从命令行正常运行时，为什么gdb在eclipse中不起作用？ [英] Why is gdb not working in eclipse when it is working fine from command line?

问题描述

我已经使用eclipse为Linux创建并成功编译了一个C ++应用程序。当我从命令行调试它时，一切工作都很好，我可以进行调试。

I have created and successfully compiled a C++ application for Linux using eclipse. When I debug it from the command line everything works perfect, I can debug just fine.

但是我需要在eclipse中调试，因为它更方便和容易。我配置了调试会话，并尝试启动它时出现错误：

But I require debugging in eclipse because is more convenient and easy. I configure the debug session and when trying to launch it I get the error:

Error in final launch sequence
Failed to execute MI command:
-exec-run
Error message from debugger back end:
Warning:\nCannot insert breakpoint 1.\nCannot access memory at address 0x1fff82e8\nCannot insert breakpoint 2.\nCannot access memory at address 0x80001ea4\n
Warning:\nCannot insert breakpoint 1.\nCannot access memory at address 0x1fff82e8\nCannot insert breakpoint 2.\nCannot access memory at address 0x80001ea4\n

但是我不知道为什么会收到该错误，尤其是因为gdb在我从cmd执行它。

But I have no idea why I am getting that error, especially because gdb is working fine when I execute it from cmd.

这些是我在Eclipse中的c ++编译器标志：

These are my c++ compiler flags in eclipse:

-std=c++98 -O0 -g3 -Wall -c -fmessage-length=0

在创建项目时，我选择了 Hello world C ++项目和 Linux GCC作为工具链。

When creating the project I chose the "Hello world C++ Project" and the "Linux GCC" as the toolchain.

我正在使用以下版本的GDB和Eclipse：

I'm working with the following versions of GDB and Eclipse:

• Eclipse Neon.1a版本（4.6.1）


• GNU gdb（Ubuntu 7.11.1-0ubuntu1〜16.04）7.11.1

推荐答案

我可以重现此问题的唯一方法是启用地址断点。就我而言，这是CDT中的错误，但与此同时，一种解决方法是从 Breakpoints 视图中删除或禁用任何地址断点。

The only way I can reproduce this problem is to have address breakpoints enabled. As far as I am concerned this is a bug in CDT, but in the meantime as a workaround remove or disable any address breakpoints from the Breakpoints view.

我已提交臭虫509894 来跟踪CDT中的问题

I have submitted Bug 509894 to track the issue in CDT.
