    启动KDE4的应用程序和会话

    当您开始KDE4的开发时,通常您可以有这样三个选择:


    随后的章节描述的就是这三种选择。

    Note
    如果您在运行任何KDE4应用程序时遇到错误,例如:
     Qt: Session management error: Could not open
    network socket
    

    (会话管理错误:打不开套接字)

     QMutex::lock: Deadlock detected in thread
    -1241241936 
    

    (在线程-1241241936中侦测到死锁)

    或者卡在运行startkde的时候,请阅读这篇文章来绕过这个问题。


    启动KDE4应用程序

    在普通的shell里使用sux

    使用这个方法需要sux工具 (http://fgouget.free.fr/sux/sux-readme.shtml)。sux工具在大多数发行版上是可用的。当然你也可以参考下一篇 normal shell without sux 的文档。sux可以让您用一种干净而简洁的方式在切换到其他用户帐号时隐式地管理X转发(认证和显示输出)。

    登录时请输入

    sux - kde-devel
    

    您的.bashrc脚本将帮助您正确地设置全部环境变量和其他相关配置。如果要启动一个应用程序,只需简单地输入程序名称;例如

    kwrite
    
    Note
    如果您遇到诸如MIME类型丢失的错误,请尝试:
    • 运行
      unset XDG_DATA_DIRS ; kbuildsycoca4
      


    在shell里不用SUX

    启动KDE 4应用程序最简单的方法是用su作为kde-devel用户登录,然后从命令行简单启动。登录,输入

    su - kde-devel
    

    然后,输入你的密码

    export DISPLAY=:0
    
    Note
    导入DISPLAY 变量是必须的,这样KDE4程序才能在KDE3桌面显示并运行.

    所有的环境变量和其他设置应该参照下面的连接设置正确 .bashrc. 如果想要启动一个程序其实很简单,只是需要输入程序的名字就可以了; 例如

    kwrite
    
    Note
    如果你得到丢失mimetypes此类的错误, 试一试下面的方法:
    • run
      unset XDG_DATA_DIRS ; kbuildsycoca4
      
    Note
    如果你得到不能连接X服务器的错误, 注意一普通KDE 3 用户执行:
    sudo xhost +local:kde-devel
    

    ;确保应用程序可以连接到当前 X 会话。

    Although your X server should accept incoming TCP connections, this is often switched off as a distribution default (like with Kubuntu Feisty). When using kdm you must edit /etc/kde3/kdm/kdmrc as root and make sure it does not contain:

    ServerArgsLocal=-nolisten tcp
    

    Once you have fixed this, you will need to restart your X server. The xhost command should no longer return an "unable to open display" error.

    For convenience, you should put this in the Autostart of your regular user. To do this, create a new file in the $HOME/.kde/Autostart directory of your regular user with the following content:

    #! /bin/sh
    xhost +local:kde-devel
    

    确保新文件是可执行的,对他执行chmod +x

    If you'd like to find out more about the security issues involved with using xhost,详见此文


    使用SSH

    The simplest way to run a KDE 4 application with SSH in your current desktop environment is to get an X-aware shell prompt as the kde-devel user like this:

    ssh -X kde-devel@localhost
    

    现在可以按正常方法启动KDE应用了,例如:

    kwrite
    

    The two lines can be conveniently combined:

    ssh -X kde-devel@localhost kwrite
    
    Note
    如果碰到问题,参考上面的出错处理。


    无密码登录

    使用前,无密码登录必须要有相应设置。以普通桌面用户运行下列命令:

    ssh-keygen -t rsa
    

    连续三次回车以接受这个路径~/.ssh/id_rsa,不填任何东西。Now, copy the single line in ~/.ssh/id_rsa.pub that's printed after running this command:

    cat ~/.ssh/id_rsa.pub
    

    After that line is copied, ssh back into the kde-devel user and put the copied line in the file $HOME/.ssh/authorized_keys:

    ssh -X kde-devel@localhost $HOME/kde/bin/kwrite \
     $HOME/.ssh/authorized_keys
    

    Paste in the line, save the file, and quit KWrite. Now try running KWrite again with the same SSH command; you shouldn't have to enter a password anymore:

    ssh -X kde-devel@localhost $HOME/kde/bin/kwrite
    
    Warning
    无密码SSH登录有一定 安全隐患,取保你~/.ssh/id_rsa文件的安全性,要限制接触可以做如下操作:
    chmod og-xrw ~/.ssh/id_rsa
    
    (创建前要有些读写权限)


    SSH桌面文件

    If you want to be able to launch apps more easily than running them with an SSH command from the command line, one way is to create .desktop files that ssh into the other account.

