我试图通过指定hellogl_es2
平台来运行没有X服务器的eglfs
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。
分发是Ubuntu 14.04.4 LTS(可靠)。
Qt版本为5.2.1,已从http://packages.ubuntu.com,armhf
架构,软件包qtbase5-dev
,qtbase5-examples
,qtbase5-examples-dbg
安装。
核心转储是(gcoOS_InitLocalDisplayInfo
中的libGAL.so
处的问题):

该行为与其他Qt示例项目相同。
当X服务器正在运行时,指定xcb
平台(-platform xcb
,即默认值)工作正常。
答案 0 :(得分:0)
我设法解决了“分段错误”问题:
apt-get install gpu-viv-bin-mx6q-fb
(自动卸载gpu-viv-bin-mx6q-x11
)。
