Hi all, I just added - (void)drawRect:(NSRect)rect { NSLog(@"MapView drawRect %@ ... _osmDrawing %d", NSStringFromRect(rect), _osmDrawing); [super drawRect:rect]; NSLog(@"After super drawRect:rect"); NSImage *image = [self image]; NSSize imageSize = [image size]; NSLog(@"asasa %@", self); // <--- this line NSLog(@"routeVisible: %d", _routeVisible); NSLog(@"routePath: %@", _routePath); } and get 2018-05-22 14:32:37.291 TimberNav[10763:10763] MapView drawRect {x = 0; y = 0; width = 817; height = 334} ... _osmDrawing 0 2018-05-22 14:32:37.291 TimberNav[10763:10763] After super drawRect:rect 2018-05-22 14:32:37.291 TimberNav[10763:10763] bums 2018-05-22 14:32:37.291 TimberNav[10763:10763] asasa (null) before the app crshes while accessing the ivar _routeVisible. So what does that mean? This looks like a very serious issue with the OS, gcc, objc to me!? This brings me back to the question of a reliably working Linux, GNUstep combo? If I could I would revert back to my ancient GNUstep tree (that worked at least) but the ancient GNUwtep sources do no longer build on Ubuntu which leaves me in a void. :-( Best wishes, Andreas |
