[mkgmap-dev] Routing is not workng

Hello, Route calculation in MacOS Basecamp latest version is not working with the map I generate. I use to build my map since many years and it seems that my problem appears last year around May. As I customize the style and I manage my maps with some layers, I checked it with the default style, the latest version of mkgmap and Ireland OSM data deom Geofabrik without my additionnal layers. The result is the same : route calculation is not working in the latest Basecamp version for MacOS. Could anyone give me a clew to solve this problem ? David Compilation options include route, bound, drive-on-left, option to add some POI for access to motorways... and I produce a custom TYP built with my own software.
