首先按照ti的教程编译Graphics_SDK_5_01_01_02，编译后安装到rootfs
下载qt4.8.6, 编译安装qt和tslib。
按照 打上2个补丁，不然编译出错。
先测试SDK的例程，一般能正常运行。
测试qt的opengl例程，会报错，/opt/qt-4.8.6-arm/examples/opengl/textures# ./textures -qws -display powervr
按照 ，解决错误。

补充：
error: no matching function for call to 'qBound
可以采用qt5.5.1
搜索Unable to create EGL surface, error = 0x300b
