I have often come across such errors in compiling my code. Often,
including one or more other headers solves the problem.
try including one or more of the following:
expression_types.hpp
matrix_proxy.hpp
matrix_expression.hpp
traits.hpp
you could try other header files that you suspect contain typedefs of
closure_type (there are so many!).
This is only a hack though - the best I have come up with.
cheers
