Does doxygen predefine any macros?

Apart from the PREDEFINED configuration option, where I could always put DOXYGEN=1, does doxygen predefine any preprocessor macros prior to reading C++ files?

My train of thought is that GCC predefines macros such as __GNUC__开发者_StackOverflow社区, and MSC predefines macros such as _MSC_VER. Does doxygen predefine macros at all, such as _DOXYGEN_VER?

I don't want to use the PREDEFINED configuration option at all.

No, Doxygen does not predefine any self-identifying tokens.

If you don't want to litter your code with preprocessor #ifdef _DOXYGEN_VER / #endif blocks you can use the \cond command. The \cond command is an easier way to define sections that may be conditionally included/excluded similar to what you used to have to do with the C preprocessor tokens.
