That one test failed on all the machines where I ran the testsuite.
Seems to be a new failure since 2.34.1 (my previous builds).

If you have nothing better to do, I guess you could look at this
when the completed system is running, and see if a fresh build +
test (not an install!) is also affected.  From that spinics thread,
ncursesw was picked up - on LFS that would be correct.  But in the
great scheme of things I would not worry about this unless the
details of the util-linux testsuite are interesting to you.

Correction: "running these tests" (for util-linux).

[lfs-support] Util-linux test fails for column: invalid multibyte

[Bud Rozwood]

Hi,

I'm trying to run the test suite as a non-root user for Util-linux for the
LFS version 9.1 but I keep getting 1 test failure for "column: invalid
multibyte" test.

I'm on an x86_64 bit machine, using pacman package manager. Here are the

, but that was
for an older version of util-linux. So I thought it might of been my
locales but I don't think so:

I've compared it with the LFS test-logs

on an i7 processor (similar to mine) but they got them to all pass. Should
I worry about this?

 ^^

(section 5.15.1, at the bottom -
ln -s libncursesw.so /tools/lib/libncurses.so)

At this point in the build, libncursesw.so can only be in
/tools/lib.  You showed output from ls -l for /lib, with it not
present, but that is correct until a little later in chapter 6.

Hi Steve,

it seems a very uncommon problem, so some questions just in case:

Do you have a CD in the drive when you try to shutdown ?

Is the CD using an old or obscure driver (I'm thinking of old PATA
drives, I guess anything older than that is unlikely to still be
usable.  Hmm, that prompts me to ask if the CD drive is working with
this kernel ?

Recent kernels have seen a lot of overhauls in the kernel
infrastructure. perhaps your .config for versions after 4.20.12 has
lost something it needs for the CDROM.  Seems unlikely, since it
shows up, but testing that it works will dispel that suggestion.

For finding which commit caused a problem, you really need to run
git bisect.  I hope you are aware that the stable kernels maintained
by Greg KH use a different git tree from Linus' upstream, and that
while in Linus' tree there is a progression from 4.20.0 to 5.6.0, in
Greg's stable trees the progressions are 4.20.0 to 4.20.last, 5.0.0
to 5.0.last, etc.

Picking random versions can help identify where a problem occurred,
but it needs a plan.  I'll suggest you try 5.6.latest first (5.6.3
at the moment), just in case.  Assuming that is still broken, try
5.6.0 itself to confirm the breakage.  Then try 4.20.0 to confirm
that was ok (we know 4.20.12 was ok, but that is not in

Hi there,

This is my 3rd attempt at getting through LFS for the first time using (Debian 
10).  It was a fresh install when I made my second attempt.  Then hit this 
error and redid chapters 4, 5 and 6 before failing at the same place.  While 
I'd typed all commands on my 2nd try (for better absorption), I copied and 
pasted all commands this time (3rd) around

On section 6.25 - GCC, I get the following error on the make check:

su nobody -s /bin/bash -c "PATH=$PATH make -k check" =>
su: Cannot drop the controlling terminal

commands I've run based on different threads I've found usually referring to 
different sections and/or previous versions of the book (as root, within chroot)
ls -l /tools/bin/bash   =>   -rwxr-xr-x

ls -l /dev/pts =>  c- 1 root root 5, 2 Apr 12 10:22 ptmx

i had also checked some other permissions which are mentioned in this thread, 
when I was trying to wrap my head around the controlling terminal: 
https://www.linuxquestions.org/questions/linux-from-scratch-13/su-cannot-drop-the-controlling-terminal-6-25-gcc-4175671731/

Admittedly, I still don't really understand what is going on.

Any help or suggestions would be very much appreciated!

Thank you, take care,
Al


Hi Al,

dump question, but are the virtual filesystems mounted as described in
section 6.2 ?


Indeed.  It looks like the virtual file systems are not correct.  From 
the *host*, run:


  findmnt

You should have:

TARGET SOURCE FSTYPE   OPTIONS
├─/mnt/lfs /dev/sda6  ext4 rw,noatime
│ ├─/mnt/lfs/dev   devtmpfs   devtmpfs 
rw,relatime,size=8147408k,nr_inodes=2036852,mode=755
│ │ └─/mnt/lfs/dev/pts devpts devpts 
rw,relatime,gid=5,mode=620,ptmxmode=000

│ ├─/mnt/lfs/proc  proc   proc rw,relatime
│ ├─/mnt/lfs/sys   sysfs  sysfsrw,relatime
│ ├─/mnt/lfs/run   runtmpfsrw,relatime

Some of the options for /mnt/lfs/dev and /mnt/lfs/dev/pts may differ a 
bit, but that's OK.


You should also have:

$ ls -l $LFS/var/run
lrwxrwxrwx 1 root root 4 Mar 31 13:53 /mnt/lfs/var/run -> /run

$ ls -l $LFS/dev/shm
lrwxrwxrwx 1 root root 8 Mar  4 15:00 /mnt/lfs/dev/shm -> /run/shm

Hi Al,

dump question, but are the virtual filesystems mounted as described in

I digged up my mail archive for a while.  Douglas said he'd been using Debian 10
as the host to build LFS.  So I think it's not a bug of Debian or LFS book.

All these seem OK.

Which version of LFS book are you using?  And what is the output of "version-
check.sh" in sect. 2.2.?