    Note
    This will only be useful if your desktop environment supports .desktop files, but at least KDE and GNOME do.


    You can start with an existing .desktop file as a template (like one from your desktop) or you can make one from scratch. The main idea is to prefix the command being run with this string:

    ssh -X kde-devel@localhost $HOME/kde/bin/
    

    一个运行KWrite的(.desktop)文件通常有下列内容:

    [Desktop Entry]
    Categories=Qt;KDE;TextEditor;
    Comment=
    DocPath=kwrite/index.html
    Encoding=UTF-8
    Exec=ssh -X kde-devel@localhost /home/kde-devel/kde/bin/kwrite %U
    GenericName=Text Editor
    Icon=kwrite
    InitialPreference=8
    MimeType=text/plain
    Name=KWrite (kde-devel)
    Path=
    StartupNotify=false
    Terminal=false
    TerminalOptions=
    Type=Application
    X-DBUS-StartupType=Multi
    X-DCOP-ServiceType=non
    X-KDE-StartupNotify=true
    X-KDE-SubstituteUID=false
    X-KDE-Username=
    
    Tip
    Apps launched using SSH like this don't trigger the correct launch responses, so you probably want to disable "launch feedback" for your .desktop files


    Note
    In order to create a .desktop file for a KDE 4 app by using this pattern, the app's package will have to have been installed into ~/kde/bin using the cmakekde command


    加载KDE 4会话

    嵌套 KDE 4会话

    Nested

    Instead of using a full-blown new virtual X for developing software you can use Xephyr to embed your KDE 4 session into your working KDE 3 or other X11 environment.

    You can also do this with xnest, but as xnest cannot handle extensions like Render many people prefer Xephyr.

    If you want to get a minimal KDE session up and running, just launch Xephyr (available in Kubuntu as xserver-xephyr; Gentoo users compile x11-base/xorg-server with USE="kdrive"):

    Xephyr :1&
    

    加载KDE:

    export DISPLAY=:1
    /path/to/kde4/bin/startkde-modified &
    

    startkde-modified is a copy of the startkde-script which includes the following lines on the top:

    export KDEDIR=`kde4-config --prefix`
    export LD_LIBRARY_PATH=$KDEDIR/lib
    export PATH=$KDEDIR/bin/:$PATH
    export KDEHOME=~/.kde4
    

    可以在KDM上通过Xdmcp协议使用Xephyr,创建一个新的KDE 4连到KDM。

    在Kubuntu上, 可以这么做

    [Xdmcp]
    # Whether KDM should listen to incoming XDMCP requests.
    # 缺省是 true
    Enable=false
    

    in /etc/kde3/kdm/kdmrc to

    [Xdmcp]
    # Whether KDM should listen to incoming XDMCP requests.
    # 缺省是 true
    Enable=true
    

    and adjust your /etc/kde3/kdm/Xaccess to allow your local machine access. Additionally you should make sure to set up a port blocking policy on all external interfaces for the Xdmcp port if you are doing this on a laptop or a PC in an untrusted environment.

    If you are done, simply launch Xephyr:

    Xephyr -query localhost :1 -host-cursor -screen 1024x768&
    

    where -host-cursor tries to reuse the host's cursor and -screen sets the screen dimensions.

