ubuntu12.10(64bit)下使用Qt Creator 5.1.1編寫c/c++程序,在控制檯程序調試的時候出現如下的問題:
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
解決辦法是在終端輸入:sudo gedit /etc/sysctl.d/10-ptrace.conf
把其中的kernel.yama.ptrace_scope = 1 改爲 kernel.yama.ptrace_scope = 0
然後重啓。
