Why I can not bitbake success?

[bobking]

I want to build image for imx6ulevk.My environment is Ubuntu14.04,and I followed the document Freescale_Yocto_Project_User's_Guide.pdf step by step,I am sure I had installed the packages and set up the Yocto project.But when I use command:bitbake fsl-image-gui,it never succeed.It would take more than 20 hours,and give me many Warnings:Failed to fetch URL...,and than will stop about can not find some file's error.

My question is :

     1.It take so much time ,is it normal?

     2.How can I build image successfully?what's wrong with me ?

Note:

I not use Proxy Software,so my net could not access Foreign websites.

Hello,

  In order to build Linux image under Yocto you need significant

resources. It may be recommended to apply 64-bit Linux host (virtual
machine) with 6 GB of RAM for images with GUI.

  First, you may try to build minimal system.

As for using proxy - it may be needed. Please look at section 2 (How do I download

the Android source code behind a firewall?) of “Android_Frequently_Asked_Questions.pdf”

how to configure proxy.
