# Filtering errors

The Error Parsers page of the Properties window lists a set of filters that detect error patterns in the build output log.

If an error or warning is detected, an icon appears on the file in the Tasks view. If the file is not found, the icon appears on the project.

You can define the properties on a per project basis in the New Project wizard, in the C/C++ Projects view or in the Navigator view. You can also define project properties in the Preferences window for future standard make projects.

To select error parsers:

1. Do one of the following:

- To set properties for future Standard Make projects, click Window > Preferences . ExpandC/C++, and click New Make Projects.
- In the C/C++ Projects view, right-click a standard make project, and select Properties. Select C/C++ Make Project from the list.

2. Click the Error Parsers tab.
3. In the Error parsers list, select error parsers.
4. Click OK.
