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.

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
