Qt5.2.1交叉编译,带tslib插件

转自Qt5.2.1交叉编译,带tslib插件

一: 源码下载地址:

1.1: 平台:

主机:ubuntu 14.04

开发板: cpu arm-cortex-a8,故而我在配置我的qmake.conf的时候填写的为armV7-a

QT版本: qt everywhere opensource 5.2.1

Busybox版本:busybox-1.22.0

arm交叉编译工具:arm-none-linux-gnueabi 4.8.1

1.2: 交叉编译工具:

版本: arm-none-linux-gnueabi 4.8.1

附上我用的交叉编译工具,我把他上传到csdn是为了备份.由于我的账号在csdn的限制为60M,故而我将文件分为了8份.由于写这篇文章的时候上传的资料智能看见第八份,故而这里只有这么一个链接.

1.3: Qt5.2.1下载地址:

http://download.qt-project.org/archive/qt/5.2/5.2.1/single/qt-everywhere-opensource-src-5.2.1.tar.gz

1.4: tslib1.4下载地址:

二: 交叉编译

步骤如下:

1:安装交叉编译工具

1.1: 将下载的交叉编译工具解压(用sudo解压),得到一个arm-4.8.1的文件夹,将其移动到/usr/local下面去

1.2: 添加全局环境变量: 

vim /etc/bash.bashrc,在此文件的最后写上这一句:

 export PATH=/usr/local/arm-4.8.1/bin:$PATH

2:交叉编译tslib1.4

2.1:解压tslib1.4并进入其中,编写配置文件

 vim configTslib14.sh

在此文件中写入以下内容并保存退出:

 #!/bin/sh
 make clean && make distclean
 echo "ac_cv_func_malloc_0_nonnull=yes" >arm-linux.cache
 CC=/usr/local/arm-4.8.1/bin/arm-linux-gcc ./configure --host=arm-linux --prefix=/usr/local/tslib1.4 --cache-file=arm-linux.cache
 make && make install

然后:

 chmod a+x  configTslib14.sh && sudo ./configTslib14.sh

3:解压qteverywhere包:

 tar -xvf  qt-everywhere-opensource-src-5.2.1.tar.gz && cd qt-everywhere-opensource-src-5.2.1

3.1:编写configure文件:

vim 或者 

 gedit configInstallQt5.2.1.sh

根据需要在里面写入需要的configure内容,我的配置如下:

 ./configure -prefix /usr/local/qt-5.2.1-embedded-arm-linux -release -opensource -qt-libpng -qt-libjpeg -plugin-sql-sqlite -widgets -qt-sql-sqlite -make libs -no-cups -no-nis -no-iconv -no-dbus -no-openssl -no-iconv -no-accessibility -no-javascript-jit  -no-sse2 -silent -xplatform  linux-arm-gnueabi-g++  -nomake tools -nomake examples -nomake tests -qt-freetype  -no-glib -strip -linuxfb -plugindir /usr/local/qt-5.2.1-embedded-arm-linux/plugins -I/usr/local/tslib1.4/include -L/usr/local/tslib1.4/lib -confirm-license "$@" -verbose

3.3:配置qmake.conf

 vim qtbase/mkspecs/linux-arm-gnueabi-g++/qmake.conf

我的此文件配置如下:

 MAKEFILE_GENERATOR      = UNIX
 CONFIG                 += incremental gdb_dwarf_index
 QMAKE_INCREMENTAL_STYLE = sublib
 QT_QPA_DEFAULT_PLATFORM = linuxfb
 QMAKE_CFLAGS_RELEASE   += -O2 -march=armv7-a
 QMAKE_CXXFLAGS_RELEASE += -O2 -march=armv7-a

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

 QMAKE_INCDIR += /usr/local/tslib1.4/include
 QMAKE_LIBDIR += /usr/local/tslib1.4/lib

 QMAKE_CC                = /usr/local/arm-4.8.1/bin/arm-none-linux-gnueabi-gcc -lts
 QMAKE_CXX               = /usr/local/arm-4.8.1/bin/arm-none-linux-gnueabi-g++ -lts
 QMAKE_LINK              = /usr/local/arm-4.8.1/bin/arm-none-linux-gnueabi-g++ -lts
 QMAKE_LINK_SHLIB        = /usr/local/arm-4.8.1/bin/arm-none-linux-gnueabi-g++ -lts

