build/core/main.mk:76: ************************************************************

build/core/main.mk:79: ************************************************************
build/core/main.mk:80: *** stop。停止。

root@tianbaoxing-virtual-machine:/home/Android#

解决办法:

(1)找到build/core/main.mk文件，找到下面的代码段：

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 ************************************************************)

将第三行修改成ifneq (i686,$(findstring i686,$(build_arch)))

（2）找到下面的这几个文件：

/external/clearsilver/cgi/Android.mk

/external/clearsilver/cs/Android.mk

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

/external/clearsilver/util/Android.mk

修改其中的代码段： LOCAL_CFLAGS += -m64

LOCAL_LDFLAGS += -m64

改成：

LOCAL_CFLAGS += -m32

LOCAL_LDFLAGS += -m32
