Linux From Scratch Perl problems

Hi,

I'm building the latest version of LFS (6.8) on a Virtualbox VM and I'm running into a problem where Perl works before I chroot in Chapter 6, but when I chroot to build my kernel APIs I'm getting /usr/bin/perl No such File or directory.

When I cd to the build directory (/tools), I still have the same problem. When I exit the chroot environment, perl works!

Have any of you experienced this? Is there something that I'm doing wrong?

Hi,

It sounds like you didn't install perl or didn't install it correctly when doing chapter 5.

The working perl (the one outside the chrooted environment) is the one that is provided by your host. Once you chroot as mentioned in chapter 6.4 you make use of what has been build in chapter 5.

First make sure you used the correct chroot command, it could be that your PATH setting isn't correct. Then check if perl is installed correctly (you might want to redo chapter 5.28).

Hope this helps.

It sounds like you've made a mistake somewhere in chapter 5 and compiled perl or something perl relies on so that they are liked to files on your host system that are not available in chroot. The way to find out is to run

Code:

ldd /tools/bin/perl

If it lists libraries in /lib or /usr/lib then that is where the problem lies. When you first chroot /lib and /usr/lib are empty. All the things in /tools should only link to things in /tools/lib. If you've made this mistake with perl you may well have done the same thing with everything else.
