君正4750开发板使用日记4-QT Embedded、Tslib、QT for VS2008的...

QT Embedded、Tslib、QT for VS2008的配置与编译

Linux下常用的图形开发库有QT/GTK/MiniGUI等，我这里是选用了QT了。QT可以跨平台编译，同一份代码可以在WINDOWS、 UBUNTU LINUX和MIPS LINUX下编译，因此我们可以在WINDOWS下编写调试程序，再到UBUNTU下交叉编译MIPS的目标程序。

首先是去NOKIA的网站下载QT源码和工具了，下哪个版本自己决定，具体过程不多说。我下载的是qt-embedded-linux- opensource-src-4.5.3.tar.gz、qt-win-opensource-4.6.1-vs2008.exe和qt-vs- addin-1.1.3.exe。如果你一直在LINUX下工作，你可以下载x11的版本。而像我这样在WINDOWS下的话就只需要qt- embedded和VS的版本就可以了。

首先我还是将qt-embedded打包成ISO挂到UBUNTU虚拟机的CDROM上解压，并重命名为qte453：
root@ubuntu :/# mount /dev/cdrom /mnt
mount: block device /dev/sr0 is write-protected, mounting read-only
root@ubuntu :/# ls /mnt
qt-embedded-linux-opensource-src-4.5.3.tar.gz  qt-x11-opensource-src-4.5.3.tar.gz
qt-extended-opensource-src-4.4.2.tar.gz        tslib-1.4.tar.gz
root@ubuntu :/# cd /opt
root@ubuntu :/opt# tar -xf /mnt/qt-embedded-linux-opensource-src-4.5.3.tar.gz
root@ubuntu :/opt# ls
hello    linux-2.6.24.3               qt-embedded-linux-opensource-src-4.5.3
hello.c  mipseltools-gcc412-glibc261  u-boot-1.1.6
root@ubuntu :/opt# mv qt-embedded-linux-opensource-src-4.5.3 qte453
root@ubuntu :/opt# ls
hello  hello.c  linux-2.6.24.3  mipseltools-gcc412-glibc261  qte453  u-boot-1.1.6
root@ubuntu :/opt# cd qte453
root@ubuntu :/opt/qte453# ls
bin            demos     include             LICENSE.GPL3  qmake   translations
changes-4.5.3  doc       INSTALL             LICENSE.LGPL  README
config.tests   examples  LGPL_EXCEPTION.txt  mkspecs       src
configure      FAQ.txt   lib                 projects.pro  tools
root@ubuntu :/opt/qte453#

接着配置交叉编译的环境：
root@ubuntu :/opt/qte453# export PATH=/opt/mipseltools-gcc412-glibc261/bin:$PATH
root@ubuntu :/opt/qte453# export LD_LIBRARY_PATH=/opt/mipseltools-gcc412-glibc261/lib

然后准备进行configure。查资料可知君正4750的目标平台类型应该是linux-mips-g++，但我们用的编译工具其实是linux-mipsel-g++之类的，多了个el，因此需要修改一下配置文件：
root@ubuntu :/opt/qte453# find -name linux-mips-g++
./mkspecs/qws/linux-mips-g++
root@ubuntu :/opt/qte453# cd mkspecs/qws/linux-mips-g++/
root@ubuntu :/opt/qte453/mkspecs/qws/linux-mips-g++# ls
qmake.conf  qplatformdefs.h
root@ubuntu :/opt/qte453/mkspecs/qws/linux-mips-g++# vi qmake.conf

在VI里把所有“mips-linux-”替换为“mipsel-linux-”，保存退出：

#
# qmake configuration for building with mipsel-linux-g++
#

include(../../common/g++.conf)
include(../../common/linux.conf)
include(../../common/qws.conf)

# modifications to g++.conf
QMAKE_CC                = mipsel-linux-gcc
QMAKE_CXX               = mipsel-linux-g++
QMAKE_CFLAGS           += -mips32
QMAKE_CXXFLAGS         += -mips32
QMAKE_LINK              = mipsel-linux-g++
QMAKE_LINK_SHLIB        = mipsel-linux-g++

# modifications to linux.conf
QMAKE_AR                = mipsel-linux-ar cqs
QMAKE_OBJCOPY           = mipsel-linux-objcopy
QMAKE_STRIP             = mipsel-linux-strip

load(qt_config)

root@ubuntu :/opt/qte453/mkspecs/qws/linux-mips-g++# cd ..
root@ubuntu :/opt/qte453/mkspecs/qws# cd ../..
root@ubuntu :/opt/qte453#

接下来我们作一个简单的 configure.configure有很多参数，可以用--help命令查看到；另外如果你不是第一次配置，应先执行make confclean清理一下；configure会首先编译qmake，如果qmake都编译不成功，则你需要到qmake目录去清理一下；编译成功后， 默认安装目录是/usr/local/Trolltech/QtEmbedded-4.5.3-mips，可在configure时加-prefix参数 修改之.

root@ubuntu :/opt/qte453# ./configure -embedded mips -xplatform qws/linux-mips-g++ -little-endian -host-little-endian

Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into /usr/local/Trolltech/QtEmbedded-4.5.3-mips

To reconfigure, run 'make confclean' and 'configure'.