    Note: If you get lots of refused connection errors, you might want to use the -ac option of Xephyr. For example:

    Xephyr -ac :1&
    

    Another option to try if you get lots of refused connection errors is you may need to grant assess to your kde-devel user to your X server. As root or using sudo execute:

    xhost +local:kde-devel
    

    如果没有Xephyr,也可以用Xnest:

    Xnest -ac :1& export DISPLAY=:1
    



    Warning

    cleanup confusing sections and fix sections which contain a todo


    Sping 00:25, 9 April 2007 (CEST)
    I use this for my start script nested_kde4.sh:

    #! /bin/bash
    NESTED_KDE_DISPLAY_BACKUP=$DISPLAY
    export DISPLAY=:0
    Xephyr :1 -screen 1024x768 &
    export DISPLAY=:1
    $HOME/kde/bin/startkde-modified &
    export DISPLAY=${NESTED_KDE_DISPLAY_BACKUP}
    

    如果碰到:

    "Call to lnusertemp failed (temporary directories full?).
     Check your installation."
    

    试试这个:

    mkdir /var/tmp/kde-devel-kde4
    

    The above code assumes you work with user kde-devel.

    Note
    In most cases you have to replace startkde-modified with startkde

    Solitary KDE 4会话

    Solitary

    运行一个完整的KDE 4桌面会话,you can either start it from the command line as you normally would, with something like this:

    X :1 & export DISPLAY=:1
    startkde
    
    Note
    If the X server refuses the connection saying something like: Xlib: connection to ":1.0" refused by server, try X -ac :1 instead.


    or you can can add it to your login manager. If you are using KDM (or a compatible login manager) this is done by creating a .desktop file in either `kde-config --prefix`/share/apps/kdm/sessions/ or in /usr/share/xsessions/. The easiest thing to do is to copy an existing kde.desktop file and name it kde4.desktop. Open this new .desktop file in a text editor and change the Exec, TryExec and Name entries to look something like this:

    Exec=$HOME/kde/bin/startkde
    TryExec=$HOME/kde/bin/startkde
    Name=KDE4
    

    Replace $HOME/kde in the example above with the prefix you are installing KDE4 into.

    After restarting the login manager (Alt+e in KDM) this new entry should appear in the sessions menu.

    Note
    You should have path to 'qdbus' program (usually it is $QTDIR/bin) in your $PATH to login successfully. If it is not there, you'll get an error message "Could not start DBus. Check your installation."


    开发任务

    KDevelop

    这里讲述如何用Kdeveloper 3.4 开发KDE 4 的应用。有问题,建议,纠正的话,请在讨论页面提出。

    前提条件

    You need at least KDevelop 3.4 for this, which is still a KDE 3 application. Versions lower than 3.4 do not have Qt 4 support among other things. The KDE 4 version of KDevelop is not yet ready for serious development. You can get KDevelop at the KDevelop homepage. Make sure you install KDevelop like all other KDE 3 applications, not with your kde-devel user.

    安装最新的GDB,版本是 6.6.0。

    本地安装kdelibs API文档,里面简述了构建指令

    你还需要ctags, htdig, htmergehtsearch. valgrindcallgrind也是有用的。

    确保你遵循KDE 4的构建指令以及一个可用的KDE 4环境。确保一些简单的KDE 4应用如KonsoleKWrite,可以从命令行构建,用kde-devel用户。

    The following steps are all done with the kde-devel user. You need to login as that user by typing

    su - kde-devel
    

    .

    设置环境

    KDevelop并不与生俱来就支持CMake。但,CMake可以产生KDevelop项目文件,只要在执行cmake命令时加上 -GKDevelop3。他会告诉CMake,产生KDevelop项目文件和通用makefiles文件。The best way to do this is to modify your cmakekde function in your .bashrc。改变如下:

    cmake $srcFolder -DCMAKE_INSTALL_PREFIX=$KDEDIR \
    -DCMAKE_BUILD_TYPE=debugfull&& \
    make && \
    make install;
    

    to

    cmake $srcFolder -GKDevelop3 -DCMAKE_INSTALL_PREFIX=$KDEDIR \
    -DCMAKE_BUILD_TYPE=debugfull&& \
    make && \
    make install;
    

    After you have done that, re-login so that the changes to the .bashrc file take effect. Then you need to rerun cmakekde in the (root) build directory of the project you want to work on with KDevelop (if you didn't use -GKDevelop3 on the building step). For example, if you want to work on Konsole, which lives in kdebase, you need to run cmakekde in the $KDE_BUILD/KDE/kdebase directory. This unfortunately completely rebuilds everything, but only once when you change the generator.