 QMAKE_AR                = /usr/local/arm-4.8.1/bin/arm-none-linux-gnueabi-ar cqs
 QMAKE_OBJCOPY           = /usr/local/arm-4.8.1/bin/arm-none-linux-gnueabi-objcopy
 QMAKE_NM                = /usr/local/arm-4.8.1/bin/arm-linux-gnueabi-nm -P
 QMAKE_STRIP             = /usr/local/arm-4.8.1/bin/arm-none-linux-gnueabi-strip

 load(qt_config)

执行:

 chmod a+x configInstallQt5.2.1.sh &&  sudo ./configInstallQt5.2.1.sh && sudo make -j 8 && sudo make install -j 8

3.4:为qt添加tslib插件

 vim tslibPluginInstall.sh

 sudo cp qt-everywhere-opensource-src-5.2.1/qtbase/bin/qmake /usr/bin/qmake_emb_5.2.1
 cd qt-everywhere-opensource-src-5.2.1/qtbase/src/plugins/generic/tslib/
 sudo cp /usr/local/tslib1.4/include/tslib.h ./
 qmake_emb_5.2.1
 sudo make && sudo make install

 chmod a+x tslibPluginInstall.sh && sudo ./tslibPluginInstall.sh

三:将编译好的qt库以及tslib库移植到文件系统中并写好配置文件

根据需要将qt下面的库拷贝到文件系统,包括qt安装目录下面的plugins文件夹

 vim qtAndTsInstall.sh

 #!/bin/sh
 QTPATH=/usr/local/qt-5.2.1-embedded-arm-linux
 TSLIBPATH=/usr/local/tslib1.4
 NFSROOTPATH=~/nfsroot
 rm -rf $NFSROOTPATH$QTPATH/fonts
 cp ./fonts $NFSROOTPATH$QTPATH/ -arf
 sudo cp $QTPATH/lib/* $NFSROOTPATH$QTPATH/ -arf
 sudo cp $TSLIBPATH $NFSROOTPATH/ -arf
 rm -rf $NFSROOTPATH$QTPATH/*.la $NFSROOTPATH$QTPATH/*.prl
 sudo cp $QTPATH/plugins $NFSROOTPATH$QTPATH/ -arf

 chmod a+x qtAndTsInstall.sh && sudo ./qtAndTsInstall.sh

文件系统的profile文件如下:

 vim ~/nfsroot/etc/profile

 export QTDIR=/usr/local/qt-5.2.1-embedded-arm-linux
 export PATH=$QTDIR:$PATH
 export QT_QPA_PLATFORM_PLUGIN_PATH=$QTDIR/plugins
 export QT_QPA_PLATFORM=linuxfb:tty=/dev/fb0
 export QT_QPA_FONTDIR=$QTDIR/fonts
 export TSLIB_ROOT=/usr/local/tslib1.4
 export TSLIB_CALIBFILE=/etc/pointercal
 export TSLIB_CONFFILE=$TSLIB_ROOT/etc/ts.conf
 export TSLIB_FBDEVICE=/dev/fb0
 export TSLIB_PLUGINDIR=$TSLIB_ROOT/lib/ts
 export TSLIB_CONSOLEDEVICE=none
 export TSLIB_TSDEVICE=/dev/touchscreen
 export QT_QPA_GENERIC_PLUGINS=tslib:$TSLIB_TSDEVICE
 export QWS_MOUSE_PROTO=tslib:$TSLIB_TSDEVICE
 export set QWS_DISPLAY=LinuxFb:/dev/fb0
 export set QWS_SIZE=640x480
 export set QT_QWS_FONTDIR=$QTDIR/fonts/
 export set LD_LIBRARY_PATH=$QTDIR:$QT_QPA_PLATFORM_PLUGIN_PATH:$QT_QPA_FONTDIR:$TSLIB_ROOT/lib:$TSLIB_PLUGINDIR:$LD_LIBRARY_PATH

这样整个文件系统的环境就搭好了.交叉编译的时候用qmake_emb_5.2.1就可以了.

运行的时候直接运行,例如: ./test
