RaspberryPi2EGLFS - Qt Wiki
A modern guide for cross-compiling Qt for HW accelerated OpenGL with eglfs on Raspbian and setting up Qt Creator Initial notes This is not intended for running desktop-style, windowed Qt apps under X11, but rather for the real embedded/device creation use

-모듈의 추가빌드:
| 위와 와 같이 하나 하나 하면 된다. 문제가 안되게 빌드하려면 아래의 순서대로 빌드를 해야한다. (패키지별로 종속적인 관계가 있다.) qtimageformats, qtsvg, qtscript, qtxmlpatterns, qtdeclarative, qtsensors, qt3d, qtgraphicaleffects, qtjsondb, qtlocation, qtdocgallery 테스트를 해보니까 최소한 qtdeclarative 까지는 설치하는 것이 좋을 것 같다.
