Did you build octave with --enable-dl --enable-shared?
It worked for me:

dima at tumbleweed octave]$ cat testDynamicFunc.cc
#include <octave/oct.h>

DEFUN_DLD (testDynamicFunc, args, , "Test Dynamic Functions.")
{
          double d = 0.0;
            return octave_value(d);
}

[dima at tumbleweed octave]$ mkoctfile -v testDynamicFunc.cc
g++ -c -fPIC -I/usr/local/include/octave-2.1.40 
-I/usr/local/include/octave-2.1.40/octave -I/usr/local/include -mieee-fp -O3 
-mcpu=i686 -march=i686 -pipe testDynamicFunc.cc -o testDynamicFunc.o
cc1plus: warning: changing search order for system directory
