Android 2.3编译不过的问题

刚从谷歌服务器下载的gingerbread源代码，发现编译不过：

 

Checking build tools versions...
build/core/main.mk:77: ************************************************************
build/core/main.mk:78: You are attempting to build on a 32-bit system.
build/core/main.mk:79: Only 64-bit build environments are supported beyond froyo/2.2.
build/core/main.mk:80: ************************************************************
build/core/main.mk:81: *** stop。 停止。

 

请查看一下几个步骤

 

1 安装几个软件：

   sudo apt-get install lib64z1-dev libc6-dev-amd64 g++-multilib lib64stdc++6

 

 

2 使用32位也可以编译（一直都是32 bit system）

   修改build/core/main.mk

#ifneq (64,$(findstring 64,$(build_arch)))
ifneq (i686,$(findstring i686,$(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

 

3 使用java1.5也可以编译 （2.2也是1.5 version)

   修改build/core/main.mk

java_version := $(shell java -version 2>&1 | head -n 1 | grep '[ "]1/.5[/. "$$]')

javac_version := $(shell javac -version 2>&1 | head -n 1 | grep '[ "]1/.5[/. "$$]')
