Cannot open include file: 'atlbase.h': No such file or directory

Question

Please have a look at the following code

#define _ATL_APARTMENT_THREADED

#include <atlbase.h>
//You may derive a class from CComModule and use it if you want to override something,
//but do not change the name of _Module
extern CComModule _Module;
#include <atlcom.h>

#include <sapi.h>
#include <iostream>

using namespace std;

int main(int argc, char* argv[])
{
 cout << "Hello" << endl;
 ISpVoice * pVoice = NULL;

 if (FAILED(::CoInitialize(NULL)))
     return FALSE;

 HRESULT hr = CoCreateInstance(CLSID_SpVoice, NULL, CLSCTX_ALL, IID_ISpVoice, (void **)&pVoice);
 if( SUCCEEDED( hr ) )
 {
     cout << "Succeeded" << endl;
     hr = pVoice->Speak(L"Hello world", 0, NULL);
     pVoice->Release();
     pVoice = NULL;
 }
 else
 {
     cout << "Not succeeded" << endl;
 }

 ::CoUninitialize();
 return TRUE;
}

I am using QT. When I run this code, I get the error

Cannot open include file: 'atlbase.h': No such file or directory

I noticed that I do not have the files atlbase.h or atlcom.h in my machine. However, this code runs without error in my laptop, and I got those 2 files there.

I am thinking about getting a copy of those 2 files into my desktop computer and will it work? If yes, to which folder do I have to copy them? I am new to Windows programming, QT and speech.

Answer 1

For me these files are located here:

VS2010 - C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\atlmfc\include\atlbase.h
VS2008 - C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\atlmfc\include\atlbase.h

Please note ATL is part of Microsoft Visual Studio (but not the Express Edition). If you need get ATL for Express please take a look at this topic How to add WTL and ATL to visual studio c++ express 2008

I don't think copying atlbase.h and atlcom.hwill help you. You might try to get all atl*.h files and install required Microsoft Visual C++ Redistributable package.
