Two examples of shared library problems, is this a 18.04 issue?

Question

I've just tried to run this program and have had library problems. I have the right libraries, but the program is looking in the wrong place? Is there a fix?

EDIT: I should say that I installed this via a DEB file from here:

$ Todour 
 Todour: error while loading shared libraries: libxcb-keysyms.so.1: cannot open shared object file: No such file or directory


$ apt-file search libxcb-keysyms.so.1
 libxcb-keysyms1: /usr/lib/x86_64-linux-gnu/libxcb-keysyms.so.1
 libxcb-keysyms1: /usr/lib/x86_64-linux-gnu/libxcb-keysyms.so.1.0.0

As per request:

 $ ldd Todour | grep not
  ldd: ./Todour: No such file or directory

AND

 $ file Todour
 Todour: cannot open `Todour' (No such file or directory)

EDIT: I also tried this:

  $ export LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/:$LD_LIBRARY_PATH
  $ Todour 
  Todour: error while loading shared libraries: libxcb-keysyms.so.1: wrong ELF class: ELFCLASS64

I've also added the i386 dependancies as per this command:

 sudo apt install libxcb-keysyms1:i386

Still getting the ELF class response.

Answer 1

The issue about dependencies was created on GitHub project page, now it is fixed.

The binary is 32-bit, so we need to enable 32-bit support

sudo dpkg --add-architecture i386
sudo apt update

then download the package

cd ~/Downloads
wget https://nerdur.com/Todour-v2.17.deb

and install it:

sudo apt install ./Todour-v2.17.deb

and enjoy:
