Segmentation Fault on when trying to construct QApplication

[tarahSky]

When I create a QtWidget application using QtCreator, and have exactly the same code. I can build and run it fine.

So it seems that the problem is with qmake when I try to compile it from the terminal.

If I create a project file called hello.pro using QtCreator, and have the file hello.cpp with the above code, if I build it using qmake, make (instead of QtCreator) it gives a segmentation fault.

But if I build it in QtCreator it will work fine.

Does anyone know why this may be occurring? Are there options that need to be specified to qmake or make?

Hi, I found the solution to the problem.

In my .bashrc I had the PATH variable as:

export PATH=$PATH:/opt/QtSDK/Desktop/Qt/474/gcc/bin:/opt/QtSDK/QtCreator/bin

instead of

export PATH=/opt/QtSDK/Desktop/Qt/474/gcc/bin:/opt/QtSDK/QtCreator/bin:$PATH

so it was using the version of qmake in /usr/bin which was for Qt 4.3.4

instead of the version in

/opt/QtSDK/Desktop/Qt/474/gcc/bin

which was for version Qt 4.7.4.

Once I changed it around, it accessed the right version of qmake, and worked fine.
