ubuntu10.10建立QT开发环境图文详解

说明：本文共分两部分，可以在阅读完该部分后点击文章后的链接进入下一部分。这个教程包含了对linux下桌面版本的Qt及Qt Creator的安装和ARM开发板上的Qt的安装过程，如果大家已经安装了桌面版本的Qt，可以跳过前面的这些内容。

一、安装g++，ubuntu默认是不带g++的，如果不安装的话，后面是无法进行桌面版的qt应用程序进行编译的，在终端中执行以下命令：

sudo apt-get install g++

二、安装arm-linux-gcc 3.3.2

我们使用的是优龙公司提供的arm-linux-gcc 3.3.2交叉编译工具链

（注：这里推荐使用友善之臂的4.4.3版本工具链，当然，这样的话你需要保证你板子上的环境也是最新的，不然编译出来的程序可能无法运行。

4.4.3工具链可以到友善之臂官网下载，也可以下载我们上传到网盘上的。）

（1）在/usr/local目录下arm目录，用于存放解压后的交叉编译工具链

sise@sise:~/sisefile/crosschain$ cd /usr/local/

sise@sise:/usr/local$ sudo mkdir arm

（2）解压交叉编译工具链

sise@sise:~$ cd sisefile/crosschain/

sise@sise:~/sisefile/crosschain$ sudo tar -jxvf cross-3.3.2.tar.bz2 -C /usr/local/arm

（3）查看目录

sise@sise:~/sisefile/crosschain$ cd /usr/local/arm/3.3.2/

sise@sise:/usr/local/arm/3.3.2$ ls

（4）添加交叉编译工具链环境变量

X方法一：

建立环境变量设置脚本：

sise@sise:/usr/local/arm/3.3.2$ sudo gedit arm-linux-gcc-3.3.2-env.sh

添加以下内容：

# add my crosschain(arm-linux-gcc-3.3.2) path

export PATH=/usr/local/arm/3.3.2/bin$:PATH

使用arm-linux-gcc 3.3.2时，可以进入存放arm-linux-gcc-3.3.2-env.sh的目录，在终端执行以下命令：

source arm-linux-gcc-3.3.2-env.sh

这样就能使arm-linux-gcc-3.3.2-env.sh生效

方法二：

修改profile文件：

sise@sise:/usr/local/arm/3.3.2$ sudo gedit /etc/profile

添加以下内容：

# add arm-linux-gcc 3.3.2 crosschain path

export PATH=/usr/local/arm/3.3.2/bin:$PATH

三、安装桌面版QT

（1）为QT增加可执行属性

sise@sise:/usr/local/arm/3.3.2$ cd /home/sise/sisefile/qt4/

sise@sise:~/sisefile/qt4$ sudo chmod +x qt-sdk-linux-x86-opensource-2010.04.bin

（2）执行qt的二进制文件：

sise@sise:~/sisefile/qt4$ ./qt-sdk-linux-x86-opensource-2010.04.bin

安装QT的过程：

这里一步要注意了，这里有提示说如果我们要使用qt，需要安装以下的文件：

提示内容：

Apart from a C++ compiler, a number of development libraries need to be present to enable Qt Creator to build your Qt applications. On Debian and Ubuntu, use the following command in a terminal to make sure they are installed:

sudo apt-get install libglib2.0-dev libSM-dev libxrender-dev libfontconfig1-dev libxext-dev

If you’re using QtOpenGL, you’ll also need OpenGL development files. You can use the following command to find out which packages to install:

sudo apt-get install libgl-dev libglu-dev

（3）安装libgl-dev libglu-dev包：

sise@sise:~/sisefile/qt4$ sudo apt-get install libglib2.0-dev libSM-dev libxrender-dev libfontconfig1-dev libxext-dev

