2024/07/05更新

安裝C/C++、CMake 、CMake Tools extension
C/C++的IntelliSense直接選compile_commands.json

       libgstrtspserver-1.0-dev libx11-dev libjson-glib-dev libyaml-cpp-dev

Setup VSCode for development

  • install VSCode extension
    CodeLLDB、clangd 、CMake 、CMake Tools

  • Note: Do not install C/C++ extension pack from Microsoft

  • copy deepstream-test5 to your workspace
    deepstream-test5 is a complete example to modify deepstream-app，this will take the advantage of the module design of deepstream-app. You can add probe to customize the app. It have good config parser and error handling, those will save many effort.
    Following our workspace is in the copy of deepstream-test5 folder.

1
cp -r /opt/nvidia/deepstream/deepstream/apps/sample_apps/deepstream-test5/* /path/to/your/workspace
  • create launch.json and task.json
    create launch.json and task.json for compile and debug

tasks.json use CMake to build

        }

}

    // Use IntelliSense to learn about possible attributes.

    "version": "0.2.0",
    "configurations": [
        {
            "type": "lldb",
            "request": "launch",
            "name": "Debug",
            "program": "${workspaceFolder}/deepstream-test5",//the path of the executable file deepstream-test5
            "args": ["-c", "configs/test5_config_file_src_infer.txt"],//arg for deepstream-test5
            "cwd": "${workspaceFolder}",//指定工作目錄
            "preLaunchTask": "CMake: build"
        }
    ]
}
```  


create settings.json for clangd to read compile_commands.json. clangd can generate code navigator.
```json
{
    "cmake.sourceDirectory": "${workspaceFolder}",
    "cmake.generator": "Unix Makefiles",
    "clangd.arguments": [
        "--compile-commands-dir=${workspaceFolder}/build",
        "--background-index",
        "-j=8",
        "--query-driver=/usr/bin/clang++",
        "--clang-tidy",
        "--clang-tidy-checks=performance-*,bugprone-*",
        "--all-scopes-completion",
        "--completion-style=detailed",
        "--function-arg-placeholders",
        "--header-insertion=iwyu",
        "--pch-storage=memory",
    ],
}
  • Create CMAKELists.txt
    Create CMakeLists.txt under the workspace folder, CMake will help you find CUDA and nvcc, no more CUDA_VER env variable needed even in jetson.
    In this example，we need to compile deepstream-app first and use the object file in our project.So we use ExternalProject_Add to do this.

We need to change the permission for deepstream-app source folder in order to compile the deepstream-app.
