Android2.3源码编译问题已解决

$ repo init -u git://Android.git.kernel.org/platform/manifest.git
$ repo sync
下载完代码后，进行make，
$cd ~/mydroid
$make
却出现了如下错误：
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.
这是因为froyo/2.2默认只支持64-bit，看到有些网友还要去下载64-比他的操作系统，很是麻烦，于是通过不断搜索资料终于解决，

解决办法：
需要进行如下修改即可，
将
./external/clearsilver/cgi/Android.mk
./external/clearsilver/java-jni/Android.mk
./external/clearsilver/util/Android.mk
./external/clearsilver/cs/Android.mk
四个文件中的

# This forces a 64-bit build for Java6  
LOCAL_CFLAGS += -m64
LOCAL_LDFLAGS += -m64

# We use the host compilers because the Linux SDK build
# uses a 32-bit toolchain that can't handle -m64
注释掉，或者将“64”换成“32”
LOCAL_CFLAGS += -m32
LOCAL_LDFLAGS += -m32

然后，将
./build/core/main.mk 中的
ifneq (64,$(findstring 64,$(build_arch)))
改为：
ifneq (i686,$(findstring i686,$(build_arch)))
