为树莓派3B 编译QT 5.7.1

 

 

 

Download QT everywhere package :

http://download.qt.io/archive/qt/5.7/5.7.1/single/qt-everywhere-opensource-src-5.7.1.zip

Download Raspberry cross compiler :

https://github.com/raspberrypi/tools

dump rootfs from Rasberry SD card
 

scp pi@XXXXX:/lib  /(host_workspace)/lib

scp pi@XXXXX:/usr  /(host_workspace)/usr

scp pi@XXXXX:/opt /(host_workspace)/opt

Dowload tslib and compile

 

CROSS COMPILE QT:

1) uncompress QT package to some where.

/opt/workspace/qt-everywhere-opensource-src-5.7.1

2) make build dir under the QT root dir
 

set arm-linux-gnueabihf-gcc into $PATH

cp linux-arm-gnueabi-g++ in the qtbase/mkspec as linux-arm-gnueabihf-g++

cp linux-rpi2-g++ in the qtbase/mkspec/device as linux-rpi3-g++

mkdir build

cd build
