哪位大神手动编译过qt5.6,支持opengl，帮忙看一下，感激不尽！
#4 [自强不吸 10-19 16:27]
我的编译完运行程序的时候 ：
./demo -platform eglfs
会报错：./demo: symbol lookup error: /opt/openGlES/lib/libEGL.so.1: undefined sym
bol: gcoOS_GetTLS
如果直接运行：./demo
会有这个错误：
This plugin does not support createPlatformOpenGLContext!
QtQuick: failed to create OpenGL context
实在是有点头疼，搞了几天了
