KDevelop/HowToCompile v4

The way to download, compile, install and run KDevelop depends on how you want to download it and where do you want to install it to. So follow the step by step instructions below.

1. Get the requirements

Make sure to install the required KDE development packages, see KDevelop4/requirements for a list of requirements. In particular make sure to install KDE4 kdelibs development packages. At least following packages are required:

In Fedora 13: kdelibs-devel kdebase-workspace-devel

In Ubuntu 11.04: cmake gcc g++ kdelibs5-dev zlib1g-dev kdebase-workspace-dev

WARNING: You have to remove all KDevelop packages provided by your distribution. If you don't do that, binary compatibility issues will eventually lead to crashes and undefined behavior. To make sure, you can search for KDevelop libraries with this command:

find /usr/ -type f -name "*kdev*.so*"

If no results are returned, you should be on the safe side.

2. Get the sources (assumes $HOME/src but you can replace it with something else)

• By downloading it to $HOME/src
  • download kdevplatform.tar.bz2 and kdevelop.tar.bz2 from http://download.kde.org/download.php?url=stable/kdevelop/4.1.2/src/
  • unpack them:

             cd $HOME/src
             tar xvjf kdevplatform.tar.bz2
             tar xvjf kdevelop.tar.bz2

• Or, by getting the latest master branch sources directly out of the Git server

       git clone git://anongit.kde.org/kdevplatform $HOME/src/kdevplatform
       git clone git://anongit.kde.org/kdevelop $HOME/src/kdevelop

Please note that this branch will depend on MovingRange in Kate, meaning KDE 4.5 and above. This can be updated by doing sudo yum update kdelibs or equivalent.

• Or, by getting the latest 4.2-branch sources directly out of the Git server. First you need to do clone git reposity as above, and then tell git to use branch 1.1 for kdevplatform and branch 4.1 for kdevelop:

       cd  $HOME/src/kdevplatform ; git checkout -b 1.2 origin/1.2
       cd  $HOME/src/kdevelop ; git checkout -b 4.2 origin/4.2

3. Configure and install

You can do a system install of KDevelop in the default path (/usr/local), which needs root privileges, or you can install it locally for your user only. The instructions for both are slightly different; first we'll explain the local install.

In both cases you need set the KDEDIRS environment variable to point to the installation directory of both KDE4 and KDevPlatform.

This will tell KDE core components where to search for plugins and other data related to KDE apps and contains just a list of paths (aka prefixes) where KDE libraries and/or applications have been installed.

Assuming that you have the KDE4 libraries installed in /usr (these are often from packages and installed in /usr or /opt/kde and is distro specific, if unsure ask your distro where it is), you'll have to append it to the KDEDIRS below.

Local installation

The following commands give instructions to install in $HOME/kdevelop4; you can of course replace it with something else. You don't need root permissions to install KDevelop this way.

First, compile and install KDevPlatform:

   mkdir -p $HOME/src/kdevplatform/build
   cd $HOME/src/kdevplatform/build
   cmake -DCMAKE_INSTALL_PREFIX=$HOME/kdevelop4 ../
   make
   make install

Then compile KDevelop, telling it to use the just-installed KDevPlatform:

   mkdir -p $HOME/src/kdevelop/build
   cd $HOME/src/kdevelop/build
   cmake -DCMAKE_PREFIX_PATH=$HOME/kdevelop4 -DCMAKE_INSTALL_PREFIX=$HOME/kdevelop4 ../
   make
   make install

Before running KDevelop, you need set the KDEDIRS environment variable. Assuming that you want to install KDevelop4 into $HOME/kdevelop4 then you need to run the following:

   export KDEDIRS=$HOME/kdevelop4:/$KDEDIRS
   kbuildsycoca4

Note that this will set the KDEDIRS variable only for that shell (so launching kdevelop from desktop launcher will fail). A good solution is to add to a small script to $HOME/.kde/env that sets the KDEDIRS variable to proper. For example you may call it $HOME/.kde/env/kdedirs.sh and it could contain:

   #!/bin/bash
   export KDEDIRS=/usr/local/:$KDEDIRS

And it needs to have execution permissions.

System installation

First, compile and install KDevPlatform:

   mkdir -p $HOME/src/kdevplatform/build
   cd $HOME/src/kdevplatform/build
   cmake ../
   make
   sudo make install

Then compile KDevelop:

   mkdir -p $HOME/src/kdevelop/build
   cd $HOME/src/kdevelop/build
   cmake ../
   make
   sudo make install

Before running it, you need to set KDEDIRS properly as in local installation but with path as /usr/local/.

4. Get and install plugins (optional)

If you need extra functionality, you can get and install additional plugins for KDevelop4 at KDevelop 4/compiling/plugins.

5. Run KDevelop

Just execute:

       $HOME/kdevelop4/bin/kdevelop

(If you want to ease it, you can add $HOME/kdevelop4/bin/ to your $PATH env variable).

6. Contact the development team, or report bugs or wishes

If you find any compile problems with KDevelop4 please report them on our developer mailing-list. If you find problems while using KDevelop4 use, the bugzilla bug database which is only for bugs (not for compilation issues).

If you find bugs that cause program to crash and you are going to make bug report out of it, please re-compile the program with debug symbols. This is done with options

-DCMAKE_BUILD_TYPE=debugfull

passed to cmake in configuration step. Also be sure to update kdevelop and kdevplatform to newest version, your bug might be already fixed.

7. Keeping it up-to-date with the latest fixes

If you got the sources from the git repository on step 2. then you can update by issuing the following commands:

• with root permissions do this

       cd $HOME/src/kdevelop/build && sudo make uninstall
       cd $HOME/src/kdevplatform/build && sudo make uninstall
       git pull && make && sudo make install
       cd $HOME/src/kdevelop/build
       git pull && make && sudo make install
       kbuildsycoca4

• Or if installed in local directory

       cd $HOME/src/kdevelop/build && make uninstall
       cd $HOME/src/kdevplatform/build && make uninstall
       git pull && make && make install
       cd $HOME/src/kdevelop/build
       git pull && make && make install
       kbuildsycoca4
