Question

我刚刚尝试在升级到Ubuntu 11.10之后调试我的C ++程序，看来我正在运行的gdb版本（7.3）因调试输出而中断。

会发生什么：

我点击调试，弹出控制台窗口，消息显示在顶部：

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

我没有得到std :: cout调用的输出，即使只是

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

任何人都可以提供帮助吗？我试图谷歌这个主题，并提出了很多类似的问题，但没有与这个特定症状相关的问题，以及如何解决它。我已经确定我有最新版本的GDB等。

附录：我使用Code :: Blocks作为我的想法。

使用完整的命令行输出重建我的项目会给出：

我找到了答案 - 由于某种原因，C :: B没有将global -g设置为默认值，所以我没有调试符号。我仍然得到奇怪的错误消息，但至少我现在得到控制台输出：）

调试时GDB坏了 - 没有控制台输出？
