QT-embedded-4.5 for arm的安装和使用 [复制链接]

以下是详细的安装过程，如果想避免漫长的编译过程，可以下载已经编译安装好的压缩包QtEmbedded-4.5.1-arm.tar.gz，解压缩到/usr/local/Trolltech目录下（若无Trolltech则创建此目录），直接从step3开始。

# tar zxvf QtEmbedded-4.5.1-arm.tar.gz -C /usr/local/Trolltech

完整安装过程：

step1. 将qt-embedded-linux-opensource-src-4.5.1.tar.gz拷贝到Linux下，解压缩：

# tar zxvf qt-embedded-linux-opensource-src-4.5.1.tar.gz

# cd qt-embedded-linux-opensource-src-4.5.1

修改qt-embedded-linux-opensource-src-4.5.1/src/gui/embedded/qmouselinuxtp_qws.h，在头文件处加入：

#define QT_QWS_IPAQ

#define QT_QWS_IPAQ_RAW

step2. 配置选项并安装，也可以下载安装脚本qte_for_arm.sh：

#./configure \

-embedded arm \

-qt-sql-sqlite \

-plugin-sql-sqlite \

-no-scripttools \

-no-nis \

-exceptions \

-xmlpatterns \

-no-largefile \

-no-libmng \

-no-accessibility \

-depths 16 \

-nomake docs \

-make tools \

-make libs \

-qt-zlib \

-feature-THREAD \

-feature-CONCURRENT \

-feature-SOUND \

-feature-EFFECTS \

-feature-QWS_MULTIPROCESS \

-silent > log_cfg 2>&1

#make && make install

step3. 设置环境变量（两种方法）：

仅当前用户有效（其他用户无效）：修改$HOME/.bash_profile,加入：

PATH=/usr/local/Trolltech/QtEmbedded-4.5.1-arm/bin:$PATH

立即生效：

#source $HOME/.bash_profile

所有用户有效（包括root和普通用户）： 修改/etc/profile,加入以下行（一般在最后一行添加）：

export PATH=/usr/local/Trolltech/ QtEmbedded-4.5.1-arm/bin:$PATH

立即生效：

#source /etc/profile

step4. 要移植Qt-embedded到开发板上，需要拷贝的Qte基本库文件、图片插件库和字体文件：

1) QtEmbedded-4.5.1-arm/lib/libQtGui.so.4.5.1

2) QtEmbedded-4.5.1-arm/lib/libQtNetwork.so.4.5.1

3) QtEmbedded-4.5.1-arm/lib/libQtCore.so.4.5.1

4) QtEmbedded-4.5.1-arm/lib/libQtSql.so.4.5.1

5) QtEmbedded-4.5.1-arm/plugins/imageformats

6) QtEmbedded-4.5.1-arm/lib/fonts

在Linux PC上建立文件夹，将上述文件拷入：

#mkdir opt qt lib plugins

#mv plugins qt

#mv lib qt

#mv qt opt

#cp /usr/local/Trolltech/QtEmbedded-4.5.1-arm/lib/libQtGui.so.4.5.1 opt/qt/lib

#cp /usr/local/Trolltech/QtEmbedded-4.5.1-arm/lib/libQtNetwork.so.4.5.1 opt/qt/lib

#cp /usr/local/Trolltech/QtEmbedded-4.5.1-arm/lib/libQtCore.so.4.5.1 opt/qt/lib

#cp /usr/local/Trolltech/QtEmbedded-4.5.1-arm/lib/libQtSql.so.4.5.1 opt/qt/lib

#cp /usr/local/Trolltech/QtEmbedded-4.5.1-arm/plugins/imageformats opt/qt/plugins

#cp /usr/local/Trolltech/QtEmbedded-4.5.1-arm/lib/fonts opt/qt/lib

然后创建库链接：

ln -s opt/qt/lib/libQtGui.so.4.5.1 opt/qt/lib/libQtGui.so.4

ln -s opt/qt/lib/libQtCore.so.4.5.1 opt/qt/lib/libQtCore.so.4

ln -s opt/qt/lib/libQtNetwork.so.4.5.1 opt/qt/lib/libQtNetwork.so.4

ln -s opt/qt/lib/libQtSql.so.4.5.1 opt/qt/lib/libQtSql.so.4

step5. 将opt/qt 加入到开发板根文件系统 中，然后通过tftp方式将此根文件系统烧写进开发板。

step6. 在开发板上设置环境变量：

#export set QTDIR=/opt/qt

#export PATH=$QTDIR:$PATH

#export LD_LIBRARY_PATH=$QTDIR/lib:$QTDIR/plugins/imageformats:$LD_LIBRARY_PATH

#export QT_PLUGIN_PATH=$QTDIR/plugins/

#export QT_QWS_FONTDIR=$QTDIR/lib/fonts

#export set QWS_MOUSE_PROTO=LinuxTP:/dev/h3600_tsraw

step7. 初次使用触摸屏还需要校正，到安装源目录qt-embedded-linux-opensource-src-4.5.1/examples/qws/mousecalibration下

