一、文档简介：

本文档用于介绍Loongson1B开发板上移植QT-3以及相关运行环境的搭建。

开发环境参数：

操作系统：Ubuntu11.04

本机平台：X86

目标平台：Loongson1B开发板

交叉编译工具链：gcc-3.4.6-2f（1B交叉编译工具链）

所需软件及工具包：

QT源码包：qt-embedded-free-3.3.7.tar.gz

TSLIB源码包：tslib-1.4.tar.gz

二、移植过程

1.安装交叉编译工具链

首先安装Loongson1B开发板提供的交叉编译工具链：

解压gcc-3.4.6-2f.tar.gz。PS.有些工具链对目录有一定的要求，请询问交叉编译工具链提供者，gcc-3.4.6-2f需要放在/home/cpu/目录下面。

#tarzxvfgcc-3.4.6-2f.tar.gz

#mvgcc-3.4.6-2f/home/cpu/

将工具链加入到PATH环境变量中：

#exportPATH=/home/cpu/gcc-3.4.6-2f/bin:$PATH

PS.每一次需要交叉编译均需要将交叉编译工具链加入到PATH变量，可通过修改/etc/profile文件来实现默认添加，即将上边最后一条语句加入到该文件中即可。

2.交叉编译TSLIB工具

解压tslib-1.4.tar.gz，进入文件夹交叉编译TSLIB工具，并指定工具安装目录为/TSLIB：

#tarzxvftslib-1.4.tar.gz

#cdtslib-1.4

#./autogen.sh

#./configure--host=mipsel-linuxac_cv_func_malloc_0_nonnull=yes

--prefix=/TSLIB

#make

#makeinstall

编译完成后，TSLIB目录需包含以下文件目录：

#ls/TSLIB

binetcincludelib

各个目录分别为TSLIB的校准及测试程序、环境配置文件、头文件、动态库。

根据1B开发板触摸屏驱动类型，配置TSLIB，修改TSLIB的环境配置文件：修改/TSLIB/etc/ts.conf，将#module_rawinput改成module_rawinput，即去掉前面的注释符。PS.这里需要注意的是module_rawinput前面不允许有空格。

3.交叉编译QT3

首先解压QT-3.3.7源码包并重命名后进入改目录以配置环境变量：

#tarzxvfqt-embedded-free-3.3.7.tar.gz

#mvqt-embedded-free-3.3.7/qt-embedded-free-3.3.7-tslib-test

#cdqt-embedded-free-3.3.7-tslib-test/

#exportQTDIR=$PWD

#exportQTEDIR=$PWD

#exportLD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH

#exportPATH=$QTDIR/bin:$PATH

执行以上步骤即可配置好QT的编译环境变量。

接下来需要修改相关的QT编译参数：

#vimmkspecs/qws/linux-mips-g++/qmake.conf

确保文件中指定的交叉编译参数为gcc-3.4.6-2f交叉编译工具链中对应gcc名称。主要修改以下标记为yellow的参数：

File：mkspecs/qws/linux-mips-g++/qmake.conf

QMAKE_MOVE =mv-f

QMAKE_DEL_FILE =rm-f

QMAKE_DEL_DIR =rmdir

QMAKE_CHK_DIR_EXISTS =test-d

QMAKE_MKDIR =mkdir-p

接下来需要为QT-3添加TSLIB触摸屏支持，对源码包进行部分修改：

首先修改src/tools/qconfig-local.h文件(不存在此文件可在该目录下创建一个同名空文件)，添加触摸屏支持：

File：src/tools/qconfig-local.h

#ifndefQT_H

#endif

#ifndefQT_DLL

#defineQT_DLL

#endif

#defineQT_QWS_IPAQ

#defineQT_QWS_IPAQ_RAW

#defineQT_NO_QWS_CURSOR

#defineQT_NO_QWS_MOUSE_AUTO

然后添加TSLIB补丁，增加QT-3对TSLIB触摸屏校正支持：

在QTDIR所在的上层目录创建一个名为tslib.patch的文件，文件内容如下：

File：../tslib.patch

Index:qt-embedded-free-3.3.4-orig/src/embedded/qmousetslib_qws.h

然后在QTDIR内执行以下命令，为QT-3添加TSLIB触摸屏校正补丁：

#cd$QTDIR

#patch-p1<../tslib.patch

最后修改src/embedded/qmouselinuxtp_qws.cpp修正正确的触摸屏设备名称。

File：src/embedded/qmouselinuxtp_qws.cpp

#ifdef

QT_QWS_IPAQ_RAW

mouseFD=open("/dev/event0",O_RDONLY)

