Hello again, Linking... tyfirty.lib(Exceptions.obj) : error LNK2001: unresolved external symbol "char const * __stdcall DXGetErrorString8A(long)" (?DXGetErrorString8A@@YGPBDJ@Z) tyfirty.lib(CD3DFunctions.obj) : error LNK2001: unresolved external symbol _D3DXIntersect@32 SkinMesh.exe : fatal error LNK1120: 2 unresolved externals Error executing link.exe. SkinMesh.exe - 3 error(s), 0 warning(s) How can i solve it ? Please help me !!!

The DXGetErrorString method needs the lib dxerr8.lib AFAIK.

I added dxerr8.lib to my project but i still get the error

Are you linking with d3dx.lib ?
HDATA
HDATA
Yes,
It''s the list of the libraries which i added them to my project:

kernel32.lib user32.lib gdi32.lib winspool.lib comdlg32.lib advapi32.lib shell32.lib ole32.lib oleaut32.lib uuid.lib odbc32.lib odbccp32.lib d3d8.lib d3dx8.lib dxguid.lib d3dxof.lib winmm.lib dsound.lib Dxerr8.lib tyfirty.lib

Do a search in the SDK docs and find what LIB files and header files it needs.

I think I''m getting a similar problem, the compiler keeps telling me I have unresolved external symbol errors, everything seems to be linked OK, but the errors keep coming up.

I''m using VC++.net and have DX8.1 and 8.1 SDK installed.

Here''s the errors and the code.

error LNK2019: unresolved external symbol _D3DXMatrixLookAtLH@16 referenced in function "int __cdecl DoInit(void)" (?DoInit@@YAHXZ)
error LNK2019: unresolved external symbol _D3DXMatrixPerspectiveFovLH@20 referenced in function "int __cdecl DoInit(void)" (?DoInit@@YAHXZ)
error LNK2019: unresolved external symbol _Direct3DCreate8@4 referenced in function "int __cdecl DoInit(void)" (?DoInit@@YAHXZ)
error LNK2019: unresolved external symbol _D3DXMatrixRotationY@8 referenced in function "int __cdecl DoFrame(void)" (?DoFrame@@YAHXZ)
error LNK2019: unresolved external symbol __imp__timeGetTime@0 referenced in function "int __cdecl DoFrame(void)" (?DoFrame@@YAHXZ)

I''m not sure if I''m right... but you need to link to your directx libraries before you link to the normal ones... just a guess

best of luck

...or it could be a path issue, but the fact the fact that timeGetTime is still unresolved bothers me, unless it''s getting left out simply because the linker can''t find the other things...In that case it''s almost certainly a path issue, or something like the quirk mentioned above.

Sorry it''s taken so long to respond.

The DX include and lib files are listed on the top of the paths list it''s C:\DXSDK\include and C:\DXSDK\lib here''s the others in the list just in case I''m missing something.

C:\DXSDK\lib
$(VCInstallDir)lib
$(VCInstallDir)atlmfc\lib
$(VCInstallDir)PlatformSDK\lib\prerelease
$(VCInstallDir)PlatformSDK\lib
$(FrameworkSDKDir)lib

C:\DXSDK\include
$(VCInstallDir)include
$(VCInstallDir)atlmfc\include
$(VCInstallDir)PlatformSDK\include\prerelease
$(VCInstallDir)PlatformSDK\include
$(FrameworkSDKDir)include
