[mkgmap-dev] Wrong turn restriction warnings

Sun Feb 23 07:06:38 GMT 2014

Hi Carlos,

thanks for reporting this. I fixed a bug in splitter with r316, see 
http://www.mkgmap.org.uk/websvn/listing.php?repname=splitter

You might still see warnings from mkgmap for lacking ways in restriction
relations
if you style doesn't assign a routable type for the to-way or from-way.
See point 4 in this post:
