[SOLVED] Linux from Scratch 5.7.2 Toolchain sanity check

Rafnex · 04-28-2016, 06:38 AM

I started the Project "Linux from Scratch" some time ago. First I started with Ubuntu 15.10 64bit and did everything according to the PDF-File. By the Check in paragraph 5.7.2, it didn't worked. Afterwards I started all over again, with CentOS 7.2 but it works neither.In both attempts i got no Errors while compiling and installing the previous packages.

Input:

Code:

echo 'int main(){}' > dummy.c
$LFS_TGT-gcc dummy.c

Output:

Code:

/mnt/lfs/tools/bin/../lib/gcc/x86_64-lfs-linux-gnu/5.3.0/../../../../x86_64-lfs-linux-gnu/bin/ld: cannot find crt1.o: No such file or directory
/mnt/lfs/tools/bin/../lib/gcc/x86_64-lfs-linux-gnu/5.3.0/../../../../x86_64-lfs-linux-gnu/bin/ld: cannot find crti.o: No such file or directory
/mnt/lfs/tools/bin/../lib/gcc/x86_64-lfs-linux-gnu/5.3.0/../../../../x86_64-lfs-linux-gnu/bin/ld: cannot find -lc
/mnt/lfs/tools/bin/../lib/gcc/x86_64-lfs-linux-gnu/5.3.0/../../../../x86_64-lfs-linux-gnu/bin/ld: cannot find crtn.o: No such file or directory
collect2: error: ld returned 1 exit status

Input:

Code:

readelf -l a.out | grep ': /tools'

Output:

Code:

readelf: Error: 'a.out': No such file

I found no solution that worked in StackOverFlow or different platforms.

Here my Output of the version-check.sh:

Thanks for your help!

You've made errors somewhere. Chapter 5 isn't too bad.

Delete, and start over. I would use the html book - easier for copy 'n' paste. You haven't much ground to catch up. You need chapter 5 in good order going into chapter 6.

CentOS is Red Hat based, and RHEL is a known problem distribution for building LFS.

We don't know why, but it's possibly something they use like a patch and it causes everything to go screwy.

If it's not too much trouble, Slackware might be useful for you to get LFS built. AlienBOB has a few Live media disk images available and they can be used to get Chapter 5 completed before you move into Chapter 6. If you ever use a Live disk to build LFS, you have to build Chapter 5 in one session or it will mess up the permissions.

Salix Live is a good alternative for host. I've been using it to build my LFS systems. It is largely (if not entirely) compatible with Slackware, and meets all of the build requirements for LFS out of the box. Get the XFCE version and load it onto your USB stick

Hi together!

Solved it.

I started again and unziped the packages with "tar -xf" instead of "tar -jxvf".

And it worked!

Thanks for your help!

Because of this post, I also re-worked the steps using "tar xf" rather than "tar jxvf". This seems to have fixed the issue for me too. CentOS 7.

Thank you, Rafnex.
