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.
