hi. I'd like to use Xv extensions in my code. I think I have done everything in XFconfig-4 file (Load "extmod", etc.), I see in Xfree.0.log that the Xvideo extensions have been loaded. I add in my files the #include stuff (Xv.h and Xvlib.h), but when I try to compile and link my code I get "undefined reference to XvQueryExtensions" and stuff like that. I'm rather new at C++ programming, though I have some experience in Pascal. Will anybody be so kind as to lend me a trick? Luigi lgiancri@xxxxxxxxxxxxx NB. I forgot to tell that I've got a new NVIDIA Geforce4 440 and that I managed to install (after long) the source rpm drivers to get hw acceleration
