一、参考文档:

        http://processors.wiki.ti.com/index.php/Building_QT_Projects

二、基本操作流程:
    1. After Installing your host Ubuntu and then the SDK on your host machine: [How to install Ubuntu and your SDK]
        在你电脑上安装Ubuntu及SDK。
    2. Create a new directory on your Ubuntu 10.04 host.
        在Ubuntu中创建一个目录,叫:hello-world。
        user@user-desktop:~$mkdir hello-world
    3. Change to that directory
        进入刚刚创建的目录 。
        user@user-desktop:~$cd hello-world
    4. Source the environment setup to get access to qmake and the gcc compiler
        导入环境变量,这样你才能够使用qmake和gcc编译器。
        user@user-desktop:~/hello-world$ source /home/user/ti-sdk-am335x-evm-05.03.00.00/linux-devkit/environment-setup
    5. Create a new file: hello-world.cpp and copy in the following source code to hello-world.cpp
        创建hello-world.cpp文件,并将以下源代码拷入文件中。
        #include <QApplication>
        #include <QLabel>
    
        int main(int argc, char **argv)
        {
            QApplication app(argc, argv);
            
            QLabel label("Hello World!");
            label.show();
            
            return app.exec();
        }
    6. Execute the following commands: (If you already have a project file skip step 1)
        执行以下命令:(如果你已经有一个工程项目文件,请跳过这一步)
        [linux-devkit]:~/hello-world> qmake -project // The first command creates a project file: hello-world.pro.
        [linux-devkit]:~/hello-world> qmake // The second generates a makefile based on the project file.
        [linux-devkit]:~/hello-world> make // The third compiles and builds the project.
    
    7. This is what you have just created
        这是刚刚你创建的文件,或者生成的文件。
        [linux-devkit]:~/hello-world> ls
        hello-world  hello-world.cpp  hello-world.o  hello-world.pro  Makefile
    8. copy the hello-world binary over to your file system and run hello-world on your target.
        将hello-world二进制文件拷入你的文件系统,并在目标机器上运行。
