调试C++；在MacOS上使用Bazel构建代码时不起作用 我在VisualStudio代码中用BaZelBug系统启动了一个C++项目。但是，当二进制文件是使用Bazel构建时，调试在IDE中不起作用

使用

clang++-g main.cpp-o sample构建应用程序时，我可以调试该应用程序

我的设置：
操作系统：MacOS，Bazel:release 0.17.2-homebrew，VS代码：1.27.2

这是由Bazel的编译方式造成的。是否有任何解决方法使调试工作正常

这里是一个最小的例子。只需在编辑器中放置一个断点，运行调试，并观察未命中的断点：

Upd。一,

已尝试调试bazel生成的可执行文件并直接使用lldb手动生成：

Bazel构建的二进制文件
Bazel构建--编译模式=dbg示例

lldb bazel-bin/sample
(lldb) breakpoint set -n main
Breakpoint 1: 13 locations.
(lldb) r
Process 24391 stopped
* thread #1, queue = 'com.apple.main-thread', stop reason = breakpoint 1.1
    frame #0: 0x00000001000021b0 sample`main
sample`main:
->  0x1000021b0 <+0>: pushq  %rbp
    0x1000021b1 <+1>: movq   %rsp, %rbp
    0x1000021b4 <+4>: subq   $0x20, %rsp

   2    
   3    int main() {
-> 4        std::cout << "tests" << std::endl;
   5        return 0;
   6    }
Target 0: (sample) stopped.

在可执行文件中查找“调试注释”后（感谢）

我发现这些路径指向Bazel用来构建的沙箱环境。而且这条路已经无法通行了

这可能是由Bazel的已知问题引起的


Upd。二,

将Bazel更新到版本0.17.2（问题已经解决）后，此问题仍然存在


Upd。三,

最后，它变成了巴泽尔问题。我在这里创建了一个问题（升级更新以获得答案）：看起来像是一个已知的问题：
如果您扔掉visual studio代码，您肯定会有更好的运气构建和/或获得答案。从命令行运行bazel，并向我们展示该命令，这样我们就知道它实际上是如何执行的。另外，请告诉我们您在让bazel使用对调试有用的编译选项方面做了什么。@Mark我已将pure bazel命令添加到更新的部件中，所以实际问题是您没有调试符号？你说它“不起作用”，但在我看来，你可以很好地附加，尽管没有符号。@BradAllred我可以附加调试器，尽管问题是IDE中的调试不起作用。在你的帖子中，我完全不清楚“不起作用”。您根本没有提供错误。
