I hope I've got the right list here (first time poster), my apologies if I don't :-). boost::array fails a ContainerConcept check in 1.32 due to it's lack of a const_pointer typedef: #include <boost/array.hpp> #include <boost/concept_check.hpp> int main ( void ) { using namespace boost; function_requires< ContainerConcept< array< int , 5 > > >(); } Resulting errors using MinGW's GCC 3.4.2: boost/concept_check.hpp: In instantiation of `boost::ContainerConcept<boost::array<int, 5u> >': boost/concept_check.hpp:48: instantiated from `void boost::function_requires(boost::mpl::identity<T>*) [with Concept = boost::ContainerConcept<boost::array<int, 5u> >]' ../main.cc:7: instantiated from here boost/concept_check.hpp:683: error: no type named `const_pointer' in `class boost::array<int, 5u>' I noticed the BCCL links to SGI's documentation for the Contanier concept, which actually does not appear to list a const_pointer (see http://www.sgi.com/tech/stl/Container.html), although it does include pointer, which array is lacking. As allready mentioned, I tried this with 1.32 - I also tried the CVS head version, no idea if that's the latest that I should be checking or what (CVS newbie), but this wasn't fixed in there. In any case, adding const_pointer to array allows the simple example to compile - here's a patch which adds this and pointer (hopefully in an OK format - I'm a solo hobbyist, not used to working on large projects) which adds them... let me know if I can be of any other help :-).
