gstreamer编译gtk库

‘壹’ centOS系统在编译opencv-2.3.1的时候出现如下错误，该如何解决

root用户执行：
安装依赖包：
yum install cmake gcc gcc-c++ gtk+-devel gimp-devel gimp-devel-tools gimp-help-browser zlib-devel libtiff-devel libjpeg-devellibpng-devel gstreamer-devel libavc1394-devel libraw1394-devel libdc1394-develjasper-devel jasper-utils swig python libtool nasm -y
解压：
tar jxvf OpenCV-2.3.1a.tar.bz2
编译：
cd OpenCV-2.3.1
mkdir release
cd release
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr -D BUILD_NEW_PYTHON_SUPPORT=NO ..
make
make install

‘贰’ 虚拟机安装linux在哪找软件包如gtk+ Gstreamer+

额～～一般直接在linux的菜单下 就有软件包管理阿～～看着安装就行了～～

‘叁’ linux安装gst-ffmpeg-0.10.10 ./configure找不到gstreamer-plugins-base-0.10

sudo apt-get install libgstreamer0.10-dev(之前会报找不到libgstreamer0.10的错误)
sudo apt-get libgstreamer-plugins-base0.10-dev

ubuntu 中使用

‘肆’ 安装GTK开发环境，未满足依赖关系，如何解决

源不对，把网易镜像的源全部重新加了一遍就可以了。就是这个软件装真是多阿。。。。。

将会安装下列额外的软件包：

‘伍’ 请教，如何在arch下建立qt编译环境的问题

一、安装G++环境
sudo apt-get install build-essential
另外的一些相关环境。如果不安装,一些qt的组件是无法正常编译的,例如openGL
sudo apt-get install libx11-dev libxau-dev libxaw7-dev libxcb1-dev libxcomposite-dev libxcursor-dev libxdamage-dev libxdmcp-dev
sudo apt-get install libxext-dev libxfixes-dev libxfont-dev libxft-dev libxi-dev libxinerama-dev libxkbfile-dev libxmu-dev libxmuu-dev
sudo apt-get install libxpm-dev libxrandr-dev libxrender-dev libxres-dev libxss-dev libxt-dev libxtst-dev libxv-dev libxvmc-dev
sudo apt-get install libglib2.0-dev
sudo apt-get install libssl-dev
sudo apt-get install libgtk2.0-dev
sudo apt-get install libcups2-dev
sudo apt-get install libgl1-mesa-dev libglu1-mesa-dev
sudo apt-get install libgstreamer0.10-dev
二、解压代码
tar zxvf qt-everywhere-opensource-src-4.8.4.tar.gz
解压完进入解压后的源代码文件夹
三、执行。/configure生成makefile
。/configure -prefix /usr/local/Qt-4.8.2
（上面指定的这个目录/usr/local/Qt-4.8.2 ,就是make install 后的安装目录）
下面出现对话框选择open source edition.这是自由版。输入yes接受协议。
（1）如果你的机器各种库文件完整,经过一小会,配置完成,会出现以下信息
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/Qt-4.8.2
To reconfigure ,run ‘make confclean’ and ‘configure’
说明Makefile文件生成成功
（2）如果出现以下信息
Basic XLib functionality test failed！
You might need to modify the include and library search paths by editing
QMAKE_INCDIR_X11 and QMAKE_LIBDIR_X11 in /home/gcgily/qt-everywhere-opensource-src-4.8.4/mkspecs/linux-g++
还是老办法,以不变应万变。进config.test/x11/xlib 执行make命令,看出错信息
g++ -Wl,-O1 -o xlib xlib.o -L/usr/X11R6/lib -lXext -lX11 -lm
/usr/bin/ld： cannot find -lXext
看到了吧,g++在/usr/X11R6/lib下,找不到libXext.so呢。
其原因就在于需要安装libX11的开发包,在Ubuntu/debian里包名都是libX11-dev
根据以往的经验,在。/configure前主动装好下面3个包,基本上就万事大吉了
sudo apt-get install libX11-dev libXext-dev libXtst-dev
安装所需到包后再重新。/configure即可生成Makefile文件
如果出现：Project ERROR： Package gstreamer-app-0.10 not found,则执行以下命令
apt-get install libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev如果出现 ： g++： error： unrecognized command line option ‘-fuse-ld=gold’
这是Qt的一个bug：https://bugs.webkit.org/show_bug.cgi？id=89312
在装有gold linker的系统里,编译脚本会加入-fuse-ld=gold选项,但这个选项gcc是不支持的。解决办法是移除该选项,找到文件src/3rdparty/webkit/Source/common.pri,屏蔽QMAKE_LFLAGS+=-fuse-ld=gold。
#
QMAKE_LFLAGS+=-fuse-ld=gold
四、编译QT
执行make命令,需要2个小时。
五、安装QT
运行sudo make install命令。需要几分钟时间,默认安装到/usr/local/Qt-4.8.2. 运行/usr/local/Qt-4.5.3/bin/designer ,若能启动QT,说明QT已经安装好了。
六、设置环境变量
更改用户环境变量
gedit /home/username/.bashrc
添加：
export QTDIR=/usr/local/Qt-4.8.2
export PATH=$QTDIR/bin：$PATH
export MANPATH=$QTDIR/man：$MANPATH
export LD_LIBRARY_PATH=$QTDIR/lib：$LD_LIBRARY_PATH
更改包括root用户的环境变量
sudo gedit /etc/profile （此处profile文件要更改一下权限才能写入）
添加：
export QTDIR=/usr/local/Qt-4.8.2
export PATH=$QTDIR/bin：$PATH
export MANPATH=$QTDIR/man：$MANPATH
export LD_LIBRARY_PATH=$QTDIR/lib：$LD_LIBRARY_PATH
七、测试环境变量
重启测试环境变量：
qmake -v
显示版本信息：
QMake version 2.01a
Using Qt version 4.8.2 in /usr/local/Qt-4.8.2/lib
which qmake
显示安装位置信息：
/usr/local/Trolltech/Qt-4.8.2/bin/qmake
环境变量设置成功。
代码：
如果需要在Qt中引用其他的包以及库文件,则使用：
INCLUDEPATH += /usr/local/include/
INCLUDEPATH += /usr/local/include/Eigen
INCLUDEPATH += /usr/local/include/boost
INCLUDEPATH += /usr/local/include/CGAL
LIBS += -L/usr/local/lib/ -lgmp
LIBS += -L/usr/local/lib/ -lmpfr
其中LIBS参数中 -l后只能接特定某一个库文件,且如果该文件为 “libxxx.so“,则-l后只接“xxx”。
上面就是搭建Qt开发环境的方法介绍了,作为一个良好的跨平台开发工具,Qt能够很好的运行于更大主流系统,拥有丰富的API等。