将双引号内的设备名称改为自己的触摸屏设备名，设备名由触摸屏驱动决定。

以上几个步骤完成了对QT-3添加触摸屏支持的相关配置，接下来开始进行QT-3的交叉编译过程：

#./configure-no-cups-xplatformqws/linux-mips-g++-embeddedmips-thread-no-stl-qt-mouse-tslib-I/TSLIB/include-L/TSLIB/lib-lts-depths4,8,16,32-qvfb-prefix/usr/local/Trolltech/QtEmbedded-3.3.7-mips/

#make

TheQtlibraryisnowbuiltin./lib

TheQtexamplesarebuiltinthedirectoriesin./examples

TheQttutorialsarebuiltinthedirectoriesin./tutorial

Enjoy!-theTrolltechteam

#makeinstall

可在/usr/local/Trolltech/QtEmbedded-3.3.7-mips/目录查看到编译生成文件。

编译过程可能遇到的问题：

问题1：

/usr/bin/ld:skippingincompatible/TSLIB/lib/libts.sowhensearchingfor-lts

/usr/bin/ld:cannotfind-lts

collect2:ld返回1

make[2]:***[../../bin/moc]错误1

出错原因：找不到触摸屏动态库，编译QT的moc工具时出错，但是/TSLIB/lib/libts.so提供的是交叉编译需要的动态库。

解决方法：

#apt-getinstallqt3-dev-toolsqt3-qtconfigqt3-docqt3-designerqt3-assistantqt3-apps-dev

#cp/usr/share/qt3/bin/moc./bin/moc

问题2：

make[3]:/home/ethan/Desktop/qtmake/qt-embedded-free-3.3.7-tslib-test/bin/uic：命令未找到

出错原因：找不到编译需要的uic工具

解决方法：

#apt-getinstallqt3-dev-toolsqt3-qtconfigqt3-docqt3-designerqt3-assistantqt3-apps-dev

#cp/usr/share/qt3/bin/uic./bin/uic

其他可能问题的解决方法：

提示找不到头文件、函数未定义或者提示/usr/bin/ld:cannotfind-lxxx，其中xxx即表示函式库文件名称，其命名规则是：lib+库名(即xxx)+.so，会发生这样的原因有以下三种情形：

1.系统没有安装相对应的lib

2.相对应的lib版本不对

3.lib(.so)的symboliclink不正确，没有连结到正确的函式库文件(.so)

解决方法：

(1)先判断在/usr/lib下的相对应的函式库文件(.so)的symboliclink是否正确，若不正确改成正确的连结目标即可解决问题。

(2)若不是symboliclink的问题引起，而是系统缺少相对应的lib安装lib即可解决。

(3)如何安装缺少的lib：先搜寻相对应的LIB再进行安装

#apt-cachesearchlibxxx-dev

#apt-getinstalllibxxx-dev

若搜索到相关项，执行安装即可，若搜索不到，可上网搜索相关内容，此种错误一般很容易在网上找到解决方法。

4.QT程序移植及运行环境配置

下边将以QT自带example为例讲述移植过程：

在编译之前，需要先制定好编译的QT环境变量，为了方便使用，建议使用脚本进行配置，在程序源文件目录中新建一个qte3-path.sh的文件，内容如下：

File：./qte3-path.sh

exportQTDIR=/usr/local/Trolltech/QtEmbedded-3.3.7-mips/

exportQTEDIR=$QTDIR

exportLD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH

exportLD_LIBRARY_PATH=/TSLIB/lib:$LD_LIBRARY_PATH

exportPATH=/home/cpu/gcc-3.4.6-2f/bin:$PATH

然后执行以下命令：

#chmoda+xqte3-path.sh

#sourceqte3-path.sh

#cdqt-embedded-free-3.3.7-tslib-test/examples/widgets

#$QTDIR/bin/qmake

#make

编译成功后可在目录下找到生成的二进制可执行文件widgets，查看该二进制可执行文件相关链接库信息：

#mipsel-linux-readelf-dwidgets

Dynamicsectionatoffset0x15ccontains33entries:

标记类型名称/值

0x00000001(NEEDED)共享库：[libts-1.0.so.0]

0x00000001(NEEDED)共享库：[libqte-mt.so.3]

0x00000001(NEEDED)共享库：[libdl.so.2]

0x00000001(NEEDED)共享库：[libpthread.so.0]

0x00000001(NEEDED)共享库：[libstdc++.so.6]

0x00000001(NEEDED)共享库：[libm.so.6]

0x00000001(NEEDED)共享库：[libgcc_s.so.1]

0x00000001(NEEDED)共享库：[libc.so.6]

0x0000000f(RPATH)Libraryrpath: [/usr/local/Trolltech/QtEmbedded-3.3.7-mips/lib]

可以看到Libraryrpath即链接库目录为：

/usr/local/Trolltech/QtEmbedded-3.3.7-mips/lib

还有根据之前安装交叉编译工具链所带的基本库目录为：

/home/cpu/gcc-3.4.6-2f/mipsel-linux/lib/

我们可以在这两个目录下将运行widgets所需要的链接库文件都拷贝出来：

eg.

