icc thinks boost::filesystem3::path is an incomplete type

Question

I am attempting to build a program called Mitsuba with icc. But when I compile, I get lots of errors saying that a type is incomplete. Here are a few examples:

I'm somewhat new to templates, but I think these are saying that the type boost::filesystem3::path is incomplete. Upon inspection of boost/filesystem/path.hpp, this does not appear to be the case.

The file that causes this problem (fresolver.h):

#include <mitsuba/mitsuba.h>
#include <boost/filesystem.hpp>
#include <boost/filesystem/fstream.hpp>
#include <deque>

...

class MTS_EXPORT_CORE FileResolver : public Object {
    ...
private:
    std::deque<fs::path> m_paths;
}

Why does the compile fail, and how can I fix it?
