linux - 当使用 -platform eglfs 运行 Qt5 应用程序时，i.MX6 上的 "EGL Error : could not create the EGL surface: error 0x300b"

Question

我正在尝试通过指定 eglfs 平台在没有 X Server 的情况下运行 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。

发行版是 Ubuntu 14.04.4 LTS(可信)。

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

核心转储是:

行为与其他 Qt 示例项目相同。

我尝试使用或不使用此补丁从源代码重新制作 Qt: https://patchwork.openembedded.org/patch/66349/但没有结果(同样的错误)。
