c++ - 英特尔编译器使用“属性“__malloc__”不接受参数的 C++14 检查失败

问题描述

我有以下代码（旨在检测编译器是否支持 C++14）：

#include <memory>
#include <algorithm>

// Check the version language macro, but skip MSVC because
// MSVC reports 199711 even in MSVC 2017.
#if __cplusplus < 201402L && !defined(_MSC_VER) && !defined(__INTEL_COMPILER)
#error "insufficient support for C++14"
#endif

int main()
{
    auto ptr = std::make_unique<int>(42);
    constexpr int max = std::max(0, 1);
    (void) ptr;
    (void) max;
    return 0;
}

使用g++（版本 11.2.1）编译它时，g++ -std=c++14 test.cpp -o test它工作正常。当使用 intel 编译器（版本 2021.3.0（gcc 版本 11.2.1 兼容性））而不是使用 编译它时icpc -std=c++14 test.cpp -o test，它会失败并显示

这里到底出了什么问题，我该如何解决？

简短更新：看起来 CUDA 遇到了类似的问题，并且可能与 glibc 2.34 有关：https ://forums.developer.nvidia.com/t/cuda-11-5-samples-throw-multiple-error-属性-malloc-does-not-take-arguments/192750/15

解决方案

使用 icpc 2021.4 编译和执行共享代码，运行良好。

使用下面的命令来编译代码。icpc -std=c++14

下面是环境细节。

操作系统：Ubuntu 18.04.3 LTS 内核：Linux 4.15.0-76-generic
