mac gdb SIG113

 

mac自从升级至Sierra系统后，gdb调试程序后出错：

 

During startup program terminated with signal SIG113, Real-time event 113

网上方案：升级gdb，修改gdb配置：

brew upgrade gdb
cat "set startup-with-shell off" > ~/.gdbinit

 该方案只适合v12.10.2及以下版本，v10.12.6依然无法工作。

 

上述错误是由于mac的安全保护策略所致，阻止gdb调试程序。网上提出可使用lldb调试，毕竟是苹果自家的产品，亲测可行，命令与gdb基本一致。
