Hi Melchior,
Many thanks for your reply.
xmllint reports no errors.
Hmm. strace is an excellent idea. Its output shows large numbers of
interesting files being opened. I didn't realise that strace was such a
useful tool for examining the progress of a running program.
The output from strace includes the following lines:
[pid 20172] open("/usr/share/games/FlightGear/Traffic/fgtraffic.xml",
O_RDONLY|O_LARGEFILE) = 12
[pid 20172] open("/usr/share/games/FlightGear/Traffic//QAN/737/737.xml",
O_RDONLY|O_LARGEFILE) = 13
[pid 20172]
open("/usr/share/games/FlightGear/Traffic//QAN/737/QAN01.xml",
O_RDONLY|O_LARGEFILE) = 14
...which all look okay to me.
strace does /not/ include a reference to a "parking.xml" file, which is
significant, which means that FG is not attempting to open the file
/usr/share/games/FlightGear/Airports/AI/YMML/parking.xml
BTW, it also includes the line
[pid 20172]
open("/usr/share/games/FlightGear/Traffic//general/KSFO/c172.xml",
O_RDONLY|O_LARGEFILE) = 13
...which does strike me as odd, when I'm flying around southern
Australia. Why would FlightGear be opening a "KSFO" file?
I apologise for asking some off-topic questions, but I'm trying hard to
get my head around this FlightGear thing.
Regards,
Greg Hawkes

When I run fgfs, it displays the following rather unhelpful error message:
Could not find YMML
Durk is your man, but I'll try to help anyway. First check if your
XML files are really spec compliant:
$ xmllint /usr/share/games/FlightGear/Traffic/QAN/737/QAN01.xml
FlightGear does not always tell you if there are problems. (Yes,
that's a usability bug).
If that didn't show anything suspicious, try this:
$ strace -fF -eopen fgfs --airport=ymml 2>&1|tee /tmp/log
Then check in /tmp/log for the place where your files should get
loaded, and apparently aren't. This could show you wrong paths.
