Dear TONGARI,
Where I said <> I meant <something in compiler's include path>, that works fine, just as Edward and Steven said.
Well, my working directory is already in my compiler's include path. And, inside Header.hpp, the following line #define BOOST_PP_FILENAME1 <Header.hpp> fails to compiler in GCC 4.5.1 because GCC says it can't find Header.hpp. And, I am missing anything here? Maybe it's better that you tell me what you'd be writing instead of the line above if it would have been you...
If this is not a bug with a specific compiler, I hope at least it should be noted in Boost.PP's doc.
It's not. Both quote and angle brackets are mentioned to work in the specs: http://www.boost.org/doc/libs/1_45_0/libs/preprocessor/doc/ref/filename_x.ht... TIA, --Hossein
