<p><tt>Hello, all!</tt></p>
<p><tt>Does this tile happen to contain the Port Said area near
Cairo, Egypt? If so, you may be facing the same problem that I
encountered in splitter. Splitter only limits the number of
nodes in a tile. It ought to limit the number of ways as well.
The Port Said area has an immense number of single city block
length streets not joined into longer streets. I have built maps
for the entire planet. That is the only place that I found that
had that problem. The solution was to build Africa using a max
nodes value of about 600 thousand nodes as you did, which
brought the number of ways down sufficiently to avoid the
problem in mkgmap. If splitter had an option to limit the number
of nodes, then splitter would have divided the Port Said tile
sufficiently that just those tiles would have had to be made
small.<br>

hi Gerd,<br>
thanks for your attention.<br>
<br>
I continue to do my experiments. I tried to compile the map from
this one 63240201.osm.pbf with and without the --gmapsupp option
(of course to an empty output folder). I get the same result on
my two FreeBSD servers and my Windows home computer. I am
getting this error on all my systems.<br>

<span style=" font-family:'consolas'; font-size: 9pt;">Earlier I
found a way to fix this error when I use the --max-nodes=600000
value. But this will produce an extremely large number of tiles!
I really don't like this result. The same number of tiles is
produced by the splitter when I making a map of the whole of
Europe without the --max-nodes option. The compilation of the
map of Europe is stable and looks very good without errors. But
the original europe-latest.o5m is four times larger than
africa-latest.o5m!<br>
I see this is an old and complex spiltter problem. I'm just
trying to find out how OSM data is causing this error. It is
still unpredictable for me.<br>

Ticker, hi Valentin<br>
<br>
my understanding is that the error message from
MapSplitter was a false positive because mkgmap reports
0<br>
MapFailedExceptions.<br>
<br>
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.<br>
<br>
@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.<br>
<br>
ciao,<br>
Gerd<br>

Betreff: Re: [mkgmap-dev] Error in Africa?<br>
<br>
Hi Valentin & Gerd<br>
<br>
@Gerd, have you started looking at this?<br>
<br>
The initial error is related to the splitting of the
tile into<br>
subdivisions and is VERY dependent on the size and
layout of all map<br>
elements in the tile, which will depend on the style and
many options<br>
as well as the actual OSM input.<br>
<br>
If not using the default style, can you zip up and post
what you are<br>
using, also mkgmap command line and options.<br>
<br>
The exception happens later but is probably a
consequence of the split<br>
failure.<br>
<br>
