Solved: Qt Creator doesn’t debug a non-Qt project
I just started using Qt Creator in Ubuntu via a VM on Windows. I created a plain non-Qt C project using the Creator. When I tried to debug the project, I got an error message describing a prblem as below:
“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”
The system environment is set as below:
Native OS: Windows 7 (64 bit)
Qt: 4.8.3 (64 bit)
Compiler: GCC (x86 64 bit)
Debugger: GDB 7.4-2012.04, configured as x86_64-linux-gnu
The program was built and run properly without debugging mode.
I look forward to any hints/ideas on how to fix the the problem.
Thanks in advance.
Just found that this is actually an issue of Qt Creator with Ubuntu of versions later than 10.10. Go https://bugreports.qt-project.org/browse/QTCREATORBUG-3509 to find a workaround to the problem.