#qmake -project

#qmake

#make

将生成的mousecalibration拷到开发板上运行，进行五点校正。

step8. 将Qt-Embedded程序运行在目标板上： 用Qt-Embedded for arm的库编译Qt-Embedded应用程序，以demo为例，确保qmake是来自/usr/local/Trolltech/QtEmbedded-4.5.1-arm/bin：

# qmake -project

# qmake

# make

将得到的demo程序下载到目标板上，在运行程序前以下环境变量必须已经设置：

export QTDIR=/opt/qt:$QTDIR

export PATH=$QTDIR:$QTDIR/plugins:$PATH

export LD_LIBRARY_PATH=$QTDIR/lib:$QTDIR/plugins/imageformats:$LD_LIBRARY_PATH

export set QWS_MOUSE_PROTO=LinuxTP:/dev/h3600_tsraw

export QT_PLUGIN_PATH=$QTDIR/plugins/

export QT_QWS_FONTDIR=$QTDIR/lib/fonts

export QWS_DISPLAY=LinuxFb:/dev/fb0

export QWS_DISPLAY="LinuxFb:mmWidth100:mmHeight130:0"

export QWS_SIZE=800x480

然后在目标板的终端上输入：

#./demo -qws

即可运行。

太感谢了！顺便问一下，那可以下载到已经编译好的压缩包。

唔，在公司的服务器上。。。

我已经按楼上的一步步地做了

在编译 demos 出现了以下错误：


好慢啊，今天花了一个下午把  Qt -embedded 编译好了

在编译demos 时发现错误：

望楼主能看一下，非常感谢！

QSqlRelationalDelegate error,可能是跟数据库有关。是在configure的时候一起编译的demos还是都编译好后才编的？

我记得我好像是-nomake-demos。如果我需要跑跑demos，再单独编哪个例子。

在Makefile里加入-I/usr/local/Trolltech/QtEmbedded-4.5.1-arm/include/QtSql
-lQtSql

看看有用没。

在编译Qt-embedded 时
我所用的参数是：

${BUILD_PATH}/${QTE_VERSION}/configure \
        -embedded arm \
        -qt-sql-sqlite \
        -plugin-sql-sqlite \
        -no-scripttools \
        -no-nis \
        -exceptions \
        -xmlpatterns \
        -no-largefile \
        -no-libmng \
        -no-accessibility \
        -depths 16 \
        -nomake docs \
        -make tools \
        -make libs \
        -qt-zlib \
        -feature-THREAD \
        -feature-CONCURRENT \
        -feature-SOUND \
        -feature-EFFECTS \
        -feature-QWS_MULTIPROCESS \
        -silent


编完后，然后进入demos目录编译
按你的方式加了，还是不行

在Makefile 里加入

INCPATH += -I/usr/local/Trolltech/QtEmbedded-4.5.1-arm/include/QtSql

这一步编译能够通过，不过接下来又有问题了

好像找不到  QtOpenGL 这个库？

谢谢

本人用的是 QtEmbedded-4.5.1-arm.tar.gz

你不能把所有的demo一块编啊，你编译qt的时候可是去了很多选项的。

我是configure的时候不要demos，安装好后设置qmake环境变量，然后进入安装目录下的examples:

#cd /tmp/qt-embedded-linux-opensource-src-4.5.1/examples/dialogs/findfiles

这个例子比较简单，需要的条件不多，直接qmake -project ;qmake; make 就行了。

编译demos和example要小心环境变量qmake，安装的时候是qt3的qmake，装好后要换成qte的qmake。

安装的时候是qt3的qmake，装好后要换成qte的qmake????
安装的时候怎么看用的是qt3的qmake??

qmake -v

编译Qt-embedded 怎么这么难啊

郁闷啊

按楼主的方法，编个基本的程序也不行啊
不是这个错，就是那个错，

哎

.......

你可以多google些安装帖子，综合起来看

再说了，应该先确定需求，会需要什么库，就编译哪个选项，所谓的裁减么。你想简单干脆直接 ./configure。

原先用

qmake -project
qmake

产生Makefile 文件

能正常检测出arm-linux-gcc

现在却检测不出来了
采用了gcc选项，只能采用手动改，不知道为什么

而且 examples 目录下基本是编译不过的

在编译  examples/desktop 例子时：
出现如下错误，楼主能帮我看一下吗？
谢了：

第一次搞qt 真得很不容易啊，感觉

我把desktop下的screenshot目录拷贝到/usr/local/Trolltech/QtEmbedded-4.5.1-arm下，qmake -project; qmake ;make编译通过。
建议不要一编一大片，需要哪个例子就编哪个。

注：我也是编译desktop出现同样的错误，所以我就进去编一个例子了。

这个可以 编译通过，不过把编译好的binary文件下载到
板子(MW2440)上还是跑不起来的。

错误提示如下:

