QGLShaderProgram works on Debug mode, fails on running in Release.

Would you click Projects and see whether "Shadow Build" is ticked. If it is, remove it. Now build again and run in release mode.

That's even more strange... if I disable Shadow Build it doesn't run:

The program has unexpectedly finished. ...Test3.exe exited with code -1073741515

Edit: I found that this means that is missing some libs, it happens since disabling shadow build it is placed in another directory, after putting that dlls there I have the same "bool __thiscall QGLShaderPrivate::create(void): Could not create shader of type" error.

So that didn't solve nothing but thank you for your time anyway.

Would you upload your shader programs in a different way. Add vertext.sh and fragment.sh to your src. Then try linking them this way as below:

//#version 130
 
precision mediump float;
 
uniform mat4 mvpMatrix;
 
attribute vec4 vertex;
attribute float color;
 
varying float varyingColor;
 
void main(void)
{
    varyingColor = color;
    gl_Position = mvpMatrix * vertex;
}

//#version 130

precision mediump float;

uniform mat4 mvpMatrix;

attribute vec4 vertex;
attribute float color;

varying float varyingColor;

void main(void)
{
    varyingColor = color;
    gl_Position = mvpMatrix * vertex;
}

To copy to clipboard, switch view to plain text mode 

fragment shader has the same format, you know it. Then do this in the code:

initCommon();
 
    shaderProgram.addShaderFromSourceFile(QGLShader::Vertex, ":/vertexShader.vsh");
 
    shaderProgram.addShaderFromSourceFile(QGLShader::Fragment, ":/fragmentShader.fsh");
 
    if(!shaderProgram.link())
    {
        exit(1);
    }

initCommon();

    shaderProgram.addShaderFromSourceFile(QGLShader::Vertex, ":/vertexShader.vsh");

    shaderProgram.addShaderFromSourceFile(QGLShader::Fragment, ":/fragmentShader.fsh");

    if(!shaderProgram.link())
    {
        exit(1);
    }

To copy to clipboard, switch view to plain text mode 

initCommon() is:

void GlWidget::initCommon()
{
    //qglClearColor(QColor(Qt::black));
    glEnable(GL_DEPTH_TEST);
    glEnable(GL_CULL_FACE);
 
    glEnable(GL_BLEND);
    glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);
}

void GlWidget::initCommon()
{
    //qglClearColor(QColor(Qt::black));
    glEnable(GL_DEPTH_TEST);
    glEnable(GL_CULL_FACE);

    glEnable(GL_BLEND);
    glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);
}

To copy to clipboard, switch view to plain text mode 

check this method and let us know about the result.

PS: don't forget to upload your shaders to your resources.

No luck, also I tried to load from "./a.vert" "./a.frag" it founds the files but they aren't created properly.



It looks that the problem is during the compilation not on loading.

compileSourceCode(code) doesn't work neither on Release but works on Debug.

I fixed it... just by updating to Qt 5.1.1
