Intel C++ compiler Intel Parallel XE 19.1 gives random errors from Visual studio code for inclusion of or

Question

I am using Intel Parallel XE (R) C++ Intel(R) 64 Compiler for applications running on Intel(R) 64, Version 19.1.0.166 Build 20191121 and Visual Studios Professional 2019 (MSVC\14.27.29110)

here is a simple sample code which gives the error while compilation:

#include<iostream>
#include<map>
int main()
{
std::cout<<"Hello Mallasarj , this is Intel compiler"<<std::endl;
std::map<int, int> mp;
mp.insert({ 2, 30 });

return 1;
}

Errors report while compilation :

compilation aborted for Intel.cpp (code 4)

C:\Users\z0046wdt\Desktop>icl /EHsc Intel.cpp /Feintel.exe

Same fails if I include <map> or <set> . Can anyone please suggest what is going wrong?

Without deeper knowledge: The Intel compiler might provide it's own standard libraries. However, it seems you compiled against the libraries provided by Visual Studio and this might be the cause for the confusion of your compiler. — Scheff's Cat, Oct 16 '20 at 11:28
Concerning my guess: I found [Get Started with Parallel STL](https://software.intel.com/content/www/us/en/develop/articles/get-started-with-parallel-stl.html): _Parallel STL is available as a part of Intel® Parallel Studio XE and Intel® System Studio._ So, it might be necessary to adjust the include paths and other settings so that the correct standard libraries are used. — Scheff's Cat, Oct 16 '20 at 11:32
Now I am using Visual Studios 16.4 and Intel 19.1.3 (Latest PSXE 2020 Update 4).But still I am facing the issues. Can anyone suggest why? — MALLASARJ SULEBHANVI, Nov 17 '20 at 12:30
Please, note the `VC\Tools\MSVC\14.27.29110\include` parts in your error messages you got. It looks like the compiler tries to use the SDK shipped with Visual Studio. If you want to use a different compiler in Visual Studio (which is a reasonable option) then you have to ensure to use the corresponding SDK with it. So, it seems your project settings are just wrong. Either start with the appropriate project template or, at least, configure your project to use the intended SDK for your compiler. — Scheff's Cat, Nov 17 '20 at 13:40
Btw. what I cannot resist to ask myself: C++ on its own is not that easy-peazy but parallel programming is yet another load. Parallel programming in C++ is somehow like the multiplication of hardness. So, if you're a beginner (like we all were once) why do you start with rocket science while it would make more sense to learn to go by bicycle first? Wouldn't it make more sense to learn the basics of C++ first? For this, a Visual Studio out-of-the-box (with the native compiler shipped within) wouldn't be the worst choice. — Scheff's Cat, Nov 17 '20 at 13:45
