Intel MKL 10.3 with C# 32-bit and 64-bit

Jump to solution

I am using Intel MKL 10.3 with Visual Studio 2010 and Windows 7 (64-bit). I am trying to use the MKL functions in my C# code. I need to create 32-bit and 64-bit versions of my C# program.
I followed the instructions under the heading Building the Examples with IntelMKL 10.3athttp://software.intel.com/en-us/articles/using-intel-mkl-in-your-c-program. I was able to successfully execute the command nmake intel64 MKLREDIST="c:\\Program Files\\Intel\\ComposerXE-2011\\redist" from both the Visual Studio Command Prompt (2010) and Visual Studio x64 Win64 Command Prompt (2010), however, I when I tried to execute nmake ia32 MKLREDIST="c:\\Program Files\\Intel\\ComposerXE-2011\\redist" from either prompt...I got the following error:
C:\\Program Files (x86)\\Intel\\ComposerXE-2011\\mkl\\tools\\builder>nmake ia32 MKLREDIST="C:\\Program Files (x86)\\Intel\\ComposerXE-2011\\redist" Microsoft Program Maintenance Utility Version 10.00.30319.01 Copyright (C) Microsoft Corporation.

The strange thing about this whole situation is that I am able to compile and execute a 32-bit version of my C# program without any issues; however, when I compile and run the 64-bit version, I get the following run-time error:
The program '[6568] IntelMKL.vshost.exe: Managed (v4.0.30319)' has exited with code 1 (0x1).
Can anyone help me figure out what I need to do to use Intel MKL 10.3 with 32- and 64-bit versions of my C# program? Thanks!

## if you get the message:
## LINK : fatal error LNK1181: cannot open input file 'bufferoverflowu.lib'

## add option 'buf_lib=' or comment the line below
buf_lib = bufferoverflowu.lib

Hi Gennady,

Thank you very much for responding to my question. I have been referring to the link that you provided...unless I'm missing something, it doesn't address the problems that I'm experiencing. I just tried to re-run the "ia32" version of the nmake command today and now I'm getting a different error:
C:\Users\poibri01\Desktop\Intel_MKL_C#_Examples_03>nmake ia32 MKLREDIST="C:\Program Files (x86)\Intel\ComposerXE-2011\redist" Microsoft Program Maintenance Utility Version 10.00.30319.01 Copyright (C) Microsoft Corporation.

NMAKE : fatal error U1077: '"c:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\BIN\amd64\nmake.EXE"' : return code '0x2' Stop.

Just to summarize my situation:

  1. I am using Visual Studio 2010 with Intel MKL 10.3 and Windows 7 (64-bit).
  2. The following paths are in my PATH environment variable:
    C:\Program Files (x86)\Intel\ComposerXE-2011\redist\ia32; C:\Program Files (x86)\Intel\ComposerXE-2011\redist\intel64; C:\Program Files (x86)\Intel\ComposerXE-2011\redist\ia32\compiler; C:\Program Files (x86)\Intel\ComposerXE-2011\redist\intel64\compiler; C:\Program Files (x86)\Intel\ComposerXE-2011\mkl\lib\ia32; C:\Program Files (x86)\Intel\ComposerXE-2011\mkl\lib\intel64
  3. I am able to run the "intel64" version of the nmake command from both the "Visual Studio Command Prompt (2010)" and the "Visual Studio x64 Win64 Command Prompt (2010)":
    nmake intel64 MKLREDIST="C:\Program Files (x86)\Intel\ComposerXE-2011\redist"
  4. I am NOT able to run the "ia32" version of the nmake command from either command prompt:
    nmake ia32 MKLREDIST="C:\Program Files (x86)\Intel\ComposerXE-2011\redist"
  5. I am able to compile and run a 32-bit version of my C# program using the MKL functions.
  6. I get a runtime error when I run a 64-bit version of my C# program:
    The program '[3640] IntelMKL.vshost.exe: Managed (v4.0.30319)' has exited with code 1 (0x1).

@mecej4: Thank you very much for your help...after following your suggestion to use the makefile inside "Intel_MKL_C#_Examples_02.zip" I was able to successfully compile and run both versions (32-bit and 64-bit) of my C# program. This is a huge relief...I spent hours trying to get this to work.Again, I really appreciate all your time and help. I wish you the very best! =)
