linux下qt环境搭建

        此文借鉴了很多别人的东西，纯粹记录自己的实现过程。

 

交叉编译环境

       开发板为YLE2440，使用cross-3.4.1.tar.bz2交叉编译链，在linux系统的/usr/local/建立arm文件夹，将工具包解压：

       tar jxvf cross-3.4.1.tar.bz2

      编辑/etc/profile文件，在最后一行加入export PATH=/usr/local/arm/usr/local/arm/3.4.1/bin:$PATH

qt环境搭建

      需要的文件tmake-1.11，qt-X11-2.3.2，qt-embedded-2.3.7(for host)，qt-embedded-2.3.7(for target)，qtopia-free-1.7.0.其中，qt-embedded-2.3.7(for host)是在虚拟环境中交叉编译，qt-embedded-2.3.7(for target)则是提供实际的编译库。

现在，先是把原来的压缩文件解压俩次分别命名，后面会进行编译。

首先解压缩各种文件

tar xfz tmake-1.11.tar.gz

tar xfz qt-x11-2.3.2.tar.gz

tar xfz qt-embedded-2.3.7-free.tar.gz

1.安装tmake，就是设定编译器的路径

export TMAKEDIR=$PWD/tmake-1.11

export QT2DIR=$PWD/qt-2.3.2

export QTEDIR=$PWD/qt-2.3.7-host

export TMAKEPATH=$TMAKEDIR/lib/qws/linux-x86-g++ 

export PATH=$TMAKEDIR/bin:$PATH

2.安装Qt/X11 2.3.2

cd qt-2.3.2

export TMAKEPATH=$TMAKEDIR/lib/linux-g++

export QTDIR=$QT2DIR

export PATH=$QTDIR/bin:$PATH

export LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH

make clean

./configure -no-xft

make

安装成功！终端显示：The Qt library is now built in ./lib
The Qt examples are built in the directories in ./examples
The Qt tutorials are built in the directories in ./tutorial
Note: be sure to set $QTDIR to point to here or to wherever
      you move these directories.

make[1]: Leaving directory `/usr/xdq/qt-2.3.2'

为了使用uic以及qvfb:

cp bin/uic $QTEDIR/bin/

cd ..

编译qvfb工具：

cd $QTEDIR/tools/qvfb

make  clean

tmake -o Makefile qvfb.pro

make

mv qvfb $QTEDIR/bin/   

3.安装Qt/Embedded 2.3.7

cd qt-2.3.7-host

export QTDIR=$ QTEDIR

export PATH=$QTDIR/bin:$PATH

export LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH

./configure -no-xft -qvfb -depths 4,8,16,32

make sub-src

cd ..

–qconfig local这个参数是说明编译时用自带的一个配置文件qconfig-local，需要先将其copy到qt-2.3.7/src/tools/下.

编译完成，测试一下结果，是在上位机上运行的。

export QTDIR=$QTEDIR

export PATH=$QTEDIR/bin:$PATH

export LD_LIBRARY_PATH=$QTEDIR/lib:$QT2DIR/lib:$LD_LIBRARY_PATH

cd $QTEDIR/examples/hello

qvfb -width 640 -height 480 &

sleep 10

./hello –qws

交叉编译平台：安装qt-2.3.7-target

export TMAKEDIR=$PWD/tmake-1.11

export QT2DIR=$PWD/qt-2.3.2

export QTEDIR=$PWD/qt-2.3.7-target

cd $QTEDIR

export TMAKEPATH=$TMAKEDIR/lib/qws/linux-arm-g++/          主要是tmake中编译器的区别

export QTDIR=$QTEDIR

export PATH=$QTDIR/bin:$PATH

export LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH

make  clean

./configure -xplatform linux-arm-g++ -qconfig local -shared -debug -no-xft -qvfb -depths 4,8,16,32

make

编译成功，主要是提供各种库啊。。。The Qt library is now built in ./lib
The Qt examples are built in the directories in ./examples
The Qt tutorials are built in the directories in ./tutorial
 
Note: be sure to set $QTDIR to point to here or to wherever
      you move these directories.

make[1]: Leaving directory `/usr/xdq/qt-2.3.7-target'

4.编译qtopia

cd $QPEDIR/src
 export LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH
 make

 

5、执行qpe

root@localhost src]# cd ..
[root@localhost qtopia]# cd bin/
[root@localhost bin]# ./qpe

能出界面啦。。。
