Error in Visual C++ program with Intel MKL BLAS routine.

Hi All

The following is the C++ program I am trying to compile in VC++ 2005.

I got the following error :

error LNK2019: unresolved external symbol _dasum referenced in function _main

The following is my code:

#include
#include "mkl.h"
using namespace std;

int main()
{
const int n = 100;
int INCR = 1;
double A;
int i;
double result;

for(i=0; i A = (double)i;
}
result = dasum(&n, A, &INCR);
cout << result;
return 0;
}

Can someone help me to resolve the problem ?

What libraries have you added to your link line? For a 32-bit system something like the following could be used:

mkl_intel_c.lib mkl_intel_thread.lib mkl_core.lib libiomp5md.lib

Quoting - Todd Rosenquist (Intel)

What libraries have you added to your link line? For a 32-bit system something like the following could be used:

mkl_intel_c.lib mkl_intel_thread.lib mkl_core.lib libiomp5md.lib

Todd

Yeah I believe it is the problem of not linking to the libraries.

How to add libraries to the link line? (I have added MKL library path in VC++ directories.)

Can you please elobrate you explanation?

Appreciable for your valuable time.

Hi Satakarni,

Hi Below you can find short description for compiling and linking program with Intel MKL v.10.0 using the Microsoft* Visual Studio* 2008 or Microsoft* Visual Studio* 2005:

Select View Solution Explorer (and make sure this window is active).
Select Tools Options Projects and Solutions VC++ Directories.
In the drop down menu titled Show directories for:, select Include Files, and then type in the directory for the Intel MKL include files (e.g. default: C:Program FilesIntelMKL10.0include).
In the drop down menu titled Show directories for: select Library Files, and then type in the directory for the Intel MKL library files (e.g. default: C:Program FilesIntelMKL10.0ia32lib).
In the drop down menu titled Show directories for: select Executable Files, and then type in the directory for the Intel MKL executable files (e.g. default: C:Program FilesIntelMKL10.0ia32bin).
On the main toolbar select Project Properties Configuration Properties Linker Input and in the "Additional Dependencies" line, add the libraries you require

As Todd mentioned, for a 32-bit system something like the following could be used:

mkl_intel_c.lib mkl_intel_thread.lib mkl_core.lib libiomp5md.lib

For more information about Linking application with Intel MKL version 10.0 you can find in userguide.pdf chapter 5 ).
