使用CMake在CUDA中使用std :: filesystem

问题描述

我有一个已经描述过的问题here，但是我正在使用cmake 3.18.0 。

在我的<controls:DataGridTemplateColumn Header="Check"> <controls:DataGridTemplateColumn.CellTemplate> <DataTemplate> <StackPanel Orientation="Horizontal"> <CheckBox Content="{Binding Id}" IsChecked="{Binding IsCheck}" /> </StackPanel> </DataTemplate> </controls:DataGridTemplateColumn.CellTemplate> </controls:DataGridTemplateColumn> 文件中，以下几行用于启用正确的 c ++ 标准：

CMakeLists.txt

但是我仍然收到以下错误消息：set(CMAKE_CXX_STANDARD 17) set(CMAKE_CXX_STANDARD_REQUIRED ON) set(CMAKE_CXX_EXTENSIONS OFF) set(CMAKE_CUDA_STANDARD 17) set(CMAKE_CUDA_STANDARD_REQUIRED ON) set(CMAKE_CUDA_EXTENSIONS OFF) set(CMAKE_CUDA_ARCHITECTURES OFF) set(CMAKE_CUDA_SEPARABLE_COMPILATION ON) set(CMAKE_CUDA_TOOLKIT_INCLUDE_DIRECTORIES ON) 。我准备了一个small github project，它的结构与我的真实项目很接近。

错误消息：

error : namespace "std" has no member "filesystem"

解决方法

如here和here所述，这是cmake v3.18.2 或更小的已知漏洞，希望可以在cmake v3.18.3 中解决。 em>。

要解决此问题，我在CMakeLists.txt中添加了以下几行：

# hack for cuda before cmake 3.18.3
if(${CMAKE_VERSION} VERSION_LESS "3.18.3")
  target_compile_options(cuda_test_prog PRIVATE $<$<COMPILE_LANGUAGE:CUDA>:--std=c++17>)
endif()
