ERROR LINK2019 when using 2-D poisson solver

In the Intel visual fortran 10with Miscrosoft visual studio 2005, Ican't compile successfully the code example given by manual of MKL poisson library witherrors:

I have configured the compiler as:
1. adding tools->Options->Intel Fortran->LibrariesC:\Program Files\Intel\MKL\10.0.012\ia32\lib
Include:C:\Program Files\Intel\MKL\10.0.012\include
2.InProject > Properties > Linker > Input-> the Additional Dependencies line, insert:
mkl_intel_c.lib mkl_intel_thread.lib mkl_solver.lib mkl_core.lib libguide.lib
3. The MKl lib directory is also addedas the project additional library directories.

Note: I have successfully using many other MKL libraries, such asmkl_dfti and mkl_trig_transforms, butmkl_poisson didn't work.How do I resolve this problem?

Hello zlh007,

The newest versions of Intel Visual Fortran Compiler 11.1.048 and MKL 10.2 Update 2 is availible now. Please try to use them. You can download it from the Registration Center.

Also may be this article will be useful for you.

Thanks,
Art

Thanks for your reply! MyIVF compliler is 10.1.011 and MKL is 10.0.011.Can't the poissonlibrary work OK in this environment? Is there any other method to resolve my problem besides installing the newcompliler and MKL?

I have update my IVF and MKL to new version, the 2-D helmholtz solver (using the example code given by MKL) can be compiled OK! Thanks!
