Can you help it out how to fix this issue?

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。

I encounter the same problem, have you fixed it yet?

*******************************************开始********************************************************

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

*******************************************结束********************************************************

     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

i found the android source 4.4.2 had no preblom,the isue dues to the ubuntu's environment,  lack one or more libraries; i built the source 4.4 in fsl's built ubuntu environment ,it successd.but it is a pity that  i do not know what libraries lack;