    Since all environment variables of the kde-devel user are KDE 4 specific, these need to be set back to match your KDE 3 environment before starting KDevelop. A simple way to do this is to add the following function to your .bashrc:

    function start3app {
      mkdir -p /tmp/$USER-kde
      export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/bin/X11:/usr/games 
      export LD_LIBRARY_PATH= 
      export KDETMP=/tmp/$USER-kde 
      export KDEVARTMP=/var/tmp/$USER-kde 
      export KDEHOME=$HOME/.kde 
      export KDEDIR=/usr 
      export KDEDIRS=$KDEDIR 
      export DISPLAY=:0 
      eval "$@"
      source $HOME/.bashrc   #Reset environment variables again
    }
    

    The PATH and LD_LIBRARY_PATH variables are taken from the KDE 3 user, and they may be different on your system. Type

    echo $PATH
    

    and

    echo $LD_LIBRARY_PATH
    

    as normal KDE 3 user to get these values. The above function assumes that KDE 3 is installed in the /usr prefix, as it is the case on Debian-based systems. If your KDE 3 is installed to a different prefix, for example /opt/kde3, you need to change the line setting KDEDIR accordingly.

    Now you should be able to start KDevelop by typing start3app kdevelop. Do that now.

    Tip
    可以用start3app启动KDE 3应用程序。Useful candidates include Kompare and kdesvn. However, you can not start KDbg this way to debug KDE 4 applications, since then the environment variables for the debugged application are wrong.


    设置KDevelop

    Now that KDevelop has started, you need to adjust a few settings. Go to Settings->Configure KDevelop...->Documentation for this. Remove all entries that are not relevant to KDE 4 coding.

    Note
    Although environment variables like $HOME are used in this section, you should replace them with real paths because KDevelop does not resolve environment variables.


    点击Add...,添加KDELib的API文档。对话框中,用下列设置:

    • Type: Doxygen文档集 (设为首位)
    • Location: $KDE_SRC/KDE/kdelibs/kdelibs-apidocs/index.html

    添加Qt API文档,用下列设置:

    • Type: Qt文档集 (设为首位)
    • Location: $HOME/qt-copy/doc/html/qt.dcf

    After you have added kdelibs and Qt API documentation, make sure all checkboxes (TOC,Index and Search) are enabled. Then, go to the Full Text Search tab and make sure the paths to the htdig, htmerge and htsearch executables are correct. You can then close the settings dialog.

    Now it is time to open the project you want to work on by clicking Project->Open Project.... The project files are located in the directory. For example, if you want to work on Konsole, you need to open $KDE_BUILD/KDE/kdebase/apps/konsole/konsole.kdevelop. You now need to adjust a few project-specific settings in Project->Project Options. You need to do this every time you start to work on a different project.

    Note
    有时候,KDevelop项目文件并不在工作目录。

    This can have several reasons, it depends on how the CMake files are written. Usually, CMake files which have a project(projectname) statement in them should work fine. Once you are familiar enough with CMake, you can try adding the statement.

    A workaround for this is to simply use the KDevelop project file of the parent folder, or even higher. In this case, you need to use the Make Active Directory entry in the context menu of the File Selector sidetab. With this, you can ignore the other unwanted folders when building and installing.


    • C++ Support->Code Completion
    Here you need to add code completion databases for Qt and kdelibs, and more if you like, for example you might need a database for kdepimlibs when working on kdepim.
    For kdelibs, click the Add... button and choose KDevelop Custom Directory PCS Importer, then add your KDE include directory ($HOME/kde/include) to the list and proceed. You can use the file selection dialog and the Add button to add it.
    Now, add the database for Qt 4 by selecting KDevelop Qt4 PCS Importer this time. You need to select the Qt 4 include directory, which is $HOME/qt-copy/include.
    Note
    The Qt4 PCS Importer is only needed if you didn't install Qt4, i.e. you use it directly from the build directory. The drawback of using the Qt4 importer is that it doesn't show progress and the application seems to hang while it imports. The alternative is to use the Custom Directory PCS Importer for this too


