<title>How do I configure/compile GTK+?</title>
<para>Generally, all you will need to do is issue the commands:</para>
<para><literallayout><literal>./configure</literal>
<literal>make</literal></literallayout></para>
<para>in the gtk+-version/ directory.</para>
</sect2>
<!-- ----------------------------------------------------------------- -->
<sect2>
<title>When compiling GTK+ I get an error like: <literal>make:
file `Makefile' line 456: Syntax error</literal></title>
<para>Make sure that you are using GNU make (use <literal>make
-v</literal>
to check). There are many weird and wonderful versions of make
out there, and not all of them handle the automatically
generated Makefiles.</para>
</sect2>

<sect2>
<title>I've compiled and installed GTK+, but I can't get any
programs to link with it!</title>
<para>This problem is most often encountered when the GTK+
libraries can't be found or are the wrong version. Generally,
the compiler will complain about an 'unresolved symbol'.
There are two things you need to check:</para>
<itemizedlist>
<listitem><simpara>Make sure that the libraries can be
found. You want to edit <filename>/etc/ld.so.conf</filename> to
include the directories which contain the GTK libraries,
so it looks something like:</simpara>
<para><literallayout><literal>/usr/X11R6/lib</literal>
<literal>/usr/local/lib</literal></literallayout></para>
<para>Then you need to run /sbin/ldconfig as root. You can
find what directory GTK is in using</para>
<para><literallayout><literal>gtk-config --libs</literal>
</literallayout></para>
<para>If your system doesn't use ld.so to find libraries
(such as Solaris), then you will have to use the LD_LIBRARY_PATH
environment variable (or compile the path into your program, which I'm
not going to cover here). So, with a Bourne type shell you can do (if
your GTK libraries are in /usr/local/lib):</para>
<para><literallayout><literal>export LD_LIBRARY_PATH=/usr/local/lib</literal></literallayout></para>
<para>and in a csh, you can do:</para>
<para><literallayout><literal>setenv LD_LIBRARY_PATH /usr/local/lib</literal></literallayout></para>
</listitem>
<listitem><simpara>Make sure the linker is finding the
correct set of libraries. If you have a Linux distribution that
installs GTK+ (e.g. RedHat 5.0) then this older version may be
used. Now (assuming you have a RedHat system), issue the
command</simpara>
<para><literallayout><literal>rpm -e gtk gtk-devel</literal></literallayout></para>
<para>You may also want to remove the packages that depend
on gtk (rpm will tell you which ones they are). If you don't have a RedHat Linux system, check to make sure
that neither <filename>/usr/lib</filename> or <filename>/usr/local/lib</filename> contain any of
the libraries libgtk, libgdk, libglib, or libgck. If they do exist, remove them
(and any gtk include files, such as <filename>/usr/include/gtk</filename> and <filename>/usr/include/gdk</filename>)
and reinstall gtk+.</para>
</listitem>
</itemizedlist>

<!-- ----------------------------------------------------------------- -->
<sect2>
<title>When compiling programs with GTK+, I get compiler error
messages about not being able to find
<literal>glibconfig.h</literal>.</title>
<para>The header file "glibconfig.h" was moved to the
directory $exec_prefix/lib/glib/include/. $exec_prefix is the
directory that was specified by giving the --exec-prefix flags
to ./configure when compiling GTK+. It defaults to $prefix,
(specified with --prefix), which in turn defaults to /usr/local/.</para>
<para>This was done because "glibconfig.h" includes
architecture dependent information, and the rest of the
include files are put in $prefix/include, which can be shared
between different architectures.</para>
<para>GTK+ includes a shell script, <literal>/gtk-config/</literal>, that makes it
easy to find out the correct include paths. The GTK+ Tutorial
includes an example of using <literal>/gtk-config/</literal> for simple
compilation from the command line. For information about more
complicated configuration, see the file docs/gtk-config.txt in
the GTK+ distribution.</para>
<para>If you are trying to compile an old program, you may be
able to work around the problem by configuring it with a
command line like:</para>
<para><literallayout><literal>setenv CPPFLAGS "-I/usr/local/include/glib/include"</literal>
<literal>./configure</literal></literallayout></para>
<para>(Substitute the appropriate value of $exec_prefix for
/usr/local.)</para>

<sect2>
<title>When installing a GTK+ application, configure reports
that it can't find GTK.</title>
<para>There are several common reasons for this:</para>
<itemizedlist>
<listitem><simpara>You have an old version of GTK installed
somewhere. RedHat 5.0, for example, installs an older copy of GTK that
may not work with the latest applications. You should remove this old
copy, but note that in the case of RedHat 5.0 this will
break the <literal>control-panel</literal> applications.</simpara>
</listitem>
<listitem><simpara><literal>gtk-config</literal> (or another
component of GTK) isn't in your path, or there is an old
version on your system. Type:</simpara>
<para><literallayout><literal>gtk-config --version</literal></literallayout></para>
<para>to check for both of these. If it returns a value
different from what you expect, then you have an old
version of GTK on your system.</para>
</listitem>
<listitem><simpara>The ./configure script can't find the GTK
libraries. As ./configure compiles various test programs, it needs to
be able to find the GTK libraries. See the question above
for help on this. </simpara></listitem>
</itemizedlist>
<para>If none of the above help, then have a look in
config.log, which is generated by ./configure as it runs. At the
bottom will be the last action it took before failing. If it is a
section of source code, copy the source code to a file and compile it
with the line just above it in config.log. If the compilation is
successful, try executing it.</para>
