Environment: Windows SDK 10.0.15063
Affected products: Intel(R) C++ Compiler 18.0 and previous versions.
Problem Description :
This guard macro is defined inside Intel mathimf.h to make sure Microsoft's math header is not included as shown below:
#if defined(_WIN32) || defined(_WIN64) # if defined(_INC_MATH) # error "<mathimf.h> is incompatible with system <math.h>!" # else # define _INC_MATH /* Prevent possible inclusion of MS <math.h> below */ # define __MATH_H_INCLUDED /* Prevent possible inclusion of Intel <math.h> below */ # define __COMPLEX_H_INCLUDED /* Prevent possible inclusion of Intel <complex.h> below */ # endif #endif
In versions of Windows SDK prior to 10.0.15063.0, the math header from Microsoft had the following guard macro:
#ifndef _INC_MATH #define _INC_MATH
But with Windows SDK 10.0.15063.0 and above, the guard macro is taken away (please check corecrt_math.h shipped with Microsoft Compiler):
#pragma once #define _INC_MATH
Test Program to reproduce the issue:
#include<mathimf.h> #include<memory>
