使用-platform eglfs运行Qt5应用程序时，i.MX6上的“EGL错误：无法创建EGL表面：错误0x300b”

Question

我试图通过指定eglfs平台来运行没有X Server的hellogl_es2 Qt示例：

./hellogl_es2 -platform eglfs
EGL Error : Could not create the egl surface: error = 0x300b

Aborted (core dumped)

CPU是飞思卡尔i.MX6。

Linux内核是3.10.17。

分发是Ubuntu 14.04.4 LTS（可靠）。

Qt版本是5.2.1，安装自http ://packages.ubuntu.com，armhf架构，软件包qtbase5-dev，qtbase5-examples，qtbase5-examples-dbg。

核心转储是：

该行为与其他Qt示例项目相同。

我试图从有或没有应用此补丁的来源重新制作Qt： https ： //patchwork.openembedded.org/patch/66349/但没有结果（相同的错误）。

我有这个问题在Cubieboard A10上使用qt 5.2并通过从源代码编译修改它并根据本教程改变qeglfshooks_stub.cpp Qt在Cubieboard上

希望这可以帮助
