&kdevelop; is available in binary form from many different &Linux; distributions such as <!--&SuSE;, &RedHat;//--> SuSE, RedHat and others. These binaries are packed in some convenient format, mostly RPM, for easy installation. To install, follow the standard instructions given in your distribution.
48
You may as well obtain the &kdevelop; sources, compile and install them by yourself. These sources can be found via the project home page at <ulink url="http://www.kdevelop.org"> http://www.kdevelop.org</ulink> or via the <ulink url="http://download.kde.org">&kde; ftp site</ulink>.

72
To obtain an initial version of &kdevelop; you must download it from anonymous svn. For this so-called <emphasis>checkout</emphasis> operation follow these steps.
76
We assume you want to put your &kdevelop; copy into the <filename class="directory">kde3src</filename> subdirectory of your home directory (<filename class="directory">~</filename>).
79
<informalexample><simplelist>
81
# Create the destination directory, if necessary:
84
<prompt>~> </prompt>
85
<userinput>mkdir kde3src</userinput>
88
<prompt>~> </prompt>
89
<userinput>cd kde3src</userinput>
92
<prompt>~/kde3src> </prompt>
93
<userinput>svn co svn://anonsvn.kde.org/home/kde/branches/KDE/3.5/kdevelop</userinput>
96
<prompt>~/kde3src> </prompt>
97
<userinput>cd kdevelop</userinput>
99
</simplelist></informalexample>
102
Once you have successfully checked out your &kdevelop; version, you may keep up with the changes using the update procedure shown in the next section.
106
Keep the server load low. <emphasis>Please do not checkout every time you want to keep your &kdevelop; up to date!</emphasis> Use svn update for this purpose.
110
Now you may compile your &kdevelop; version as shown in the <link linkend="compile-and-install">&kdevelop; Compilation and Installation</link> section.

126
After you checked out (and successfully compiled) &kdevelop; from svn as shown above, you'll want to keep it up to date in order to get all the patches. Follow these steps. (We again assume you have put your &kdevelop; copy into the <filename class="directory">kde3src</filename> directory.)
129
Note the <command>up</command> (= <emphasis>update</emphasis>) command instead of the <command>co</command> (which stands for <emphasis>checkout</emphasis>).
132
<informalexample><simplelist>

<userinput>cd kde3src</userinput>

145
</simplelist></informalexample>
148
Keep an eye on the messages svn produces during the update sequence. The exact steps in the compilation sequence depend on this.
152
Now you can compile a new &kdevelop; version as shown in the <link linkend="compile-and-install-make-svn">Special svn compilation considerations</link> chapter.

You can, to a certain extent, circumvent the need for &autoconf; ≥ 2.52 and &automake; ≥ 1.6. Just remove the <filename class="directory">admin</filename> directory in your &kdevelop; installation directory and type

at the console. This causes &kdevelop; to use the standard settings in the &kde; <filename class="directory">admin</filename> directory instead.
330
Be careful <emphasis>not to mix &Qt; versions</emphasis>. Always link &kdevelop; to the same &Qt; version your &kde; library was compiled. Otherwise you will most likely experience <emphasis>very strange</emphasis> behaviours.

Before entering the compile sequence you must make sure all libraries and tools are available to the make system. To accomplish this some environment variables need to be properly set. The actual steps to be performed depend on the console shell you use.
387
To avoid typing in all the statements that set the necessary environment variables every time you want to compile, you should put them into your <filename>.bashrc</filename> or <filename>.cshrc</filename> file. This way the environment variables will be properly set every time you start the shell.

In the following discussion we assume that you have put your &kdevelop; sources in the <filename class="directory">~/kde3src/kdevelop</filename> directory.

<sect3 id="compile-and-install-make-svn">

<title>Special svn Compilation Considerations</title>

In case you use a &kdevelop; snapshot from svn the initial compilation steps depend on whether you just did a complete checkout or only updated the source.
451
<term id="compile-and-install-make-svn-co">After a svn Checkout</term>
454
You must <emphasis>initialize the make system</emphasis> after a fresh checkout. The same is true every time you need to start over from scratch. Type:
457
<informalexample><simplelist><member>
458
<prompt>~/kde3src/kdevelop> </prompt>
459
<userinput>make -f admin/Makefile.common svn-clean</userinput>
460
</member></simplelist></informalexample>
462
and then <emphasis>all of the following steps</emphasis>.
465
You might need access to the svn repository for the clean-up if any corrupted or missing files must be reconstructed.
468
The <command>svn-clean</command> command will <emphasis>remove every file</emphasis> not in svn from the directory! Make sure to back up any valuable information before you issue this clean-up command.
474
<term id="compile-and-install-make-svn-up">After a svn Update</term>
477
The next step depends on the output of the svn update sequence. If you got something like (there may be a U or a P marker in the leftmost column, both denoting the file has been changed):
481
U /some_directory_path/Makefile.am
484
or if you just did a full checkout, you must enter:
486
<informalexample><simplelist><member>
487
<prompt>~/kde3src/kdevelop> </prompt>
488
<userinput>make -f Makefile.svn</userinput>

