I am trying to use boost.MultiIndex as a class data member and am having difficulty because it seems that calling get<>() will not compile on a NetBSD box (gcc version 4.1.3). The code below illustrates a simple test case. Am I missing something obvious or doing something clearly mistaken? Any help is greatly appreciated. Thanks alot.
