If you do not know how to change from one user to the other or log in as a specific user, than your experience level is too low to build an LFS system. You'll run into many situations that are not explained in the book but taken for granted. A certain amount of existing knowledge is expected: LFS Prerequisites

My advise: get familiar with the linux command line and the way tools are being used before you start this project. You might want to start with the links provoded on the LFS Prerequisites page.

BTW: Why did you choose for an older ("outdated") LFS version and not the latest stable?

EDIT: I've asked the moderators to move this thread to the LFS sub-forum here on LQ.

You are contradicting yourself:

You need to give us detailed information about your problem. The following doesn't tell us anything:
Quote:
the thing is that i am getting some problem on it, the permission is getting denied.
- Which LFS chapter,
- Which command,
- What is the exact (error) message,
- Did you encounter any errors leading up to this problem.

About the liveCD: You are correct in stating that it cannot be used to build LFS 7.0 or greater. But the liveCD comes with its own set of problems (mainly when restarting after a reboot).

I would strongly advise not to use the liveCD but to use the current stable version. Make sure your host confirms to the specs in the book (Host System Requirements).

Ubuntu 12.04 and Debian 6 are good choices (Slackware as well, but I don't have any current experience with it).

Have a look here for some pointers:
- LFS 7.1 on Ubuntu 12.04
- Minimal Graphical Debian Host for LFS

Sudo?

The LFS book doesn't mention using sudo anywhere, you need to become the user the "normal" way (using su - <user> (as shown here: 4.3. Adding the LFS User (last command on page)).

can you please explain this "The commands in the remainder of this book must be performed while logged in as user root and no longer as user lfs. Also, double check that $LFS is set in root's environment"

It is chapter http://www.linuxfromscratch.org/lfs/...gingowner.html

What part don't you understand?

All of chapter 5 (up to and including 5.33) is done by user lfs, 5.34 is done as root user. $LFS should contain /mnt/lfs (or whatever you used).