    • C++ Support->Qt Options
    勾上Enable Qt options并选Qt4。Set the QMake Binary path to $HOME/qt-copy/bin/qmake. Then choose Qt 4 style as Qt include syntax. Use $HOME/qt-copy/bin/designer as Designer Binary. Make sure to use the Change Plugin Paths dialog to add the plugin directory from KDE so you see the KDE widgets when designer is started. To do this add $HOME/kde/lib/kde4/plugins to the lineedit and then click the Add button.
    • Run Options
    Make sure you use the correct binary as Executable. For example, if you want to run Konsole, this is $KDE_BUILD/KDE/kdebase/apps/konsole/src/konsole. You should add --nofork to the Debug Arguments or debugging some applications like KMail will not work at all.
    Because the start3app functions changes some environment variables, you need to change them back here so the KDE 4 applications can be run without problems from within KDevelop.
    For some applications, like Konsole, this is not strictly necessary, but others like KMail will crash if you do not change this.
    Simply click the Add / Copy button to add new environment variables. You will need the following, which are the same as in your .bashrc:
    Name Value
    KDEHOME $HOME/.kde4
    PATH $QTDIR/bin:$KDEDIR/bin:/usr/local/bin:$PATH
    LD_LIBRARY_PATH $QTDIR/lib:$KDEDIR/lib:$LD_LIBRARY_PATH
    KDETMP /tmp/$USER-kde4
    KDEVARTMP /var/tmp/$USER-kde4
    KDEDIR $HOME/kde
    KDEDIRS $KDEDIR
    LD_BIND_NOW 42


    • Build Options->Build
    Make sure the correct build directory is selected. Again, for Konsole, this would be $KDE_BUILD/KDE/kdebase/apps/konsole.
    • Build Options->Make
    You might want to check Abort on first error. You also might want to add VERBOSE= or VERBOSE=1 to Additional make options to control the level of verbosity for the build process.
    If you have more than one processor or if you have access to an icecream cluster, you might want to check the Run multiple jobs option and set the Number of simultaneous jobs to the number of available processors. This increases the compile speed. It is the same as the -j option for make.
    • 格式(Formatting)
    You should set all options here to match the coding style of the project you are working on.
    • CTags->General
    You need to correctly set the Path to ctags binary, which is /usr/bin/ctags on Debian-based systems.
    You probably want to enable the When more than one hit, go directly to the first option.

    Now you have finished adjusting your project-specific settings. Now you should remove some plugins you do not need, in Settings->Configure Plugins.... I for example disable the following plugins:

    Abbreviation Expansion, Code Snippets, Doxygen Support, Embedded Konsole, File Tree, Final Packaging Support, "Open with" Menu Addon, QuickOpen, Regular Expression Tester, Scripting, Security Checker, Shell Filtering and Insertion, Text Structure and Tools Menu Addition.

    至少把那些粗体的给禁掉。

    Now, open any source file if none is open already. This will enable the Settings->Configure Editor... entry, where you need to set the tab options to match the tab style used by the project you are working on. The important settings are:

    • Appearance->Borders->Show line numbers: 要检查。
    • Appearance->Borders->Show icon border: 要检查。
    • Editing->Tabulators
    • Editing->Static Word Wrap->Show marker: 要检查。
    • Indentation->Automatic Indentation->Indentation mode: 应该是C Style
    • Indentation 整体介绍

    在主窗口, 点击下部的CTags插页, 然后选Regenerate按钮来创建一个CTags数据库;这样可以方便的在代码中穿梭来回。

    至此,所有必要设置都完成了,恭喜,你可以开始工作了!

    使用KDevelop

    参考KDevelop手册,那里有关于KDevelop的整体介绍。下面会介绍些KDE 4的一些特殊事物。

    调试

    KDE有很多符号,这就意味着在调试时,你需要大内存。引用一个GDB开发员的话语: "在低于1GB内存的机器上调试KDE程序是件很讨厌的事情。" 如果调试的确很慢,试试下列技巧:

