使用-platform eglfs運行Qt5應用程序時，i.MX6上的“EGL錯誤：無法創建EGL表面：錯誤0x300b”

Question

我試圖通過指定eglfs平台來運行沒有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是飛思卡爾i.MX6。

Linux內核是3.10.17。

分發是Ubuntu 14.04.4 LTS（可靠）。

Qt版本是5.2.1，安裝自http ://packages.ubuntu.com，armhf架構，軟件包qtbase5-dev，qtbase5-examples，qtbase5-examples-dbg。

核心轉儲是：

該行為與其他Qt示例項目相同。

我試圖從有或沒有應用此補丁的來源重新制作Qt： https ： //patchwork.openembedded.org/patch/66349/但沒有結果（相同的錯誤）。

我有這個問題在Cubieboard A10上使用qt 5.2並通過從源代碼編譯修改它並根據本教程改變qeglfshooks_stub.cpp Qt在Cubieboard上

希望這可以幫助
