Building Android KitKat on 32 bit machine(ubuntu 10.04)

[Pradeep VR]

Hi friends am trying to build KitKat on 32 bit ubuntu 10.04 and getting below error:

host StaticLib: libandroidfw (out/host/linux-x86/obj/STATIC_LIBRARIES/libandroidfw_intermediates/libandroidfw.a)

ERROR: prebuilts/tools/gcc-sdk/../../gcc/linux-x86/host/x86_64-linux-glibc2.7-4.6/bin/x86_64-linux-ar only run on 64-bit linux

make: *** [out/host/linux-x86/obj/STATIC_LIBRARIES/libandroidfw_intermediates/libandroidfw.a] Error 1

As suggested in this post https://groups.google.com/forum/?fromgroups=#!topic/android-building/mlgtBY6a_BU I changed my build/core/config.mk as in below but could not succeed. 

HOST_JDK_TOOLS_JAR :=

else

HOST_JDK_TOOLS_JAR:= $(shell $(BUILD_SYSTEM)/find-jdk-tools-jar.sh)

ifeq ($(wildcard $(HOST_JDK_TOOLS_JAR)),)

$(error Error: could not find jdk tools.jar, please install JDK6, \

    which you can download from java.sun.com)

endif

endif

# Is the host JDK 64-bit version?

#HOST_JDK_IS_64BIT_VERSION :=

#ifneq ($(filter 64-Bit, $(shell java -version 2>&1)),)

#HOST_JDK_IS_64BIT_VERSION := true

#endif

#Commented above to support 32 bit machine

# It's called md5 on Mac OS and md5sum on Linux

ifeq ($(HOST_OS),darwin)

MD5SUM:=md5 -q

else

MD5SUM:=md5sum

endif

Thanks,

Pradeep.

That is an obsolete post.  See bullet 2 of http://source.android.com/source/building.html

You'd have to build 32 bit toolchains for host and arm.  Or if someone has some built already it might work.  Host toolchain version should gcc 4.6

Is it not possible to build the code by tweaking/modifying build scripts with existing host and toolchain? I used to build GingerBread by modifying some build scripts, hope we can build KitKat in the same way.

Before this I had built GingerBread by modifying some build scripts. Is it possible to build the KitKat just by editing some build scripts?

Earlier, AOSP used to contain the 32-bit toolchain. This is not present from the JellyBean release onwards. Only tweaking the build scripts would not do the job anymore.

Thanks Vishveshwar, will try it on 64-bit ubuntu.
