3,install Oracle Java JDK
download address: http://www.oracle.com/technetwork/java/javasebusiness/downloads/java-archive-downloads-javase6-419409.html
choose:jdk-6u38-linux-x64.bin
$ sudo mkdir /usr/local/java

$ cd /usr/local/java
$ chmod +x jdk-6u38-linux-x64.bin
$ ./jdk-6u38-linux-x64.bin
configure JAVA_HOME and PATH in system environment:

4,install some to support 32bit lib and software
sudo apt-get install ia32-libs
as no source for ia32-libs installtion,it can be replaced for 3 package:
sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0
5,install development tool, lib, and etc for ubuntu14.04
sudo apt-get install build-essential sudo apt-get install make sudo apt-get install gcc sudo apt-get install g++ sudo apt-get install libc6-dev sudo apt-get install patch sudo apt-get install texinfo sudo apt-get install libncurses-dev sudo apt-get install git-core gnupg sudo apt-get install flex sudo apt-get install bison sudo apt-get install gperf sudo apt-get install libsdl-dev sudo apt-get install libesd0-dev sudo apt-get install libwxgtk2.6-dev (failed)(install 2.8) sudo apt-get install build-essential sudo apt-get install zip sudo apt-get install curl sudo apt-get install ncurses-dev sudo apt-get install zlib1g-dev sudo apt-get install valgrind sudo apt-get install python2.5(failed to install, can ignore) sudo apt-get install libgtk2.0-0:i386 sudo apt-get install libpangox-1.0-0:i386 sudo apt-get install libpangoxft-1.0-0:i386 sudo apt-get install libidn11:i386 sudo apt-get install gstreamer0.10-pulseaudio:i386 sudo apt-get install gstreamer0.10-plugins-base:i386 sudo apt-get install gstreamer0.10-plugins-good:i386 sudo apt-get install gstreamer0.10-ffmpeg:i386(failed to install can ignore)
6. down A20 source code to build in ubuntu14.04
this source code is contain cross-tool, it can save my time to build an another cross-tool.
7. "mkimage" command not found - U-Boot images will not be built
sudo apt-get install u-boot-tools
8./bin/bash: jar: command not found
$ cd /usr/bin
$ sudo ln -s -f /usr/local/java/jdk1.6.0_38/bin/jar
9. /usr/include/stdlib.h:760:34: fatal error: bits/stdlib-bsearch.h: No such file or directory
sudo apt-get install libc6-dev:i386 [it will remove install for os 64 bit and reinstall for i386]
sudo apt-get install build-essential
sudo apt-get install gcc-multilib
sudo apt-get install ubuntu-desktop [because uninstall ibus, make ubuntu14.04 lose systemsetting item, reinstall ubuntu-desktop could solve this problem]
10. BEGIN failed--compilation aborted at external/webkit/Source/WebCore/make-hash-tools.pl line 23.
