Hi Andrzej, I am a bit confused. If I got that right the check was introduced together with the levels option with r692 in the year 2008 and seems unchanged since then. http://www.mkgmap.org.uk/websvn/diff.php?repname=mkgmap&path=%2Fbranches%2Fs... On the other hand I see no problem with your patch, though I would use slightly different code, see my version.

I guess this is the latest official release. Now with some old maps I get a new error: Error in style: Error: Level number too large, max=0 I guess this is a conflict between arguments: levels=0:24 and style with declarations like: .... [... level 3] In my opinion, this should be no error, as it wasn't in older versions of mkgmap. It is harmless and quite useful, that style defines higher levels then a particular map compiled with the style. I have attached a patch, but I'm not sure what I'm really changing. Please look at it. -- Best regards, Andrzej
