Compile/Running in terminal and keep getting same error - Ubuntu 14.04
-
Hey guys,
I keep trying to compile in Terminal but am running into the same error. It says that <QGLWidget> doesnt exist. I have added QtOpenGl to my header, as well as my main.cpp. I have added the proper command to the .pro file, and added an INCLUDEPATH to the actual qt project itself. But I still end up with the exact same error. Below is my command in Terminal, and then its response:sam@sam-VirtualBox:~/Downloads$ "/home/sam/Downloads/qt-everywhere-opensource-src-4.8.5/bin/qmake" '/home/sam/Qt5.0.2/5.0.2/gcc/examples/opengl/2dpainting/2dpainting.pro' -r CONFIG+=debug -spec /home/sam/Downloads/qt-everywhere-opensource-src-4.8.5/mkspecs/qws/linux-arm-gnueabi-g++

Hi,
To add to @Joel-Bodenmann, watch out, you are trying to build Qt 5 examples with Qt 4. Not that it's not possible but you may have surprises.
