Direct Draw *RESOLVED

[petrus]

Hello,
I'm new to Direct Draw and i want to learn it.
I have source code to a program, but when i build it, I get errors:

--------------------Configuration: Direct Draw1 - Win32 Debug--------------------
Compiling...
DD1.CPP
C:\Documents and Settings\Peter Backman\Mina dokument\Programmering\C++\DDraw\Direct Draw1\DD1.CPP(7) : error C2146: syntax error : missing ';' before identifier 'g_pdd'

Error executing cl.exe.

Direct Draw1.exe - 3 error(s), 0 warning(s)


By the way, here is the Source:
#include <afxwin.h>
#include <ddraw.h>
#include <ctime>
#include <cstdlib>

HRESULT hRet;
LPDIRECTDRAW7 g_pdd; //The 3 errors is pointing to this.

DDSCAPS2 ddsc;

class cDDProg : public CWinApp
{
public:
virtual BOOL InitInstance();
};

cDDProg DDProgram;

class cDDWind : public CFrameWnd
{
CStatic* WelcomeStatic;

public:



cDDWind();
};

BOOL cDDProg::InitInstance()
{
m_pMainWnd = new cDDWind();
m_pMainWnd->ShowWindow(m_nCmdShow);
m_pMainWnd->UpdateWindow();



return TRUE;
}

cDDWind::cDDWind()
{


WelcomeStatic = new CStatic();
Create(NULL,"Direct Draw Test.",WS_OVERLAPPEDWINDOW,CRect(100,100,500,300));

WelcomeStatic->Create("Welcome to the Direct Draw test by Peter Backman!",WS_CHILD|WS_VISIBLE,CRect(0,0,400,200),this);


//Initialize Direct Draw

hRet = DirectDrawCreateEx(NULL,(void**)&g_pdd,IID_IDirectDraw7,NULL);

if (hRet != DD_OK)
MessageBox("DirectDrawEx Failed!","Direct Draw",MB_EXCLAMATION);

//Now, set the cooperative level

hRet = g_pdd->SetCooperativeLevel(cDDWind::m_hWnd,DDSCL_FULLSCREEN|DDSCL_EXCLUSIVE);

if (hRet != DD_OK)
MessageBox("SetCooperativeLevel Failed","Direct Draw",MB_EXCLAMATION);

//Set display mode, 640x480 with 16 bit color deepth
hRet = g_pdd->SetDisplayMode(640,480,16,0,0);

if (hRet != DD_OK)
MessageBox("SetDisplayMode Failed!","Direct Draw",MB_EXCLAMATION);

//Prepare primary surface info

ZeroMemory(&ddsd,sizeof(ddsd));

}

#include <ddraw.h> is the problem. This will include the version of the ddraw header that comes with MSVC, which is something like DDraw 3 or 4. I believe that you need to find a copy of the DX7 SDK somewhere, and install it to get the headers you need.

[CornedBee]

And then in the general settings of VC++ you must list the include path of the DX7 SDK BEFORE the path of VC++'s standard includes.

[petrus]

I've installed the DirectX8 SDK, and I've added the DDRAW.lib to the workspace...

[CornedBee]

Make sure the library and include paths of the SDK come before the VC++ standard paths.

VC++6: Tools->Options->Directories
For both library files and include files your DX SDK directories should be the first listed ones.

[petrus]

I have 4 items in the list there:

1. C:\mssdk\include
2. C:\Program\Microsoft Visual Studio\VC98\INCLUDE
3. C:\Program\Microsoft Visual Studio\VC98\MFC\INCLUDE
4. C:\Program\Microsoft Visual Studio\VC98\ATL\INCLUDE

[petrus]

HELP!
I don't have the "C:\mssdk\include\" directory!!!

[CornedBee]

Where did you install the DirectX SDK to?

[petrus]

I've installed it into C:\mssdk\, and i have files there, but no Include directory.

[petrus]

Ah, the setup didn't install all the libs and includes, so i copied them by my self to the C:\mssdk\ directory.
Now, the 3 errors change into another 3 errors:

--------------------Configuration: Direct Draw1 - Win32 Debug--------------------
Compiling...
DD1.CPP

DD1.OBJ : error LNK2001: unresolved external symbol _DirectDrawCreateEx@16
DD1.OBJ : error LNK2001: unresolved external symbol _IID_IDirectDraw7
Debug/Direct Draw1.exe : fatal error LNK1120: 2 unresolved externals
Error executing link.exe.

Direct Draw1.exe - 3 error(s), 0 warning(s)

[Zaei]

You have to add ddraw.lib to your import library list in the project settings.

Z.

[CornedBee]

And dxguid.lib

[petrus]

Now I have included ddraw.lib and dxguid.lib, but now I have one error:

--------------------Configuration: Direct Draw1 - Win32 Debug--------------------

DD1.CPP
Linking...
DD1.OBJ : error LNK2001: unresolved external symbol _DirectDrawCreateEx@16

Direct Draw1.exe - 2 error(s), 0 warning(s)

[petrus]

Sorry, two errors

[Zaei]

Try ddraw7.lib. Just guessing here =).

Z.

[petrus]

BTW, here's the source.

[petrus]

I'm trying to learn Direct Draw out of a book I have.
Here's a quotation from the book:

"Often I include all the library files because the compiler will use only what it needs; you will use only ddraw.lib."

[petrus]

OK, thank you guys, when I read that quatation, I started to think if I should add all Librarys.
Strange that I have to add all librarys to get it work...

[CornedBee]

VC++ is strange sometimes.

VC++ is strange sometimes.

Some are stranger I remember when I was using the SGI compiler, I had to include libraries like this:

${CC} ${CCFLAGS} -o awb.irix6 ${OBJ_FILES} -lutil -lhgrafix -lwkit -lhgrafix -lutil -lX

Note the doubling up, in the opposite order. Was the only way to fix a load of unresolved symbols.

Just so you know it ain't just MS

[CornedBee]

That's ridiculous!

[parksie]

That's what I said
