linux - 使用 -platform eglfs 运行 Qt5 应用程序时 i.MX6 上的段错误

Question

我正在尝试通过指定 eglfs 平台运行没有 X Server 的 hellogl_es2 Qt 示例:

> ./hellogl_es2 -platform eglfs
No protocol specified
Segmentation fault (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(libGAL.so 中的gcoOS_InitLocalDisplayInfo 的问题):

行为与其他 Qt 示例项目相同。

当 X Server 运行时，指定 xcb 平台(-platform xcb，即默认值)工作正常。

我设法解决了“段错误”问题:

apt-get install gpu-viv-bin-mx6q-fb

(自动卸载​​ gpu-viv-bin-mx6q-x11)。

但是，现在我有另一个问题:"EGL Error : could not create the EGL surface: error 0x300b" on i.MX6 when running Qt5 application with -platform eglfs
