How to compile the example C# wrapper on a 64bit server to call DGEMM

[srlawton]

Hi, I'm really stuck.

I have previously successfully compiled the Example C# wrapper to call DGemm on a 32 bit machine, creating MKL.DLL - C# wrapper which calls the Intel MKL DLLs

The following command worked just fine:

nmake ia32 mklroot="C:\\\\Program Files\\\\Intel\\\\MKL\\\\10.2.1.019"

I have now moved to an Intel 64 bit server and have installed Visual Studio 2008 SP1.

From a Visual Studio 2008 Command Prompt on the 64 bit machine (Windows 2003 Server)

Upon calling:

C:\\\\Temp\\\\Intel_MKL_C#_Examples>nmake ia64 MKLROOT="c:\\\\program files\\\\intel\\\\mkl\\\\10.2.0.014\\\\"

I get:

Microsoft Program Maintenance Utility Version 9.00.30729.01

Add path of the MKL libraries to the lib environment variable
set lib=%MKLROOT%\\\\ia64\\\\lib;%lib%

Stop.
NMAKE : fatal error U1077: '"E:\\\\Program Files (x86)\\\\Microsoft Visual Studio 9.0\\\\VC\\\\BIN\\\\nmake.EXE"' : return code '0x2'

My paths seem Ok:

echo %lib%
"C:\\\\Program Files\\\\Intel\\\\MKL\\\\10.2.0.014\\\\ia64\\\\lib"

echo %MKLRoot%
"c:\\\\program files\\\\intel\\\\mkl\\\\10.2.0.014\\\\"

it seems to be failing at the end: module machine type 'X86' conflicts with target machine type 'IA64'.

Any ideas how I can get a 64 bit version of the DLL built ?

Thanks in advance

Steve

Stephen, i guess your target mashine type is not 'IA64' ( aka Itanium), but 'em64t' ( aka Xeon).

So, add path of the MKL libraries to the lib environment variableset lib=%MKLROOT%\\em64t\\lib;%lib%, instead of%MKLROOT%\\ia64\\lib;%lib%

Just for your information - please look at the KB article explains whatIA-32, Intel 64 and IA-64 Architecture means

Gennady, thanks.

I've made life difficult for myself today.

Advice to everyone, when installing Visual Studio 2008, select "Full" install not "Default", this gives you the x64 bit compiler + 64 bit V Studio Command Prompt. It may take a bit longer to install but atleast you will have the full suite.

Everything works once you have the right software installed.
