ippvalarray fails to compile when using Intels Optimized Headers

Hello,

 

I'm not sure why, but when I use Intels Optimized Headers(specifically valarray) the compiler will point out about 66 or so syntax errors. I'm unsure why this is happening.

I'm on Visual Studio 2019.4.1(enterprise) and Intel C++ Compiler version 19.1

Thanks

Can you provide us a test case to reproduce the error along with your command line options?

Sure, my code is a bit complicated so I've written a small example and this one also fails:

#include <valarray>
#include <cstdlib>
#include <iostream>

int main()
{
    int size = 20;
    std::valarray<double> num1(size), num2(size), result(size);

    for (int i = 0; i < size; ++i) {
        num1 = std::rand();
        num2 = std::rand();
    }

    for (int i = 0; i < size; ++i) {
        result = num1 + num2;
    }

    for (int i = 0; i < size; ++i) {
        std::cout << "Value at position " << i << ": " << result << std::endl;
    }
}

 

And here is what I see on the command line from the output of the build log. (I'm seting the option from the properties window, I'm not using the command line):

C:\Program Files (x86)\IntelSWTools\compilers_and_libraries_2020\windows\bin\intel64\icl.exe /c /Qm32 /ZI /nologo /W3 /Od /Quse-intel-optimized-headers /D __INTEL_COMPILER=1910 /D WIN32 /D _DEBUG /D _CONSOLE /D _UNICODE /D UNICODE /EHsc /RTC1 /MDd /GS /permissive- /Zc:wchar_t /Zc:forScope /Fo"Debug\\" /Fd"Debug\vc142.pdb" /Gd /TP /FC l11.cpp

Thanks,

Dominique

With /Quse-intel-optimized-headers flag, I am seeing the below error. Did you see the same?

No I'm not seeing that error. I only see the syntax errors I mentioned. Here is a photo. I've not changed any setting other than using Intel's compiler and "Use Intel optimized headers" in the options window.

When I press on one of the errors to the where its pointing to I see the following:

If /Quse-intel-optimized-headers is broken even on your end, what is the correct way to make use of Intels optimized headers?

I just tested the same code with the same version of Intel's compiler(its the only one I have access to, 19.1) but with the latest version of Visual Studio 2017(15.9.19) and I get the same exact result. 66 syntax errors in ippvalarray and no syntax highlighting for the file.

Both these tests were conducted on Windows 10 Enterprise LTSC 1809

Seem to me that you don't have IPP install or somehow didn't have it linked in correctly.

The compiler and all accompanying tools(vTune, Inspector, etc) all work fine. It can also find the files, it just seems to have a problem interpreting them. I tried on another machine with the default installation of Visual Studio 2017 and the compiler and I get identical results. Have you been able to run the code I posted above? Thanks

Yes, it compiled after I installed IPP
