Hello! I have written a simple application in WinAPI with a small usage of DirectX. And I encountered a problem... When I try to create a wave file object: CWaveFile wavFileObj = new CWaveFile(); The program doesn't compile and writes for this line: C:\Program Files\Microsoft Visual Studio\MyProjects\Button\button.cpp(23) : error C2440: 'initializing' : cannot convert from 'class CWaveFile *' to 'class CWaveFile' No constructor could take the source type, or constructor overload resolution was ambiguous Dunno what's up... but tried a static declaration: CWaveFile wavFileObj; And now it compiles with no errors or warnings. But during the linking it says: button.obj : error LNK2001: unresolved external symbol "public: __thiscall CWaveFile::CWaveFile(void)" (??0CWaveFile@@QAE@XZ) button.obj : error LNK2001: unresolved external symbol "public: __thiscall CWaveFile::~CWaveFile(void)" (??1CWaveFile@@QAE@XZ) What the...? My question is - do I need a special .lib file for the linker to understand CWaveFile? And WHY THERE IS NO reference guide for all the .lib files - so that I could check where this or that belongs? My include section is good, i think: #include <windows.h> #include <d3d9.h> #include <dsound.h> #include <DXUTsound.h> And I have added these .lib's for the linker: dsound.lib dxerr9.lib dxguid.lib d3dx9d.lib d3d9.lib dinput8.lib winmm.lib comctl32.lib kernel32.lib user32.lib gdi32.lib winspool.lib comdlg32.lib advapi32.lib shell32.lib ole32.lib oleaut32.lib uuid.lib odbc32.lib odbccp32.lib Please, anyone...?

assuming C++

CWaveFile wavFileObj = new CWaveFile();

that line should be:

CWaveFile *wavFileObj = new CWaveFile();

note the addition of the asterix.

Thank you guys for help :) Need more...

As for the asterisk - it helped (the same linker errors though) - but it surprises me because in the samples, tutorials or books I have used, there was my version (without asterisk). Strange...

And the main problem. The first thing I did was to add the DXUTsound.cpp to the project. I thought #include <DXUTsound.cpp> was enough. But it isn't :(

The warnings? Don't really know what's up. But the Unicode build frightens me :) Is my addition of DXUTsound.cpp correct? Or should I do it in a more complicated way? What do you mean by 'to compile it yourself'? And is the DXUT really the only way to work with wave files in DirectX???
