zstd tests failing on decompression only tests

fabulousUnicorn · 11-21-2021, 04:31 PM

I in chapter 8 of the lfs book, and am building zstd. When I run 'make check' the tests fail. Below is the output make gave me.

Code:

Usage : 
      zstd [args] [FILE(s)] [-o file] 

FILE    : a filename 
          with no FILE, or when FILE is - , read standard input
Arguments : 
 -#     : # compression level (1-19, default: 3) 
 -d     : decompression 
 -D DICT: use DICT as Dictionary for compression or decompression 
 -o file: result stored into `file` (only 1 output file) 
 -f     : disable input and output checks. Allows overwriting existing files,
          input from console, output to stdout, operating on links,
          block devices, etc.
--rm    : remove source file(s) after successful de/compression 
 -k     : preserve source file(s) (default) 
 -h/-H  : display help/long help and exit

The tests pass if I build it outside the chroot environment. I have no idea why this is happening. Any help would be appreciated

wiigelec · 11-21-2021, 06:36 PM

if it passes outside of chroot but fails within, i would say something in the chroot env is messed up.

my suggestion would be to clean the /mnt/lfs slate and start over again, paying close attention to details when building the packages.

are you copying and pasting the build commands or entering them by hand?

papadeltasierra · 11-29-2021, 07:37 AM

Did you manage to solve this? I'm hitting exactly the same problem, also inside a chroot.

wiigelec · 11-29-2021, 09:33 AM

can you provide additional details ie lfs version, hardware specs, host, how building ie manually entering commands, copy/paste commands, jhalfs etc...

papadeltasierra · 11-29-2021, 09:41 AM

Actually no need; I've just figured out what is going on. The `zstd` tests make use of a number of special files such as `/dev/null` and `dev/zero` and these are not present in the `chroot` by default. The solution is to use commands such as `mknod -m 666 /dev/zero c 1 5` (inside the chroot) to create these special files and then the tests run successfully.

The `1` and `5` are magic numbers but we can determine these by using `ls -lsap` outside the chroot e.g `ls -lsap /dev/zero` returns `0 crw-rw-rw- 1 root root 1, 5 Nov 29 08:35 /dev/zero` and you can see the magic `1` and `5` just before `Nov`.

the instructions for creating /dev/null are in the the book 7.3.1. Creating Initial Device Nodes:

https://www.linuxfromscratch.org/lfs...07/kernfs.html

i don’t seem to have ever had any issues around /dev/zero

hao · 08-31-2022, 11:25 AM

I also encountered this problem, version 11.1. after asking in irc channel, solved this by remount the kernel file systems as guided in https://www.linuxfromscratch.org/lfs...07/kernfs.html
