全志T3(armhf) - QT5(qt5.15.10)编译与使用

1. 导入交叉编译器路径加入PATH

export PATH=$PATH:/opt/ext-toolchain/bin/

我的交叉编译工具链放在 /opt/ext-toolchain下

ls /opt/ext-toolchain
arm-linux-gnueabihf  bin  gcc-linaro-5.3.1-2016.05-linux-manifest.txt  include  lib  libexec  share
ls /opt/ext-toolchain/bin
arm-linux-gnueabihf-addr2line  arm-linux-gnueabihf-cpp        arm-linux-gnueabihf-gcc-ar      arm-linux-gnueabihf-gdb       arm-linux-gnueabihf-nm       arm-linux-gnueabihf-size
arm-linux-gnueabihf-ar         arm-linux-gnueabihf-elfedit    arm-linux-gnueabihf-gcc-nm      arm-linux-gnueabihf-gfortran  arm-linux-gnueabihf-objcopy  arm-linux-gnueabihf-strings
arm-linux-gnueabihf-as         arm-linux-gnueabihf-g++        arm-linux-gnueabihf-gcc-ranlib  arm-linux-gnueabihf-gprof     arm-linux-gnueabihf-objdump  arm-linux-gnueabihf-strip
arm-linux-gnueabihf-c++        arm-linux-gnueabihf-gcc        arm-linux-gnueabihf-gcov        arm-linux-gnueabihf-ld        arm-linux-gnueabihf-ranlib   gdbserver
arm-linux-gnueabihf-c++filt    arm-linux-gnueabihf-gcc-5.3.1  arm-linux-gnueabihf-gcov-tool   arm-linux-gnueabihf-ld.bfd    arm-linux-gnueabihf-readelf  runtest

可以看到交叉编译使用的 arm-linux-gnueabihf-g++ 在这个目录下

2. 下载解压qt源码

官网下载地址:

中科大镜像下载地址:

https://mirrors.ustc.edu.cn/qtproject/archive/qt/5.15/5.15.10/single/

3. 配置QT编译选项

build.sh

./qt-everywhere-src-5.15.10/configure \
 -xplatform linux-arm-gnueabi-g++ \
 -prefix ./qt-5.15.10  \
 -opensource \
  -confirm-license \
  -release \
  -strip \
  -shared \
  -optimized-qmake \
  -c++std c++11 \
  -no-pch \
  -skip qt3d \
  -skip qtandroidextras \
  -skip qtconnectivity \
  -skip qtdoc \
  -skip qtgamepad \
  -skip qtlocation \
  -skip qtmacextras \
  -skip qtnetworkauth \
  -skip qtpurchasing \
  -skip qtremoteobjects \
  -skip qtscript \
  -skip qtscxml \
  -skip qtsensors \
  -skip qtspeech \
  -skip qtsvg \
  -skip qttools \
  -skip qttranslations \
  -skip qtwayland \
  -skip qtwebengine \
  -skip qtwebview \
  -skip qtwinextras \
  -skip qtx11extras \
  -skip qtxmlpatterns \
  -make libs \
  -make examples \
  -nomake tools -nomake tests \
  -gui \
  -widgets \
  -dbus-runtime \
  --glib=no \
  --iconv=no \
  --pcre=qt \
  --zlib=qt \
  -no-openssl \
  --freetype=qt \
  --harfbuzz=qt \
  -no-opengl \
  -linuxfb \
  --xcb=no \
  --libpng=qt \
  --libjpeg=qt \
  --sqlite=qt \
  -plugin-sql-sqlite \
  -recheck-all

执行完成后会生成很多makefile

可以看到 我们的编译去使用的是armhf的,但是配置脚本指定的是linux-arm-gnueabi-g++,因此需要适配

qt-everywhere-src-5.15.10/qtbase/mkspecs/linux-arm-gnueabi-g++$ cat qmake.conf
#
# qmake configuration for building with arm-linux-gnueabi-g++
#

MAKEFILE_GENERATOR      = UNIX
CONFIG                 += incremental
QMAKE_INCREMENTAL_STYLE = sublib

include(../common/linux.conf)
include(../common/gcc-base-unix.conf)
include(../common/g++-unix.conf)

# modifications to g++.conf
QMAKE_CC                = arm-linux-gnueabihf-gcc
QMAKE_CXX               = arm-linux-gnueabihf-g++
QMAKE_LINK              = arm-linux-gnueabihf-g++
QMAKE_LINK_SHLIB        = arm-linux-gnueabihf-g++

# modifications to linux.conf
QMAKE_AR                = arm-linux-gnueabihf-ar cqs
QMAKE_OBJCOPY           = arm-linux-gnueabihf-objcopy
QMAKE_NM                = arm-linux-gnueabihf-nm -P
QMAKE_STRIP             = arm-linux-gnueabihf-strip
load(qt_config)

就是将其中的arm-linux-gnueabi-g++ 改为 arm-linux-gnueabihf-g++

4. 执行编译

make

编译完成后,生成的代码会放到 qtbase目录下

5. 将编译好的QT部署到执行环境中

我将qtbase放到了执行环境的 /usr/loca/qt5.15.10下

 

QT触摸插件tslib自行编译

6. 在执行环境中配置QT环境变量-使用linuxfb进行渲染/使用触摸屏tslib

#!/bin/sh
#export QT_DEBUG_PLUGINS=1                                  # 调试加载LOG
