 Just guessing.
 You want to use 'opendir'.
 You need a prototype.
  grep opendir /usr/include/*.h
       Nope, not there.
  grep opendir /usr/include/sys/*.h
       OK, it's in /usr/include/sys/dirent.h
  great, let's try
      #include <sys/dirent.h>

   WRONG!
    For C++, you need the
#ifdef __cplusplus
extern "C" {
...
    that's in /usr/include/dirent.h

Recompile SVIntfLoader using the correct include file.