498
<sect3 id="compile-and-install-make-basic">
499
<title>Basic <command>make</command> Command Sequence</title>
502
Once the basic make system is set up you must decide which type of the &kdevelop; system you want to use. This is done in the following configure step which builds the actual <filename>Makefile</filename>s the <command>make</command> command will use.
506
You may drop the <option>--prefix</option> option in the following <command>configure</command> command lines if you want &kdevelop; be installed in the default &kde; directory. See the <link linkend="compile-and-install-options">Some notes on configure options</link> chapter for this.
511
<term>A Debug-Compiled Version</term>
514
If you want to keep track of what your &kdevelop; application does at run-time you may build a debug-compiled version. Just command <command>configure</command> to do so:
517
<informalexample><simplelist><member>
518
<prompt>~/kde3src/kdevelop> </prompt>
519
<userinput>./configure --enable-debug=full --prefix=</userinput>(where-your-kde3-is)
520
</member></simplelist></informalexample>
525
<term>A Release-Compiled Version</term>
527
<para>If you only want to use &kdevelop; as-is a (smaller and faster

531
<informalexample><simplelist><member>

<prompt>~/kde3src/kdevelop> </prompt>
533
<userinput>./configure --prefix=</userinput>(where-your-kde3-is)
534
</member></simplelist></informalexample>
538
If you want to build your own <link linkend="make-api">API documentation</link> for &kdevelop; you must include yet another option in the <command>configure</command> command:
540
<informalexample><simplelist>
541
<member><prompt>~/kde3src/kdevelop> </prompt>
542
<userinput>./configure --</userinput>(options-as-above) <userinput>\</userinput></member> <member><userinput>--with-kdelibsdoxy-dir=$KDEDIR/share/doc/HTML/en/kdelibs-apidocs</userinput></member>
543
</simplelist></informalexample>
549
<term>Make and Install &kdevelop;</term>
552
<command>configure</command> will check the system and build some <filename>Makefile</filename>s according to what it found. The <command>make</command> command will use the main <filename>Makefile</filename> by default. Thus
555
<informalexample><simplelist><member>
556
<prompt>~/kde3src/kdevelop> </prompt>
557
<userinput>make</userinput>
558
</member></simplelist></informalexample>
560
suffices. If necessary, now gain root user rights using the command
562
<informalexample><simplelist><member>
563
<prompt>~/kde3src/kdevelop> </prompt>
564
<userinput>su</userinput>
565
</member></simplelist></informalexample>
567
and entering the root password. Then install the application:
569
<informalexample><simplelist><member>
570
<prompt>~/kde3src/kdevelop> </prompt>
571
<userinput>make install</userinput>
572
</member></simplelist></informalexample>
574
That's all. If you installed &kdevelop; in the default &kde; directory you may now run the IDE. Otherwise some additional steps will be necessary as shown in the <link linkend="compile-and-install-options-dir">Non-default installation directory</link> section below.
579
In fact there usually will have been three &kdevelop;-based applications installed:
582
<listitem><para>The &kdevelop; IDE — this is the place where you will usually work.</para></listitem>
583
<listitem><para>The stand-alone &kdevelop; Assistant documentation browser — isolates all the powerful documentation facilities of the &kdevelop; IDE in a separate tool. This comes in handy when you want to look up some programming documentation but do not want to start the full IDE.</para></listitem>

614
By default <command>configure</command> prepares the IDE to be installed in the default &kde; directory. This is necessary because &kdevelop; assumes direct access to some tools and parts which reside there. If want to use your own installation directory, you must tell <command>configure</command> this by the <option>--prefix</option> option:
616
<informalexample><simplelist><member>
617
<prompt>~/kde3src/kdevelop> </prompt>
618
<userinput>./configure --prefix=</userinput>(where-your-kde3-is)
619
</member></simplelist></informalexample>
621
There is a caveat if you do so. You must provide a means for &kdevelop; to access the needed tools and parts in the &kde; directory when running. (You can still use the IDE without doing so, but with very restrained capabilities.)
624
Call up a shell and have the following commands executed before you start &kdevelop; at the shell prompt.
628
<emphasis>Take care to use the plural:</emphasis> It is <quote><envar>KDEDIRS</envar></quote>, not just <quote><envar>KDEDIR</envar></quote>)
631
<informalexample><simplelist>