（4）安装libgl-dev libglu-dev包：

sise@sise:/usr/local/arm/3.3.2$ sudo apt-get install libgl-dev libglu-dev

提示没有libgl-dev包

（5）安装libgl1-mesa-dev libglu-dev包：

sise@sise:/usr/local/arm/3.3.2$ sudo apt-get install libgl1-mesa-dev libglu-dev

至此桌面版的QT就安装完成了

（6）添加环境变量

添加在qcreator中环境变量（其实这一步时不需要的，因为在qt安装完成后，不需要再设置环境变量的）

找到qmake

（7）建立一个helloword工程测试：

选择qt的版本

向工程中添加一个c++文件：

在main.cpp文件中添加以下代码：

#include <QApplication>

#include <QLabel>

int main(int argc,char* argv[])

{

QApplication app(argc,argv);

QLabel* label = new QLabel(“hello world”);

label->show();

return app.exec();

}

编译

出现以下的窗口，证明我们已经完成了qt的安装：

（8）编译qvfb

qvfb是个X11模式下的qte的模拟器，没有开发板的同学可以利用qvfb来仿真qte的程序。

在安装qt的文件夹中已经包含了qvfb的工程，我们需要的是对它进行编译：

打开qvfb.pro，然后编译，出现了一下错误：

这是由于缺少了deviceskin.h和deviceskin.cpp文件，在安装qt的文件夹中同样存在这两个文件

将这两个文件复制到qvfb工程目录中

重新打开工程，编译，出现以下错误：

这是由于缺少png库，安装png库：

sise@sise:~$ sudo apt-get install libpng-dev

继续编译，又出现以下错误：

这是由于系统缺少glui和xorg库，安装glui和xorg库：

sise@sise:~$ sudo apt-get install libglui-dev

sise@sise:~$ sudo apt-get install xorg-dev

重新编译qvfb工程，出现以下窗口，这时终于成功了！

生成的文件在qt/bin目录下：

设置qvfb的环境变量：

# add qt4.6.3 for x86 path

export PATH=/home/sise/siseapp/qtsdk-2010.04/qt/bin:$PATH

四、安装qt-embedded-x86版的qt

（1）进入siseapp目录，建立qt4.6.3_embedded_x86文件夹，用来存放解压后的该版本的qt

sise@sise:~$ cd siseapp/

sise@sise:~/siseapp$ mkdir qt4.6.3_embedded_x86

（2）解压qt源文件文件，制定解压后存放的目录为刚才建立的目录：

sise@sise:~/siseapp$ cd /home/sise/sisefile/qt4/

sise@sise:~/sisefile/qt4$ tar -zvxf qt-everywhere-opensource-src-4.6.3.tar.gz -C /home/sise/siseapp/qt4.6.3_embedded_x86

（3）配置qt的编译选项：

sise@sise:~/sisefile/qt4$ cd /home/sise/siseapp/qt4.6.3_embedded_x86/qt-everywhere-opensource-src-4.6.3/

sise@sise:~/siseapp/qt4.6.3_embedded_x86/qt-everywhere-opensource-src-4.6.3$ ./configure -prefix /home/sise/siseapp/qt-embedded-4.6.3-x86 -embedded x86 -qvfb

选择 o

选择yes

（4）编译

sise@sise:~/siseapp/qt4.6.3_embedded_x86/qt-everywhere-opensource-src-4.6.3$ make

安装

sise@sise:~/siseapp/qt4.6.3_embedded_x86/qt-everywhere-opensource-src-4.6.3$ make install

在qcreator中添加刚才编译的qt版本的环境变量：

（5）重新利用该版本的qt编译helloworld工程

打开helloworld工程：

选择该版本qt的环境变量

设置run setting

我们先打开qvfb

sise@sise:~/siseapp/qt4.6.3_embedded_x86/qt-everywhere-opensource-src-4.6.3$ qvfb &

然后编译仿真，出现以下窗口，证明我们的qt又编译成功了：

五、编译安装tslib：

Tslib是一个开源的程序，能够为触摸屏驱动获得的采样提供诸如滤波、去抖、校准等功能，通常作为触摸屏驱动的适配层，为上层的应用提供了一个统一的接口。（下载tslib1.4）

