Re: [Doxygen-users] documentation of cuda fortran code

[Albert <alb...@gm...>]

Dear Tao,

Cuda Fortran has indeed some special extensions, that can be removed by
means of preprocessing, but one has to see to it that the FORTRAN code is
preprocessed. A FORTRAN file can be preprocessed when its extension is in
capitals. In the later case setting:
MACRO_EXPANSION        = YES
EXPAND_ONLY_PREDEF     = YES
PREDEFINED             = attributes(device)=

should be sufficient.
