glClipPlanef is only implemented in your OpenGL driver,
if the extension support one of: GL_VERSION_ES_CM, GL_IMG_user_clip_plane,
GL_OES_single_precision extension.

That is what I tried to explain earlier.

/** Entry point to C language function: <code> void {@native
glClipPlanef}(GLenum plane, const GLfloat *  equation) </code> <br>Part of
<code>GL_VERSION_ES_CM</code>, <code>GL_IMG_user_clip_plane</code>,
<code>GL_OES_single_precision</code><br>Alias for:
<code>glClipPlanefIMG</code>, <code>glClipPlanefOES</code>
      @param equation a direct or array-backed {@link java.nio.FloatBuffer}   */
  public void glClipPlanef(int plane, FloatBuffer equation);
