Linux: RHEL 9.1: libjpeg.so.8: cannot open shared object file (SOLVED)

[fastrizwaan]

Does not work in rhel 9.1 / rocky 9.1

/opt/gpt4all\ 0.1.0/bin/chat 
/opt/gpt4all 0.1.0/bin/chat: error while loading shared libraries: libjpeg.so.8: cannot open shared object file: No such file or directory

Kindly include all the dependencies in /opt/gpt4all\ 0.1.0/lib/ for it to work.

[root@localhost jpeg-8d]# ldd /opt/gpt4all\ 0.1.0/bin/chat |grep -i not

Can confirm that it also fails with the same error on the latest linux mint. Just installed mint, just installed this. I get the error above as well.

On Linux Mint I got a similar issue, I got the following error: ./chat: error while loading shared libraries: libxcb-cursor.so.0: cannot open shared object file: No such file or directory

Then I installed libxcb-cursor by: sudo apt install libxcb-cursor0

Then running the binary again, I got different errors:

I've copied required files from ubuntu 22.04 livecd and https://packages.ubuntu.com/jammy/libxcb1

extract the tar archive, now it works in rhel 9.1 https://github.com/fastrizwaan/gpt4all-libs/releases/tag/0.1.0

fixed for me with https://github.com/nomic-ai/gpt4all-chat/issues/3

[Solved] With Fedora 37, it was also not able to find libjpeg.so.8, but I was able to work around it:

$ locate libjpeg.so.8

Expanding on PenelopFudd's process of locating libjpeg.so.8 and copying it over, while making sure it's actually a ELF64 bit file.

#!/bin/bash

## Find LibJpeg ##
# Set the expected architecture for the libjpeg.so.8 file
EXPECTED_ARCH="ELF 64-bit LSB shared object"

# Use the locate command to find candidate files
candidates=$(locate libjpeg.so.8)

# We want to copy the found lib file to here
destination=/opt/gpt4all/lib/libjpeg.so.8

# Loop through each candidate file
for file_path in $candidates; do
  # Check the architecture of the file
  file_output=$(file "$file_path")
  if [[ "$file_output" == *"$EXPECTED_ARCH"* ]]; then
    # Copy the file to /opt/gpt4all 0.1.0/lib/
    echo "found 64bit lib file in $file_path"
    sudo cp "$file_path" "$destination"
    break
  fi
done

I was actually kind of distressed that typing yum provides '*/libjpeg.so.8' didn't find anything:

Error: No matches found. If searching for a file, try specifying the full path or using a wildcard prefix ("*/") at the beginning.

It seems that's a normal problem encountered when running executables built on other systems.

Duplicate and fixed.
