Hmm, are you sure that libmlpack.dll has the symbol
mlpack::Log::Assert() in it?  That might be a good place to start
checking.  I am not too familiar with the environment you are using, so
I can't give details on exactly how to check that, just basic ideas.  If
you can verify that the mlpack::Log::Assert() symbol is in the
libmlpack.dll file, then I think the next thing to check is that the
linker is actually being called with libmlpack.dll (on Linux, I'd check
this with 'VERBOSE=1 make', but I don't know exactly what to do in your
situation).

Oh, okay, I see.

These were fixed recently, since the 2.0.1 release, and will be
incorporated into the 2.0.2 release (probably released in the next few
weeks):
