could anyone point me what's going wrong here?

There's not enough info yet to point to anything specific.

Just a thought: Is $LFS (still) mounted?

From outside the chrooted environment, what do the following commands show you:
Code:

mount
ls -l $LFS

Thanks for the reply, ls $LFS is still "/mnt/lfs".

I revert everything and start from the beginning, but been blocking at compiling gcc pass1:

configure: error: in `/mnt/lfs/sources/gcc-build/x86_64-lfs-linux-gnu/libgomp':
configure: error: C compiler cannot create executables

it happened on my two Fedora 16 box and a RHEL6 box, they have the same result above.

That doesn't answer my question. /mnt/lfs is a mount point and will show when you execute ls $LFS.

Is the partition still mounted on that specific mount point? (2.4. Mounting the New Partition)

Is your host made fully compliant with the host requirements? Run the script mentioned in vii. Host System Requirements and post the outcome.

The blue entries might cause problems. I assume you are at the beginning of chapter 6 (6.4), with that in mind: I doubt these are the culprits because you do not mention any problems when building chapter 5.

How about my other/original question? (Is the partition still mounted on that specific mount point?).

Thanks for the point out, but my fedora 17 box is already updated to latest. Any suggestion to build the best environment for LFS?

I have no the original environment now, so I cannot sure about it.

The -i variable makes empty environment.
mkdir will fail because you haven't stated what directory to make.

Yes it does, but the rest of the command sets the environment (including PATH).

Also true, but you'll get another error message (mkdir: missing operand), besides that the ls command also doesn't seem to work.

@mercuyr: This thread seems to tackle an old problem and a new one.

Please tell us:
- which problem you are trying to tackle,
- which host you are using,
- which chapter you are,
- which error(s) you are facing.

If an error meassage is shown, please post it including a few lines before the error (have a look here: Help)

You mention 4 hosts:

Which one is it? You cannot use all four or use one and then switch to another (assuming the same LFS build).

The version check mentions ubuntu, which would make it 5 hosts (or is this from BackTrack?).

Did you remove the gcc source and build directories before retrying (have a look here: Second Important box).

It seems you are all over the place. I would suggest picking ONE host and start from scratch with the LFS build.

It is I have compiled the GCC in 4 hosts, every time was extracting source separately, not use any old dir.
the check version mentioned ubuntu is the backtrack host.

druuna 10-16-2012 06:08 AM

Assuming an Ubuntu based host, have a look here: LFS 7.1 on Ubuntu 12.04. Maybe you notice anything that you do different and can fix the problem that way. Your partition layout may differ, but that shouldn't be a problem.
