Error while editing the library reference in editor

This section quotes the errors that might occur when editing a →library reference within the editor.
However, it is possible that errors/warnings occur for the library reference as when entering the ST-code. See "Errors and warnings in ST" for this message and its appropriate solution.

Modifications of the library reference are not needed by default.

  • Usually, you do not edit the library reference of a project. Reason: The content of the library reference is automatically adapted, if you are installing or removing libraries within the properties of the project.

  • Only if you need to store a library outside the library providers, you have to adapt the content of the library reference. This requires some knowledge of the syntax of the library reference.

See "Using the library reference and its syntax" for details on the syntax of the library reference.

The referenced library "name" cannot be installed. If you do not fix this error, the editor features for ST/FBD are not provided with its usual scope or not at all.
Additional information: A library that cannot be installed is influencing the editor features within the project, even if this library (actually its library elements) are not needed in the project at all. For example, it is possible that the content assist within the editor does no provide library elements at all – even no elements of the standard libraries, such as ADD or AND .
Solution 1: Delete the line with the specified library from the library reference. Alternative: Remove it within the properties of the project as specified under "Deleting already deployed libraries".
Solution 2: Make sure that the named library has been deployed to a library provider and the library cache. If this is not the case, deploy the specified library. Details: See "Deploying the library".

"name" is an invalid or an unsupported path name.
Solution: Enter a different path.

The specification "SOURCE" must not be used without the specification "PROVIDER". or
The specification "PROVIDER" must not be used without the specification "SOURCE".
Solution: Use both specifications as described under "Using the library reference and its syntax".
