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
