Just use the menuconfig or xconfig targets. Maybe > the kernel kconfig behavior has changed? Hmm... I did a test here with RHEL 2.6.18 kernel: $ make menuconfig make -C /home/v4l/master/v4l menuconfig make[1]: Entrando no diretório `/home/v4l/master/v4l' /usr/src/kernels/2.6.18-125.el5-x86_64//scripts/kconfig/mconf ./Kconfig # # configuration written to .config # *** End of Linux kernel configuration. *** Execute 'make' to build the kernel or try 'make help'. $ grep CX88 v4l/.config CONFIG_VIDEO_CX88=m CONFIG_VIDEO_CX88_ALSA=m CONFIG_VIDEO_CX88_BLACKBIRD=m CONFIG_VIDEO_CX88_DVB=m CONFIG_VIDEO_CX88_MPEG=y CONFIG_VIDEO_CX88_VP3054=m So, I got the buggy .config Another test with 2.6.27: $ make menuconfig make -C /home/v4l/master/v4l menuconfig make[1]: Entrando no diretório `/home/v4l/master/v4l' ./scripts/make_kconfig.pl /usr/src/kernels/v2.6.27.4/ /usr/src/kernels/v2.6.27.4/ Preparing to compile for kernel version 2.6.27 VIDEO_PXA27x: Requires at least kernel 2.6.29 USB_STV06XX: Requires at least kernel 2.6.28 /usr/src/kernels/v2.6.27.4.i5400//scripts/kconfig/mconf ./Kconfig # # configuration written to .config # *** End of Linux kernel configuration. *** Execute 'make' to build the kernel or try 'make help'. make[1]: Saindo do diretório `/home/v4l/master/v4l' [v4l@pedra master]$ grep CX88 v4l/.config CONFIG_VIDEO_CX88=m CONFIG_VIDEO_CX88_ALSA=m CONFIG_VIDEO_CX88_BLACKBIRD=m CONFIG_VIDEO_CX88_DVB=m CONFIG_VIDEO_CX88_MPEG=m CONFIG_VIDEO_CX88_VP3054=m With 2.6.27, everything is OK. So, it seems that a fix at some kernel between 2.6.22 and 2.6.27 changed (or fixed) the Kconfig behaviour. I suspect that the better fix for this would be to run something like: cat .config|sed s,'=y','=m' For kernels older than 2.6.27. Maybe Hans can give us a hint on what kernel this issue were solved, with his build environment.
