error after building Linux source code for android
 

I have compiled the Linux kernel source for android. After building the source i got error,

that is, after

$ARCH=arm CROSS_COMPILE=/path/to/mydroid/prebuilt/linux-x86/toolchain/arm-eabi-4.4.0/bin/arm-eabi- make
i got:

CALL scripts/checksyscalls.sh
CHK include/linux/compile.h
Kernel: arch/x86/boot/bzImage is ready (#1)
Building modules, stage 2.
MODPOST 2283 modules
WARNING: modpost: Found 1 section mismatch(es).
To see full details build your kernel with:
'make CONFIG_DEBUG_SECTION_MISMATCH=y'
so i did the following:

root@ubuntu:~/common# make CONFIG_DEBUG_SECTION_MISMATCH=y
CHK include/linux/version.h
CHK include/linux/utsrelease.h
After even after this i got the same output

root@ubuntu:~/common# make
CHK include/linux/version.h
CHK include/linux/utsrelease.h
SYMLINK include/asm -> include/asm-x86
CALL scripts/checksyscalls.sh
CHK include/linux/compile.h

Building modules, stage 2.
MODPOST 2283 modules
WARNING: modpost: Found 1 section mismatch(es).
To see full details build your kernel with:
'make CONFIG_DEBUG_SECTION_MISMATCH=y'
The actual output should be

Kernel: arch/arm/boot/Image is ready
Kernel: arch/arm/boot/zImage is ready
Also i have executed "make" command many times, now there is no "image" in the arch/arm/boot/ directory. I tried to run the emulator with the image from arch/x86/boot but that didn't work. It gave me an error. The actual command is

./emulator -avd my_avd -kernel ~/common/arch/arm/boot/zImage -show-kernel -verbose
Now, as i don't have any image in /arch/arm/boot i did:

root@ubuntu:~/android-sdk-linux_x86/tools# ./emulator -avd avd1.5 -kernel ~/common/arch/x86/boot/bzImage -show-kernel -verbose
and i got this error:

I don't understand where i am doing wrong, i have done something stupid, please someone tell how can i solve this.? thank you!

It's looking for /usr/include/linux/ containing the kernel headers, I think. Don't understand your setup enough to be of much help. maybe set $INCLUDEDIR? Have you something to pass -I/path/to/kernel/headers to?

If everything works is lined up safely, you might manage by installing them.
make headers check
make headers install

if i execute the command for make, i get the following error, now what exactly is wrong and what will i have to do??(I was thinking of deleting all the downloaded files and download them again from start and carry the process to do this successfully, but that is very big process, in fact it took me days to download and do this). I just want to make it happen here somehow...

Emulator error with bzImage
 

Hello Preetam,
I was wondering how you got around this error. Could you guide me through this, I seem to be having the same issue

Hello Neelima,
Sorry for the late reply.

just let me know if you are building it for the emulator or phone??? & why?? by the way, i did all these to enable iptables inside Android kernel i.e. Android emulator(Android Eclair 2.1) & i had a working kernel image after some tries.
