Hello,
here is a test to use a random generator funtion from the math kernel library:
---
#include <iostream>
#include <mathimf.h>
#include <mkl.h>
int main()
{
unsigned int iseeds[32];
VSLStreamStatePtr iRNDStream[2];
iseeds[0] = 123456;
memset(iRNDStream, 0, sizeof(iRNDStream));
vslNewStreamEx(&iRNDStream[0], VSL_BRNG_MCG59, 1, iseeds);
std::cout << "Hello World!\n";
}
--
The call to vslNewStreamEx immediately kills the application. It doesn matter
if I apply the sequential or the parallel version.
I copy the dll (mkl_sequential.2.dll, mkl_intel_thread.2.dll) manually to the executable folder.
I have used that functionality very successful in the older C Compiler back in 2021 but
I fail to re-use it in the current version.
What do I wrong ?
I'm using VS2022, 64 Bit Compile Mode
Thank you

Hello,
I finally found the missing part:
The system "Path" variable needs to have the mkl path included:
C:\Program Files (x86)\Intel\oneAPI\mkl\latest\redist\intel64
Actually, that is quite natural but it would be nice if the oneApi setup would do this for us under Windows.
You may close this thread.
Thansk again
Kind regards
Marcus

Hi,
Thanks for posting in Intel Communities.
Could you please let us know the Intel C++ compiler, Intel MKL version, and Microsoft Visual Studio 2022 sub-version you are using?
At our end, when we tried to run the sample reproducer code provided by you on Visual Studio 2022, we are able to run it without any errors in both sequential as well as parallel mode. Please find the below-attached screenshots for more details.
Could you please try running on the Intel oneAPI command prompt and let us know if you are still facing any errors?
Thanks & Regards,
Varsha

But: From your screen shot I see that you run the example within visual studio in debugging mode. When I try this
I get the same result as you. If I compile in release mode and run again within visual studio I get also the
desired result.
But when I run the generated executable from a windows command prompt (or just double click on the exe) it doesnt work.
Perhaps something to do with the referenced dlls ?
(I had to manually search for them and copy in the exe folder)

Some additional info:
If I run the TestApp.exe from the Intel oneApi command line it works - it doesn even complain about a missing dll.
If I run it from windows it complains about the missing dll: mkl_intel_thread.2.dll
If I copy this dll from
C:\Program Files (x86)\Intel\oneAPI\mkl\2023.1.0\redist\intel64
and put it in the exe folder I can start the test exe by double click but it fails or is killed and does nothing.
I just tried a different call to the mkl: mkl_get_version_string(buf, 128); --> same result.
Thats really confusing:
Why it magically runs under the control of Visual Studion and/or the Intel oneApi command line tool
but not in a native way under Windows ?
I am lost ...What I have to do ?
Thanks in advance!

Hi,
Thanks for the details and reply.
>>Why it magically runs under the control of Visual Studion and/or the Intel oneApi command line tool but not in a native way under Windows ?
Yes, while using both the Intel oneAPI command prompt as well as setting Intel oneAPI in Microsoft Visual Studio the Intel Environment will be initialized.
But when you try to do it on the Windows command prompt you need to initialize the oneAPI environment so that it will include all the necessary files and path that is required. You can also initialize by using the below command on the Windows command prompt and try running as same in Intel oneAPI Command Prompt. Please find the below screenshot for more information.
"C:\Program Files (x86)\Intel\oneAPI\setvars.bat"
Could you please try and let us know if you have any other queries?
Thanks & Regards,
Varsha

Hello Varsha,
I tried the command with mixed success:
If I open a CMD shell under windows and run the setvar script it makes the TestApp.exe working within the
command shell.
However, I'm still not able to get the TestApp.exe running in the standard windows environment by simply
double clicking on that exe. This works on your side ?
Seems the question is: What is needed to be setup globally under windows in order to make the mkl running?
Sorry, I looked around for a while in the documentation but so far no luck.
PS: I'm using Windows 10 Pro
Thanks and kind regards
