[mkgmap-dev] Compile error

Mon May 2 22:13:08 BST 2022

I don't create an overview map. No tiles show up with zero size nor
are any of the 56 tiles larger than about 159,000 nodes. Carlos has
offered a patch to indicate the problem tile but I'm on a Windows 10
system and am not willing to set up a Linux environment just to patch
my mkgmap program.

Is there a debugging tool or method that you can suggest?

The descriptive text in the Options file for directives about processing lines and polygons doesn't make clear how to reduce the amount of information they handle— can you offer any suggestions?

There were more tiles generated by splitter but the same error resulted.
