clang: error: linker command failed with exit code 1 (use -v to see invocation)
build/core/host_shared_library_internal.mk:51: recipe for target 'out/host/linux-x86/obj32/lib/libart.so' failed

android kernel source code compilation error

I need to customize the kernel of android to run on my Nexus S.
So I download the kernel with branch name "remotes/origin/android-samsung-2.6.35-gingerbread"
I tried to follow the instruction here http://source.android.com/source/building-kernels.html to build the kernel. To do this, I need the cross compile tool.In my target android source code version android-2.3.5_r1, there is no such tool(no prebuilts/ folder). So I downloaded the version 4.1.2 and set up the tool as path prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin .
Then I tried to build my kernel, but I got the following error:
[root#localhost samsung]# make
scripts/kconfig/conf -s arch/arm/Kconfig
CHK include/linux/version.h
CHK include/generated/utsrelease.h
make[1]: `include/generated/mach-types.h' is up to date.

make[2]: *** [drivers/gpu/pvr] Error 2
make[1]: *** [drivers/gpu] Error 2
make: *** [drivers] Error 2
Should I just disable the "all warnings being treated as errors" to solve it? Or maybe I need a better toolchain?
PS: The tool chain of the master branch and branch 4.2 can not be used by me. Because it looks like they are made for a 64-bit OS while my linux is 32-bit

Do you have the path of ARCH=ARM and TOOLCHAIN pointing to the toolchain in \prebuilts folder?
make ARCH=ARM TOOLCHAIN=\<homeofAOSP>\prebuilt\.. herring_defconfig
make clean before you do the make

Android SREC_JNI compilation error

I am trying to compile SREC_JNI code in Eclipse (Windows 7), I got the code from here https://github.com/arthurv/srec
I am getting the following error
C:\android-ndk-r8c\ndk-build.cmd all
"Compile++ thumb : srec_jni <= android_speech_srec_MicrophoneInputStream.cpp
jni/srec_jni/android_speech_srec_MicrophoneInputStream.cpp:26:23: fatal error: utils/Log.h: No such file or directory
compilation terminated.
make: *** [obj/local/armeabi/objs/srec_jni/android_speech_srec_MicrophoneInputStream.o] Error 1
**** Build Finished ****
I would like to know where the utils folder is located and how to compile this SREC code.

This project is a fork of a component of Android OS. It should be built from the Android system tree and not with NDK as a standalone project.
You can find
utils/Log in platform/frameworks/native repository:
git clone https://android.googlesource.com/platform/frameworks/native

Argument list too long - Android 2.2.3_r1 build failed

I have downloaded the android 2.2.3_r1 and set up build environement.
I have made a special change to build the output in the USB drive by adding following line to buildspec.mk file and placing it in the source directory (the file has only that line as I want only to change the out directory).
OUT_DIR:=/media/SHANTHA/ANDROID
The build process is done issuing following commands in order:
source build/envsetup.sh
lunch full-eng
make -j4
When I run make -j4 it ends after fairly long time with following lines at the end of trace.
...
...
target Prelink: libthread_db (/media/SHANTHA/ANDROID/target/product/generic/symbols/system/lib/libthread_db.so)
target StaticLib: libwebcore (/media/SHANTHA/ANDROID/target/product/generic/obj/STATIC_LIBRARIES/libwebcore_intermediates/libwebcore.a)
make: execvp: /bin/bash: Argument list too long
make: *** [/media/SHANTHA/ANDROID/target/product/generic/obj/STATIC_LIBRARIES/libwebcore_intermediates/libwebcore.a] Error 127
make: *** Waiting for unfinished jobs....
shantha#shantha:~/ANDROID_S$
The trace indicates the error as make: execvp: /bin/bash: Argument list too long
It is a great help if someone can help me to solve this.

I had this problem too while building WebKit.
My solution was to download the kernel-sources, change line 14 in include/linux/binfmts.h from
#define MAX_ARG_STRLEN (PAGE_SIZE * 32)
to
#define MAX_ARG_STRLEN (PAGE_SIZE * 64)
compile and install the kernel and reboot.
However, the problem of this solution is that every running process needs more memory. But you could boot this kernel for building android only.
