makefile - Android kernel compilation -


for compiling kernel android below steps:

$ export arch=arm $ export subarch=arm $ export cross_compile=arm-eabi- $ cd omap $ git checkout <commit_from_first_step> $ make tuna_defconfig $ make 

i want change default configuration of kernel editing .config file (enabling flags multimedia , v4l2). when try perform "make", .config file overwritten default values , kernel compiled these values. tried editing .config file , performing "make oldconfig" same result.

any way edit .config file ?

.config file auto generated file, changing flags in .config not affect kernel configuration. change kernel configuration need open configuration window typing below command in kernel folder:

make arch=arm menuconfig

ps:: if using ubuntu 12.04 may error while executing 'make arch=arm menuconfig' command, rid of try (atleast worked me):
sudo apt-get install lib32ncurses5-dev
