GDB断开，同时没有控制台输出

升级到Ubuntu 11.10后，我刚刚尝试调试我的C++程序，但我运行的gdb版本（7.3）似乎已损坏，无法进行调试输出。

发生了什么：

我点击调试，控制台窗口弹出，消息出现在顶部：

warning: GDB: failed to set controlling terminal: Operation not permitted

我没有从std:：cout调用中得到任何输出，甚至只是一个

std::cout << "hi" << std::endl;

有人能帮忙吗？我试着在谷歌上搜索这个主题，发现了很多类似的问题，但不是与这个特定症状有关的问题，以及如何解决它。我已经确保我有最新版本的GDB等

附录：我使用代码：：块作为我的ide。

用完整的命令行输出重建我的项目给出：