    • 隐藏本地变量。The Locals part of the variable tab on the left causes a big slowdown when stepping if you have many local variables. Simple collapse the Locals part of the tree, the local variables are then not updated every step. You can still examine variables by using the Evaluate expression function.
    • 用这个补丁:http://bugs.kde.org/show_bug.cgi?id=143977。It prevents the update of the framestack widget at each step, speeding up stepping considerably. The patch introduces some minor glitches, which is why it is not yet commited.
    Note
    KDevelop目前还不支持编辑CMake联编系统。This means you can not use KDevelop to add or remove files from the project or to change any other aspect of your project's build process. 你的手工编辑CMake文件and then rerun cmakekde instead. 请阅读 CMake教程以了解如何实施。


    Tip
    使用类库前,一定要先安装,然后你才能测试和调试。

    这个很麻烦也很耗时间, 你应该对所有可能引用到的类库建立符号链接((ln -s)),把它们从构建目录连到安装目录。

    通常,最简单的程序也会在其中调用一些类库,例如Konsole就是一种类库。

    Eclipse

    KDE4's ktimetracker loaded as eclipse project

    This describes how to use Eclipse to develop KDE 4 applications. It has been tested with Eclipse Ganymed and SUSE Linux 11.1 but should work same or similar with every combination. As an example KDE application we use ktimetracker from the kdepim module, other applications short work analog.

    Using this description you will be able to

    • update your working copy of KDE source code using the command svn
    • build your KDE module using cmake
    • build your KDE application from within eclipse using make
    • compile and run your application with one click from eclipse
    • get auto-completion when editing KDE source code
    • have an overview and navigation about your classes within eclipse
    • have call trees for your functions

    Set up Eclipse with KDE

    • Check your requirements
    Trying with a virtual machine I had problems starting Eclipse with less than 1 GB RAM. After assigning 3 GB RAM to my virtual machine, Eclipse finally started.
    • Install eclipse
    Download Eclipse IDE for C/C++ developers from http://www.eclipse.org. We unpack it to /home/user/eclipse.
    • Install the CDT
    Download the Eclipse IDE for C/C++ Developers (68 MB) from http://www.eclipse.org/cdt/ and unpack it into your eclipse folder, in our case /home/user/eclipse.
    • Download kdepim
    As said, we use kdepim as example here. So, download ("checkout") kdepim using svn, e.g. as anonymous:
    svn co svn://anonsvn.kde.org/home/kde/trunk/KDE/kdepim
    
    We assume you checked out into /home/user/kdepim.
    • Compile kdepim
    Compile kdepim so the usual makefiles are present for all kdepim applications. If you have problems doing this, follow our build instructions
    • Import your project into eclipse
    Surprise: To import your project, you should not use "File -> Import". Rather do: File -> New -> C++ Project -> Makefile project -> Empty Project -> un-tag "use default location" -> choose /home/user/kdepim/ktimetracker. Call it "ktimetracker".
    • Build your project
    Make sure Project -> Properties -> C/C++ Build -> Builder Settings -> Build location -> Build directory is set correctly.
    Choose Project -> Build Project
    • Run the project
    Choose Project -> Properties -> Run/Debug Settings -> New. As project, enter ktimetracker, as C/C++ Application, enter /home/user/kdepim/ktimetracker/ktimetracker. Choose Apply -> Ok -> Ok. Now you can click on the "Run" button and start it.

    Know-How

    Custom builders

    If you want to integrate the cmake build step into your build toolchain, you will need to

    • create a custom builder like this:
    cat >/bin/eclipsebuild<<EOF
    cmake . && make -j4 && make install
    EOF
    chmod 777 /bin/eclipsebuild
    
    • Add your builder
    Choose Project -> Properties -> Builders. Un-tag all existing builders. Click "new" -> Program -> (name it "Builder for KDE"). -> Location: /bin/eclipsebuild -> Working directory /home/user/workspace/myproject1/kdepim.
    • Build
    Now you can build your project. Every time after you restarted eclipse, choose myproject1 -> Project -> Properties -> C/C++ Build -> Ok -> Project -> Build.
    Revert what eclipse did

    To revert what eclipse did to your project simply run

    rm -rf .externalToolBuilders/ .project .cproject
    
    Why Subversion does not work

    When using eclipse's svn plugin and building a KDE program, you will get error messages complaining that your svn binary is too old. If you want to try and change this, here's how you get to that error:

    • Install the subversion plug-ins
