I need to generate documentation for a C++ project of mine (and soon perhaps also for additional ones). So far I've looked into doxygen, and even though it seems popular, I've had some issues with it (the details of which I won't go into here; some have been resolved). Since I'm not particularly attached to it - despite its apparent popularity - I want to consider some alternatives.
Now, 7 years ago there was a question on StackOverflow on exactly that:
but the answers are by now dated, so I'm reasking the same question, here and now.
Requirements:
- Libre
- Gratis
- Multiplatform, supporting at least Linux and Windows
- Flexible to a similar level as doxygen or more
- Actively maintained
- Non-negligible user base
