Can't chroot

mrwall-e · 07-20-2010, 09:45 AM

I get the error /tools/bin/env: command not found, though I cd'ed into /tools/bin which contains a file "env". Why doesn't this work? The error is slightly different than others I've seen, so I hope I don't have to start over.

Your question seems to be lacking a little context but for some basic responses .. is the file executable ? .. also it probably won't be in your PATH so you'll need to run it as './env' or '/tools/bin/env'

What is /tools/bin/env linked to?

Code:

ldd /tools/bin/env

If it's linked to anything that isn't in /tools then it won't work in chroot.

thanks so much for replying...

sorry, but by making it executable, you mean chmod 755, correct? here is the page in the lfs book: http://www.linuxfromscratch.org/lfs/...06/chroot.html and what exactly did you mean by "won't be in your PATH"? sorry, just not sure what you mean...

Oh and btw I'm really sorry about a horrible first post, I was in a rush when I posted it. Thanks so much for your patience.

This command returns: /usr/bin/ldd: line 226: /tools/bin/env: No such file or directory

Hi,

As which user are you doing this? Chapter 5 needs to be done as user lfs and chapter 6 as user root.

What's the output of the following commands:

ls -l /tools/bin/{e,ho}*
echo $LFS

The env command is part of the coreutils package (5.17. Coreutils-8.4). If anything went wrong in that chapter, more commands are not correct (try /tools/bin/hostname and /tools/bin/echo "X" and see if those commands work).

Hope this helps.

Thanks so much for replying, I did all of Chapter 5 as user "lfs", created at the beginning, and all of Chapter 6 as root. Here is the output of those commands:

-rwxr-xr-x 1 root root 18708 Jul 20 10:40 /tools/bin/echo
-rwxr-xr-x 1 root root 72140 Jul 20 10:40 /tools/bin/egrep
-rwxr-xr-x 1 root root 18056 Jul 20 10:40 /tools/bin/env
-rwxr-xr-x 1 root root 20512 Jul 20 10:40 /tools/bin/expand
-rwxr-xr-x 1 root root 132312 Jul 20 10:40 /tools/bin/expect
-rwxr-xr-x 1 root root 27316 Jul 20 10:40 /tools/bin/expr
-rwxr-xr-x 1 root root 16416 Jul 20 10:40 /tools/bin/hostid
-rwxr-xr-x 1 root root 16968 Jul 20 10:40 /tools/bin/hostname

Neither of those last two commands work.

Hi,

If all three commands you tried (env, hostname and echo) failed then something must have gone wrong in chapter 5, probably the coreutils chapter.

You are still in the early stage of chapter 6 so a re-visit to chapter 5 must still be possible. Redo all the steps in chapter 5.17. Coreutils-8.4 (mind you: as user lfs!!).

I don't think any of the later packages need to be redone (the hostname part for perl is only for testing).

Hopefully this solves your problem.
