(I'm not sure this is strictly related to Multi-Index in fact)

Hi. If I

#include #include #include #include #include #include

I get

boost\detail\allocator_utilities.hpp(182) : warning C4100: 'p' : unreferenced formal parameter

I've checked this out, the spurious warning seems to happen when the elements of the multi_index_container (which are destroyed via boost::detail::allocator::destroy) are classes with a trivial destructor.

If I try to suppress it with: [...] I get even more warnings (way more).

It' weird, because I tried it myself and the warning indeed disappears (MSVC 8.0): #define SUPPRESS_C4100 #ifdef SUPPRESS_C4100 #if defined(_WIN32) && defined( _MSC_VER ) #pragma warning(push) #pragma warning(disable : 4100) // unreferenced formal parameter #endif #endif #include #include #include #ifdef SUPPRESS_C4100 #if defined(_WIN32) && defined( _MSC_VER ) #pragma warning(pop) #endif #endif struct foo{}; bool operator<(foo,foo){return false;} int main() { boost::multi_index_container<foo> c; } Can you double check you didn't make any mistake? If the additional warnings still pop up, can you paste them to a file and post it? Also, this should proably be fixed at the level of boost/detail/allocator_utilities.hpp. If you put a ticket so that I remember I'll try to get at it in a few days.
