Pleora eBus SDK library missing 3 functions?

I use CentOS 7, Qt-creator with qt5, with c++ with gcc-g++ compiler.

It seems like the pleora eBus SDK library is missing 3 functions.

1. function named PvSleepMs(int ms)
2. function named PvKbHit()
3. function named PvGetChar()

Am I missing something?

these are my includes

#include "settings.h"
#include <QList>
#include <QDesktopServices>

#include <PvSampleUtils.h>
#include <PvDevice.h>
#include <PvDeviceGEV.h>
#include <PvDeviceU3V.h>
#include <PvStream.h>
#include <PvStreamGEV.h>
#include <PvStreamU3V.h>
#include <PvBuffer.h>

#include <list>
#include <string.h>
#include <math.h>
#include <PvGenStateStack.h>

these are my error messeges
