Hi All,

I'm using CCS 7.2.0.00013 on Windows 7 Professional and while debugging started to get an error : "Type 'Void' could not be resolved "
if I press on the error I am getting An error "Unhandled event loop excepption No more handles" and than "An SWT error has occurred. You are recommended to exit the workbench ....."

and this is part of the log file :

I attached screenshots of the errors.

How can I overcome this issue?

Before we get to the SWT error, let us first address the error seen in the Problems view: "Type 'Void' could not be resolved ".

This error is coming from the static code analyzer that comes built-in with Eclipse, and is not an error that should impact the build itself. You can confirm this by looking at the CCS build console. If there are no errors reported there then the project build is fine.

This page explains the code analysis errors and how to get around them. Importing the project into a new workspace should also resolve the errors. Once these errors are gone, the SWT and other exception should no longer be relevant.

Hope this helps.

Thanks for the answer!
Choosing the specific code analysis settings helped me to get around this issue, and as you wrote the other errors are no longer relevant now.

Best,
Ronen
