I've just updated a project that was working under XCode 4 with boost 1.48 to XCode 5 and boost 1.55 (installed with MacPorts). Now I have a link error with Wave which wasn't the case before. This somehow baffles me as I thought everything was template based.
The wave libraries contain code for pre-instantiated templates only. If you instantiate the templates yourself you will not need to link with the libraries. Also, do the examples/the wave driver tool compile and link properly?
I am also linking with libboost-wave.mt.a but that doesn't solve the problem. The linker errors are, among 6 others:
Undefined symbols for architecture x86_64: "boost::wave::cpplexer::new_lexer_gen<__gnu_cxx::__normal_iterator<char*, std::string>, boost::wave::util::file_position<boost::wave::util::flex_string<char, std::char_traits<char>, std::allocator<char>, boost::wave::util::CowString<boost::wave::util::AllocatorStringStorage<cha r,

I've tried forcing std::string as the BOOST_WAVE_STRINGTYPE, but that just changes the signatures of the undefined symbols. I fail to see what has changed and I am completely stuck. I would have understood if I had a compiler error but this is a link error. Is this something to do with the standard C++ library? For my project, C++ dialect is C++98 and the standard library is libstdc++.
If you change BOOST_WAVE_STRINGTYPE it has to be done while compiling the wave libraries and while compiling your code. Regards Hartmut --------------- http://boost-spirit.com http://stellar.cct.lsu.edu
