Cannot use zstd even though already put into both computer and remarkable.

The following is my error code.
Somehow the shell cannot find zstd in the remarkable.
sh: /home/root/zstd: No such file or directory
I tried both dash and bash.
/usr/bin/zstd

If I log in the remarkable ssh and try to type it, it say no such file or directory, while zstd is actually there.
remarkable: ~/ /home/root/zstd
-sh: /home/root/zstd: No such file or directory
remarkable: ~/ ls zstd
zstd
Strange. @huijunchen9260, what is your home directory on your remarkable? e.g. what does pwd produce?
I have pushed a possible fix. Could you look if it fixes the problem?
I'm experiencing the same issue:
remarkable: ~/ pwd
/home/root
remarkable: ~/ ls zstd
zstd
remarkable: ~/ ./zstd
-sh: ./zstd: No such file or directory
remarkable: ~/ /home/root/zstd
-sh: /home/root/zstd: No such file or directory
sh doesn't seem to find the binary if I try to execute it.
I tried the most recent version of the script (with ~/zstd) but as you can see, the path doesn't seem to be the problem
EDIT:
Solved it: The path of ld is different on the rM. I just created a symlink.
remarkable: ~/ file zstd
zstd: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /opt/lib/ld-linux.so.3, for GNU/Linux 3.2.0, stripped
remarkable: ~/ ln -s "/lib/ld-linux-armhf.so.3" /opt/lib/ld-linux.so.3
ln: /opt/lib/ld-linux.so.3: No such file or directory
remarkable: ~/ mkdir -p /opt/lib
remarkable: ~/ ln -s "/lib/ld-linux-armhf.so.3" /opt/lib/ld-linux.so.3
remarkable: ~/ ./zstd
Incorrect parameters
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 file: use `file` as Dictionary
-o file: result stored into `file` (only if 1 input file)
-f : overwrite output without prompting and (de)compress links
--rm : remove source file(s) after successful de/compression
-k : preserve source file(s) (default)
-h/-H : display help/long help and exit
Ah, that is probably caused by entware. I gues I could try compiling a statically linked binary of zstd.
Thanks for troubleshooting!
I just had a look at the entware repo. It puts everything into /opt which is linked to ~/.entware but /opt doesn't exist on the rM and is created during the installation of entware.
I think a statically linked binary would be the best solution for users without entware.
You're welcome. Awesome project, by the way!
After I tried the update version, it works!
Thank you for such an awesome project!
I have switched to lz4 in my latest commit (9f6ba5d), which makes it a lot easier to install on the reMarkable (and as bonus: it's slightly faster!).
@rien, maybe you'll find this interesting: https://facebook.github.io/zstd/#small-data
With train data, zstd can beat lz4's speed. And it already has more throughput, so maybe better framerate. Although it's good to refrain ourselves from reimplementing a codec job using zstd and just stick to the basics.
Cool project, btw.
