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
