解决编译android2.2源码时出错的问题

编译android2.2的源码出现问题，问题如下：
1）Java代码
Checking build tools versions...
build/core/main.mk:72: ************************************************************
build/core/main.mk:73: You are attempting to build on a 32-bit system.
build/core/main.mk:74: Only 64-bit build environments are supported beyond froyo/2.2.
build/core/main.mk:75: ************************************************************
build/core/main.mk:76: *** stop. Stop.
解决办法：
#ifneq (64,$(findstring 64,$(build_arch)))
ifneq (i686,$(findstring i686,$(build_arch)))
$(warning ************************************************************)
$(warning You are attempting to build on a 32-bit system.)
$(warning Only 64-bit build environments are supported beyond froyo/2.2.)
$(warning ************************************************************)
$(error stop)
endif
修改以下文件：
external/clearsilver/cgi/Android.mk,
external/clearsilver/java-jni/Android.mk,
external/clearsilver/util/Android.mk,
external/clearsilver/cs/Android.mk
改为
disable LOCAL_CFLAGS += -m64
disable LOCAL_LDFLAGS += -m64
或
LOCAL_CFLAGS += -m32
LOCAL_LDFLAGS += -m32
2）Java代码
Install: out/host/linux-x86/framework/droiddoc.jar
target Generated: libclearsilver-jni <= out/host/common/obj/JAVA_LIBRARIES/clearsilver_intermediates/javalib.jar
host C: libclearsilver-jni <= external/clearsilver/java-jni/j_neo_util.c
In file included from /usr/include/features.h:378,
from /usr/include/string.h:26,
from external/clearsilver/java-jni/j_neo_util.c:1:
/usr/include/gnu/stubs.h:9:27: error: gnu/stubs-64.h: 没有那个文件或目录
make: *** [out/host/linux-x86/obj/SHARED_LIBRARIES/libclearsilver-jni_intermediates/j_neo_util.o] 错误 1
解决办法：
sudo apt-get install lib64z1-dev libc6-dev-amd64 g++-multilib lib64stdc++6
3）Java代码
打开此文件： 源码目录/build/core/main.mk   找到
# Check for the correct version of java
java_version := $(shell java -version 2>&1 | head -n 1 | grep '[ "]1\.6[\. "$$]')
ifeq ($(strip $(java_version)),)
$(info ************************************************************)
$(info You are attempting to build with the incorrect version)
$(info of java.)
$(info $(space))
$(info Your version is: $(shell java -version 2>&1 | head -n 1).)
$(info The correct version is: 1.6.)
$(info $(space))
$(info Please follow the machine setup instructions at)
$(info $(space)$(space)$(space)$(space)http://source.android.com/download)
$(info ************************************************************)
$(error stop)
endif
解决办法：
把里面的数字"6"改成"5",用JDK 1.5编译
