Editing GCC Toolset Activation (section)

== Demonstration of Switching GCC Versions ==

This section demonstrates how to switch between different GCC versions and verify the active version. The username in the examples has been changed to 'dvosler' as requested.

This output shows the default GCC version, and then the versions after enabling GCC toolsets 9, 10, and 11, respectively. The examples end with exiting back to the session with the default GCC version.
