Hi Nymisha,
I understand that you are facing difficulty with MATLAB (version R2019A) when running simulation that is compatible with RT-LAB.The error message "Failed to load library ehsLibCpu" typically indicates an issue with finding or loading a specific library required for executing simulations, especially in real-time or hardware-in-the-loop (HIL) environments like RT-LAB. This problem can arise due to several reasons, including incorrect installation paths, missing dependencies, or compatibility issues.
Here are steps to troubleshoot and potentially resolve this issue:
- Verify Installation Paths: Check that the “ehsLibCpu” library exists in the installation directory of RT-LAB or the specified path where MATLAB expects to find it.
- Check Environment Variables: Ensure that the environment variables related to RT-LAB and its libraries are correctly set. This includes paths to any runtime libraries or binaries required by RT-LAB. Check and modify environment variables through the System Properties in Windows.
- Compatibility Check: Ensure the version of RT-LAB is compatible with MATLAB R2019a. If there is a compatibility issue, update RT-LAB, MATLAB, or both.
- MATLAB Path: Ensure that MATLAB path includes the directories containing the RT-LAB libraries. Add directories to MATLAB's path using the “addpath” function. Addpath- https://www.mathworks.com/help/matlab/ref/addpath.html?searchHighlight=addpath&s_tid=srchtitle_support_results_1_addpath
- Run as Administrator: Permission issues can prevent MATLAB or RT-LAB from accessing certain libraries. Try running MATLAB as an administrator to see if that resolves the issue.
Please refer to RT-LAB Documentation for troubleshooting on the issue-
Would require a bit of investigation to pinpoint the exact cause, but by systematically going through these steps, it should help to resolve it.
Hope it helps!
Best Regards,
Simar
