1、安装Qt-Embedded-linux

安装Qt-Embedded-linux有两种方法,一种是从源码安装,一种是直接安装。如果不需要在PC机上进行Qt-Embedded程序调试,可以不需要安装Qt-x11和Qt-Embedded for x86

(1) 源码安装
首先从 ftp://ftp.trolltech.com/qt/source/ 下载以下源码包:
qt-x11-opensource-src-4.4.1.tar.bz2
qt-embedded-linux-opensource-src-4.4.0.tar.bz2

安装Qt-x11
# tar jxvf qt-x11-opensource-src-4.4.1.tar.bz2
# cd qt-x11-opensource-src-4.4.0
# echo "yes" | ./configure
# make && make install

安装Qt-Embedded for x86
# tar jxvf qt-embedded-linux-opensource-src-4.4.0.tar.bz2
# mv qt-embedded-linux-opensource-src-4.4.0 qt-embedded-linux-opensource-src-4.4.0-x86
# cd qt-embedded-linux-opensource-src-4.4.0-x86
# echo "yes" | ./configure \
-prefix /usr/local/Trolltech/QtEmbedded-4.4.0 \
-release \
-shared \
-no-qt3support \
-no-xmlpatterns \
-no-svg \
-no-webkit \
-system-zlib \
-qt-gif \
-system-libtiff \
-system-libpng \
-qt-libmng \
-system-libjpeg \
-make libs \
-make tools \
-nomake examples \
-nomake docs \
-nomake demo \
-no-nis \
-no-cups \
-no-iconv \
-no-dbus \
-no-openssl \
-xplatform qws/linux-x86-g++ \
-embedded x86 \
-qt-freetype \
-depths 16,18 \
-qt-gfx-qvfb \
-no-gfx-transformed \
-no-gfx-multiscreen \
-no-gfx-vnc \
-no-gfx-linuxfb \
-qt-kbd-tty \
-qt-kbd-usb \
-qt-kbd-qvfb \
-qt-mouse-pc \
-qt-mouse-qvfb \
-no-glib
# make && make install

安装Qt-Embedded for ARM
# tar jxvf qt-embedded-linux-opensource-src-4.4.0.tar.bz2
# mv qt-embedded-linux-opensource-src-4.4.0 qt-embedded-linux-opensource-src-4.4.0-arm
# cd qt-embedded-linux-opensource-src-4.4.0-arm
# echo "yes" | ./configure \
-prefix /opt/Trolltech/QtEmbedded-4.4.0 \
-release \
-shared \
-no-qt3support \
-no-xmlpatterns \
-no-svg \
-no-webkit \
-system-zlib \
-qt-gif \
-system-libtiff \
-system-libpng \
-qt-libmng \
-system-libjpeg \
-make libs \
-make tools \
-nomake examples \
-nomake docs \
-nomake demo \
-no-nis \
-no-cups \
-no-iconv \
-no-dbus \
-no-openssl \
-xplatform qws/linux-arm-g++ \
-embedded arm \
-little-endian \
-qt-freetype \
-depths 16,18 \
-qt-gfx-linuxfb \
-no-gfx-transformed \
-no-gfx-multiscreen \
-no-gfx-vnc \
-no-gfx-qvfb \
-qt-kbd-tty \
-qt-kbd-usb \
-qt-mouse-tslib \
-qt-mouse-pc \
-no-glib
# make && make install

2、程序调试和帮助

在PC机上调试Qt-Embedded程序的方法为,使用Qt-Embedded for x86的Qt库来编译Qt-Embedded程序,然后使用Qt-x11的qvfb工具仿真调试。下面以demo程序为例:
# tar jxvf demo.tar.bz2
# cd demo
# /usr/local/Trolltech/QtEmbedded-4.4.0/bin/qmake -project
# /usr/local/Trolltech/QtEmbedded-4.4.0/bin/qmake
# make
# /usr/local/Trolltech/Qt-4.4.0/bin/qvfb &
# ./demo -qws

远行以下程序可以查看Qt编程,调试,应用,布署等各方面的帮助。
# /usr/local/Trolltech/Qt-4.4.0/bin/assistant


3、将Qt-Embedded程序运行在目标板上

用Qt-Embedded for ARM编译Qt-Embedded应用程序,以demo为例:
# tar jxvf demo.tar.bz2
# cd demo
# /opt/Trolltech/QtEmbedded-4.4.0/bin/qmake -project
# /opt/Trolltech/QtEmbedded-4.4.0/bin/qmake
# make

将demo程序下载到目标板上,然后就可以运行demo程序。在运行程序前以下环境变量必须已经设置。

export QTDIR=/opt/Trolltech/QtEmbedded-4.4.0
export PATH=$QTDIR/bin:$PATH
export QWS_DISPLAY=LinuxFb:/dev/fb0
export QWS_SIZE=640x480
export QWS_SW_CURSOR=1
export QWS_MOUSE_PROTO=Tslib:/dev/ep93xx_ts
export QWS_KEYBOARD=TTY:/dev/tty0
export QT_ONSCREEN_PAINT=0
export PONTERCAL_FILE=/etc/pointercal

export LD_LIBRARY_PATH=$QTDIR/lib:/lib:/usr/lib:$LD_LIBRARY_PATH

export TSLIB_TSDEVICE=/dev/ep93xx_ts
export TSLIB_CALIBFILE=/etc/pointercal
export TSLIB_CONFFILE=/etc/ts.conf
export TSLIB_PLUGINDIR=/lib/ts
export TSLIB_CONSOLEDEVICE=/dev/tty
export TSLIB_FBDEVICE=/dev/fb0
