[mkgmap-dev] Compilation fails building France map

Sun May 24 11:16:34 BST 2020

Hi!

I made a few tests according to Gerd and Joris instructions.

My style is not so heavy for overview map and all modifications I tried 
to make it lighter failed.
So I replaced my style with default style and mapnik typ within my 
scripts… that failed !

The fact is I merge a national addresses db (BANO -> 
http://bano.openstreetmap.fr/data) with the Geofabrik pbf before running 
splitter.
If I don't make this merging, compilation run fine.

So it appears that it's not an “esthetic” map particularity but address 
data which produce issues, if I got it right…
And of course I don't know why 😂

Thanks again.

Regards!

Steph
