qt-everywhere-opensource-src-5.2.0]$ vim ./qtbase/src/corelib/global/qfeatures.txt 

Building Qt 5 from Git: http://qt-project.org/wiki/Building_Qt_5_from_Git

question 1:

[leosu@localhost qt-everywhere-opensource-src-5.2.0]$ ./configure  -prefix /opt/Qt-5.2 -opensource -confirm-license -nomake tests   -skip doc   -skip svg   -no-qml-debug -release   -system-libjpeg  -system-libpng 

The test for linking against libxcb and support libraries failed!

 You might need to install dependency packages, or pass -qt-xcb.

 See src/plugins/platforms/xcb/README.

Answer:

#sudo yum install libxcb.i686   #which not work for this build

# ./configure  -qt-xcb     #this can work;

#sudo yum install libxcb libxcb-devel libXrender libXrender-devel xcb-util-wm xcb-util-wm-devel xcb-util xcb-util-devel xcb-util-image xcb-util-image-devel xcb-util-keysyms xcb-util-keysyms-devel

question 2:

[leosu@localhost qt-everywhere-opensource-src-5.2.0]$ make module-qtwebkit 

Encountered 2 configuration warning(s):

 ! QtQuick module not found, QML APIs will not be built

 ! Qt not configured to use system libpng, QImageDecoder will decode PNG images

The WebKit build was disabled for the following reasons: 

    * ICU is required. To build QtWebKit with Qt 5 you need to build Qt 5 with libICU support. Check for ICU support being mentioned in qtbase/config.summary. 

Answer:

 #sudo yum install icu.i686  libicu.i686  libicu-devel.i686   libpng-devel.i686

Question 3:

Cannot configure directfb and opengl:

Ansewer

////////opengl should has the same version to successful ./configurell

#sudo yum install ghc-OpenGL-devel.i686

#directfb-devel.i686    ////////cannot build

#download DirectFB-1.7.0 and ./configure ; make; make install;

#sudo yum install freetype-devel.i686  ftgl.i686

#sudo yum install openssl-devel.i686

Question 4: cannot find so files

[leosu@localhost domtraversal]$ ./domtraversal 

./domtraversal: error while loading shared libraries: libQt5WebKitWidgets.so.5: cannot open shared object file: No such file or directory

Answer:

第一步：确认有哪些Lib无法Load 

第二步：系统要确认动态库的地址，把动态库的路径放到/etc/ld.so.conf中 

建议：在/etc/ld.so.conf.d/上新建动态库相应的文件配置文件/etc/ld.so.conf.d/qt-leo_webkit.conf， 

在该文件中填上该动态库的绝对路径 

此例： 

sudo vim /etc/ld.so.conf.d/qt-leo_webkit.conf 

  --->>>>>> /mnt/qt_webkit/qt-everywhere-opensource-src-5.2.0/qtwebkit/lib

第三步：运行ldconfig重建/etc/ld.so.cache

    #sudo ldconfig

Question 5, cannot find or load "xcb"

[leosu@localhost domtraversal]$ ./domtraversal 

This application failed to start because it could not find or load the Qt platform plugin "xcb".

[leosu@localhost qt-everywhere-opensource-src-5.2.0]$ find . -name libqxcb.so

./qtbase/plugins/platforms/libqxcb.so

（1）将依赖的包及相应的软连接拷贝到部署机的任意目录下，并设定环境变量LD_LIBRARY_PATH，这些依赖包列表可以通过ldd命令查询

（2）无法加载插件，解决方法有如下两个

方法1：

export QT_PLUGIN_PATH=/opt/Qt5.1.1/Tools/QtCreator/bin/plugins/

export LD_LIBRARY_PATH=/opt/Qt5.1.1/Tools/QtCreator/bin/plugins/platforms:$LD_LIBRARY_PATH

将开发机器上/opt/Qt5.1.1/Tools/QtCreator/bin/plugins/platforms目录及下面的文件libqxcb.so拷贝到部署机上，并设定环境变量

方法2：qt.conf加plugins

[Paths]

Prefix=.

