Hello,
i have recently created many bigger scenery chunks with Corine Landcover and
OSM line data. Yesterday I wanted to do the same for all of the UK and
Ireland. Then I encountered some problems:
I encountered "unknown runway surface" errors, caused by some strange
heliport runways (see EGTG). I created a patch to circumvent this for now:
https://gitorious.org/papillon81/terragear-
cs/commit/263a1cdd537bd07e2d5a503b38043f8faee29e38
After that genapts segfaulted during EGKK processing and right until now I
have still not much of a clue what exactly is going on. I thought it was a
problem with compiling TG against SG and not SG-CS (all from GIT). That
showed to be wrong. Next guess was overoptimization (-O2 and -march), yet
unsetting this and recompiling did not solve it either. So I'm still
investigating. A backtrace is attached. If you have any ideas i'd be glad.
Cheers
Chris
