在升级到 Ubuntu 11.10 后,我刚刚尝试调试我的 C++ 程序,我正在运行的 gdb 版本 (7.3) 似乎无法用于调试输出。
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,即使只是一个
std::cout << "hi" << std::endl;
有人能帮忙吗?我试着用谷歌搜索这个主题并提出了很多类似的问题,但不是与这个特定症状相关的问题,也没有解决它的方法。我已经确保我拥有最新版本的 GDB 等。
附录:我正在使用 Code::Blocks 作为我的想法。
用完整的命令行输出重建我的项目给出:

如果这有帮助?...
最佳答案
我找到了答案 - 由于某些原因 C::B 没有将全局 -g 设置为默认值,所以我没有调试符号。我仍然收到奇怪的错误消息,但至少我现在得到了控制台输出:)
关于c++ - GDB 在调试时损坏 - 没有控制台输出?,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/9199279/
