$ sudo apt-get update
$ sudo apt-get install git git-core pkg-config make autoconf libtool g++\
tcl unzip libyajl-dev libyajl1 qt4-qmake libsqlite3-dev curl
$ sudo apt-get install gperf bison libglib2.0-dev libssl-dev libxi-dev\

$ sudo apt-get build-dep qt4-qmake
2.webosインストールスクリプトのダウンロード
https://github.com/openwebos/build-desktop#downloading
3.webosをダウンロードしてインストールする
./build-webos-desktop.sh
sudo ./install-webos-desktop.sh
三、webosを実行して、実行する时まだいくつかのエラーがあって、もしエラーを排除するならば、インタフェースが出るべきです.

How to Run on Ubuntu Linux

Please note that this version of the build does not provide full runtime functionality.
1) Change to the folder where the build-desktop scripts are located (if necessary).
2) Start up the service bus:

    $ ./service-bus.sh start

The message  hub daemons started  indicates success. You can safely ignore error messages.
3) The first time you start, you'll need to create a default account:

    $ ./service-bus.sh init

In order for the FileCache and Email to work properly, "user_xattr"attribute needs to be set on the filesystem where "luna-desktop-binaries/staging"is located. The command to set the attribute is given below.

$ sudo mount / -o remount,user_xattr

Note that the above command will set the attribute temporarily on the filesystem, it will be reset to default settings when machine is rebooted. If you want to make it permenant, edit the file/etc/fstab to add the attribute. Please refer the Ubuntu documentation for more details.
4) Start up the native webOS services on the service bus:

    $ ./service-bus.sh services

The message  Services started!  indicates success. You can safely ignore error messages.
5) Run luna-sysmgr (ideally from a separate terminal shell window to keep the luna-sysmgr output separate from the service-bus logging)

    $ ./run-luna-sysmgr.sh

You can safely ignore the messages from LunaService.
6) When you are finished running luna-sysmgr, stop the service bus:

   $ ./service-bus.sh stop
