1. Give a complete problem description.
   A complete, clear problem report (with a test case, if necessary) helps us diagnose the problem and get a solution to you quickly.
   
   For Example:
   The linker error occurred when I built an application using the Intel® Math Kernel Library.
   
   Include exact error message:
   (FourierTest.obj : error LNK2001: unresolved external symbol "void __cdecl vdsincos(int *,double const * const,double * const,double * const)" (?vdsincos@@YAXPAHQBNQAN2@Z) Release/TestReconstruction.exe : fatal error LNK1120: 1 unresolved externals
   
   Include exact library names, machine environment and version numbers:
   I am linking mkl_c.lib and libguide.lib from the ia32 subdirectory and I am working on an Intel® Pentium® 4 processor machine using Microsoft Visual C++* .NET 2003, Intel® Math Kernel Library 8.0, Package ID: w_mkl_p_8.0.017
   
   Include test cases if possible:
   Attached is the project file with source code, and it also includes compiler and linker options.
   
   Additionally, please provide detailed development environment information.