Plugins=plugins

在开发机器上的程序所在目录新建plugins/platforms目录，并将开发机器上/opt/Qt5.1.1/Tools/QtCreator/bin/plugins/platforms下的插件文件（libqxcb.so）拷贝过来。

均能找到插件，但仍然无法加载，提示信息如下：

This application failed to start because it could not find or load the Qt platform plugin "xcb".

Available platform plugins are: linuxfb, minimal, offscreen, xcb.

Reinstalling the application may fix this problem.

Aborted (core dumped)

（3）ldd libqxcb.so 发现xcb插件依赖的libQt5DBus.so.5找不到，目前暂时无法通过方法二来手动指定目录，只能按照方法一：

将开发机/opt/Qt5.1.1/Tools/QtCreator/lib/qtcreator目录及文件libQt5DBus.so.5拷贝到部署机上相应位置。

（4）运行程序，终于调出了界面，大功告成！综上，将程序依赖的QT库文件拷贝到部署机，并设定环境变量（见（1））；对于插件，将开发机的对应目录结构及必须文件拷贝到部署机上，并设定环境变量（见（2）和（3））。

# sudo yum install libXrender.i686  xcb-util-renderutil.i686   libXrender-devel.i686   xcb-util-renderutil-devel.i686

# sudo yum install   libxcb-devel.i686  xcb-util-devel.i686  xcb-util-keysyms-devel.i686  xcb-util-renderutil-devel.i686  libxcb.i686  libxcb.i686  xcb-util-wm-devel.i686

#sudo yum install libnice-devel.i686

#####I solved the problem. There were some packages missing. Namely libx11-xcb1 and libx11-xcb-dev. I think it’s just easier to install all packages mentioned in qtbase/src/plugins/platforms/xcb/README:

6 ,Question for Qt WebKit; xcb;   need????

webkit:

Ubuntu/Debian:

#sudo apt-get install flex bison gperf libicu-dev libxslt-dev ruby

Fedora:

#su - -c "yum install flex bison gperf libicu-devel libxslt-devel rub

Libxcb

Libxcb [xcb.freedesktop.org] is now the default window-system backend for platforms based on X11/Xorg, and you should therefore install libxcb and its accompanying packages. Qt5 should build with whatever libxcb version is available in your distro’s packages (but you may optionally wish to use v1.8 or higher to have threaded rendering support). src/plugins/platforms/xcb/README 

Fedora 17+ (xcb-util-renderutil is currently available in updates repository until it goes stable):

#su - -c "yum --enablerepo=updates install libxcb libxcb-devel xcb-util xcb-util-devel xcb-util-*-devel"

Ubuntu/Debian:

#sudo apt-get install "^libxcb.*" libx11-xcb-dev libglu1-mesa-dev libxrender-dev

Qt 5.2

Select the file according to your operating system from the list below to get the latest Qt 5.2 for your computer. The binary packages include Qt 5.2.0 libraries and Qt Creator 3.0.0

Qt Creator

Qt Creator is a cross-platform IDE (integrated development environment) tailored to the needs of Qt developers.

It is part of the Qt Project [qt-project.org]

Dependencies

The code should be easily built on any Linux distribution which has development packages for Qt installed. Below is the list of dependencies: Qt version 5.0.0 or later

gperf (v3.0 or later)

bison (v2.4.1 or later)

flex (v2.5.33 or later)

sqlite (development files)

fontconfig (development files)

xrender (development files)

phonon (development files)

libjpeg (development files)

libpng (development files)

我跑qt的directfb非OpenGL程序不会出问题，但是跑OpenGL相关的程序就会出问题，

提示：“Could not retrieve IDirectFBGL in QDirectFbWindow::glcontext()”

跟了下，是调用surface->GetGL方法时出错了。

请问是qt本身就不支持directfb的OpenGL吗？还是出了其它问题呢？

我用的是x11后端，在ubuntu10.10 PC 系统下跑的。

我跑的是qt4.8,用-qpa选项编译的， 运行时选择-platform directfb。

我确认pc上有opengl支持，因为-platform xlib时opengl的例子是可以跑起来的
