ubuntu vscode怎么配置g2o环境

### 配置 G2O 开发环境于 Ubuntu 上的 VSCode #### 安装依赖库 为了成功配置G2O环境，在Ubuntu上需先安装一系列必要的软件包。这包括但不限于`git`, `vim`, `cmake`, `gtk`, `libssl-dev`, 和 `libffi-dev`，这些工具对于构建和管理项目至关重要[^2]。 ```bash sudo apt-get update && sudo apt-get install git vim cmake gtk2.0 libssl-dev libffi-dev ``` #### 获取并编译 G2O 库源码 获取最新的G2O版本可以通过Git克隆官方仓库实现。之后进入解压后的目录执行CMake命令来完成本地化编译过程： ```bash git clone https://github.com/RainerKuemmerle/g2o.git cd g2o mkdir build && cd build cmake .. make -j$(nproc) sudo make install ``` #### 设置 C/C++ 扩展插件支持 为了让VSCode能够更好地理解C++代码结构以及提供智能感知功能，需要创建或编辑`.vscode/c_cpp_properties.json`文件以指定正确的编译器路径及其参数设置[^3]: ```json { "configurations": [ { "name": "Linux", "includePath": [ "${workspaceFolder}/**" ], "defines": [], "compilerPath": "/usr/bin/gcc", "cStandard": "gnu17", "cppStandard": "gnu++14", "intelliSenseMode": "gcc-x64" } ], "version": 4 } ``` #### 构建任务定义 (tasks.json) 接下来要做的就是编写一个用于自动化构建流程的任务描述文档(`.vscode/tasks.json`)，它会告诉IDE怎样调用外部程序来进行项目的编译工作[^4]: ```json { "version": "2.0.0", "tasks": [ { "label": "build_g2o_example", "type": "shell", "command": "cmake --build ./build --target all", "group": { "kind": "build", "isDefault": true }, "problemMatcher": ["$gcc"], "detail": "Generated task to compile the project." } ] } ``` #### 调试配置 (launch.json) 最后一步是准备调试方案(`.vscode/launch.json`)以便可以在开发过程中方便快捷地启动应用程序，并允许断点调试等功能: ```json { "version": "0.2.0", "configurations": [ { "name": "(gdb) Launch", "type": "cppdbg", "request": "launch", "program": "${workspaceFolder}/build/examples/simple_optimize", "args": [], "stopAtEntry": false, "cwd": "${fileDirname}", "environment": [], "externalConsole": false, "MIMode": "gdb", "setupCommands": [ { "description": "Enable pretty-printing for gdb", "text": "-enable-pretty-printing", "ignoreFailures": true } ], "preLaunchTask": "build_g2o_example", "miDebuggerPath": "/usr/bin/gdb", "logging": {"trace":true,"traceResponse":true}, "internalConsoleOptions": "openOnSessionStart" } ] } ```
