Step 3.1: Use Placeholder References
For referencing common libraries, use placeholder references.
Use library placeholders to make a project compatible for interchangeable target devices or for different compiler versions. When adding a library to a project, consider using a placeholder instead of a specific library version. Then the required version of a library is referenced, according to the valid definition of the placeholder resolution.
For the final, effective resolution definition, the following locations are regarded in ascending order. Item 3 has top priority:
1.The library profile, by default provided with the programming system installation, defining the resolution of a placeholder depending on the compiler version. For details, refer to the Library Profiles description.
2.The device description of the set target, defining the device-specific placeholder resolution (if no device is available, the default resolution specified for the placeholder is performed).
3.The Placeholders dialog box that is accessible from the Library Manager, where you can modify the resolution of the placeholder specifically for the project.
NOTE: This is the final and effective resolution. Modify it only after careful consideration.