（1）进入tslib存放源文件的文件夹，解压tslib：

sise@sise:~$ cd sisefile/tslib1.4/

sise@sise:~/sisefile/tslib1.4$ tar -zxvf tslib-1.4.tar.gz

（2）注：此步需要一些工具，ubuntu下需要安装automake、autoconf、libtool，可以执行下面语句安装，sudo apt-get install automake autoconf libtool，不然的话，我们是无法执行autogen.sh脚本的：

sise@sise:~/sisefile/tslib1.4$ sudo apt-get install automake autoconf libtool

（3）进入解压后的tslib文件夹，执行autogen.sh脚本文件：

sise@sise:~/sisefile/tslib1.4$ cd tslib/

sise@sise:~/sisefile/tslib1.4/tslib$ ./autogen.sh

（4）配置tslib的选项：

sise@sise:~/sisefile/tslib1.4/tslib$ ./configure –prefix=/usr/local/tslib/ –host=arm-linux ac_cv_func_malloc_0_nonnull=yes

（5）编译tslib：

sise@sise:~/sisefile/tslib1.4/tslib$ make

（6）安装tslib：

sise@sise:~/sisefile/tslib1.4/tslib$ sudo make install

（7）修改ts.conf：

sise@sise:~/sisefile/tslib1.4/tslib$ sudo gedit /usr/local/tslib/etc/ts.conf

将第二行“#module_raw input”注释去掉，变为“module_raw input”，注意一定要顶格。

（8）以下内容是在开发板的linux系统中修改的，现在由于优龙fs2410使用的cramfs文件系统是只读的，我们无法修改，这个要等到我们做出yaffs文件系统后，才能做。

打开profile：

$vi /etc/profile

添加内容如下：

export TSLIB_ROOT=/tslib
export TSLIB_TSDEVICE=/dev/event0
export LD_LIBRARY_PATH=/tslib/lib:$LD_LIBRARY_PATH
export TSLIB_FBDEVICE=/dev/fb0
export TSLIB_PLUGINDIR=/tslib/lib/ts
export TSLIB_CONSOLEDEVICE=none
export TSLIB_CONFFILE=/tslib/etc/ts.conf
export TSLIB_CALIBFILE=/etc/pointercal
export TSLIB_TSEVENTTYPE=”H3600″
export QWS_SIZE=320*240
export QWS_MOUSE_PROTO=Tslib:/dev/event0
export QWS_DISPLAY=”LinuxFb:mmWidth50:mmHeight65:0″
export POINTERCAL_FILE=/etc/pointercal
export QWS_SW_CURSOR
export QWS_KEYBOARD=”TTY:/dev/tty1″

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

六、安装arm版qt

（1）建立存放解压后的qt的文件夹

sise@sise:~/sisefile/tslib1.4/tslib$ cd /home/sise/siseapp/

sise@sise:~/siseapp$ mkdir qt-embedded-4.6.3-arm

sise@sise:~/siseapp$ mkdir qt_4.6.3_embedded_arm

（2）解压qt

sise@sise:~/siseapp$ cd /home/sise/sisefile/qt4/

sise@sise:~/sisefile/qt4$ ls

qt-everywhere-opensource-src-4.6.3.tar.gz

qt-sdk-linux-x86-opensource-2010.04.bin

sise@sise:~/sisefile/qt4$ tar -zvxf qt-everywhere-opensource-src-4.6.3.tar.gz -C /home/sise/siseapp/qt_4.6.3_embedded_arm/

（3）安装libjpeg-dev包

sise@sise:~/siseapp/qt_4.6.3_embedded_arm/qt-everywhere-opensource-src-4.6.3$ sudo apt-get install libjpeg-dev

（4）我们来查看一下qt有哪些可选的配置编译选项：

输入以下命令：

sise@sise:~/siseapp/qt_4.6.3_embedded_arm/qt-everywhere-opensource-src-4.6.3$ ./configure –help

可以看到以下的选项

[additional platform specific options (see below)]

Installation options:

These are optional, but you may specify install directories.

