Gingerbread 在32-bit 环境中编译不过的问题

下载Gingerbread 源代码在32-bit的环境中编译，会出现如下的build error：

You are attempting to build on a 32-bit system. Only 64-bit build environments are supported beyond froyo/2.2.

解决方法：

1. 在如下四个文件中：

./external/clearsilver/cs/Android.mk

./external/clearsilver/cgi/Android.mk 

./external/clearsilver/java-jni/Android.mk 

./external/clearsilver/util/Android.mk 

将下面的两行删除，

LOCAL_CFLAGS += -64

LOCAL_LDFLAGS += -64

并加入如下部分：

build_arch := $(shell uname -m)

ifeq (i686,$(findstring i686,$(build_arch)))

LOCAL_CFLAGS += -m32

LOCAL_LDFLAGS += -m32

else

LOCAL_CFLAGS += -64

LOCAL_LDFLAGS += -64

endif

2. 然后在./build/core/main.mk中 

将如下部分注释掉

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