#cp/usr/local/Trolltech/QtEmbedded-3.3.7-mips/lib/libqte-mt.so.3.

这些*.so文件即为在Loongson1B开发板上运行QT程序widgets所需要的动态链接库文件。

接下来需要说明一下板上文件系统内QT环境参数设置问题：

上边可以看到QTLibraryrpath的路径参数为：

/usr/local/Trolltech/QtEmbedded-3.3.7-mips/lib

在开发板上，默认的QT路径即为：

/usr/local/Trolltech/QtEmbedded-3.3.7-mips/

故而我们只需要将运行QT程序需要的相关库文件及相关文件放置在此目录下，板上系统在运行QT程序时即会自动搜索此目录下的相应文件进行加载，该目录下的目录结构一般如下：

/usr/local/Trolltech/QtEmbedded-3.3.7-mips/-->

{

lib/ --> fonts

plugins --> imageformats

translations

}

lib目录用于放置运行QT程序需要的动态库文件，lib目录内的fonts用于放置QT程序需要的字体文件；

plugins用于放置运行QT程序需要加载的插件，一般情况下显示图片需要用到imageformats插件；

translations用于放置QT程序语言国际化支持的翻译文件。

而构建自己的QT文件夹，相关文件需要按照以上QT文件目录结构进行放置，需要注意的是，无论是否需要加载字体，fonts文件夹内必须存在一个名为fontdir的文件，否则运行会报错，其作用是用来辅助配置解析当前目录下的字体文件。

同时为了TSLIB触摸屏支持，我们需要将之前编译完成的TSLIB文件夹拷贝到板上的文件系统，默认存放位置为编译QT时指定的TSLIB路径。

当然我们也可以通过配置环境变量参数来改变QT目录及TSLIB目录的路径，下边列出板上设置的环境参数设置：

File：/etc/profile

...

#指定QT目录，可更改成自己的QT目录路径

exportQTDIR=/usr/local/Trolltech/QtEmbedded-3.3.7-mips

#指定中文编码格式，解决中文乱码问题，当然程序中也必须为UTF-8格式编码

exportLC_ALL=zh_CN.UTF-8

exportLANG_ALL=zh_CN.UTF-8

exportLANG=zh_CN.UTF-8

#指定TSLIB目录，可更改成自己的TSLIB目录路径

exportTSLIB_ROOT=/TSLIB

#指定相关TSLIB运行参数及设备类型

exportTSLIB_CONSOLEDEVICE=none

exportTSLIB_FBDEVICE=/dev/fb0

exportTSLIB_TSDEVICE=/dev/event0

exportTSLIB_CALIBFILE=/etc/pointercal

exportTSLIB_CONFFILE=/TSLIB/etc/ts.conf

exportTSLIB_PLUGINDIR=/TSLIB/lib/ts

exportTSLIB_TSEVENTTYPE=INPUT

#指定QT支持TSLIB触摸屏设备

exportQWS_MOUSE_PROTO=Tslib:/dev/event0

#指定QT库及TSLIB库加载路径

exportLD_LIBRARY_PATH=$QTDIR/lib:$TSLIB_ROOT/lib:/usr/local/lib:$LD_LIBRARY_PATH

#设置QT程序显示参数

exportQWS_DISPLAY="LinuxFb:mmWidth100:mmHeight130:0"

#指定QT程序加载字体路径

exportQT_QWS_FONTDIR=$QTDIR/lib/fonts

#指定QT程序加载插件路径

exportQT_PLUGIN_PATH=$QTDIR/plugins/

...

进行以上配置之后，即可在板子上运行程序，第一次使用TSLIB触摸屏，需要对触摸屏进行校准：

#$TSLIB_ROOT/bin/ts_calibrate

校准后在/etc目录下会生成一个名为pointercal的校准配置文件

#./widgets-qws

这里需要说明的是：qws的全称是Qtwindowssystem，是QT自行开发的窗口系统，体系结构类似XWindows，是一个C/S结构，由QWSServer在物理设备上显示，由QWSClient实现界面，两者通过socket进行彼此的通讯，而这里后边加的运行参数-qws是指明程序是QWSServer。
