[转]Qtopia2.2.0移植

 原文:http://blog.mcuol.com/User/longren/article/11362_1.htm

第一步：编译jpeg-6b得到jpeg库

先使用命令进行配置：./configure –enable-shared –enable-static –prefix=/install_software –build=i386 –host=arm

然后修改生成的Makefile ,如下：

CC=  gcc 修改为：CC= arm-linux-gcc

AR= ar rc 修改为：AR= arm-linux-ar rc

AR2= ranlib 修改为：AR2=arm-linux-ranlib

最后是编译和安装

make

安装之前要在安装的路径下面建几个目录： /man/man1 , /lib , /include , /bin,否则提示：

No such file or directory

make  install-lib

第二步：编译e2fsprogs-1.41.4 得到uuid库

在源文件目录下建立一个目录放mke2fs工具：mkdir build

# cd build

#../configure –with-cc=arm-linux-gcc  –with-linker=arm-linux-ld  --enable-elf-shlibs  --host=arm  -prefix=/install_software/e2fsprogs

编译

#make

错误：In file included from http://www.cnblogs.com/../lib/ext2fs/getsize.c:30:

/usr/local/arm/3.4.1/lib/gcc/arm-linux/3.4.1/http://www.cnblogs.com/http://www.cnblogs.com/arm-linux/sys-include/linux/fd.h:342: error: variable or field `__user'' declared void

make[2]: *** [getsize.o] Error 1

解决：在引用#include 的文档前面加上    #include

安装

make install-libs

第三步：编译触摸屏共享库tslib-1.0(tslib-1.4版本)

（1）# cd tslib-1.0/   进入tslib的目录

（2）# ./autogen.sh   生成config文件

（3）# echo "ac_cv_func_malloc_0_nonnull=yes" >arm-linux.cache  //为了防止出现undefined reference to `rpl_malloc'' 错误

（4）# ./configure –host=arm-linux –cache-file=arm-linux.cache  -enable-inputapi=no  --prefix=/opt/tslib1.4       //--prefix增加安装路径

（5）make

（6）make install

（7）库文件在 /tslib-1.0/src/.lib

（8）拷贝各种文件

 # cp ts_calibrate ts_harvest ts_print ts_print_raw ts_test   /long_nfs/myfs-1/qtopia/bin/tests/   //为根文件系统

# cp libts-0.0.so.0*  /long_nfs/myfs-1/qtopia/lib

# cp libts.so   /long_nfs/myfs-1/qtopia/lib

# cp tslib-1.0/plugins/.libs/*.so  /long_nfs/myfs-1/qtopia/lib/ts

第四步：实现qtopia-free-2.2.0的移植

（1）       拷贝库文件

拷贝uuid库

       cp –rfv  build/lib/uuid    qtopia/include

       cp –fvr  build/lib/libuuid.so*  /usr/local/arm/3.4.1/arm-linux/lib

       拷贝jpeg库

       cp -rfv libjpeg.so*  /Qtopia-repot/qtopia-free-2.2.0/qt2/lib

       cp -fvr jpeglib.h  /Qtopia-repot/qtopia-free-2.2.0/qt2/include  //解压出来没有include这个文件

       cp -rfv libjpeg.so*  /Qtopia-repot/qtopia-free-2.2.0/qtopia/lib

       cp -fvr jpeglib.h  /Qtopia-repot/qtopia-free-2.2.0/qtopia/include //include是自己建立的，以后连接的时候注意一下路径

（2） 配置命令如下：

       ./configure -qte ''embedded -no-xft -xplatform linux-arm-g++ -qc

onfig qpe -depths 16,32 -no-qvfb -system-jpeg -gif -tslib'' -qpe ''-xplatform linux-arm-g++ -edition

pda -displaysize 240x320'' -qt2 ''-no-xft'' -dqt ''-no-xft''

（3） 修改文件

  vi/home/arm/qtopia-free-2.2.0/qtopia/mkspecs/qws/linux-arm-g++/qmake.conf

将此行QMAKE_LIBS_QT = -lqte
    修改为
    QMAKE_LIBS_QT = -lqte -lpng -lts -lz -luuid –ljpeg  //(-lpng需要png库，-lts                 是连接ts库的)  

