Hi Arnd, The better way to fix it is to do a patch like this one: http://git.linuxtv.org/cgit.cgi/media_tree.git/commit/?id=8abe4a0a3f6d4217b16a1a3f68cd5c72ab5a058e The problem with those dib drivers is that there's no way to latter remove them with rmmod. Using the above techinique, not only ranconfig compilation will work, but it will also allow module remove and having drivers with some frontends disabled. The drawback is that it is not a very trivial patch, so I did the changes only for devices that I have (all based on dib0700). Unfortunately, I don't have any device currently based on dib3000. I could work on such patchset, but someone would need to test it ;) Regards, Mauro -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

The dibusb_read_eeprom_byte function is defined in dibusb-common.c, but that file is not compiled for CONFIG_DVB_USB_DIBUSB_MB as it is for the other driver using the common functions, so we can get a link error: drivers/built-in.o: In function `dibusb_dib3000mc_tuner_attach': (.text+0x2c5124): undefined reference to `dibusb_read_eeprom_byte' (.text+0x2c5134): undefined reference to `dibusb_read_eeprom_byte' This changes the Makefile to treat the file like all the others in this directory, and enforce building dvb-usb-dibusb-common.o as a dependency.
