问题
I have made a Doxygen documentation, which itself references another documentation using the tag-file mechanism. But inside its mainpage I now would like to link to the mainpage of the external documentation. Of course, I can always specify the file directly:
... uses [OtherDoc](../../../OtherProject/doc/html/index.html) for ...
even more so since the projects are located relative to each other. But nevertheless I would like Doxygen to automate this process, since it needs to know the location of the external documentation, anyway.
So is there a way to somehow symbolically reference the external documentation's mainpage, something along the lines of:
[OtherDoc](\ref OtherProject::mainpage)
or
[OtherDoc](#OtherProject::mainpage)
回答1:
There is a trick to do this. Say you have projects A and B, then in the main page of project A you could put an @anchor command like so:
/** @mainpage
* @anchor project_a
*/
And in the documentation of project b you can then simply use
[OtherDoc](\ref project_a)
Note that anchors have to be globally unique, so you need to carefully choose them!
