Kernel/Qtimer.cpp: No such file or directory

[Madesh]

Hi All,

I'm using Qt 4.8 version where I have made use of Qtimer . During compilation the code snippet compiles fine but during run time , the application comes to an abrupt end displaying the following message.

Program received signal SigSEGV, Segmentation fault.

QTimer::start(this=0x0) at kernel/qtimer.cpp:215
215 kernel/qtimer.cpp: No such file or directory.
Please help.

Thanks & Regards,
Madesh

What does it do in the supported version, Qt5.x?

@Kent-Dorfman

Thanks for replying.
It's working fine in Qt 5.X.

4 isn't supported anymore. Also, getting help in this forum, the "upgrade to a supported version" answer will be very common when asking about problems in legacy versions.

I do understand that I should upgrade to the latest version , however, I'm working on a legacy application, upgrading right now is a huge task , given the limited time frame.

@Madesh said in Kernel/Qtimer.cpp: No such file or directory:

QTimer::start(this=0x0)

You have this == 0. That's a problem, no matter what library you're using.

Do some debugging; find out why the program is trying to call the start() method on a nullptr.

Hi, Thanks for replying .

I debugged code and found out that , timer is created on some condition in constructor. If that condition was not met, the timer is not created. So i was getting segmentation fault error.This issue is resolved now.
Thanks a lot.
