How to get the file: GL/gl.h



  • Hi,everyone,

    the error is shown as:
    ~/Desktop/Qt/4.8.1/gcc/include/QtOpenGL/qgl.h:88: error:GL/gl.h: No such file or directory

    How to fix it?

    Thank a lot!



  • Install the development packages of OpenGL for your distribution. This will usually install the needed headers into /usr/include/GL but it may very between distros.



  • I Installed the development packages of OpenGL,and the problem was solved, but another error occurs:

    'gluPerspective' was not declared in this scope

    what's the matter?

    Thanks a lot!



  • Thanks very much .

    error from : make&install libmeegotouch
    process : sudo aptitude/ apt-get install freeglut3/libgl1-mesa-dev
    but failed
    solutions :install the Synaptic Package Manager
    then install the libgl1-mesa-dev and related dependencies



  • You probably need additional utility packages for OpenGL such as GLU, GLUT, GLEW.
