[mkgmap-dev] Error in Africa?

Fri Jul 31 19:26:01 BST 2020

Hi Ticker, hi Valentin

my understanding is that the error message from MapSplitter was a false positive because mkgmap reports 0
MapFailedExceptions.

The crash with IndexOutOfBoundsException occurs in the final combiner phase for the gmapsupp. It might be caused by an I/O error or a corrupted *.img file.

@Valentin: If you didn't already try that I suggest to clear the directory and restart the compilation. If that produces the same IndexOutOfBoundsException  please try again without the file 63240201.osm.pbf. Only if that works fine we can be sure that 63240201.osm.pbf is causing the crash.

ciao,
Gerd

Hi Valentin & Gerd

@Gerd, have you started looking at this?

The initial error is related to the splitting of the tile into
subdivisions and is VERY dependent on the size and layout of all map
elements in the tile, which will depend on the style and many options
as well as the actual OSM input.

If not using the default style, can you zip up and post what you are
using, also mkgmap command line and options.

The exception happens later but is probably a consequence of the split
failure.
