Could be. What does the error message say?

I'm thinking that the lambda function is not properly converted to a pointer to a function.

An escape route may be to use std::sort() with a lambda taking two void*.

The first error is: 1>c:\libraries\boost\boost_1_47_0\boost\utility\result_of.hpp(79): error C2903: 'result' : symbol is neither a class template nor a function template

changing to void* results in the same error.

I'm saying use std::sort() with void* arguments.

// lst.sort([&] (const A& v1, const A& v2) ->bool {return false;}); lst.sort([] (const A* v1, const A* v2) ->bool {return false;});

The first one is the correct one. But I think the problem is with indirect_fun, or the code surrounding it. Does this work: auto x = <lambda>; boost::indirect_fun fun(x); ? -Thorsten
