Compiling error: cannot find -lGLU and -lGL in kubuntu linux

Question

I have some problems with compiling "hello world" application in kubuntu linux 11.10. This is project file:

// opengltext.pro
SOURCES += \
    main.cpp
QT += opengl

And one cpp file:

    // main.cpp

    #include <QApplication>

    int main( int argc, char *argv[] )
    {
        QApplication app( argc, argv );
        return app.exec();
    }

i have got the following errors:

:-1: error: cannot find -lGLU
:-1: error: cannot find -lGL
:-1: error: collect2: ld returned 1 exit status

I try find in google the solution of this problem. But didn't find. i try to install:

sudo apt-get install libglw1-mesa-dev

but this error is still taking place

What's the problem?

Solution

You need the following 2 packages:

xlibmesa-gl-dev
xlibmesa-glu-dev

-- edit --

Thanks for correction @ephemient, these were obsolete names, right names are:

libgl1-mesa-dev
libglu1-mesa-dev

If your system reports that you already have the packages and it still isn't working, try reinstalling them via your package manager. I already the packages installed, but for some reason I was missing the required libGL.so files. Reinstalling fixed the problem.

Thanks pR0Ps - reinstalling worked for me to: aptitude reinstall libgl1-mesa-dev
