Qt和GLEW：程序退出，代码为-1073741515

Question

I an working with Qt and I am trying to switch from OpenGL 1.0 to a newer OpenGL by using GLEW. I have a GUi which uses a subclass of QGLWidget to process OpenGL stuff. At the beginning of initializeGL I do the statement GLenum err = glewInit(); and this causes the following:

program.exe exited with code -1073741515

Some more details: libs:

LIBS += -L"C:/Program Files/Microsoft SDKs/Kinect/v1.7/lib/amd64/" -lKinect10
LIBS += -lOpenGL32
LIBS += -lglew32
LIBS += -lglu32

Headers:

#include <windows.h>
#include <gl/glew.h>
#include <QByteArray>
#include <QGLWidget>
#include <memory>
#include <algorithm>

Full initializeGL() function:

void OpenGLWidget::initializeGL(){
    GLenum err = glewInit();
    if (GLEW_OK != err)
    {
      /* Problem: glewInit failed, something is seriously wrong. */

    }
    glEnable(GL_TEXTURE_2D); //Enables the drawing of 2D textures
    glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA8, width(), height(), 0, GL_BGRA_EXT, GL_UNSIGNED_BYTE, (GLvoid*) NULL);
    glBindTexture(GL_TEXTURE_2D, textureId); //Binds the GL_TEXTURE_2D to the textureId
    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST);
    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST);
    glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA8, width(), height(), 0, GL_BGRA_EXT, GL_UNSIGNED_BYTE, (GLvoid*) blackScreen); //Strart the program off with a black screen
    glBindTexture(GL_TEXTURE_2D, textureId); //Binds the GL_TEXTURE_2D to the textureId
    glClearColor(0,0,0,0);
    glClearDepth(1.0f);
}

What am I doing wrong?

• Does your version of Qt come with OpenGL support? Believe it or not, some don't. This was the case for me and it drove me crazy. Download a version of Qt with OpenGL support and replace the one you have. If all goes well you shouldn't have a problem.
• If you don't want to download a prebaked version, you must build Qt from scratch. This requires Python, Perl, possibly Ruby, and more than a little patience (because it's never as easy as the tutorials make you think).
• The error code you're getting seems to be a linking error that seems to have been solved here . Hopefully that solves it.
