按照我的文章：http://blog.csdn.NET/zangcf/article/details/23566999在ubuntu 14.04上搭建Android编译环境，编译过程会出以下两个错误：

1，Can't locateSwitch.pm in @INC (you may need to install the Switch module) (@INC contains:/etc/perl /usr/local/lib/perl/5.18.2 /usr/local/share/perl/5.18.2/usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.18 /usr/share/perl/5.18/usr/local/lib/site_perl .) at external/webkit/Source/WebCore/make-hash-tools.plline 23.

make[3]: ***[out/target/product/project/obj/STATIC_LIBRARIES/libwebcore_intermediates/Source/WebCore/html/DocTypeStrings.cpp]Error 2

2， Copy xml: out/target/product/project/system/etc/epo_conf.xml
/bin/bash: xmllint: command not found
make[3]: *** [out/target/product/project/system/etc/epo_conf.xml] Error 127

需要补充安装两个东西：

sudo apt-getinstall libswitch-perl  

sudo apt-get  install libxml2-utils

之后，就可以正常编译android系统了。
