android2.3.4----1.ubuntu12.04 64位编译android2.3.4

原文地址：http://blog.chinaunix.net/uid-26009923-id-4035398.html
1. 编译工具链
解压 tools 下的 
arm-linux-gcc-4.3.2.tgz  
arm-none-linux-gnueabi-arm-2008q3-72-for-linux.tar.bz2 
到/opt/6410/android目录下

cong@ubuntu:/opt/6410/android$ ls
4.3.2 arm-none-linux-gnueabi

2. 编uboot (板子是256M的nand)
用的编译器是在arm-linux-gcc-4.3.2中的

cong@ubuntu:/work/an6410/uboot$ vi Makefile
 161 CROSS_COMPILE =/opt/6410/android/4.3.2/bin/arm-none-linux-gnueabi-
 162 export CROSS_COMPILE
cong@ubuntu:/work/an6410/uboot$ make smdk6410_config
Configuring for smdk6410 board...
cong@ubuntu:/work/an6410/uboot$ make

生成 u-boot.bin
3.编译kernel
修改Makefile

cong@ubuntu:/work/an6410/kernel$ vi Makefile
 192 ARCH ?= arm
 193 CROSS_COMPILE ?= /opt/6410/android/arm-none-linux-gnueabi/bin/arm-none-linux-gnueabi-
make -j4

4. 编译android 
机子是 ubuntu 12.04LTS  64位,所以需要修改这几个Android.mk
4.1 按手册修改Android.mk

./external/clearsilver/cgi/Android.mk
./external/clearsilver/java-jni/Android.mk
./external/clearsilver/util/Android.mk
./external/clearsilver/cs/Android.mk
找到
LOCAL_CFLAGS += -m32
LOCAL_LDFLAGS += -m32
替换为
LOCAL_CFLAGS += -m64
LOCAL_LDFLAGS += -m64
记得保存文件。
第二步：
修改文件 ./build/core/main.mk
找到
ifneq (i686,$(findstring i686,$(build_arch)))
替换为
ifneq (64,$(findstring 64,$(build_arch)))

4.2 出错处理
a. 添加 -fpermissive

frameworks/base/libs/utils/RefBase.cpp: In member function ‘void android::RefBase::weakref_type::trackMe(bool, bool)’:
frameworks/base/libs/utils/RefBase.cpp:483:67: error: passing ‘const android::RefBase::weakref_impl’ as ‘this’ argument of ‘void android::RefBase::weakref_impl::trackMe(bool, bool)’ discards qualifiers [-fpermissive]

解决方法:
frameworks/base/libs/utils/Android.mk
 60 LOCAL_CFLAGS += -DLIBUTILS_NATIVE=1 $(TOOL_CFLAGS) –fpermissive

b. 这个需要改javadoc

Could not load 'clearsilver-jni'
java.library.path = out/host/linux-x86/lib
make: *** [out/target/common/docs/doc-comment-check-timestamp] Error 45

解决方法: 先是将默认工具链中的javadoc替换成jdk1.5的这个地方是可以编过去的.
但是在接下来的编译中还会出现错误
c. 终极大招
默认的工具链jdk1.6.0_23好像是32位的,所以需要替换为64位的,
下载jdk-6u35-linux-x64.bin,然后解压到android源码目录下
修改build-android

  6 #export PATH=$PWD/jdk1.6.0_23/bin:$PATH
  7 export PATH=$PWD/jdk1.6.0_35/bin:$PATH

d. 接下来就是一些小问题了

prebuilt/linux-x86/sdl/include/SDL/SDL_syswm.h:55:22: fatal error: X11/Xlib.h: No such file or directory
compilation terminated.
make: *** [out/host/linux-x86/obj/EXECUTABLES/emulator_intermediates/android/main.o] Error 1

解决方法:
    sudo apt-get install libx11-dev

e. 将 -Werror去掉

<command-line>:0:0: error: "_FORTIFY_SOURCE" redefined [-Werror]
<built-in>:0:0: note: this is the location of the previous definition
cc1plus: all warnings being treated as errors
make: *** [out/host/linux-x86/obj/EXECUTABLES/obbtool_intermediates/Main.o] Error 1
