QT 5.7.0 交叉编译记录

• 这一篇记录 Qt 5.x cross-compiler with eglfs , 平台是 TI-AM3354, 上一篇SGX的移植就是为了这一次的交叉编译。

• 一、 下载QT的源码：

    地址： http://download.qt.io/official_releases/qt/5.7/5.7.0/single/

• 二、 解压并配置

    //  定义一个配置脚本
    //  vim  ti_qtcon.sh
    #!/bin/sh                                                                       

    ./configure -v -opensource -confirm-license -no-pch \
        -prefix /home/sbc_7109_454_pdk3/qt_5.7/qtlib \
        -release  \
        -opengl es2 -make libs -device linux-beagleboard-g++ \
        -device-option  CROSS_COMPILE=/home/sbc_7109_454_pdk3/ti_sdk/linux-devkit/sysroots/x86_64-arago-linux/usr/bin/arm-linux-gnueabihf- \
        -sysroot /home/sbc_7109_454_pdk3/ti_sdk/linux-devkit/sysroots/armv7ahf-neon-linux-gnueabi \
        -linuxfb    \
        -eglfs \
        -no-gcc-sysroot \
        -make examples -make tools -nomake tests

    // 再看一下
    //  vim qtbase/mkspecs/devices/linux-beagleboard-g++/qmake.conf

• 编译

    make
    make install

    生成的文件会放在  sysroot 下面的 /home/sbc_7109_454_pdk3/qt_5.7/qtlib  里面
