[mkgmap-dev] Error writing overviewmap - continue at failure

Sat Feb 27 14:48:41 GMT 2021

Hi,

I think the below error message is for writing the overview map.
Of which I would not be surprised, it was a test on splitting and building a full-planet.osm map. So... no worries.

But now I'm wondering if there is a way in which I could continue testing with the already generated 4.426 img-files and 4.426 ovm_work files to obtain a .tdb file, mdx files, nsis installer etc.
It took 21 hours for mkgmap sofar, so it would be nice if that time spent was not useless.
I used splitter with maxnodes 1.700.000 which took another 9 hours and did not give errors when building a single .img file

I would like to simplify the style-file run mkgmap again on the previous output and try the create an overview map only (So without building all the img files again) and this way iterate until I found the breakpoint.

  1.  Would that make sense?
  2.  Could I enable some more error/verbose logging to obtain info about sizes/counts or whatever indicators that would help to see if my changes help in my search to a smaller overviewmap.
  3.  Would It make sense to not generate a MapFailedException but a warning only? So mkgmap would continue finishing the last millimeters to the finish (off course without a working overviewmap)

Kind regards
Joris

SEVERE (MapFailedException): (thrown in BufferedImgFileWriter.ensureSize()) There is not enough room in a single garmin map for all the input data. The .osm file should be split into smaller pieces first.
