[mkgmap-dev] Increase MAXHINCR or MAX_HEAP_SECTS

Hi! compiling http://downloads.cloudmade.com/europe/austria/austria.osm.bz2 failed: 'java -Xmx3000M -jar /usr/share/mkgmap/mkgmap.jar --route austria.osm' failed with Too many heap sections: Increase MAXHINCR or MAX_HEAP_SECTS. How can I increase that? Will it help? debians dpkg says its version 0.0.0+svn1067-1. I haven't tried the current version because that hasn't finished a smaller map after 15 mins while debians mkgmap finished in seconds. Bernhard
