Hello, I have just started to work with DirectX 7 Direct3D. I have worked with DirectDraw before, so I am familiar with linking. I created my first 3D example by using a book as a guide. There are no compile errors, but when I try to link, there are some errors. I am using "d3dutil.h" to help with my projection and view matrices. I have linked to d3dim.lib so that is not my problem. Here is what the link errors say: 3d_start.obj : error LNK2001: unresolved external symbol "long __cdecl D3DUtil_SetProjectionMatrix(struct _D3DMATRIX &,float,float,float,float)" (?D3DUtil_SetProjectionMatrix@@YAJAAU_D3DMATRIX@@MMMM@Z) 3d_start.obj : error LNK2001: unresolved external symbol "long __cdecl D3DUtil_SetViewMatrix(struct _D3DMATRIX &,struct _D3DVECTOR &,struct _D3DVECTOR &,struct _D3DVECTOR &)" (?D3DUtil_SetViewMatrix@@YAJAAU_D3DMATRIX@@AAU_D3DVECTOR@@11@Z) Debug/3d_start.exe : fatal error LNK1120: 2 unresolved externals Error executing link.exe. 3d_start.exe - 3 error(s), 0 warning(s) Any help would be appreciated. I am using Visual C++ 6.0, DirectX 7.0, and I have Windows XP. If you need any more information, let me know. Thank you for your time.
