Debugger issue on CentOS.

AlfaromeoCorse

Please give me advice about debugging on CentOS6.8.

When I tried debugging by Qt Creator but debugger didn't work correctly as following conditions.
I set breakpoints, but debugger was terminated without stopping at breakpoint.

OS: CentOS6.8 x86_64
Qt5.6.1 Qt Creator4.0.3

GDB7.12
Python2.7

Thanks.

Did the program run correctly?
What's the linux kernel version for that distro?

It is OK about program running mode, that's problem is only debug mode.
Kernel: 2.6.32-642.13.1.el6.x86_64
CentOS6.8 64bit

Thank you.

@AlfaromeoCorse Does GDB work? Did you try to start it manually and debug a program?

Please teach me how to start it manually..
I made new Kit and change debugger setting.

@AlfaromeoCorse enter gdb in a terminal window
enter: file PATH_TO_EXECUTABLE
then enter: run

I tried it. Following result means GDB doesn't work?

@AlfaromeoCorse If it does not terminate/crash then it should be OK, but not sure about those Python exception though.

@jsulm Thank you for your kindness! I uninstall gdb once, and reinstall. This issue was solved.
