编译qt5.5.1步骤

1 去官网下载qt5.5.1，解压

vi qtbase/mkspecs/linux-arm-gnueabi-g++/qmake.conf 修改 MAKEFILE_GENERATOR = UNIX CONFIG += incremental QMAKE_INCREMENTAL_STYLE = sublib ########## add start ################## # note:下面的第二项根据CPU架构来设置，比如我这边是A9， # 如果是A8要设置成armv5te， # QT_QPA_DEFAULT_PLATFORM = linux QMAKE_CFLAGS_RELEASE += -O2 -march=armv7-a QMAKE_CXXFLAGS_RELEASE += -O2 -march=armv7-a ########## add end ################### include(../common/linux.conf) include(../common/gcc-base-unix.conf) include(../common/g++-unix.conf) ###########modify start ###################### # note：下面是对编译器的配置，我这里的编译工具全部修改成arm-linux-* ############################################## # modifications to g++.conf QMAKE_CC = arm-linux-gcc QMAKE_CXX = arm-linux-g++ QMAKE_LINK = arm-linux-g++ QMAKE_LINK_SHLIB = arm-linux-g++ # modifications to linux.conf QMAKE_AR = arm-linux-ar cqs QMAKE_OBJCOPY = arm-linux-objcopy QMAKE_NM = arm-linux-nm -P QMAKE_STRIP = arm-linux-strip load(qt_config) ##############modify end #####################

2 配置QT

a 先安装libpng库我的ubuntu版本是12.04， libpng库下载地址：http://pan.baidu.com/s/1mhXdY9E http://pan.baidu.com/s/1gfl1qEn 下载后dpkg -i *.deb安装即可 b 配置 ./configure -v -prefix /home/liuhaobi/qt5.5.1_20170103/__install -release -make libs -xplatform linux-arm-gnueabi-g++ -optimized-qmake -pch -qt-sql-sqlite -qt-libjpeg -qt-zlib -no-opengl -no-sse2 -no-openssl -no-nis -no-cups -no-glib -no-xcursor -no-xfixes -no-xrandr -no-xrender -no-separate-debug-info -nomake examples -nomake tools -no-iconv -dbus 出现一堆错误，暂时不管这些错误，可以先不管，有空再去一个个解决，PC上少库的缘故

3编译QT

make -j4

4 编译出现一系列错，下面对即将出现的错误逐一解决

（1）执行make -j4后出现第一个错误

Cannot find libdbus-1 in your system to resolve symbol 'dbus_get_local_machine_id'. 解决办法：安装libdbus库

（2） dbus-1.2.30安装

a 下载，解压dbus-1.2.30，下载地址：http://pan.baidu.com/s/1hs4wegs b 配置dbus-1.2.30 ./configure --host=arm-linux --prefix=/home/liuhaobi/qt5.5.1_20170103/expect_lib/dbus_install CC=arm-linux-gcc --without-x ###注意：--prefix选项是dbus-1.2.30的安装路径，根据自己的情况设置 ###本博主dbus-1.2.30安装路径：/home/liuhaobi/qt5.5.1_20170103/expect_lib/dbus_install c 编译dbus-1.2.30 make 提示错误 configure: error: Could not find expat.h, check config.log for failed attempts 原因：需要现安装 expat 。。。

（3）安装expat

a 下载，解压expat，下载地址：http://pan.baidu.com/s/1o8oASdG b 配置expat CC=arm-linux-gcc ./configure --host=arm-linux --prefix=/home/liuhaobi/qt5.5.1_20170103/expect_lib/expat_install ###注意：--prefix选项是expat的安装路径 ###本博主安装路径/home/liuhaobi/qt5.5.1_20170103/expect_lib/expat_install c 编译安装expat make 和 make install

（4）再次配置dbus，编译，安装

CC=arm-linux-gcc ./configure CFLAGS=-I/home/liuhaobi/qt5.5.1_20170103/expect_lib/expat_install/include LDFLAGS=-L/home/liuhaobi/qt5.5.1_20170103/expect_lib/expat_install/lib --prefix=/home/liuhaobi/qt5.5.1_20170103/expect_lib/dbus_install --host=arm-linux --enable-abstract-sockets

###注意：CFLAGS是expat的头文件路径，LDFLAGS是expat的库文件路径，--prefix是dbus-1.2.30的安装路径 make && make install

（5）移植完 dbus 库后,将 /opt/EmbedRigol/install-dev/dbus-1.2.30/lib 文件夹下 libdbus-1.so 相关的文件拷贝到开发板/lib 文件夹下，博主拷贝了全部文件及文件夹

在qt/qtbase/mkspecs/linux-arm-gnueabi-g++/qmake.conf加入以下内容 QMAKE_INCDIR += /home/liuhaobi/qt5.5.1_20170103/expect_lib/dbus_install/include/dbus-1.0 QMAKE_INCDIR += /home/liuhaobi/qt5.5.1_20170103/expect_lib/dbus_install/lib/dbus-1.0/include QMAKE_LIBDIR += /home/liuhaobi/qt5.5.1_20170103/expect_lib/dbus_install/lib 目前qmake.conf中内容为： MAKEFILE_GENERATOR = UNIX CONFIG += incremental

QMAKE_INCREMENTAL_STYLE = sublib

5 编译ts1.4

忽略，百度太多

6 开发板上给QT配置环境变量

#tslib环境变量配置 export TSLIBDIR=/home/tslib export TSLIB_CONSOLEDEVICE=none export TSLIB_FBDEVICE=/dev/fb0 export TSLIB_TSDEVICE=/dev/input/event2 export TSLIB_CALIBFILE=$TSLIBDIR/etc/pointercal export TSLIB_CONFFILE=$TSLIBDIR/etc/ts.conf export TSLIB_PLUGINDIR=$TSLIBDIR/lib/ts export PATH=/home/tslib/bin:$PATH export LD_LIBRARY_PATH=/home/tslib/lib:$LD_LIBRARY_PATH #QT环境变量配置 export QT_ROOT=/home/qt export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/lib:/usr/lib:$QT_ROOT/lib export QT_QPA_PLATFORM_PLUGIN_PATH=$QT_ROOT/plugins export QT_QPA_PLATFORM=linuxfb:tty=/dev/fb0 export QT_QPA_FONTDIR=$QT_ROOT/lib/fonts export QT_QPA_GENERIC_PLUGINS=tslib:/dev/input/event2 export QML2_IMPORT_PATH=$QT_ROOT/qml

7在开发板上运行程序

./testqt5 -platform linuxfb
