    copied!<p>I'm coding an application using C# with Visual Studio 2008. I've been reading the documentation that came with the Intel Math Library...and some forums...but couldn't get an answer. </p> <p>Here is where I'm at:</p> <p><strong>Scenario</strong>: Attempting to statically-link MKL v9.x into a managed C++ DLL to calculate FFT, using Visual Studio 2008.</p> <p>Linker command: /OUT:"C:\Projects\Acquisition Toolkit\Mainline\Builds\Debug\AcquisitionToolkit.FFT.dll" /INCREMENTAL /NOLOGO /LIBPATH:"C:\Projects\Acquisition Toolkit\Mainline\Lib\Win32" /DLL /MANIFEST /MANIFESTFILE:"Debug\Win32\AcquisitionToolkit.FFT.dll.intermediate.manifest" /MANIFESTUAC:"level='asInvoker' uiAccess='false'" /DEBUG /ASSEMBLYDEBUG /PDB:"c:\Projects\Acquisition Toolkit\Mainline\Builds\Debug\AcquisitionToolkit.FFT.pdb" /DYNAMICBASE /FIXED:No /NXCOMPAT /MACHINE:X86 /KEYFILE:"AcquisitionToolkit.snk" /ERRORREPORT:PROMPT mkl_c.lib mkl_ia32.lib libguide40.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</p> <p>Getting an unresolved external when linking:</p> <p>1>FFT.obj : warning LNK4248: unresolved typeref token (0100000E) for 'DFTI_DFT_Desc_struct'; image may not run</p> <p>At run-time, it crashes on the call to DftiCreateDescriptor, presumably because it didn't know the format of the descriptor struct:</p> <p>// create the FFT descriptor DFTI_DESCRIPTOR_HANDLE desc; long val = DftiCreateDescriptor(&amp;desc, DFTI_DOUBLE, DFTI_REAL, 1, length);</p> <p>// commit the FFT descriptor DftiCommitDescriptor(desc); We are including the mkl_dfti.h header file. </p> <p>Are there additional header files we need or additional libraries we need to link with? </p> <p>Where is that descriptor struct actually defined?</p> <p>I attempted to dynamically link using the mkl_c_dll.lib, but got the same unresolved external linker warning. </p> <p>Is there some other linker option I need?</p> <p>Please if someone could give me some kind of guidance/help. I'd REALLY appreciate it.</p> <p>Thanks!!</p>
