使用Mason.nvim配置Neovim的nvim-dap调试C++时遇退出码-1求助

nvim-dap无法在Neovim环境中正常工作，启动调试后始终以退出码-1终止。已在多个可正常运行的程序上测试，程序本身无调试问题；终端中单独运行lldb正常，排除权限问题。希望通过mason-nvim-dap提升配置可移植性，当前相关配置如下：

插件安装配置 #

-- DAP Installs
{
    "rcarriga/nvim-dap-ui",
    event = "VeryLazy",
    dependencies = "mfussenegger/nvim-dap",
    config = function()
      local dap = require("dap")
      local dapui = require("dapui")
      dapui.setup()
      dap.listeners.after.event_initialized["dapui_config"] = function()
        dapui.open()
      end
      -- dap.listeners.before.event_terminated["dapui_config"] = function()
      --   dapui.close()
      -- end
      -- dap.listeners.before.event_exited["dapui_config"] = function()
      --   dapui.close()
      -- end
    end
  },
  {
    "jay-babu/mason-nvim-dap.nvim",
    event = "VeryLazy",
    dependencies = {
      "williamboman/mason.nvim",
      "mfussenegger/nvim-dap",
    },
    opts = {
      handlers = {}
    },
  },
  {
    "mfussenegger/nvim-dap",
    vim.keymap.set('n', '<leader>Dc', ':lua require"dap".continue()<CR>', {desc = '[d]ebug [c]ontinue'}),
  },

DAP核心配置 #

-- DAP config
require("mason").setup()
require("mason-nvim-dap").setup({
  ensure_installed = {'codelldb'},
  automatic_installation = true,
})

调试输出信息 #

• DAP-REPL控制台：

  Console is in 'commands' mode, prefix expressions with '?'.
  Launching: /Users/myname/Documents/code/400hw/ec3
  Launched process 15338
  Process exited with code -1.

• DAP终端：

  [Process Exited 0]

• 1. 补充codelldb调试适配器与语言配置
  mason-nvim-dap默认会注册codelldb适配器，但空handlers可能导致配置未生效。在DAP配置中添加以下代码，明确适配器路径与C/C++调试启动项：

  local dap = require("dap")
  -- 配置codelldb适配器
  dap.adapters.codelldb = {
    type = 'server',
    port = "${port}",
    executable = {
      command = vim.fn.stdpath("data") .. "/mason/packages/codelldb/extension/adapter/codelldb",
      args = {"--port", "${port}"},
    }
  }
  
  -- 配置C/C++调试启动规则
  dap.configurations.cpp = {
    {
      name = "Launch file",
      type = "codelldb",
      request = "launch",
      program = function()
        return vim.fn.input('Path to executable: ', vim.fn.getcwd() .. '/', 'file')
      end,
      cwd = '${workspaceFolder}',
      stopOnEntry = false,
    },
  }
  -- 让C语言复用C++的调试配置
  dap.configurations.c = dap.configurations.cpp
  

• 2. 确保编译时添加调试符号
  编译程序必须加上-g参数生成带调试信息的可执行文件，否则调试器无法附着。示例编译命令：

  gcc -g your_program.c -o your_program
  

• 3. 验证codelldb安装状态
  运行:Mason命令，确认codelldb已成功安装。若安装失败，手动触发重新安装，或检查网络连接状态。

• 4. 恢复DAP-UI的退出监听
  取消注释关闭UI的监听代码，避免UI状态异常干扰调试流程：

  dap.listeners.before.event_terminated["dapui_config"] = function()
    dapui.close()
  end
  dap.listeners.before.event_exited["dapui_config"] = function()
    dapui.close()
  end
  

• 5. 检查codelldb可执行路径有效性
  手动执行以下命令，确认codelldb可正常启动：

  ~/.local/share/nvim/mason/packages/codelldb/extension/adapter/codelldb --version
  

  若路径不存在，说明mason安装失败，需重新安装codelldb。
