QT5.7 problem building examples and more with qtcreator

[gig-raf]

Hi all,

hope someone can please give me a hint here. I am stuck :-(

I am running Qt5.7 on Ubuntu 14.04 (64bit) in a virtualbox.




which qtcreator
/usr/bin/qtcreator

qtcreator -version

Qt Creator 3.0.1 based on Qt 5.2.1
...


and my qmake -query gives me



qmake -query

now if I open qtcreator and compile one of the many examples (fails with all of the ones I have tried.....and i have tried a lot)

I get

the stuff with openGL I guess are not critical, but the last line is bad..


I guess/hope that the problem is just a configuration problem inside qtcreator.

I have configured my kit to use the qmake in the /gcc_64/bin

the gcc that is being used now is the gcc in /usr/bin/gcc-4.8



/usr/bin/gcc-4.8 --version
gcc-4.8 (Ubuntu 4.8.5-2ubuntu1~14.04.1) 4.8.5

can anybody advice me here?

I think the problem might be that your mesa library (which implements OpenGL on linux) might be old. You could try to update or switch to a different OpenGL implementation.
