qt - 错误 : QOpenGLShader: could not create shader - when compiling QtQuick applications with Qt5. 2 Mingw OpenGL

Question

我已经下载并安装了“Qt 5.2 mingw(opengl 和 x86)”版本。当我用这个版本的 Qt 运行 Qt 项目时，没有问题。但是当我运行 Qt Quick 应用程序时，程序崩溃并且以下消息登录调试:

我该如何解决这个问题？这个问题和我的显卡有关吗？

Answer 1

当您的显卡驱动程序不支持 Qt.Quick 应用程序所必需的 OpenGL 2.0 时，就会发生这种情况。

第一个解决方案是升级您的显卡驱动程序。您也可以使用 OpenGL extensions Viewer验证您支持哪些 OpenGL 版本。

另一方面，如果您希望能够将您的应用程序部署到其他 Windows 安装并且不想要求用户更新他们的驱动程序，那么您不应该使用基于 OpenGL 的 Qt5 构建，而是基于 ANGLE 的构建。遗憾的是，从 Qt 5.1 开始，Qt 团队停止发布带有 ANGLE 和 mingw 的 Qt 版本。所以你要么需要自己重新编译 Qt，要么使用基于另一个编译器的版本。

编辑 Qt5.3

上 Qt 5.3新信号已添加到 QQuickWindow叫 sceneGraphError这使您可以知道初始化失败，而不仅仅是获得一个空白屏幕。

此外，Qt 团队正在致力于首先在客户端计算机上尝试 OpenGL，如果失败则回退到 ANGLE。这在 Qt 5.3 中仍处于实验阶段并且应该是 Qt 5.4 的一部分释放。
