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

As the cuda's ".cu" file is basically开发者_如何学运维 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.

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.

I suspect that this is your problem: http://www.doxygen.nl/manual/config.html#cfg_file_patterns

If the value of the INPUT tag contains directories, you can use the FILE_PATTERNS tag to specify one or more wildcard patterns (like *.cpp and *.h ) to filter out the source-files in the directories. If left blank the following patterns are tested: .c *.cc *.cxx *.cpp *.c++ *.d *.java *.ii *.ixx *.ipp *.i++ *.inl *.h *.hh .hxx *.hpp *.h++ *.idl *.odl *.cs *.php *.php3 *.inc *.m *.mm *.dox *.py .f90 *.f *.vhd *.vhdl
