Bug 475158 – sys-kernel/genkernel with sys-kernel/gentoo-sources-3.9.8 - drivers/built-in.o: In function `vb2_fop_mmap': (.text+0xd1ccd): undefined reference to `video_devdata'

• Status: RESOLVED OBSOLETE
• Product: Gentoo Hosted Projects

[Description Raymond Jennings 2013-06-28 23:01:50 UTC]

I tried to compile a kernel with genkernel, and turned on usb video support.

The link stage choked on undefined references, and my hunches tell me it's due to a missed dependency somewhere in the kernel configuration.

Reproducible: Always

Steps to Reproduce:
1.  use supplied configuration
2.  compile the kernel with it

Actual Results:  
link failure

Expected Results:  
a successful kernel build

This appears to be a regression, since I've had this enabled before without trouble.  May want to give upstream's stable team a poke in the process.

fixed kernel configuration

Here's a manually patched kernel configuration that makes the problem go away.

Diffing the two should probably help finger which dependencies need added to the Kconfigs.

That's not the only one though.

Don't forget about the USB stuff.

I had some USB stuff set to Y, but one of the (U/O)HCI thingies to M

genkernel configs have been refreshed and no such issues currently appear to be present
