LD_LIBRARY_PATH

The default LD_LIBRARY_PATH environment variable is incorrectly set in the Ubuntu VM. As a result, GNU Radio might not be able to find the compiled OOT modules. Please do the following to correct this issue.

Open BASH configuration file in VS Code.

$ code ~/.bashrc

Update the existing line setting LD_LIBRARY_PATH as follows:

export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/usr/local/lib/x86_64-linux-gnu/

Update the environment variables for your current terminal.

$ source ~/.bashrc

Make sure Linux is aware of any new OOT libraries:

$ sudo ldconfig

New terminal instances should will have the correct path, but you may need to perform this update every time you start the Ubuntu VM.
