树莓派2+ qt5 交叉编译过程

1、下载qt5源码

    git clone git://code.qt.io/qt/qt5.git cd qt5
    ./init-repository

2、配置

    ./configure -opengl es2 -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=/home/erain/work/raspberrypi/src/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf- -sysroot /mnt/raspberry-sysroot/ -opensource -confirm-license -optimized-qmake -reduce-exports -release -make libs -prefix /home/erain/work/raspberrypi/src/qt/qt-install -hostprefix /home/erain/work/raspberrypi/src/qt/qt-install
    注：

    1、交叉编译连使用github上的raspberrypi/tools下面的

    2、-sysroot 使用镜像，挂载方法

3、编译安装

    make -j4

    make install

4、设置qtcreater

    5、设置。pro

    树莓派环境设置

    

    export QT_ROOT=/home/pi/qt5pi/


    export LD_LIBRARY_PATH=$QT_ROOT/lib:$LD_LIBARAY_PATH
    export QT_QPA_PLATFORM_PLUGIN_PATH=$QT_ROOT/plugins
    export QT_QPA_PLATFORM=linuxfb:tty=/dev/fb0
    export QT_QPA_FONTDIR=$QT_ROOT/lib/fonts
    export LD_PRELOAD=/usr/lib/preloadable_libiconv.so:$TSLIB_ROOT/lib/libts.so
    export QT_QPA_GENERIC_PLUGINS=tslib
