我正在尝试使用CLion作为IDE使用CUDA C ++启动项目。我安装了新版本的CUDA Developer Tools（v10.2），并尝试加载MakeFile的更改。显然，CUDA编译器（nvcc）无法正确链接，但是我不确定这是问题所在。
这是我的CMakeLists.txt：
cmake_minimum_required(VERSION 3.15)
project(test_cuda LANGUAGES CXX CUDA)
find_package(CUDA)
set(CMAKE_CXX_STANDARD 17)
add_executable(test_cuda main.cu)
我得到的结果如下：
"E:\Program Files\JetBrains\CLion 2019.2.5\bin\cmake\win\bin\cmake.exe" -DCMAKE_BUILD_TYPE=Debug -G "CodeBlocks - NMake Makefiles" <path_to_project>\test_cuda

用<path_to_project>替换项目文件夹的路径。
。cu文件目前只是一个简单的hello world源文件，因为我首先尝试使用CUDA编译器解决问题。
我真的找不到解决此问题的任何方法。
非常感谢。
消息module machine type 'x64' conflicts with target machine type 'X86'是问题的症结所在。这表明您有32位和64位体系结构不匹配。请确保使用consistent项目和编译器设置。
因此，如果要针对64位体系结构进行编译，请确保将项目（CMake）设置配置为构建x64目标。另外，您必须确保使用64位版本的编译工具（nvcc）。专门针对您的情况，您的链接器标志似乎包含/machine:X86，如果您打算使用64位构建，则需要将其删除。可以通过CLion IDE在您的[[Toolchain设置中进行配置。
