Looks like the Most Vexing Parse. Try adding parens:

array_type scores((extents[1][1]));

I tried 3 different things and each one gives a different error:

1. array_type scores((extents[1][1])); error: expected identifier before С(Т token

2. array_type::extent_gen extents;а

array_type scores((boost::extents[1][1]));а

long list of errors:ааexpected identifier before С(Т token

error: expected unqualified-id before С[Т token

error: expected С)Т before С[Т token

error: expected С)Т before С[Т token

error: СscoresТ declared as function returning an array

error: expected С;Т before С)Т token

3. array_type::extent_gen extents;а

array_type scores(boost::extents[1][1]);а

error: Сboost::extentsТ has not been declared

needless to say i am going crazy with the compile errors. I am using Boost Version: 1.40.0.1 on Ubuntu 10.04 (in case this helps...)

thanks