唔，拜托，运行的时候要加 -qws 你还是没仔细看过我的帖子啊。。。。

呵呵，不好意思啊。

我现在在我平台装了两个qt-embedded, 一个是 for x86的，用qvfb模拟framebuffer, 另外一个是for arm版的

我写了一个基本的helloWorld.cpp

#include <qapplication.h>
#include <qlabel.h>

int main(int argc, char **argv)
{
    QApplication app(argc, argv);

    QLabel *label=new QLabel("Hello Qt");

    label->setGeometry(10,10,200,80);

    label->show();
    return app.exec();

}

在主机端和 arm开发板上都能正常运行，区别是arm开发板能支持usb鼠标，不过目前还不支持光标，操作起来有点困难。
在开发板上会显示一个对话框窗口，绿色背景的。




然后我用同样的方法编译   examples/desktop/screenshot/  例子，会在该目录下生成screenshot 可执行文件（一个是elf for x86, 一个是 elf for arm）

在主机端（x86版）运行
./screenshot -qws
能够正常运行



但是在arm开发板上运行却
报如下错误，是不是没有考什么库啊？
bash-4.0# ./screenshot -qws
./screenshot: symbol lookup error: ./screenshot: undefined symbol: _ZN7QWidget9dropEventEP10QDropEvent
bash-4.0# udevd-event[2419]: rmdir(//dev) failed: Device or resource busy

udevd-event[2417]: rmdir(//dev) failed: Device or resource busy


bash-4.0#


请楼主在再帮我分析一下是什么问题，谢了。

我的板子上空间不够了，所以用nfs挂载了pc上的/usr/local/Trolltech/QtEmbedded-4.5.1-arm 到/mnt/hd

export PATH=/mnt/hd:/bin:/usr/bin:/usr/local/bin:$PATH

export LD_LIBRARY_PATH=/mnt/hd/lib:/lib:/usr/lib:/usr/local/lib:$LD_LIBRARY_PATH

export set QWS_MOUSE_PROTO=LinuxTP:/dev/h3600_tsraw
export QT_PLUGIN_PATH=/mnt/hd/plugins
export QT_QWS_FONTDIR=/mnt/hd/lib/fonts
export QWS_DISPLAY="LinuxFb:mmWidth100:mmHeight130:0"


在板子上运行/mnt/hd/demos/screenshot/screenshot -qws

没有错误，正常运行了。

我在板子上运行Qtembedded for x86编译的screenshot，错误是：
line 1: syntax error: "(" unexpected


你的错误还是头一次见到，关rmdir什么事呢？？一个删除目录的命令 - -!

不过  “./screenshot: symbol lookup error” 我感觉和环境变量的有关。我先吃饭啊，一会再看看。

我用的是nfs boot方式，

我把/usr/local/Trolltech/QtEmbedded-4.5.1-arm/ 的所有文件拷到 rootfs 目录下，
然后修改 rcS文件如下：


#export set QTDIR=/opt/qt
export set QTDIR=/QtEmbedded-4.5.1-arm
export PATH=$QTDIR:$PATH
export LD_LIBRARY_PATH=$QTDIR/lib:/lib:/usr/local/lib:$QTDIR/plugins/imageformats:$LD_LIBRARY_PATH
export QT_PLUGIN_PATH=$QTDIR/plugins
export QT_QWS_FONTDIR=$QTDIR/lib/fonts
export set QWS_MOUSE_PROTO=LinuxTP:/dev/h3600_tsraw
export QWS_DISPLAY=LinuxFb:/dev/fb0
export QWS_DISPLAY="LinuxFb:mmWidth100:mmHeight130:0"
export QWS_SIZE=480x272


结果还是不行，还是只有我那个helloWorld程序可以跑。

bash-4.0# ./screenshot -qws
./screenshot: symbol lookup error: ./screenshot: undefined symbol: _ZN7QWidget9dropEventEP10QDropEvent
bash-4.0# udevd-event[2301]: rmdir(//dev) failed: Device or resource busy

udevd-event[2303]: rmdir(//dev) failed: Device or resource busy



Btw,  楼主在开发板上有没有移植成功Qtopia啊？

我的最终目标是移植Qtopia, 不过现在连这一步还没有迈过去。

神啊，救救我吧。

楼主你用的gcc 版本是多少？

晤，arm-linux-gcc 3.4.1，扬创2440开发板。

Qtopia和QtEmbedded不一样啊，Qtopia是完整的桌面环境。你要是用Qtopia直接下个装了，不用装QtEmbedded。


我的QtEmbedded-4.5.1-arm/ 下所有东西加起来有131M呢，你全拷到板子上了？？


用screenshot的绝对路径运行看看呢？就是/usr/local/Trolltech/QtEmbedded-4.5.1-arm/demos/screeshot/screenshot -qws这样。

.......

我用的是 gcc4.4.0 估计跟这个有关，好像网上能成功的都是用gcc3.4.1啊，这个版本太老了。


我一开始就是下Qtopia直接编译的啊，不过就是跑不起来啊：
