"missing kernel .config file" error while compiling linux source code for android
I am compiling linux source code for android emulator. I did all the prerequisites. I extracted the .config file from the android emulator(1.5) with following commands
$adb pull /proc/config.gz . # get compressed .config file from the emulator. $gunzip config.gz # uncompress it. $cp config .config # rename it into .config And now the config file is in my /android-sdk-linux_x86/tools directory. I have modified it according to my needs. Now when i try to make(for building and cross-compiling the linux source) i get the following error. root@ubuntu:~# cd common root@ubuntu:~/common# ARCH=arm CROSS_COMPILE=/home/preetam/mydroid/prebuilt/linux-x86/toolchain/arm-eabi-4.4.0/bin/arm-eabi- make HOSTCC scripts/basic/fixdep scripts/basic/fixdep.c: In function ‘traps’: scripts/basic/fixdep.c:377: warning: dereferencing type-punned pointer will break strict-aliasing rules scripts/basic/fixdep.c:379: warning: dereferencing type-punned pointer will break strict-aliasing rules HOSTCC scripts/basic/docproc HOSTCC scripts/basic/hash HOSTCC scripts/kconfig/conf.o scripts/kconfig/conf.c: In function ‘conf_askvalue’: scripts/kconfig/conf.c:105: warning: ignoring return value of ‘fgets’, declared with attribute warn_unused_result scripts/kconfig/conf.c: In function ‘conf_choice’: scripts/kconfig/conf.c:307: warning: ignoring return value of ‘fgets’, declared with attribute warn_unused_result HOSTCC scripts/kconfig/kxgettext.o SHIPPED scripts/kconfig/zconf.tab.c SHIPPED scripts/kconfig/lex.zconf.c SHIPPED scripts/kconfig/zconf.hash.c HOSTCC scripts/kconfig/zconf.tab.o HOSTLD scripts/kconfig/conf scripts/kconfig/conf -s arch/arm/Kconfig *** *** You have not yet configured your kernel! *** (missing kernel .config file) *** *** Please run some configurator (e.g. "make oldconfig" or *** "make menuconfig" or "make xconfig"). *** make[2]: *** [silentoldconfig] Error 1 make[1]: *** [silentoldconfig] Error 2 CHK include/linux/version.h UPD include/linux/version.h Generating include/asm-arm/mach-types.h make: *** No rule to make target `include/config/auto.conf', needed by `include/config/kernel.release'. Stop. root@ubuntu:~/common# i am following instructions from http://linuxclues.blogspot.com/2010/...l-android.html Here "common" directory is where my android kernel source resides. The error is regarding the .config file. where should i place the .config file? or how to solve this problem? please help. thank you! |
The .config should be in the top-level directory.
Which, in this case, would be ~/common. |
