android4.4.2编译过程会出现sepolicy错误报告，Invalid policyvers specified: 26，how to resolve it?

正确答案：

方案一：重装系统可解决上述问题，本人已验证过。

方案二：   在源码目录进行内容查找，在external/checkpolicy//checkpolicy.c文件中，打开该文件，在main函数的switch 语句的case ‘c’代码块中找到了错误提示行。

代码修改如下：在long int n = strtol(optarg, NULL, 10);后面再加上errno = 0;

重新编译源码，顺利通过，模拟器运行正常，上网也ok。

This error because of a code bug in /external/checkpolicy/checkpolicy.c

You can search the "Invalid xxx" characters in this file, and you will find that after a function call of strtol, the errno checking is not typically for ERANGE and EINVAL only, so other errno made by early function calls will also make your code run the error code path.

Fix the bug then you can compile the source code in any environment

the correct install steps:

1、install ubuntukylin-14.04.1-desktop-amd64.iso

2、install jdk1.6.0_45.bin

3、install packages:

sudo apt-get update

sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0

sudo apt-get install bison g++-multilib git gperf libxml2-utils

sudo apt-get install curl flex gperf u-boot-tools

$ sudo apt-get install uuid uuid-dev zlib1g-dev liblz-dev liblzo2-2 liblzo2-dev

$ sudo add-apt-repository ppa:git-core/ppa

$ sudo apt-get update

$ sudo apt-get install git-core curl subversion  u-boot-tools

4、complete successfully!!!!!!!

note:执行完第1步骤后最好不要更新系统软件，有可能会出现我编译时出现的问题。以上我遇到的问题可能是更新系统软件造成的，无法修复，后来我在断网的情况下安装ubuntukylin-14.04.1-desktop-amd64.iso后，再联网安装第2、3步骤后，编译Android4.4成功。以上步骤完成后，checkpolicy命令应该可以正常使用，为保险起见可以先测试下checkpolicy命令是否可用（可以拷贝编译生成的checkpolicy,或者安装checkpolicy工具，我是拷贝编译生成的checkpolicy进行测试的），步骤如下：

1、cp ~/works/myandroid4.4-fsl/fsl-Android4.4.2-V1.0/out/host/linux-x86/bin/checkpolicy ~/tools/

note:~/works/myandroid4.4-fsl/fsl-Android4.4.2-V1.0/：我的Android4.4源码路径， ~/tools/：我创建的文件夹

2、cp ~/works/myandroid4.4-fsl/fsl-Android4.4.2-V1.0/out/target/product/sabresd_6dq/obj/ETC/sepolicy_intermediates/policy.conf ~/tools/

note:sabresd_6dq为我的编译平台

3、打开终端，输入命令：

wangwei@wangwei-vm:~$ cd tools/

wangwei@wangwei-vm:~/tools$ ls

checkpolicy  policy.conf

wangwei@wangwei-vm:~/tools$ ./checkpolicy -M -c 26 -o sepolicy policy.conf

./checkpolicy:  loading policy configuration from policy.conf

./checkpolicy:  policy configuration loaded

./checkpolicy:  writing binary representation (version 26) to sepolicy

wangwei@wangwei-vm:~/tools$ ls

checkpolicy  policy.conf  sepolicy

wangwei@wangwei-vm:~/tools$

note:可以发现tools文件夹下多了sepolicy文件，说明checkpolicy命令可用，之后再编译Android4.4就不会出现如下问题：

Invalid policyvers specified: 26

usage:  out/host/linux-x86/bin/checkpolicy [-b] [-d] [-U handle_unknown (allow,deny,reject)] [-M][-c policyvers (15-29)] [-o output_file] [-t target_platform

(selinux,xen)][input_file]
make: *** [out/target/product/sabresd_6dq/obj/ETC/sepolicy_intermediates/sepolicy] Error 1

     以上编译android4..4没问题，但编译Android4.2还会出现缺少库的问题，以下方法可解决：

the correct install steps:

1、install ubuntukylin-14.04.1-desktop-amd64.iso

2、install jdk1.6.0_45.bin

3、install packages:

sudo apt-get update

sudo apt-get install libc6-dev-i386 zlib1g-dev g++-multilib lib32z1-dev lib32ncurses5-dev libxml2-utils uuid-dev

sudo apt-get install dpkg-dev

sudo apt-get install git gnupg flex bison gperf build-essential zip curl libc6-dev libncurses5-dev:i386 x11proto-core-dev libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-glx:i386 libgl1-mesa-dev g++-multilib mingw32 tofrodos python-markdown libxml2-utils xsltproc zlib1g-dev:i386

sudo apt-get install uuid uuid-dev zlib1g-dev liblz-dev liblzo2-2 liblzo2-dev

sudo apt-get install git-core curl subversion

sudo apt-get install u-boot-tools

sudo ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1 /usr/lib/i386-linux-gnu/libGL.so

sudo apt-get install liblzo2-dev:i386 uuid-dev:i386

sudo apt-get install libswitch-perl

4、同样，为保险起见可测试下checkpolicy是否可用
