[SOLVED] How To Gain Access For lfs User To Comply With 3rd Important Note in LFS Man., Sec. 5

gdawg · 05-18-2011, 10:21 AM

Hi - I've managed to install binutils and gcc but now I'm stuck at para. 5.6.1 - Installation of Linux API Headers - this is what is returned when I run the required commands:

Quote:

lfs@daisy:~$ make mrproper
make: *** No rule to make target `mrproper'. Stop.
lfs@daisy:~$ sudo make mrproper
[sudo] password for lfs:
make: *** No rule to make target `mrproper'. Stop.
lfs@daisy:~$ make headers_check
make: *** No rule to make target `headers_check'. Stop.
lfs@daisy:~$ sudo make headers_check
make: *** No rule to make target `headers_check'. Stop.
lfs@daisy:~$ make INSTALL_HDR_PATH=dest headers_install
make: *** No rule to make target `headers_install'. Stop.
lfs@daisy:~$ cp -rv dest/include/* /tools/include
cp: cannot stat `dest/include/*': No such file or directory

Is this what I should expect? Appreciate your help.

Hi,

Did you untar the linux kernel source (linux-2.6.37.tar.bz2) and enter the created directory before executing the commands?

Hope this helps.

gdawg · 05-18-2011, 11:09 AM

Hi - druuna, no I didn't go to the linux kernel source. I'll do that right now. Thank you.
Am I correct in deleting the un-tarred directories and build directories after they've been installed?

Kind regards,
Glen

Hi,

That's what I thought....

BTW: You're welcome

Yes delete the dirs You can rebuild them if you need to. Also later in book you have to rebuild them again so they will be fresh -build dirs to start on 2nd time.

Hi folks - I've managed to get to the "chroot" environment but I'm hung-up at section 6.5 of manual version 6.8 (Creating Directories). When I enter the commands I get the following results:

I'm confused about all of the "mkdir: cannot create directory ...:File exists" Is this to be expected?

druuna · 05-21-2011, 01:24 PM

Hi,

It looks like that LFS is not set to /mnt/lfs (assuming you followed the book) and you are not inside the chrooted environment:

Code:

[root@daisy ~]# 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 change root directory to : No such file or directory

Check if it is set:

Code:

echo $LFS

It should print /mnt/lfs

If you fixed that, got to chapter 6.2 and start from there with this command:

Code:

mkdir -v $LFS/{dev,proc,sys}

Hope this helps.

gdawg · 05-21-2011, 02:05 PM

Hi druuna - you are absolutely right. "echo $LFS" as root was blank. I went back to find how to set root up and did "export LFS=/mnt/lfs" as root and all is well. I'm sure I was told to check it but I forgot to and/or didn't remember how to reset it. Well, I'm certainly learning a lot. Thank you very much.

Best regards,

Glen

Ran into a bunch of failures while running "make -k check" at 6.16.GCC-4.5.2 of LFS manual. Everything was looking good until I ran this test. Here is a summary of the test:

Quote:

true

The downloaded files and patches are still in "sources". The test was run as

Quote:

root:/sources/gcc-build#

The manual states that some failures are expected but 12978 seems excessive. All help is appreciated. After the test I ran echo $LFS as root: and got nothing. I then re-ran "export LFS=/mnt/lfs". Was this correct?

Best regards,

Glen

Did u rerun gcc again,remove the gcc-build dir and gcc dir and untar again do check LFS is mounted, see what results you get

Some errors are expected, but you are correct in saying that 12000+ are too many.

There's not enough information posted to point you to a specific problem so I can only give you some general pointers:

- Did you remove the gcc and gcc build directory before starting? You need to start with a clean building environment. If, for whatever reason, you use a previously used building environment things can go wrong. Suggestion: remove the gcc-4.5.2 and gcc-build directory and start with untarring gcc-4.5.2.tar.bz2 and then follow the instructions in chapter 6.16.

- If the errors are still present: Please post some of them so we can have a look and maybe find the reason(s).

- Are you sure the previous packages build correctly?

Quote:

No it isn't. Once you enter the chrooted environment LFS isn't needed/used. The chroot command puts you in a jailed environment where /mnt/lfs/ becomes / (your "new" root directory).

Hope this helps.

Thanks for the replies spiky0011 and druuna. I'm totally lost now. Can't get back to where I was last night. I've been logging in as desktop user john, then "su - lfs" to get to "lfs" prompt. I went back to section 6.2 as "root @ daisy" and tried to repeat steps I took during last session but couldn't get past "I have no name" prompt. I can go to Dolphin, find "Root", open it locate "sources" and see the packages that I downloaded but can't seem to get there via console. When I "su -" and get prompt "root@daisy", "ls -l" doesn't show "Root" nor "sources". I don't know how to get back to where I was during previous session. Request guidance, please.

spiky0011 · 05-22-2011, 09:26 AM

Did you start at chapter 2.4 then go to 6.2

druuna · 05-22-2011, 09:32 AM

Hi,

The following steps need to be done to enter chapter 6:

Code:

- become root user
- check if LFS is set: echo $LFS
- check if LFS is mounted: df -h | grep $LFS
- If the above 2 are ok then:
mount -v --bind /dev $LFS/dev
mount -vt devpts devpts $LFS/dev/pts
mount -vt tmpfs shm $LFS/dev/shm
mount -vt proc proc $LFS/proc
mount -vt sysfs sysfs $LFS/sys
chroot "$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

You are now set to continue were you left of last time.

Hope this helps.
