Hi all, compiling media_build on my openSUSE 13.1 machine worked without errors, but issued some warnings, finally leading to (dmesg): [97792.189678] usb 2-1.6: new high-speed USB device number 10 using ehci-pci [97792.276140] usb 2-1.6: New USB device found, idVendor=2040, idProduct=0264 [97792.276147] usb 2-1.6: New USB device strings: Mfr=3, Product=1, SerialNumber=2 [97792.276151] usb 2-1.6: Product: soloHD [97792.276154] usb 2-1.6: Manufacturer: HCW [97792.276157] usb 2-1.6: SerialNumber: 0013813833 [97792.445273] em28xx: Unknown symbol v4l2_clk_unregister_fixed (err 0) [97792.445319] em28xx: Unknown symbol __v4l2_clk_register_fixed (err 0) The DVB stick seems to be well recognized (-> em28xx). The only reference to v4l2_clk_unregister_fixed I could find was inside em28xx-camera.c. modprobe em28xx yields the same results. Do you have any hints how to solve the problem? Cheers Mit freundlichen Grüßen Klaus Eicheler
