下载了android 2.3源码，但是当编译的时候，遇到了如下问题：
build/core/main.mk:77: You are attempting to build on a 32-bit system. build/core/main.mk:78: Only 64-bit build environments are supported beyond froyo/2.2.
原因是编译gingerbread默认需要64位系统和Java6，在32位系统上修改下列文件能解决这个问题：
1. build/core/main.mk,查找下面部分
++++++++++++++++++++++++++++++++++++++++++
ifeq ($(BUILD_OS),linux) build_arch := $(shell uname -m) ifneq (64 ,$(findstring 64 ,$(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 endif +++++++++++++++++++++++++++++++++++
将64修改成 i686，注意 i必须是小写 。
2.依次修改下列文件
external/clearsilver/cgi/Android.mk external/clearsilver/java-jni/Android.mk external/clearsilver/util/Android.mk external/clearsilver/cs/Android.mk
在上述文件中查找如下变量，将m64修改成m32
LOCAL_CFLAGS += -m64 LOCAL_LDFLAGS += -m64
你也能在vim中快速替换:
：%s/m64/m32/g
