rsyslog v8 Error: 'doAction' undeclared in module-template.h

This error message indicates that the identifier 'doAction' is being used without being declared in the function at line 559 of the file 'module-template.h' in the rsyslog v8 source code.

To fix this error, you need to declare or define the 'doAction' identifier before using it in the function. Make sure that the declaration or definition is visible in the current scope.

If 'doAction' is a function, you may need to include the appropriate header file that contains its declaration. If 'doAction' is a variable, you may need to declare it before using it.

Check the surrounding code and make sure that 'doAction' is properly declared or defined before line 559 of 'module-template.h'.
