Can't Use OpenGL ES 2.0 identifiers

[Ferobles92]

Hello all,

I have picked up a book on OpenGL ES 2.0 in order to learn its details. In doing so, I have found debugging code in the book that I can't use on Qt. The debugging code uses identifiers such as GL_SHADER_COMPILER, GL_NUM_SHADER_BINARY_FORMATS, GL_SHADER_BINARY_FORMATS, etc...

Qt Designer will even open up the drop-down menu for me to select these identifiers. However, when I build the program I get "use of undeclared identifier ... "

Here is the kicker: during my draw code, I can use GL_TRIANGLES just fine.

Here is a list of all includes I have I think would include those identifiers:

#include <QCoreApplication>
#include <QScreen>
#include <QPainter>
#include <qopengl.h>
#include <QOpenGLContext>
#include <QOpenGLPaintDevice>
#include <QOpenGLShaderProgram>
#include <QWindow>
#include <QOpenGLFunctions>

Now, this identifiers are not imperative, but they would be nice to have in order to write some debugging code of my own. What I am trying to do is find out is the format of my shader compiler, and the book's sample code uses these identifiers.

What am I missing to use those identifiers???

Thanks in advance.
