Dear list,
I have a very simple program such as this:
int main(int argc, char** argv) {
osg::ArgumentParser arguments(&argc,argv);
cout << "start!" << endl;
osg::ref_ptr<osg::Node> loadedModel = osgDB::readNodeFiles(arguments);
if (!loadedModel)
{
cout << argv[0] <<": No data loaded" << endl;
return 1;
}
cout << "loaded" << endl;
}
I'm using the current trunk of OSG (updated 30 mins ago) on Ubuntu
8.04. The program hangs on the line with osgDB::readNodeFiles. I have
no idea why.
This is what GDB says:

This looks like there is a deadlock somewhere, otherwise
pthread_mutex_lock() wouldn't block. The same happens with cessna.osg
file from the sample files, however frames 8-10 are in osgdb_osg.so,
of course. Any ideas? I've already rebuilt OSG once, no luck.
Thank you!
