Can't build test sample using VML for x64 platfom: linker says about unresolved externals

Hello.

Actually, the subject described in thread title name. When I'm build a sample for x86 platform, it builds without errors, runs and works correctly. And if I'm try to build for x64 platform - linker says about errors like this:

Error 1 error LNK2019: unresolved external symbol mkl_vml_core_e9_vml_zAdd referenced in function vzadd mkl_intel_lp64.lib Using_VML
Error 2 error LNK2019: unresolved external symbol mkl_vml_core_h8_vml_zAdd referenced in function vzadd mkl_intel_lp64.lib Using_VML
Error 3 error LNK2019: unresolved external symbol mkl_vml_core_y8_vml_zAdd referenced in function vzadd mkl_intel_lp64.lib Using_VML
Error 4 error LNK2019: unresolved external symbol mkl_vml_core_u8_vml_zAdd referenced in function vzadd mkl_intel_lp64.lib Using_VML

I'm using VisualStudio 2008 and C++ project.

For x64 platform some project settings are changes:

Additional directory for linker isC:\\Program Files\\Intel\\MKL\\10.2.3.029\\em64t\\lib\\

Additional dependencies for linker too are libiomp5md.lib mkl_core_dll.lib mkl_intel_thread_dll.lib mkl_intel_lp64.lib mkl_solver_lp64.lib

Target machine is x64 of course

And environment path for debugging: PATH=C:\\Program Files\\Intel\\MKL\\10.2.3.029\\em64t\\bin\\;$(PATH)

P.S. It take place only if I'm use dynamic linking. If changedependencies from dynamic linking to static (change references frommkl_core_dll.lib mkl_intel_thread_dll.lib tomkl_core.lib mkl_intel_thread.lib) it builds ok.

It's very interesting...

Doesn't the link advisor specify mkl_intel_lp64_dll.lib when using these other dynamic libraries?

Of course! Thank you, Tim.

It's interesting but this references are set by Intel's script intergated to Visual Studio (right click on project name in Project Explorer and use Intel MKL Project Settings). I'm wonder...

it looks like the error. Do you use bundled MKL from Compiler Professional Edition or stanadlone version? What are these versions?

Thank you, Gennady.

I'm use standalone MKL package, version number 10.2.3.029
