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

[basel_mahdi545@…]

Linux From Scratch - Version 7.0-cross-lfs-20050902-x86_64-Multilib Host Distribution - Slackware 10.1 with kernel-2.6.13 Section - 8.4. Entering the Chroot Environment Processor - AMD64 3000+

root@slackware:/home/basel# chroot "$LFS" /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

I even tried to add /mnt/lfs_x86_64 to PATH but I got another error:

root@slackware:/home/basel# echo $PATH /usr/local/sbin:/usr/local/bin:/sbin:/usr/sbin:/bin:/usr/bin root@slackware:/home/basel# export PATH=/mnt/lfs_x86_64/tools/bin/:$PATH root@slackware:/home/basel# chroot "$LFS" /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

bash: /mnt/lfs_x86_64/tools/bin/chroot: cannot execute binary file

I was not able to execute any comman after I added /mnt/lfs_x86_64/tools/bin to PATH:

root@slackware:/home/basel# ls -l /mnt/lfs_x86_64/tools/bin/chroot bash: /mnt/lfs_x86_64/tools/bin/ls: cannot execute binary file

I took a look at the mailing list and found the following thread: ​http://archives.linuxfromscratch.org/mail-archives/lfs-support/2005-July/027736.html Jens Olav suggests that there might be some problems with sed/perl/whatever adjustments to the spec files. How do I know if it was my fault or the commands did not execute as expected. Here is the output from my machine: lfs:~$ ldd /tools/bin/bash

not a dynamic executable

It would be nice if there is a way to verify the output of these commands.

Here is what I did initially after a reboot(this happened even before the reboot):

basel@slackware:~$ su Password: root@slackware:/home/basel# export LFS=/mnt/lfs_x86_64/ root@slackware:/home/basel# mount /dev/sda2 /mnt/lfs_x86_64/ root@slackware:/home/basel# ls -l /mnt/lfs_x86_64/ total 4 drwxr-xr-x 2 root root 48 2005-09-05 15:28 proc drwxr-xr-x 3 lfs lfs 4152 2005-09-05 15:26 sources drwxr-xr-x 2 root root 48 2005-09-05 15:28 sys drwxr-xr-x 14 lfs lfs 352 2005-09-05 14:42 tools root@slackware:/home/basel# mount -t proc proc $LFS/proc root@slackware:/home/basel# mount -t sysfs sysfs $LFS/sys root@slackware:/home/basel# mount -f -t tmpfs tmpfs $LFS/dev root@slackware:/home/basel# mount -f -t tmpfs tmpfs $LFS/dev/shm root@slackware:/home/basel# mount -f -t devpts -o gid=4,mode=620 devpts $LFS/dev/pts root@slackware:/home/basel# chroot "$LFS" /tools/bin/env -i \

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

However, "ls -l" shows that "env" exists:

Please use lfs-support for support queries like this in the future. Your problem has been answered in the mailing lists many times, and is therefore now available in the FAQ (Frequently Asked Questions) at ​http://www.linuxfromscratch.org/lfs/faq.html#any-no-such-file. Basically, take a look at the gcc's specs file and if it still contains references to /tools then the sed/perl/patch adjustments didn't work correctly.
