<title>Building GTK+ on UNIX-like systems</title>
|
|
<para>
|
|
This chapter covers building and installing GTK+ on UNIX and
|
|
UNIX-like systems such as Linux. Compiling GTK+ on Microsoft
|
|
Windows is different in detail and somewhat more difficult to
|
|
get going since the necessary tools aren't included with
|
|
the operating system.
|
|
</para>
|
|
<para>
|
|
Before we get into the details of how to compile GTK+, we should
|
|
mention that in many cases, binary packages of GTK+ prebuilt for
|
|
your operating system will be available, either from your
|
|
operating system vendor or from independent sources. If such a
|
|
set of packages is available, installing it will get you
|
|
programming wih GTK+ much faster than building it yourself. In
|
|
fact, you may well already have GTK+ installed on your system
|
|
already.
|
|
</para>
|
|
<para>
|
|
On UNIX-like systems GTK+ uses the standard GNU build system,
|
|
using <application>autoconf</application> for package
|
|
configuration and resolving portability issues,
|
|
<application>automake</application> for building makefiles that
|
|
comply with the GNU Coding Standards, and
|
|
<application>libtool</application> for building shared libraries
|
|
on multiple platforms.
|
|
</para>
|
|
<para>
|
|
If you are building GTK+ from the distributed source packages,
|
|
then won't need these tools installed; the necessary pieces
|
|
of the tools are already included in the source packages. But
|
|
it's useful to know a bit about how packages that use these
|
|
tools work. A source package is distributed as a
|
|
<literal>tar.gz</literal> or <literal>tar.bz2</literal> file
|
|
which you unpack into a directory full of the source files as follows:
|
|
</para>
|
|
<programlisting>
|
|
tar xvfz gtk+-3.0.0.tar.gz
|
|
tar xvfj gtk+-3.0.0.tar.bz2
|
|
</programlisting>
|
|
<para>
|
|
In the toplevel of the directory that is created, there will be
|
|
a shell script called <filename>configure</filename> which
|
|
you then run to take the template makefiles called
|
|
<filename>Makefile.in</filename> in the package and create
|
|
makefiles customized for your operating system. The <filename>configure</filename>
|
|
script can be passed various command line arguments to determine how
|
|
the package is built and installed. The most commonly useful
|
|
argument is the <systemitem>--prefix</systemitem> argument which
|
|
determines where the package is installed. To install a package
|
|
in <filename>/opt/gtk</filename> you would run configure as:
|
|
</para>
|
|
<programlisting>
|
|
./configure --prefix=/opt/gtk
|
|
</programlisting>
|
|
<para>
|
|
A full list of options can be found by running
|
|
<filename>configure</filename> with the
|
|
<systemitem>--help</systemitem> argument. In general, the defaults are
|
|
right and should be trusted. After you've run
|
|
<filename>configure</filename>, you then run the
|
|
<command>make</command> command to build the package and install
|
|
it.
|
|
</para>
|
|
<programlisting>
|
|
make
|
|
make install
|
|
</programlisting>
|
|
<para>
|
|
If you don't have permission to write to the directory you are
|
|
installing in, you may have to change to root temporarily before
|
|
running <literal>make install</literal>. Also, if you are
|
|
installing in a system directory, on some systems (such as
|
|
Linux), you will need to run <command>ldconfig</command> after
|
|
<literal>make install</literal> so that the newly installed
|
|
libraries will be found.
|
|
</para>
|
|
<para>
|
|
Several environment variables are useful to pass to set before
|
|
running configure. <envar>CPPFLAGS</envar> contains options to
|
|
pass to the C compiler, and is used to tell the compiler where
|
|
to look for include files. The <envar>LDFLAGS</envar> variable
|
|
is used in a similar fashion for the linker. Finally the
|
|
<envar>PKG_CONFIG_PATH</envar> environment variable contains
|
|
a search path that <command>pkg-config</command> (see below)
|
|
uses when looking for for file describing how to compile
|
|
programs using different libraries. If you were installing GTK+
|
|
and it's dependencies into <filename>/opt/gtk</filename>, you
|
|
might want to set these variables as:
|
|
</para>
|
|
<programlisting>
|
|
CPPFLAGS="-I/opt/gtk/include"
|
|
LDFLAGS="-L/opt/gtk/lib"
|
|
PKG_CONFIG_PATH="/opt/gtk/lib/pkgconfig"
|
|
export CPPFLAGS LDFLAGS PKG_CONFIG_PATH
|
|
</programlisting>
|
|
<para>
|
|
You may also need to set the <envar>LD_LIBRARY_PATH</envar>
|
|
environment variable so the systems dynamic linker can find
|
|
the newly installed libraries, and the <envar>PATH</envar>
|
|
environment program so that utility binaries installed by
|
|
the various libraries will be found.
|
|
</para>
|
|
<programlisting>
|
|
LD_LIBRARY_PATH="/opt/gtk/lib"
|
|
PATH="/opt/gtk/bin:$PATH"
|
|
export LD_LIBRARY_PATH PATH

