* You can also add [`Security` dependencies with `scopes`](../advanced/security/oauth2-scopes.md){.internal-link target=_blank}.

!!! tip
    Having `dependencies` in the `APIRouter` can be used, for example, to require authentication for a whole group of *path operations*. Even if the dependencies are not added individually to each one of them.

present to create such a binary.

Most builds both compile source code and invoke the linker to create a
binary. When cgo is involved, the compile step already requires gcc, so
it is not problematic for the link step to require gcc too.

An important exception is builds using a pre-compiled copy of the
standard library. In particular, package net uses cgo on most systems,

implementation class. Finally, some Log implementations (such as the one for Log4J) require an external configuration file for the entire logging environment. This file should be prepared in a manner that is specific to the actual logging technology being used. Using the Logging Package APIs Use of the Logging Package APIs, from the perspective of an application component, consists of the following steps: Acquire a reference to an instance of org.apache.commons.logging.Log, by calling the factory...
