Qt Creator，ptrace：不允许操作。什么是永久解决方案？ [英] Qt Creator, ptrace: Operation not permitted. What is the permanent solution?

问题描述

在调试Qt creator中的 C ++ 代码时，出现以下错误

While debugging C++ code in Qt creator I get the following error

ptrace: Operation not permitted.

Could not attach to the process. Make sure no other debugger traces this process.
Check the settings of
/proc/sys/kernel/yama/ptrace_scope
For more details, see /etc/sysctl.d/10-ptrace.conf

这里找到一个临时解决方案：尝试在QtProject中调试时接收错误

Here a temporary solution is found: Receiving error while trying to debug in QtProject

• 临时解决方案（重新启动后将无法生存）：

• temporary solution (won't survive a reboot):

echo 0 | sudo tee / proc / sys / kernel / yama / ptrace_scope

在终端中运行相同的代码每次当我启动我的电脑使用Qt。

But it is difficult to run the same code in terminal every time when I start my PC to use Qt.

What is the permanent solution for this?

推荐答案

• 转到具有root权限的位置 / etc 。

查找文件 rc.local 。

重新启动您的电脑，工作完美。

Restart your pc and you can see the debugger working perfectly.
