Question

I’m using Doxygen to document my C++ code. All are well outputted in HTML format, except attributes/variables like below are not(not at all).

    /**
     * Flag to check whether the variable is once initialized or not
     */
     bool initialized_;

Any idea what could go wrong?

EDIT

initialized_ is a class member variable.

Answer 1

I’m not sure if this will solve your problem, since you have given very little information about the variable initialized_ (is it a global variable, is it part of a class etc.) but the doxygen documentation (see under the heading Documentation at other places) states that

To document a member of a C++ class, you must also document the class itself. The same holds for namespaces. To document a global C function, typedef, enum or preprocessor definition you must first document the file that contains it (usually this will be a header file, because that file contains the information that is exported to other source files).

Let’s repeat that, because it is often overlooked: to document global objects (functions, typedefs, enum, macros, etc), you must document the file in which they are defined. In other words, there must at least be a

/*! \file */ 

or a

/** @file */ 

line in this file.
