I edited line 507 of fg_init.cxx as log level ALERT works at this point
void fgFindAircraftInDir(const SGPath& dirPath, T* obj, bool
(T::*pred)(const SGPath& p))
{
if (!dirPath.exists()) {
SG_LOG(SG_GENERAL, SG_ALERT, "fgFindAircraftInDir: no such path:" <<
dirPath.str());
return;
}
and the result was:
fgFindAircraftInDir: no such path:C:/Flightgear/fgdata/Aircraft
Single stepping the debugger showed that fopen in simgear SGPath::exists()
failed.