<member>The <envar>KDEDIRS</envar> environment variable must be set to the <emphasis>list of active &kde; directories</emphasis> in your system. We use</member>
651
<member><filename class="directory">/usr/local/kde</filename>:<filename class="directory">/opt/kde3</filename></member>

<member>as an example only.</member>
653
<member>The <filename class="directory">/usr/local/kde</filename> directory may for instance contain an incomplete &kde; version you compiled for debug purposes, and the <filename class="directory">/opt/kde3</filename> directory may in addition contain the standard &kde; version from your distribution that is used for everyday work.</member>
657
In a tcsh shell you must set the environment variables using:
659
<informalexample><simplelist><member>
660
<prompt>~> </prompt>
661
<userinput>setenv KDEDIRS /usr/local/kde:/opt/kde3</userinput>

664
The <command>kbuildsycoca</command> command (<quote>build system control cache</quote>) looks around for libraries and caches their location and version, so that &kdevelop; can find them. The caveat is that it takes noticeable time—and it has to be run any time you call up the shell to start &kdevelop; from a non-default directory. You may want to put the above commands into a shell script to reduce the typing effort.
667
(You could as well put the lines in your <filename>.bashrc</filename> or <filename>.cshrc</filename> file, but this is not advisable as <command>kbuildsycoca</command> will then be run any time you call up the shell.)
671
The <command>kbuildsycoca</command> command does not run from within the root. You must call it from a non-root user. (But is <emphasis>not a very good idea</emphasis> after all to do software development from within the root!)

API is the short form of <quote>Application Program Interface</quote>. Actually such an API cotains a series of descriptions (&ie; calling conventions) by which an application program can access the operating system and other services. In our context, however, a broader definition was adopted. The API of a &kde; or &Qt; application is an abstract of the classes and methods interfaces, a synopsis to be used like a dictionary to navigate the sources.
702
There is a version of the most current API available at the <ulink url="http://www.kdevelop.org/HEAD/doc/api/html/index.html">KDevelop-Home website</ulink>. It will be automatically updated every 24 hours so you can keep up.
705
Alas, this version is best used read-only over the internet. If you do not always have internet access you may as well build your own API documentation from the &kdevelop; sources. To do so, you must tell the automake system where to find the KDELIBS API in your system. This is accomplished by the special option <option>--with-kdelibsdoxy-dir</option> in the <command>configure</command> command when you prepare to compile the &kdevelop; sources:
708
<informalexample><simplelist>
710
<prompt>~/kde3src/kdevelop> </prompt>
711
<userinput>./configure --</userinput>(options-as-usual)<userinput> \</userinput>
714
<userinput>--with-kdelibsdoxy-dir=$KDEDIR/share/doc/HTML/en/kdelibs-apidocs</userinput>
716
</simplelist></informalexample>
719
(<command>make</command> will replace the global <varname>$KDEDIR</varname> variable with the actual &kde; directory setting recorded therein.) Then issue a <command>make</command> command <link linkend="compile-and-install-make-basic">as usual</link>. After the &kdevelop; IDE has been built you have the option to build the API as well. For this you must issue
721
<informalexample><simplelist><member>
722
<prompt>~/kde3src/kdevelop> </prompt>
723
<userinput>make apidocs</userinput>
724
</member></simplelist></informalexample>
727
This will build a <filename>Doxyfile</filename> in your &kdevelop; base directory which in turn will be processed by the <application>Doxygen</application> application to build quite a lot of <filename>.html</filename> API files. When this rather lengthy API building process (may last more than an hour on a slow system) finally comes to an end, you must install the API just like you have to install the &kdevelop; IDE itself. If necessary obtain superuser rights by
730
<informalexample><simplelist><member>
731
<prompt>~/kde3src/kdevelop> </prompt>
732
<userinput>su</userinput>
733
</member></simplelist></informalexample>
736
and entering the root password. Then install the API files:
739
<informalexample><simplelist><member>
740
<prompt>~/kde3src/kdevelop> </prompt>
741
<userinput>make install-apidox</userinput>
742
</member></simplelist></informalexample>
745
Once this is done, <command>make</command> will inform you about the directory where you can finally look at the API documentation's contents. Note this address, you can use it from &konqueror; as well as from inside &kdevelop;, in case you have set up the &kdevelop; sources themselves as a project to work on.
749
You will most probably see a lot of warning and/or error messages during the API build run by <application>Doxygen</application>. It is best to ignore them, they are of interest to the &kdevelop; developers only. If the API generation ever comes to a successful end, the <filename>.html</filename> API files will be usable.
