C++ 断点不存在'；调试C+时无法工作+；与Bazel一起在macOS high sierra建造的项目

系统详细信息

• 操作系统和版本：macOS high sierra 10.13.4
• VS代码版本：1.25.1
• C/C++扩展版本：0.17.7
• 已安装其他扩展
  • bazel:0.10.0-自制
  • lldb:lldb-902.0.79.2
  • gdb:GNUGDB（gdb）8.0.1

错误描述

我使用BAZEL来构建一个教程C++项目。源代码非常简单，如下：

#include <iostream>
#include <string>

using namespace std;

void greet(const string& person) {
    cout << "Hello, " << person << "!" << endl;
}

int main(int argc, char** argv) {
    if(argc >= 2) {
        greet(argv[1]);
    } else {
        int x = 0;
        int y = 0;
        int c;
        c = x * y;
        cerr << "insufficient args, usage: " << argv[0] << " personNameHere" << endl;
    }
    return 0;
}

在

${workspaceFolder}/bazel out/darwin dbg/bin/hello/main

然后在vs代码中使用lldb进行调试。假设我在第11行设置了一个调试标志，它是

intmain（intargc，char**argv）{

My launch.json描述如下：

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "(lldb) Launch",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceFolder}/bazel-out/darwin-dbg/bin/hello/main",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": true,
            "MIMode": "lldb"
        }
    ]
}

然后我按下调试面板中的调试按钮。 然而，它从不停在第11行。所有调试标记都变成灰色，当我将鼠标悬停在上面时，它会告诉我：“未检查的断点”

vs代码终端输出结果如下所示：

在由vs代码启动的运行终端中，程序似乎运行良好，没有中断：

我注意到bazel需要像我一样设置build-cdbg--strip=从不支持调试。 同时，我尝试在terminal中运行lldb，它似乎运行得很好。输出如下所示：

我是否犯了一些错误或滥用了bazel或vs代码？ 或者任何人都可以在vscode中提供一个可以调试bazel项目的配置json？
