解决Android Gingerbread (2.3) 编译错误

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
