記錄 qt5 x11  opengl  過程

我使用的是 debian 7 系統  下載 debian 基礎包

配置qt5

SUNXI_SYSROOT  是 我們debian 的目錄

./configure -v -debug -opensource -confirm-license -no-use-gold-linker \
  -nomake examples -nomake tests -nomake tools -no-cups -no-pch -no-linuxfb \
  -skip qtquick1 -skip declarative -skip multimedia -opengl es2 -no-eglfs \
  -system-xcb -system-zlib -sysroot $SUNXI_SYSROOT -device linux-sunxi-g++ \
  -device-option CROSS_COMPILE=arm-linux-gnueabihf- -prefix /opt/qt/sunxi
 

make install 

編譯過程可能遇到找不到 dbus  加上 no-dbus 即可

完成  刷機到a20  應該可以了

編譯qt 之前需要 安裝mali 環境  後面來補充
