Is there a way to document cuda's ".cu" file use doxygen

Question

As the cuda's ".cu" file is basically c, Is there a way we can use doxygen to generate documentation for ".cu" files? I noticed that NVIDIA use doxygen to generate cuda's docuementation. However when I use doxygen, the ".cu" files are ignored.

Answer 1

In case anyone else is coming along and reading this with the same problem, what you need to do is this:

1. Add *.cu to FILE_PATTERNS.

2. Add cu=c++ EXTENSION_MAPPING.

You can find documentation for both options here.

If you're using the Windows Doxygen GUI frontend, FILE_PATTERNS is on the Input page and EXTENSION_MAPPING is on the Project page.
