[SOLVED] lfs 10.1 | Entering the Chroot Environment | Ubuntu 20.04

farhatb · 03-26-2021, 06:34 PM

Hello,
Host distribution: Ubuntu 20.04
LFS book version: 10.1
Section where the problem was encountered: 7.4. Entering the Chroot Environment
Error:

Code:

root@farhat-pc:/mnt/lfs# chroot "$LFS" /usr/bin/env -i   \
>     HOME=/root                  \
>     TERM="$TERM"                \
>     PS1='(lfs chroot) \u:\w\$ ' \
>     PATH=/bin:/usr/bin:/sbin:/usr/sbin \
>     /bin/bash --login +h
chroot: failed to run command ‘/usr/bin/env’: Not a directory

$LFS/bin/usr/env:

Code:

root@farhat-pc:/mnt/lfs# ls -lah usr/bin/env
-rwxr-xr-x 1 root root 265K mars 26 15:50 usr/bin/env

'$LFS/usr/env' is a file file not a directory!!
I am sure that I have followed the two previous section 7.2 && 7.3
Any hint please?

I'm experiencing the same thing, building on top of OpenSuse.

Yes, sure

Keith Hedger · 03-27-2021, 08:51 AM

is $LFS actually mounted?

Keith Hedger · 03-27-2021, 08:53 AM

what is at $LFS/dev , $LFS/proc etc ie are the virtual systems mounted, what are the mount options for $LFS

I'm experiencing the same exact issues with $LFS mounted, the proper environment variables set, and virtual systems mounted according to the instructions in the 10.1 guide.
https://www.linuxquestions.org/quest...ry-4175692690/

It's a bit odd that both of us, on the same day, ran into the same issue, at the same exact point in the process.

I had a similar problem when 1st using the new build system, it was the lib folders, are you using /lib64 and /usr/lib64 ( presuming a 64 bit machine ) or are you using /lib and /usr/lib ?

On my system /lib is symlink to /lib64 and /usr/lib is symlink to /usr/lib64.

Very interesting and insightful!
So, it appears that I'm using /lib and /usr/lib for all but the following:
Inside /mnt/lfs/lib64 are ld-linux-x86_64.so.2 and ld-lsb-x86-64.so.3
/mnt/lfs/usr/lib64 contains several libstdc++ libraries

What do you think is the best way to proceed from here since there are libs in both?

My only fix was to start from scratch, and make sure the links were in at the begining sorry

Ouch...

probably this.... chapter 5.5.1

Code:

case $(uname -m) in
    i?86)   ln -sfv ld-linux.so.2 $LFS/lib/ld-lsb.so.3
    ;;
    x86_64) ln -sfv ../lib/ld-linux-x86-64.so.2 $LFS/lib64
            ln -sfv ../lib/ld-linux-x86-64.so.2 $LFS/lib64/ld-lsb-x86-64.so.3
    ;;
esac

sym links not made properly

Okay! Now we're getting somewhere...however...
I've now run into this:

Code:

chroot: failed to run command ‘/usr/bin/env’: Too many levels of symbolic links

Thank you all,
I restart the process from the beginning and the issue has been resolved(It took me ~2-3 hours)

hendrickxm · 03-27-2021, 01:21 PM

You should have made those symlinks in chapter 5.5 and not afterwards.
Unfortunately this means redoing chapter 5.
