Qt:qt-everywhere-opensource-src-4.6.0.tar.gz
嵌入式平台:2440
arm-linux-gcc:4.1.2,下载(我用4.3.2和4.4.1版本时,移植时都有段错误。我把它放在:/usr/local/arm/4.1.2/ 。)
将 qt-everywhere-opensource-src-4.6.0.tar.gz 压缩包解压为3份,分别编译 PC ,嵌入式 x86 和 arm 三个版本。
1. 编译 PC 版:
$ ./configure
$ make
# make install
2. 编译嵌入式x86版:
$ ./configure -embedded x86 -qt-gfx-qvfb -qt-kbd-qvfb -qt-mouse-qvfb
$ make
# make install
编译安装PC版中的 qvfb:
$ cd ***/qt-everywhere-opensource-src-4.6.0/tools/qvfb
$ make
# cp ***/qt-everywhere-opensource-src-4.6.0/bin/qvfb /usr/local/Trolltech/QtEmbedded-4.6.0/bin
3. 编译嵌入式arm版(需要 arm-linux-gcc 的支持):
编译tslib对触摸屏支持:
下载,tslib1.4.tar.gz,解压后:
$ ./configure --prefix=/usr/local/tslib/ --host=arm-linux ac_cv_func_malloc_0_nonnull=yes
$ make
# make install
设置环境变量,以便编译时找到相关的库:
$ export
CPLUS_INCLUDE_PATH=/usr/local/arm/4.1.2/arm-angstrom-linux-gnueabi/include/c++:/usr/local/arm/4.1.2/arm-angstrom-linux-gnueabi/include/c++/arm-angstro
m-linux-gnueabi

如果出错:
/usr/local/arm/4.1.2/bin/../lib/gcc/arm-angstrom-l
inux-gnueabi/4.1.2/../../../../arm-angstrom-linux-g nueabi/bin/ld:

解决办法:
修改qt-everywhere-opensource-src-4.6.0/mkspecs/qws/lin ux-arm-g++/qmake.conf 文件(添加lts参数):
QMAKE_CC = arm-linux-gcc -lts
QMAKE_CXX = arm-linux-g++ -lts
QMAKE_LINK = arm-linux-g++ -lts
QMAKE_LINK_SHLIB = arm-linux-g++ -lts

sel-a
添加环境变量:# export PATH=/usr/local/arm/4.1.2/bin:$PATH
安装:# make install-strip
安装完成后,在 /usr/local/Trolltech 目录中有三个文件夹:Qt-4.6.0、QtEmbedded-4.6.0、QtEmbedded-4.6.0-arm。
测试嵌入式 x86 :
$ source ~/.setenv-qt-x86.sh
$ qvfb -width 800 -height 600 &
$ /usr/local/Trolltech/QtEmbedded-4.6.0/demos/books/ books -qws
4、编写环境变量设置文件(方便不同环境切换):
PC 机的~/.bashrc 中添加:
export PATH=$PATH:/usr/local/arm/4.1.2/bin
~/.setenv-qt-x11.sh(对应于PC版Qt):
PATH=/usr/local/Trolltech/Qt-4.6.0/bin:$PATH
LD_LIBRARY_PATH=/usr/local/Trolltech/Qt-4.6.0/lib: $LD_LIBRARY_PATH
CPLUS_INCLUDE_PATH=
~/.setenv-qt-x86.sh:
QTEDIR=/usr/local/Trolltech/QtEmbedded-4.6.0
PATH=/usr/local/Trolltech/QtEmbedded-4.6.0/bin:$PA TH
LD_LIBRARY_PATH=/usr/local/Trolltech/QtEmbedded-4. 6.0/lib:$LD_LIBRARY_PATH
~/.setenv-qt-arm.sh:
QTEDIR=/usr/local/Trolltech/QtEmbedded-4.6.0-arm
PATH=/usr/local/Trolltech/QtEmbedded-4.6.0-arm/bin :$PATH
LD_LIBRARY_PATH=/usr/local/Trolltech/QtEmbedded-4. 6.0-arm/lib:$LD_LIBRARY_PATH
CPLUS_INCLUDE_PATH=/usr/local/arm/4.1.2/arm-angstr
om-linux-gnueabi/include/c++:/usr/local/arm/4.1.2/a
rm-angstrom-linux-gnueabi/include/c++/arm-angstrom-
linux-gnueabi:$CPLUS_INCLUDE_PATH
5、移植
将 PC 机上 /usr/local/Trolltech/QtEmbedded-4.6.0-arm/lib 中的库复制到2440的 /usr/local/Trolltech/QtEmbedded-4.6.0-arm/lib(对应目录复制)。
将 PC 机上 /usr/local/tslib 中的库复制到2440的 /usr/local 。
如果运行时还缺少其他的库,复制方法相同。
为支持触摸屏,开机自动设置环境变量,在2440的 /etc/profile中追加:
export LD_LIBRARY_PATH=/usr/local/lib:$QTDIR/lib:$LD_LIBR ARY_PATH
export TSLIB_ROOT=/usr/local/lib
export TSLIB_TSDEVICE=/dev/input/event0
export TSLIB_FBDEVICE=/dev/fb0
export TSLIB_PLUGINDIR=/usr/local/lib/ts
export TSLIB_CONSOLEDEVICE=none
export TSLIB_CONFFILE=/usr/local/etc/ts.conf
export POINTERCAL_FILE=/etc/pointercal
export TSLIB_CALIBFILE=/etc/pointercal
export QWS_MOUSE_PROTO=Tslib:/dev/input/event0
注:可用$ cat /dev/input/event0 测试触摸屏
取消/usr/local/etc/ts.conf中的第一个注释:
# module_raw input (去掉#,并且该行顶格)
运行 /usr/local/bin/ts_calibrate 校正触摸屏。
6、程序编译:
PC版:
$ make distclean
$ source ~/.setenv-qt-x11.sh
$ qmake
$ make
arm 版:
$ make distclean
$ source ~/.setenv-qt-arm.sh
$ qmake
$ make