反正后面是一大堆日志了，大概好几分钟后完成，这时Makefile已经创建好了，可以执行make进行编译了，这个需要时间更久，大概要大半小时。

过了一会，失败了，提示找不到zlib.h，是因为没安装zlib，装一下，重新make：

漫长的等待后，make完成，可以执行安装：

root@ubuntu :/opt/qte453# make install

...

一行行字幕飞过，很快安装完成。

由于我们的开发板根目录是在/nfsroot/root-jz-20090216/，因此其实需要安装到/nfsroot/root-jz-20090216/usr/local/Trolltech/QtEmbedded-4.5.3-mips下：
root@ubuntu :/opt/qte453# cd /
root@ubuntu :/# mkdir -p /nfsroot/root-jz-20090216/usr/local/Trolltech
root@ubuntu :/# cd /nfsroot/root-jz-20090216/usr/local/Trolltech/
root@ubuntu :/nfsroot/root-jz-20090216/usr/local/Trolltech# cp /usr/local/Trolltech/QtEmbedded-4.5.3-mips . -r
root@ubuntu :/nfsroot/root-jz-20090216/usr/local/Trolltech# cd /
root@ubuntu :/#

这时，我们可以写一个QT的helloworld来测试一下：
root@ubuntu :/# cd ~
root@ubuntu :~# mkdir qthello
root@ubuntu :~# cd qthello/
root@ubuntu :~/qthello# vi qthello.cpp

输入以下内容，保存退出：

#include <QApplication>
#include <QLabel>
#include <QFont>

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

        QLabel *label = new QLabel("Hello Qt on JZ4750!");
        label->setFont(QFont("Times",36,QFont::Bold));
        label->show();
        int res=app.exec();
        delete label;
        return res;
}

注意要有设置字体的代码，不然的话运行起来会很小，基本上要用放大镜才能看见。

然后进行编译链接：

root@ubuntu :~/qthello# /usr/local/Trolltech/QtEmbedded-4.5.3-mips/bin/qmake -v
QMake version 2.01a

root@ubuntu :~/qthello# ls

root@ubuntu :~/qthello#

完成后，将编译的结果程序复制到开发板NFS根目录：
root@ubuntu :~/qthello# cp qthello /nfsroot/root-jz-20090216/
root@ubuntu :~/qthello#

然后在开发板COM终端上直接输入以下命令运行：
[email protected]:/# /qthello -qws

运行成功，大概过几十秒就应该能看到界面了（QT编译的东西太多，速度不是一般的慢）。

接下来说一下TSLIB和QT VS2008的配置（理论上应该先编译TSLIB再编译QT）。这两个在网上也有很多资料介绍了，没什么特别的。

解压编译TSLIB（需要先安装autoconf和libtool，apt-get install autoconf libtool）：

#undef rpl_malloc

root@ubuntu :/opt/tslib# make install

我这个配置是安装在/opt/tsemb下，使用时应把所有文件COPY到开发板相应目录：
root@ubuntu :/opt/tslib# cd /opt/tsemb/
root@ubuntu :/opt/tsemb# ls
bin  etc  include  lib
root@ubuntu :/opt/tsemb# mkdir -p /nfsroot/root-jz-20090216/opt/tsemb
root@ubuntu :/opt/tsemb# cp . /nfsroot/root-jz-20090216/opt/tsemb/ -r
root@ubuntu :/opt/tsemb#

然后在开发板COM终端上运行/opt/tsemb/bin里的ts_calibrate程序进行校准测试，并修改/etc/profile.d /tslib.sh以改正环境变量（TSLIB_ROOT=/opt/tsemb，export QWS_MOUSE_PROTO=tslib:/dev/ts），具体不细述了。

QTE要使用同一个TSLIB的话，需要重新配置编译，在configure时加参数：-qt-mouse-tslib -I/opt/tsemb/include -L/opt/tsemb/lib。所以我前面说理论上应先编译TSLIB较好。

而至于WINDOWS下VS2008的QT安装就容易很多了，下载了qt-win-opensource-4.6.1-vs2008.exe和 qt-vs-addin-1.1.3.exe，直接双击运行安装，完成后在VS2008里会多一个QT菜单，执行Qt/QtOptions设置添加一下 QT 4.6.1的安装路径即可，新建VS项目的窗口中会多出 一项Qt4 Projects。也可以执行Qt/Open Qt project file(*.pro)打开QT格式的项目并转换为VC项目。新建项的窗口中也会多出Qt Forms和Qt Resources。双击UI文件的话会调用QtCreator的设计界面。代码在VS2008里编写调试通过后，复制到Linux主机上进行交叉编译即 可发布到开发板上使用。

如果VC的代码自动完成提示功能不可用，可尝试以下办法：在 工具｜选项｜项目和解决方案｜VC++目录｜Win32｜包含文件 中添加QT的INCLUDE目录然后重启VC；UI文件修改后要重新编译一次；把工程下的NCB文件删除再重新编译工程。

另外有一个不需要VS2008的独立版本，跟LINUX下的QtCreator是一模一样的，兼容性会更好一些。

至此基本上君正4750开发板的整个开发环境已基本搭建完成。
