解决vscode在win下使用cuda无法跳转库函数的问题

安装相关插件

在项目下的.vscode文件夹中正确配置版本和相关文件的路径，有些路径需要根据你电脑中的实际路径进行配置，如果某个路径有标黄的波浪线，说明vscode没有找到这个路径

c_cpp_properties.json

settings.json（这个文件非常重要，如果没有，基本没法跳转）

复制代码

{
    "C_Cpp.default.includePath": [
        "C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v12.4/include",
        "C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v12.4/include/cublas",

        "*.cuh": "cpp",
        "cuda_runtime.h": "cpp",
        "cublas*.h": "cpp"
    }
}

tasks.json，这个文件的配置根据自己的实际情况决定，不需要跟我的一样

复制代码

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "build",
            "type": "shell",
            "command": "C:\\Program Files\\NVIDIA GPU Computing Toolkit\\CUDA\\v12.4\\bin\\nvcc.exe",
            "args": [
                "${workspaceFolder}/main.cu",
                "-o",
                "${workspaceFolder}/main.exe",
                "-arch=sm_60",

                "-std=c++17"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "problemMatcher": ["$nvcc"],
            "detail": "使用nvcc编译CUDA程序"
        },
        {
            "label": "run CUDA",
            "type": "shell",
            "command": "${fileDirname}\\${fileBasenameNoExtension}.exe",
            "dependsOn": "build",
            "group": {
                "kind": "test",
                "isDefault": true
            },
            "problemMatcher": []
        },
        {
            "label": "clean",
            "type": "shell",
            "command": "del",
            "args": [
                "${workspaceFolder}\\main.exe",  
                "/f",
                "/q"
            ],
            "problemMatcher": []
        }
    ]
}

配置好之后就可以正确跳转了
