Qt 5.0.1 and Ubuntu 12.04

RobBa85

Hello,

I have installed Qt on my Linux-System. Now I have the problem, that when I want execute one of the examples it comes the failure that he don't find the includes.

In the readme is written that I must add the "Include Path" to the tools search path for include files
and add the " lib path" to the search path for libaries.

Can someone please help me and show me the way to add this pathes. I found nothing where i can add these pathes.

Thank you very much

Robert

Install mesa packages or OpenGL drivers from your vendor.

sudo apt-get install libglu1-mesa

ok I have try it; The system says it is the newest Version of libglu1-mesa installed.

I think i must do the steps from the readme. I think this is the problem

But I don't find the place where i can add the pathes.

Original Readme text:

The Qt 5 installation program adds the installed Qt version
(<install_dir>/<version>/<compiler>/bin/qmake) to Qt Creator and creates a kit
that specifies the installed Qt version and compiler. To use the kit, add it for
your project in the Qt Creator Projects mode. Then select the kit in the Kit
selector before you build or run the project.

To compile C++ Qt applications by some other means, add
<install_dir>/<version>/<compiler>/include to your build tool's search path
for include files, and <install_dir>/<version>/<compiler>/lib to the search
path for libraries.