Before you can compile the GTK+ widget toolkit, you need to have
|
|
various other tools and libraries installed on your
|
|
system. The two tools needed during the build process (as
|
|
differentiated from the tools used in when creating GTK+
|
|
mentioned above such as <application>autoconf</application>)
|
|
are <command>pkg-config</command> and GNU make.

First make sure that you have the necessary external
|
|
dependencies installed: <command>pkg-config</command>, GNU make,
|
|
the JPEG, PNG, and TIFF libraries, FreeType, and, if necessary,
|
|
libiconv and libintl. To get detailed information about building
|
|
these packages, see the documentation provided with the
|
|
individual packages.
|

On a Linux system, it's quite likely you'll have all of these
|
|
installed already except for <command>pkg-config</command>.
|
|
</para>
|
|
<para>
|

Then build and install the GTK+ libraries in the order:

GLib, Pango, ATK, then GTK+. For each library, follow the

steps of <literal>configure</literal>, <literal>make</literal>,
|
|
<literal>make install</literal> mentioned above. If you're

lucky, this will all go smoothly, and you'll be ready to

Normally GTK+ will try to build the input method modules

as little shared libraries that are loaded on

demand. The <systemitem>--disable-modules</systemitem>
|

argument indicates that they should all be built statically
|
|
into the GTK+ library instead. This is useful for

people who need to produce statically-linked binaries. If

neither <systemitem>--disable-modules</systemitem> nor

<systemitem>--enable-modules</systemitem> is specified, then

the <command>configure</command> script will try to

Turns on various amounts of debugging support. Setting this to 'no'

disables g_assert(), g_return_if_fail(), g_return_val_if_fail() and

If <systemitem>--enable-explicit-deps</systemitem> is

specified then GTK+ will write the full set of libraries

that GTK+ depends upon into its <literal>.pc</literal> files to be used when
|
|
programs depending on GTK+ are linked. Otherwise, GTK+
|
|
only will include the GTK+ libraries themselves, and
|
|
will depend on system library dependency facilities to
|
|
bring in the other libraries.
|
|
By default GTK+ will disable explicit dependencies unless
|
|
it detects that they are needed on the system. (If you
|
|
specify <systemitem>--enable-static</systemitem> to force
|
|
building of static libraries, then explicit dependencies
|
|
will be written since library dependencies don't work
|
|
for static libraries.) Specifying
|
|
<systemitem>--enable-explicit-deps</systemitem> or
|
|
<systemitem>--enable-static</systemitem> can cause
|
|
compatibility
|
|
problems when libraries that GTK+ depends upon change

their versions, and should be avoided if possible.

<para>
|

The <application>gtk-doc</application> package is
|
|
used to generate the reference documentation included
|
|
with GTK+. By default support for <application>gtk-doc</application>
|
|
is disabled because it requires various extra dependencies
|
|
to be installed. If you have
|
|
<application>gtk-doc</application> installed and
|
|
are modifying GTK+, you may want to enable
|
|
<application>gtk-doc</application> support by passing
|
|
in <systemitem>--enable-gtk-doc</systemitem>. If not
|
|
enabled, pre-generated HTML files distributed with GTK+
|
|
will be installed.

By default the <command>configure</command> script will try

These options can be used to explicitly control whether

the cups print backend should be built.

<para>
|

Controls whether GTK+ is built with support for the XInput
|
|
or XInput2 extension. These extensions provide an extended
|
|
interface to input devices such as graphics tablets.
|
|
When this support is compiled in, specially written
|
|
GTK+ programs can get access to subpixel positions,
|
|
multiple simultaneous input devices, and extra "axes"
|
|
provided by the device such as pressure and tilt
|
|
information.

Toggles between the supported backends for GDK.

The default is x11, unless the platform is Windows, in which

|
case the default is win32. Other supported backends are
|
|
the quartz backend for OS X.
