Re: [Boost-users] [Preprocessor] Relative Addresses in BOOST_PP_FILENAME_1

It is because BOOST_PP_FILENAME_1 expands in a Boost PP header file. In GCC a relative file name is relative only to the file in which it is included. Since it is a Boost PP header file that does the including, your relative header file will not be found.

In VC++ on Windows relative header files are relative to an entire chain of header files being included to that point from the source file on down, so a relative header file as you have above would be found.

Well, isn't this addressable in Boost PP?

No. Boost.PP can't change how the compiler searches for headers.

I mean, can Boost PP just not make its expansion compatible with this cross-compiler issue?

I ran into this same problem also and ended up just using a non-relative name of the form for all compilers as the easiest solution.

But, this requires my clients to copy my stuff under their local Boost directory, right?

No. That's just a specific example. You just need to make sure that the header is in the compiler's include path. In Christ, Steven Watanabe
