If you are using precompiled headers, try making 'ignore' static. boost/bind/placeholders.hpp has the same problem.
Bingo. The problem is that the web page I referenced in my previous post was suggesting replacing the tuple_basic_no_partial_spec.hpp file, where the "static" keyword was added for MSVC++. The fun is that this file is meant for compilers that do not support partial template specializations. MS VC++7.1 supports PTS, so it is the other file: tuple_basic.hpp that needs to be checked. I've made ignore static by doing this: namespace { #if (defined(BOOST_MSVC) && BOOST_MSVC <= 1310) || (defined(__DECCXX_VER) && __DECCXX_VER <= 60590031) static #endif detail::swallow_assign ignore; } instead of: namespace { detail::swallow_assign ignore; } Please note the 1310 value. It means MSVC++7.1. The other file that you suggested checking (placeholders.hpp) needed the value 1300 to be changed to 1310 (for MSVC++7.1 to be covered) so that all _1, _2, ... variables are made static. Now, after hacking these two files, all is OK. Thank you very much for your time, -- Maciej Sobczak : http://www.msobczak.com/ Programming : http://www.msobczak.com/prog/
