chroot: cannot run command `/tools/bin/env': No such file or directory

Basel · 09-05-2005, 08:24 AM

Hello,

Does anyone know why chroot is not able to run /tools/bin/env?

Code:

root@slackware:/# chroot /mnt/lfs_x86_64/ /tools/bin/env -i HOME=/root TERM="$TERM" PS1='\u:\w\$ ' PATH=/bin/:/usr/bin/:/sbin/:/usr/sbin/:/tools/bin/ /tools/bin/bash --login +h
chroot: cannot run command `/tools/bin/env': No such file or directory

Code:

hmm, did you set the $PATH????

Code:

export LFS=/path/to/lfs

I do not think there is a need to set the LFS for this command since I am using the complete path /mnt/lfs_x86_64

Code:

root@slackware:/home/basel# echo $PATH
/usr/local/sbin:/usr/local/bin:/sbin:/usr/sbin:/bin:/usr/bin
root@slackware:/home/basel# su - lfs
/dev/pts/2: Operation not permitted
lfs:~$ echo $PATH
/cross-tools/bin:/bin:/usr/bin
lfs:~$

Check your fstab, type mount and Ensure that this new partition is not mounted with permissions that are too restrictive
(such as the nosuid, nodev, or noatime options).
and/or noatime are set, the partition will need to be remounted.
Run the mount command without any parameters to see what options are set for the mounted LFS partition. If nosuid, nodev,

If so change the mount options for the LFS partition to <user,exec,dev,suid>

i had the same problem, found several threads on LQ and elsewhere about it - there seem to be too many ways to go wrong at this step. Though you may have solved your particular problem many months ago, an unending stream of head-scratching chroot wannabees will be discovering this and the other threads, so i'll describe my situation here.

I verified that /tools/bin/env did exist, ran it directly, and tried the same things others did. The problem turned out to be that in my LFS partition, mounted as /LFS, had a symbolic link where i had built my initial toolchain, /home/lfs/tools. I did this (not following the fine LFS book) so that i could play with other distros on the one partition, but keep my toolchain safe on another. Since a symbolic link was made in /, i figured the same would be okay in /LFS for access once i've chrooted. Not so! it just doesn't work. Solution: unmount the partition from /home, and remount it in /LFS/home (use mkdir /LFS/home if necessary) Then make a link: cd /LFS ; ln -s /home/lfs/tools tools - this link should work while chrooted to /LFS, but not earlier. (If you like, you could create another link in the host environment's /home, but then you should already have a /tools link for convenient access before the chrooting) Bottom line: Any symbolic links in /LFS to anything outside /LFS won't be any good while chrooted. Also, any partition mount points not in /LFS will become invisible after chroot.

I have the same problem as posted in the first one of this thread. What I found out was that the $PATH of root does not contain /tools/bin on echo

Quote:

# echo $PATH
/bin:/usr/bin:/sbin:/usr/sbin:/usr/X11R6/bin

So , i am getting the error of /tools/bin/env --> file not found.. Whereas it actually exists. Please tell me a solution ..
