"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.

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.
