The question is how you build the plugin. Are you just calling the compiler on 
the command line? This will not be likely to work because you may be calling a 
different compiler than used to compile deal.II, you may be passing a 
different set of flags, etc. Use the approach using the CMakeLists.txt file 
outlined in the manual instead -- this will set up the compiler, the flags, 
the include files, etc, all correctly.
