error: 'QOpenGLFunctions_3_2_Core' does not name a type

[jmjoy]

The error log is:

build/src/frontend/qt_sdl/melonDS_autogen/EWIEGA46WW/moc_main.cpp:527:29: error: 'QOpenGLFunctions_3_2_Core' does not name a type; did you mean 'QOpenGLFunctionsPrivate'?
         return static_cast< QOpenGLFunctions_3_2_Core*>(this);
                             ^~~~~~~~~~~~~~~~~~~~~~~~~
                             QOpenGLFunctionsPrivate

It doesn't seem to support my device, because I found in QtGui/qopenglfunctions_3_2_core.h:

#if !defined(QT_NO_OPENGL) && !defined(QT_OPENGL_ES_2)

#include <QtGui/QOpenGLVersionFunctions>
#include <QtGui/qopenglcontext.h>

QT_BEGIN_NAMESPACE

class Q_GUI_EXPORT QOpenGLFunctions_3_2_Core : public QAbstractOpenGLFunctions
{
// ...
}

And my device's SDK:
