Qt application exit with segmentation fault

Hi,

I am using Qt 4.7.1. I compiled it with buildroot. 

If I run the Qt application without -qws option, I got the following error
message:
QWSSocket::connectToLocalFile could not connect:: Connection refused

If I run with -qws option, everything seems OK. I can run mousecalibration
and all the demos as well as examples.

My problem is when I quit the qt application, I always receive a
"Segmentation fault" message.

Can any one have solution for this issue?

My configuration is:


export TSLIB_TSEVENTTYPE=INPUT
export TSLIB_CONSOLEDEVICE=none
export TSLIB_FBDEVICE=/dev/fb0
export TSLIB_TSDEVICE=/dev/input/ts
export TSLIB_CALIBFILE=/etc/pointercal
export TSLIB_CONFFILE=/etc/ts.conf
export TSLIB_PLUGINDIR=/usr/lib/ts
export LD_LIBRARY_PATH=/usr/lib
export QWS_MOUSE_PROTO=tslib:/dev/input/ts
export QWS_DISPLAY=LinuxFB:mmWidth=310:mmHeight=190

All the path are correct.

Thank you very much

Bao

I have the same problem.

I found answer here http://bugreports.qt.nokia.com/browse/QTBUG-7564
It is in QVariantAnimation::registerInterpolator.
"Instrumenting the code shows that the static destructor for the variable
registeredInterpolators is being called in incorrect order. Specifically,
registeredInterpolators exists in libQtCore and is destroyed before
libQtGui has completed unloading.
Suggest fixing this with a simple

if (!interpolators)
return;"

Hi Leo,

Thank for your reply.

Where can I put those line into? When I put that to main.cpp, I got the
error when compiling:
main.cpp:51: error: 'interpolators' was not declared in this scope
main.cpp:52: error: return-statement with no value, in function returning
'int'
