QOpenGLShaderProgram: could not create shader program

[vladinko0]

I don't know, what additional information you need?

This error regards all kinds of Qt projects. I am using HP Compaq dc7800p Small Form Fader, Windows Vista Business 32 bit, DirectX 11, Intel Q35 Express Chipset Family Graphic driver.

Please, specify, what else you need?

[A Former User]

Please give a minimal but complete example so that one can try to reproduce the problem.

[vladinko0]

It regards all projects. For example "Hello World" program.

Ah, now I understand. So you're not tinkering with QOpenGLShaderProgram yourself at all, right?

[vladinko0]

Yes, You are right.

@vladinko0 If your Qt version isn't OpenGL-only, then you can force your program to use ANGLE:
QCoreApplication::setAttribute( Qt::AA_UseOpenGLES ); // use DirectX via ANGLE

[vladinko0]

I installed Qt 5.4.1 MinGW 4.9.1 (32 bit), OpenGL for Windows .

According to Intel documentation the Q35 Express chipset only supports OpenGL 1.3. That's waaay to low for Qt.

You can run the ANGLE (or dynamic) version of Qt (OpenGL layer on top of DirectX). It's the package without "OpenGL" in the name mentioned by @Wieland. This still won't let you run some of the OpenGL examples. It's high time for an upgrade ;)

Is it possible to put this line into Qt Quick UI project?
Because there are only qml files like this:
import QtQuick 2.4
import QtQuick.Controls 1.3
import QtQuick.Window 2.2
import QtQuick.Dialogs 1.2

ApplicationWindow {
title: qsTr("Hello World")
width: 640
height: 480

menuBar: MenuBar {
    Menu {
        title: qsTr("&File")
        MenuItem {
            text: qsTr("&Open")
            onTriggered: messageDialog.show(qsTr("Open action triggered"));
        }
        MenuItem {
            text: qsTr("E&xit")
            onTriggered: Qt.quit();
        }
    }
}

MainForm {
    anchors.fill: parent
    button1.onClicked: messageDialog.show(qsTr("Button 1 pressed"))
    button2.onClicked: messageDialog.show(qsTr("Button 2 pressed"))
    button3.onClicked: messageDialog.show(qsTr("Button 3 pressed"))
}

MessageDialog {
    id: messageDialog
    title: qsTr("May I have your attention, please?")

    function show(caption) {
        messageDialog.text = caption;
        messageDialog.open();
    }
}

}

Or where to put this line?

@vladinko0 It belongs in your main.cpp:

int main(int argc, char *argv[])
{
    // Options on Windows; set before instantiating QApplication
    // QCoreApplication::setAttribute( Qt::AA_UseOpenGLES ); // use DirectX via ANGLE
    
    QApplication app( argc, argv );

[vladinko0]

@Wieland But Qt Quick UI project has no main.cpp file.

[A Former User]

@vladinko0 I know. Can't you use Qt Quick Application?

[vladinko0]

@Wieland Yes, I used also Qt Quick Application project with the same error.

[A Former User]

Hmm. If you have an ANGLE capable Qt version and set the Qt::AA_UseOpenGLES attribute and it still doesn't work then I don't know. Sorry :-(

[boumath]

I had exactly the same issue with Qt 5.4.1 MinGW 32-bit

@Wieland solution to force ANGLE is the good one, but it doesn't work. In fact I'm not sure this version support it. If you look into the \Qt5.4.1\5.4\mingw491_32\bin directory you will not find libEGL.dll, libGLESv2.dll and d3dcompiler_47.dll. I used to work with ANGLE but with Microsoft Visual Studio 2013 compilator, and these libraries are provided in the Qt distribution : "Qt 5.4.1 for Windows 32-bit (VS 2013, 705 MB)"

@Wieland do you have MinGW or VS2013 compilator ?

[A Former User]

@boumath Hi, I use VS 2013.

[boumath]

Thanks Wieland, that's explains why forcing ANGLE in your case is working and not for vladinko0

@vladinko0, I suggest you to install Visual Studio 2013 (Express is free), and install Qt 5.4.1 for VS2013. Force Qt::AA_UseOpenGLES like Wieland says. Because your graphic chipset is old, perhaps you will need to set the environment variable QT_ANGLE_PLATFORM to d3d9 (if it doesn't support DirectX 11).

[vladinko0]

@boumath I tried VS2013 with Qt 5.5 .0 but no success. :(

Hi,

If you are still on the same machine the message from Chris:

Is still valid
