(2.6.25-git14 built fine, seemingly because there wasn't a tuner-core.c in that kernel.) LD .tmp_vmlinux1 drivers/built-in.o: In function `tuner_i2c_xfer_send_recv': drivers/media/common/tuners/tuner-i2c.h:61: undefined reference to `i2c_transfer' drivers/built-in.o: In function `tuner_i2c_xfer_send': drivers/media/common/tuners/tuner-i2c.h:39: undefined reference to `i2c_transfer' ... Divining options from the configuration log: I2C support (I2C) [M/n/y/?] m So, i2c is modular here. Video For Linux (VIDEO_DEV) [Y/n/m/?] y Video is built in, and since tuner-core.c is being built in as well, we can assume MEDIA_TUNER=y. drivers/media/common/tuners/Kconfig contains: config MEDIA_TUNER tristate default DVB_CORE || VIDEO_DEV depends on DVB_CORE || VIDEO_DEV which means it ends up being 'y' if either DVB_CORE or VIDEO_DEV is y (which one is as shown above.) There's a missing dependency here - it clearly depends on i2c, so that should also be in the "depends" line. -- Russell King Linux kernel 2.6 ARM Linux - http://www.arm.linux.org.uk/ maintainer of:
