IR2test:19:11: error: 'class IRdecode' has no member named 'dumpResultso'; did you mean 'dumpResults'? MyDecoder.dumpResultso();

[phelix001]

Using the PDF instructions, I've tried to compile a few of them and I get this:
IR2test:19:11: error: 'class IRdecode' has no member named 'dumpResultso'; did you mean 'dumpResults'?
MyDecoder.dumpResultso();

I have included:

#include <IRLibRecv.h>
#include <IRLibDecodeBase.h>
#include <IRLib_P01_NEC.h>
#include <IRLibCombo.h>
#include <IRLibAll.h>
