I am using 3.10.x kernel tree. My kernel module needs config VIDEOBUF2. That is defined in drivers/media/v4l2-core/Kconfig: # Used by drivers that need Videobuf2 modules config VIDEOBUF2_CORE select DMA_SHARED_BUFFER tristate So I put 'CONFIG_VIDEOBUF2_CORE=y' in my Kernel config file and compile. From the Kconfig it has CONFIG_VIDEOBUF2_CORE has no dependency and I think adding CONFIG_VIDEOBUF2_CORE=y to my kernel config should work. I am modify the right kernel config file since I set other flags like CONFIG_VIDEO_DEV=y and that works. The generated .config does not contain 'CONFIG_VIDEOBUF2_CORE=y' and the compilation fails with a bunch of undefined reference to `vb2_buffer_done' undefined reference to `vb2_buffer_done' undefined reference to `vb2_buffer_done' undefined reference to `vb2_buffer_done' I really appreciate if someone can help me with this. Thank you. _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
