I'm using a recursive_directory_iterator on an Android ARM device (armeabi-v7a, clang compiler, API 15, LLVM STL). The exception I get comes from directory_iterator_increment in operations.cpp (when it does the dir_itr_increment() call and checks the `temp_ec` variable, there is a throw below that).

The what() of the exception says:

boost::filesystem::directory_iterator::operator++: Function not implemented: "/data/ziosk/content/Common/DemoMode/font"

I doubt this is a permissions issue. Which function is not implemented? Is this a POSIX / LIBC issue? I have no idea at this point...

In the source code for operations.cpp in the directory_iterator_increment function you can see where the exception is being thrown. After building filesystem, try tracing into the above function to see what is going on.
