That's OK for the old code (and less so for the added code. :-} Meanwhile the files for the base package are available, too (even committed), so testing is actually possible. The patches applied cleanly and compiled with a few warnings. I found only minor things to fix: - dead but uncommented code in one case [if (foo && false) ...] - redundant assignments [float x = 0; x = foo->getFloatValue();] - compiler warnings I didn't thoroughly review (nor understand ;-) all the code, especially not the OSG parts, but I trust Tim. Also, the patches don't touch much other code, so I wouldn't be worried about it. The patch did not work for me at first, because (like other developers, I guess) I'm using /sim/sceneryloaded-override. This prevented that /sim/sceneryloaded ever became "true", while od_gauge waited exactly for that. This is meanwhile fixed (main.cxx). After that the code worked in both fg/plib and fg/osg, but in fg/plib I get a segfault on exit, which comes from RenderTexture.cpp. That's quite a hairy piece of code, and I'm not really competent to fix it. I checked on the net if newer RenderTexture implementations have that code part fixed, but this is not the case. #0 0x7773612f in ??

I don't say that the radar patch is buggy, it's just the old render-to-texture feature. (It's also not my graphics card driver, as Qt4 has no problems with RTT.) I would very much like to apply the patches, but I think the crash should be fixed first. (Or should the fg/osg patches go in, anyway?) m. ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