-prefix <dir> …… This will install everything relative to <dir>

(default /usr/local/Trolltech/Qt-4.6.3)

* -prefix-install …. Force a sandboxed “local” installation of

Qt. This will install into

/usr/local/Trolltech/Qt-4.6.3, if this option is

disabled then some platforms will attempt a

“system” install by placing default values to

be placed in a system location other than

PREFIX.

You may use these to separate different parts of the install:

-bindir <dir> ……… Executables will be installed to <dir>

(default PREFIX/bin)

(default PREFIX/lib)

-docdir <dir> ……… Documentation will be installed to <dir>

(default PREFIX/doc)

-headerdir <dir> …… Headers will be installed to <dir>

(default PREFIX/include)

-plugindir <dir> …… Plugins will be installed to <dir>

(default PREFIX/etc/settings)

-examplesdir <dir> …. Examples will be installed to <dir>

(default PREFIX/examples)

-demosdir <dir> ……. Demos will be installed to <dir>

(default PREFIX/demos)

You may use these options to turn on strict plugin loading.

-buildkey <key> …. Build the Qt library and plugins using the specified

<key>. When the library loads plugins, it will only

load those that have a matching key.

我们现在就选择要qt的编译配置，这是我选的配置，具体的作用大家可以查看上述的选项：

sise@sise:~/siseapp/qt_4.6.3_embedded_arm/qt-everywhere-opensource-src-4.6.3$ ./configure -prefix /usr/local/Trolltech/QtEmbedded-4.6.3-arm -opensource -confirm-license -release -shared -embedded arm -xplatform qws/linux-arm-g++ -depths 16,18,24 -fast -optimized-qmake -pch -qt-sql-sqlite -qt-libjpeg -qt-zlib -qt-libpng -qt-freetype -little-endian -host-little-endian -no-qt3support -no-libtiff -no-libmng -no-opengl -no-mmx -no-sse -no-sse2 -no-3dnow -no-openssl -no-qvfb -no-nis -no-opengl -no-cups -no-glib -no-xcursor -no-xfixes -no-xrandr -no-xrender -no-separate-debug-info -nomake examples -nomake tools -nomake docs -qt-mouse-tslib -I/usr/local/tslib/include -L/usr/local/tslib/lib

这里要注意的是，-qt-mouse-tslib -I/usr/local/tslib/include -L/usr/local/tslib/lib这句很重要的，这是让QT支持触摸屏，而且要使用到我们刚才编译过的tslib。

配置完成后，开始编译：

sise@sise:~/siseapp/qt_4.6.3_embedded_arm/qt-everywhere-opensource-src-4.6.3$ make

以下出现的错误是因为我使用了arm-linux-gcc 3.3.2，而qt4.6.3是需要arm-linux-gcc 4版本以上的，否则会出现语法错误。

解决：参考http://www.qtcn.org/bbs/read.php?tid=24692&fpage=0&toread=&page=1 守望者的临时解决方案:
To fix this issue patch /src/3rdparty/freetype/include/freetype/config/ftconfig.h Line 330.

（原来的为） “orr %0, %2, lsl #16\n\t” /* %0 |= %2 << 16 */
（修改后为） “orr %0, %0, %2, lsl #16\n\t” /* %0 |= %2 << 16 */

// change this line

// “orr %0, %2, lsl #16\n\t” /* %0 |= %2 << 16 */

解决：

// rect |= QRect(flowPosition, segPosition, deltaFlowPosition, deltaSegPosition);

rect = rect | QRect(flowPosition, segPosition, deltaFlowPosition, deltaSegPosition);

2890

else // flow == TopToBottom

// rect |= QRect(segPosition, flowPosition, deltaSegPosition, deltaFlowPosition);

rect = rect | QRect(segPosition, flowPosition, deltaSegPosition, deltaFlowPosition);

不过修改后虽然可以编译通过，但是还是出现了更多的语法错误。这让我发现出现这些问题是不正常的。因为不同版本的gcc对语法检查的要求是不一样的，所以我直接换用了arm-linux-gcc 4.1.2，编译不会出现以上的错误。

编译完成后，安装，在qcreator中建立该版本的qt环境变量。
