java.lang.IllegalArgumentException and max-nodes size --- currently impossible for me to create Asia map without a) breaking or b) missing tiles
It is not really nice currently to try to compile Asia from Geofabrik. If I set a high max-nodes value, then it goes through (but about 30 tiles missing), if on the other hand I choose a lower max-nodes value, then the following bug appears. Splitter integration into mkgmap would really be helpful...

Splitter could be integrated into Mkgmap, but it has proven not too difficult to script a subsplit if an Mkgmap render attempt failed. The scripts is described in normal language below, implementing it in Perl, Python, bash or even PHP (as I have) is easy. It might keep Mkgmap slightly ;-) simpler to maintain without splitter incorporated. In my script: When rendering an osm.gz file I check the return value of Mkgmap, the existence of a resulting .img file and that the .img file is larger then 0 bytes. If any of these checks fail then splitter is invoked using a lower node count (e.g. 100k nodes less) until the subsplit results in two or more osm.gz files. These files are then rendered again and for each the process described above is performed again. The only challenge I encountered using this process is keeping tabs on the tile numbers and providing the correct tile number as commandline parameters to Mkgmap and Splitter. I'll post the code of my scripts if there is a need for it. On 25-05-12 17:04, Felix Hartmann wrote:

Hi
Exception in thread "main" java.lang.IllegalArgumentException at java.nio.Buffer.position(Unknown Source) at uk.me.parabola.imgfmt.Utils.bytesToString(Utils.java:80) at uk.me.parabola.imgfmt.sys.ImgHeader.setHeader(ImgHeader.java:255)
This happens when one of the input files is zero length (or otherwise corrupt). Attached is a patch which detects short files and gives a message including the file name. ..Steve
