Qt 5.2.1 + QtCreator 3.0.1
设置断点，点击调试运行时报如下错误
“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”
解决方法：
echo 0 | sudo tee /proc/sys/kernel/yama/ptrace_scope
