mkgmap - ClassNotFoundException: Long2ObjectOpenHashMap

Hi,

I'm just figuring out how to create garmin maps from the wiki docs. I exported a small osm file using JOSM and then attempted to run mkgmap as suggested below and got the listed exception. I tried adding and removing several options even down to just gmapsupp and the file. In all cases I got the exception listed.

I had to install java to do this so have the latest version (java version "1.8.0_25"). I don't have to install java 1.7 I hope...

Has anybody seen this error or can see an error with the command? I cannot seem to get around this. I tried running versions back to 3354 of mkgmap and get the same result.

Many thanks for any help.
Blair

Re: mkgmap - ClassNotFoundException: Long2ObjectOpenHashMap

The fastutil-6.5.15-mkg.1b.jar is missing in your classpath.
The file mkgmap-3392.jar is not in the mkgmap download so it looks like that you compile mkgmap yourself? In such a case please ensure that the jar files osmpbf-1.3.3.jar, protobuf-java-2.5.0.jar and fastutil-6.5.15-mkg.1b.jar are in your classpath.

Re: mkgmap - ClassNotFoundException: Long2ObjectOpenHashMap

WanMil,

Thanks for your reply. The mkgmap-3392.jar was just renamed from that which came with the download. When I tried the older version I needed to distinguish the two.

I didn't explicitly set the classpath, I just copied the jar file to the directory with the osm and ran it from there which looks like where the problem was. I looked into the lib directory and saw the jar files you mentioned so I just copied lib to the same directory with the .osm and mkgmap.jar files and it worked.

Thanks again for your reply,
Blair
