The source must be configured and depencies must have been created. Typically you can just install the kernel source package that comes with your distribution. If youre instead using virgin kernel in /usr/src/linux-x.y.zz, you must first copy kernel configuration file to /usr/src/linux-x.y.zz/.config, then go to the directory and run make oldconfig and make dep. This should create the missing linux/version.h file. Some more help for Redhat/Mandrake users: If you get a lot of errors on mandrake or red hat when you do a make, it may be because you didnt install a full development version, meaning your kernel sources are not there. This worked for me urpmi kernel-source urpmi kernel-headers urpmi kernel-doc urpmi is your friend, it will find the CD that it needs to get this. Some rpms may be installed already, big deal, do this then do a make, it worked on mandrake 8.2! - Q: And finally, I look for /dev/video* (to set the videodev on gnomemeeting) and I havent any videodevice. A: mknod /dev/video0 c 81 0 chmod a+r /dev/video0 ln -s /dev/video0 /dev/video - Q: quickcam.c:2099: too few arguments to function remap_page_range_R2baf18f2 Damian Ivereigh posted a patch to be able to compile the driver for RedHat 9.0 but I dont know how to do A: Due to qc-usb 0.5.1, this should be now fixed. If you still encounter this problem, and if youre using qc-usb, just compile it with command USER_OPT=-DHAVE_VMA=1 make all Otherwise (if youre using older qce-ga): 1. Download qce-ga-0.40d.tar.gz package and save the patch wget http:/www.ee.oulu.fi/tuukkat/quickcam/qce-gq-rh9.patch wget http:/www.ee.oulu.fi/tuukkat/quickcam/qce-ga-0.40d.tar.gz 2. Extract the package: tar xvfz qce-ga-0.40d.tar.gz 3. Enter the source directory cd qce-ga-0.40d 4. Apply the patch: patch -s -p1 ./qce-gq-rh9.patch 5. patch complains that the patch is reversed. Answer yes: Reversed (or previously applied) patch detected! Assume -R? n y 6. Then compile and install the driver normally make ./quickcam.sh - Q: I dont have permissions for /dev/video? A: Easiest way to add permissions is to do chmod a+rw /dev/video? as root. Altenatively, especially on Debian, users belonging to the video group can access video devices. In this case, you might instead prefer issuing addgroup video as root and then login as normal user. Check in which groups your are in with id -a - Q: My log files keep filling up (but the driver works fine)! A: use qcset debug=0 to disable all possible messages. If it doesnt help, send e-mail to mailing lists showing the exact error message that fills your logs. (especially frame lost message is uninteresting, it is known to happen with some programs and will be fixed later. - Q: quickcam.o: kernel-module version mismatch quickcam.o was compiled for kernel version 2.4.18 while this kernel is version 2.4.18-686-smp. A: Then edit Makefile in the kernel source directory and change the line 4 from EXTRAVERSION = to EXTRAVERSION = -686-smp -or if this doesnt help- Go to /usr/src/linux-2.4/include/linux/version.h and change the UTS_RELEASE to match the output of uname -r on the command line (should be 2.4.18-686-smp). Then recompile the module and then the insmod will work perfectly :) from Mark - Q: I want to reverse engineer an USB camera. How? A: Run *ugh* Windoze *cough* drivers with a USB stream capture program, like /projects/usbsnoop/ Then send the same commands to the camera from Linux. - Q: I added IEEE1394 card and now Quickcam doesnt work? A: The card driver overwrites /dev/video0.2, use insmod ./quickcam.o video_nr=3 and then /dev/video3 with Quickcam. Create /dev/video3 with mknod if necessary. (from Makarand) - Error:make2: Entering directory /opt/uClinux-dist/uClibcRules.mak:25: Config: No such file or directoryYou didnt read the README, did you. =)Choose a configuration file in extras/Config/ and then run ln -s ./extra/Configs/Config. ./Config A: The solution to this seems obvious. I cp ./vendors/Lineo/uCdimm/config.uClibc ./vendors/Lineo/uCsimm and make again with the same settings as above. The library compile bombs out a little further along. - Qm68k-elf-gcc -Wall -fno-builtin -nostdinc -m68000 -nostdinc -I././././include -I/usr/local/lib/gcc-lib/m68k-elf/2.95.3/include -I. -D_LIBC -m68000 -O2 -g -fomit-frame-pointer -DCONFIG_LINEO -fno-builtin -msep-data -DEMBED -I/opt/uClinux-dist/lib/uClibc/include -I/opt/uClinux-dist -Dlinux -D_linux_ -D_uClinux_ -Dunix -I/opt/uClinux-dist/linux-2.4.x/include -DNDEBUG -DL_ioperm syscalls.c -c -o ioperm.osyscalls.c:767: sys/io.h: No such file or directorymake6: * ioperm.o Error 1 A recent posting suggests a solution. Rather than copy individual missing files, I untared an older uClibc-snapshot into ./uClibc and then overcopied with the uClibc-0.9.10 tree. The make goes further still and stops with. use the uClib of uClinux-dist-20050311.tar.gz replace it,because I can make it in that. - Qm68k-elf-gcc -Wall -fno-builtin -c crti.S -o crti.ocp crti.o ././././lib/cp: cannot create regular file ././././lib/crti.o: No such file or directorymake6: * crti.o Error 1 A Now Im lost.
