I have upgraded from fc5 to fc6 today and now i can not compile the driver for the dexxa webcam. I got it from sourceforge (qc-usb-0.6.4). After symlinking autoconf.h to config.h to get over the missing config.h error, i get the following: make -C "/lib/modules/2.6.18-1.2798.fc6/build" SUBDIRS="/tmpa/qc-usb-0.6.4" modules V=1 USER_OPT=""
