For Linux installations, a script called check_dependencies.sh is provided in the DSim installation directory in ~/metrics-ca/dsim/<version>/. We recommend you run the script as it will make suggestions about any packages that need installing. You will need to run these commands with sudo if you are not the root user.

For example, open a shell terminal and run:

%> cd ~/metrics-ca/dsim/<version>
%> ./check_dependencies.sh

The script will make suggestions like the following as needed:

Please install the missing packages with the following commands.
You will be required to respond to questions or you can add '-y'
to the end of each command to answer yes to all questions.
(Note: these must be run as the root user or prefixed with sudo)
    apt update
    apt install binutils

Again, you'll need sudo or be the root user. If you are not the root user, then the you must be a user with sudo permission and then you can run:

%> sudo apt update
%> sudo apt install binutils

If you are using an unsupported OS, DSim Cloud may likely work. However, we are not testing internally for it.

Operating Systems

* An issue has been found with Ubuntu 22.04 whereby the DSim Cloud CLI will not operate after installation. Running the mdc --version command will return the following error:

%> mdc --version  
No usable version of libssl was found  
Aborted (core dumped)

To install libssl onto Ubuntu, please perform the following steps, which should clear the issue.

%> echo"deb http://security.ubuntu.com/ubuntu impish-security main" | sudo tee /etc/apt/sources.list.d/impish-security.list
%> sudo apt-get update