（4）       export QTDIR=/home/arm/qtopia-free-2.2.0/qt2

       export QPEDIR=/home/arm/qtopia-free-2.2.0/qtopia

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

       export TMAKEDIR=/home/arm/qtopia-free-2.2.0/tmake

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

cd $QPEDIR/src/libraries/qtopia
        cp custom-linux-ipaq-g++.cpp custom-linux-arm-g++.cpp
        cp custom-linux-ipaq-g++.h custom-linux-arm-g++.h 

（5）       另外一种configure方式，建议使用这种

#./configure -qte "-embedded -xplatform linux-arm-g++ -qconfig qpe-no-qvfb -depths 16,24 -system-jpeg -system-libpng -system-zlib -tslib -gif -thread -no-xft -release -I/home/arm/include -L//home/arm/lib -lpng -lts -lz-luuid -ljpeg" -qpe ''-xplatform linux-arm-g++ -edition pda -displaysize 320x240 -I/home/arm/include -L/home/arm/lib -prefix=/home/arm/qtopia''

解释：-I/是需要的头文件 –L/是需要连接的库文件，要增加触摸屏而且用到tslib的一定要加-lts ,-prefix=/是设置安装路径的

（6）       make  编译通过以后 make install 然后把相应的库文件拷贝到qtopia，然后将qtopia整个文件一起拷贝到根文件系统中，利用NFS挂载测试。 记着设置环境变量

export QTDIR=/qtopia

export QPEDIR=/qtopia

export QWS_MOUSE_PROTO=TPanel:/dev/ts0 (这个根据自己的情况设定)

export LD_LIBRARY_PATH=/qtopia/lib

export TSLIB_TSEVENTTYPE=H3600  对tslib中的设备结构体定义

export TSLIB_CONSOLEDEVICE=none tslib运行需要的控制台，这里就是LCD屏幕 ,设定控制台设备为none，否则默认为/dev/tty

export TSLIB_FBDEVICE=/dev/fb0  指定帧缓冲设备

export TSLIB_TSDEVICE=/dev/ts0 (这个根据自己的情况设定)

export TSLIB_CALIBFILE=/etc/pointercal指定触摸屏校准文件pintercal的存放位置

export TSLIB_CONFFILE=/etc/ts.conf 指定TSLIB设置文件的位置

export TSLIB_PLUGINDIR=$QTDIR/lib/ts 指定触摸屏插件所在路径

（7）       校准

#cd /qtopia/bin/tests

#./ts_calibrate

再运行测试

#./ts_test

运行PDA

#cd ..

#./qpe

出现“Tap anywhere to continue”,然后进行qpe5点校准，进入qpe

（8）       建立一个脚本用来运行qtopia，在开发板的根目录/bin下建立qpe.sh文件，它用来设置环境变量，启动qtopia，内容如下：

#!/bin/sh

export HOME=/root

export QTDIR=/qtopia

export QPEDIR=/qtopia

export QWS_DISPLAY=LinuxFb:/dev/fb0

export QWS_KEYBOARD="TTY:/dev/tty1"

#export QWS_MOUSE_PROTO="USB:/dev/mouse0"

export QWS_MOUSE_PROTO="TPanel:/dev/ts0"

export PATH=$QPEDIR/bin:$PATH

export LD_LIBRARY_PATH=$QPEDIR/lib:$LD_LIBRARY_PATH

export TSLIB_PLUGINDIR=$QTDIR/lib/ts

$QPEDIR/bin/qpe &

（9）       编译的时候出现的错误

make[1]: Leaving directory `/root/2410s/qtopia-free-2.2.0/qt2/src''

解决：将tslib/src目录下的tslib.h tslib-filter.h tslib-private.h拷贝到如下目录：

/root/2410s/qtopia-free-2.2.0/qtopia/include.

1:tsdev (compaq touchscreen emulation) is scheduled for removal.

See Documentation/feature-removal-schedule.txt for details.

这句是内核发出的，在drivers\input\Tsdev.c   tsdev_open()

2: option `module_raw'' not recognized

3: Cannot configure touchscreen /dev/ts0 (No such file or directory)

  qt2\src\kernel\qwsmouse_qws.pp openTs() 发出的

  解决：将plugins拷贝到根文件系统，正确指定export TSLIB_PLUGINDIR。

4: Couldnt load module input

No raw modules loaded.

ts_config: Success

解决：正确设置TSLIB_PLUGINDIR，而且要在/etc/profile中设置
