ERROR: Environment variable LD_LIBRARY_PATH not defined / Linux

[chaytheeditors]

I've just tried installing the latest version (m95, 2.25) on Zorin OS (Based on Ubuntu 20.04) and get the following error when trying to launch:

ERROR: Environment variable LD_LIBRARY_PATH not defined

Please set environment variable LD_LIBRARY_PATH to the path to the directory 'obs-plugins'

Usually directory 'obs-plugins' is to be found at /usr/lib

To set environment variable LD_LIBRARY_PATH to /usr/lib/obs-plugins, use the following command:
export LD_LIBRARY_PATH=/usr/lib/obs-plugins

I tried the command in terminal, but it doesn't recognise the command 'export'.

I was able to successfully install and run vanilla OBS, so doesn't seem to be an OBS / Zorin thing.

I also tried installing the previous version (m95, 2.24) but got the same result.

Edit: Just tried on Ubuntu 20.04 and got the same error.

Command line export LD_LIBRARY_PATH=/usr/lib/obs-plugins is valid assuming your are using bash shell.
Depending on the shell you are using, you should modify the command line to add directory /usr/lib/obs-plugins to your environment variable LD_LIBRARY_PATH.

I have the same problem. I installed obs-webrtc-x64-27.1.3-m95-2.25-2004.deb via Eddy on PopOS. Then I start the app via the Applications popup and the message appears.

I'm sorta new to Linux but I assume that putting export LD_LIBRARY_PATH=/usr/lib/obs-plugins in the shell only works in the shell.

Can I launch OBS from the shell somehow? I can't figure out where the binary was installed.

Thank you!

Yeah, I'm used to just launching this from the app icon (and usually on Windows or Mac OS). Is there a particular file that needs editing? sudo bash seems to launch into bash from Zorin terminal and I get no errors using export LD_LIBRARY_PATH=/usr/lib/obs-plugins , but then I still get the error when trying to launch.

When you run command export LD_LIBRARY_PATH=/usr/lib/obs-plugins inside a bash shell, it sets the environment variable LD_LIBRARY_PATH for that shell only.
If you want the environment variable LD_LIBRARY_PATH to be set for your whole session, you need to set it in the local configuration file of your login shell.

• What is my login shell?
  On a terminal, type:
  echo $SHELL
• What is my local configuration file for my login shell?
  It depends on your login shell.
  For bash, local configuration files are ~/.bash_profile, ~/.bash_login, ~/.profile and ~/.bashrc
  As your login shell is not bash, your local shell configuration file is not the same as for bash.
  Make a search for your login shell to find what is its local configuration file and what is the syntax to set the environment variable LD_LIBRARY_PATH for that shell.
  Add appropriate command lines for your login shell in your shell local configuration file to set LD_LIBRARY_PATH, then logout, and log in again. Open a shell to check that environment variable LD_LIBRARY_PATH has been set during login:
  echo $LD_LIBRARY_PATH

To launch OBS from the shell where you set LD_LIBRARY_PATH, simply type obs
Alternatively, you may type the whole path to the binary: /usr/bin/obs

Is this something that is likely to be fixed in a future release? As mentioned, expected behaviour would able to just launch this program from the dock/app list. There are also others in my company that will need to launch this and this will be far too much effort.
