Compiling the GNOME Print library — How to compile libgnomeprint
Building GNOME Print on UNIX-like systems
This chapter covers building and installing GNOME Print on UNIX and UNIX-like systems such as Linux.
Before we get into the details of how to compile GNOME Print, we should mention that in many cases, binary packages of GNOME Print 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 GNOME Print much faster than building it yourself. In fact, you may well already have GNOME Print installed on your system already.
On UNIX-like systems GNOME Print uses the standard GNU build system, using autoconf for package configuration and resolving portability issues, automake for building makefiles that comply with the GNU Coding Standards, and libtool for building shared libraries on multiple platforms.
If you are building GNOME Print 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
tar.gz file which you unpack into a
directory full of the source files as follows:
tar xvfz libgnomeprint-2.0.0.tar.gz
In the toplevel of the directory that is created, there will be
a shell script called
you then run to take the template makefiles called
Makefile.in in the package and create
makefiles customized for your operating system. The
script can be passed various command line arguments to determine how
the package is built and installed. The most commonly useful
argument is the
--prefix argument which
determines where the package is installed. To install a package
/opt/libgnomeprint you would run configure as:
A full list of options can be found by running
configure with the
--help argument. In general, the defaults are
right and should be trusted. After you've run
configure, you then run the
make command to build the package and install
make make install
If you don't have permission to write to the directory you are
installing in, you may have to change to root temporarily before
make install. Also, if you are
installing in a system directory, on some systems (such as
Linux), you will need to run ldconfig after
make install so that the newly installed
libraries will be found.
Several environment variables are useful to pass to set before
CPPFLAGS contains options to
pass to the C compiler, and is used to tell the compiler where
to look for include files. The
is used in a similar fashion for the linker. Finally the
PKG_CONFIG_PATH environment variable contains
a search path that pkg-config (see below)
uses when looking for for file describing how to compile
programs using different libraries. If you were installing GNOME Print
and it's dependencies into
might want to set these variables as:
CPPFLAGS="-I/opt/libgnomeprint/include" LDFLAGS="-L/opt/libgnomeprint/lib" PKG_CONFIG_PATH="/opt/libgnomeprint/lib/pkgconfig" export CPPFLAGS LDFLAGS PKG_CONFIG_PATH
You may also need to set the
environment variable so the systems dynamic linker can find
the newly installed libraries, and the
environment program so that utility binaries installed by
the various libraries will be found.
LD_LIBRARY_PATH="/opt/libgnomeprint/lib" PATH="/opt/libgnomeprint/bin:$PATH" export LD_LIBRARY_PATH PATH
Before you can compile the GNOME Print, 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 GNOME Print mentioned above such as autoconf) are pkg-config and GNU make.
pkg-config is a tool for tracking the compilation flags needed for libraries that is used by the GNOME Print library. (A small
.pctext file is installed in a standard location that contains the compilation flags needed for the library along with version number information.)
The GNOME Print makefiles will mostly work with different versions of make, however, there tends to be a few incompatibilities, so the GNOME Print team recommends installing GNU make if you don't already have it on your system and using it. (It may be called gmake rather than make.)
The libart module. It is available from the GNOME FTP site.
The libxml2 module. It is available from the GNOME FTP site.
The libbonobo module. It's available from the GNOME FTP site.
The GLib library provides core non-graphical functionality such as high level data types, Unicode manipulation, and a object and type system to C programs. It is available from the GTK+ FTP site.
Pango is a library for internationalized text handling. It is available from the GTK+ FTP site.
The libintl library from the GNU gettext package is needed if your system doesn't have the
gettext()functionality for handling message translation databases.
Building and testing GNOME Print
First make sure that you have the necessary dependencies installed: pkg-config, GNU make, libart, libxml2, libbonobo, glib, and, if necessary, 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 pkg-config.
Then build and install the GNOME Print library, follow the
make install mentioned above. If you're
lucky, this will all go smoothly, and you'll be ready to
start compiling your own
GNOME Print applications.
configure scripts fails or running
make fails, look closely at the error
messages printed; these will often provide useful information
as to what went wrong. When
fails, extra information, such as errors that a test compilation
ran into, is found in the file
Looking at the last couple of hundred lines in this file will
frequently make clear what went wrong. If all else fails, you
can ask for help on the gnome-print mailing list.
See Mailing lists and bug reports(3) for more information.
Extra Configuration Options
In addition to the normal options, the configure script for the GNOME Print library supports a number of additional arguments.
configure [[--with-omni-libdir=DIR]] [[--with-omni-includedir=DIR]] [[--enable-font-install=[yes|no]]] [[--with-html-dir=PATH]] [[--disable-gtk-doc] | [--enable-gtk-doc]]

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