For dynamic configurations, meanings of symbols in the column Is Linking Needed are described in the following table.

Symbol	Description
+	The library requires direct linking to your project.
+ for early	The library should be linked to your project only if you are going to use it in the early binding mode.
-	The library should not be linked to your project if you are not going to use the class public interfaces directly in your application. Such a library uses the late binding mechanism and is linked to your application after loading.
no public	This option means that there is no public class interface in the library that can be directly used. Therefore it is not necessary to directly link the library to get access to its functionality in your applications.
+/- for public	The library can be used in late binding mode and in this case you should not link it to your project, but if you are going to use class interfaces from the library directly, you need to link it to your project.
