c++ - 使用 CUDA 和 C++ 运行现有项目

Question

我正在尝试运行 this项目在我的笔记本电脑中。我安装了以下东西。

CUDA:

nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2015 NVIDIA Corporation
Built on Tue_Aug_11_14:27:32_CDT_2015
Cuda compilation tools, release 7.5, V7.5.17

海湾合作委员会:

gcc (Ubuntu 5.4.1-2ubuntu1~16.04) 5.4.1 20160904
Copyright (C) 2015 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

CMake:

cmake version 3.5.1

在 make 期间。项目报错如下。

/usr/include/c++/5/bits/c++0x_warning.h:32:2: error: #error This file requires compiler and library support for the ISO C++ 2011 standard. This support must be enabled with the -std=c++11 or -std=gnu++11 compiler options.

如果我将 set (CMAKE_CXX_STANDARD 11) 添加到 CMakesLists.txt 以支持 c++ 标准 11。我收到以下错误。

现在我不知道如何进行这项工作。我该如何构建这个项目？

Answer 1

std::enable_if_t 仅在 C++14 中引入，因此您应该将所需标准设置为 C++14:

set(CMAKE_CXX_STANDARD 14)
