Building SVN versions with CMake

After many years of using the autotools build system, the developers of Scribus have selected CMake as a replacement system. It provides a much more flexible setup with a lot less complexity. It also provides compatibility with build tools on Linux and variants of Unix, Windows and Mac OSX.

'''You must have CMake 2.4.3 for best results. Older versions will fail.'''

First thing first: Download latest snapshot with Subversion
Subversion is the versioning control system used for Scribus. Check this link for instructions for using Subversion.

All subversion URLs for Scribus anonsvn are based at:

svn://scribus.info/Scribus/

There's also http://scribus.info/svn/Scribus/, which gets you to the same content, but svn://scribus.info/Scribus/ is usually faster. HTTP access might be useful to those behind paranoid firewalls or proxies, though.

If you used to check out -r , check out  instead:

So, if I wanted to use svn:// to check out 1.3.3.10svn, I'd run:

svn co svn://scribus.info/Scribus/branches/Version133x/Scribus scribus133x

Updating your working copy is much the same as cvs - just cd into your working copy and run "svn up".

Some links to lern more about dowloading Scribus and about SVN:
 * There is an online reference for SVN at this site.
 * Once you have subversion installed, you can get some help for SVN at the command line by entering svn help
 * See the installing section on docs.scribus.net for more info on the Official Documentation site.
 * Craig Ringer explained how to use SVN with Scribus on the list.

Thanks to Anduin.net [], anonymous SVN access is updated daily.

More info on downloading scribus:
 * Standard download
 * CVS download

If you are compiling for the first time, don't be scared of the command line. Just copy the lines relevant to the version of Scribus you want to use, one by one on the command line.

Watch out:
 * Newbies, should take care, that only 'make install' part has to be done as a root. Rest of the part, like downloading and compiling can be done easily as a normal users.
 * And if u already have a version of Scribus on your system, don't forget to use the option WANT_VERSIONING=1. You can specify this option as -DWANT_VERSIONING=1.

Good luck!

Why Do I Have to 'Build' Scribus?
For that matter, what is Building?

When you are going to build or compile Scribus, what you have downloaded is a large collection of plain-text files (ending in '.c' or '.cpp' to denote either the C or C++ language respectively). The reason there are so many is that this actually makes the process of developing software easier, and allows for use of small parts repeatedly by different functions of the overall program. These plain-text files need to be converted to binary files (ending in ',o' for object files) so that your PC can use them, and the program works efficiently.

The first step is to configure your downloaded directory of files. This requires a check of your PC to make sure the compiling programs and all the other required outside resources are present and sufficiently up-to-date. Just as Scribus itself consists of these small program files, it also will use those of outside programs, like CUPS, lcms, and so on, so it needs to have on hand those plain text files to connect to these outside resources. After checking for the necessary resources, a script is written to tell the compiler how to go about building Scribus. The process will fail if you are missing something, and cmake will give you error messages.

The Scribus Team now encourages the use of cmake for this configuring process. It is quick, easy to use, and easy for the developers to write for -- even cmake needs instructions. You can also pass to cmake several special parameters for your particular PC setup, where you want Scribus to be installed, for example.

Next, the actual 'build' process is done with a program called make. To start the process you simply enter make in a command line. That's it. You do not need to have root privileges to compile, and it is generally recommended that do not compile as root (one reason for this is that, by creating a number of files under root's name, you then interfere with subsequent updating from CVS). Compiling takes up a good part of your computer's resources, especially your processor(s), so you will find its performance rather sluggish while compiling is going on. Consequently, many find that compiling is best done by starting make and then walking away from the PC to let it do its work.

Finally, you need to install, done with the command make install. If you are going to install in the default location, you will need to have root privileges. On most Linux distros this can easily be done with the su command (after which you need root's password), or with sudo, entered as sudo make install. You can run cmake with a command that can install Scribus in a directory for which you have write privileges, and therefore do not need to be  root.

For this help, and other advice, continue reading the following sections.

To start the build
Before continuing, please note that an out-of-source build is recommended, however.. From the Scribus directory:

For example:

Some options that the Scribus CMake files know about (more to come!):
 * WANT_VERSIONING=1: Sets the build to use the VERSION setting as a suffix for the install directories and the binary. Eg, the binary could be . This should mean that you can install multiple versions with the same prefix with no clashes.
 * WANT_DEBUG=1: Sets the build to be a debug release and use -O0 -g3, instead of -O2 (This is the default for now, and cannot be turned off unless you edit the CMakeFiles.txt file).
 * WANT_CAIRO=1: Makes CMake search for cairo and build with cairo instead of LibArt_LGPL. Please note we still consider the cairo build as beta.
 * WANT_LIBART=1 (default): Makes CMake search for and build with LibArt_LGPL instead of cairo.

For example: to make a cairo debug build, then something like this:

Out-of-source builds
One of the advantages of CMake is that you can do an out-of-source build. What is this? It enables you to build the application without writing anything at all to the directory where the Scribus source is. This means your source tree is clean, always. Its easier and faster to update, and you can build multiple targets out-of-source from the same source tree. Cool!

To do an out-of-source build, you need a new directory to build in. Say you have the source files in:

Make the following directory:

So then, instead of doing:

you would then change to the builddir directory and run:

Simple!

Continuing on to the build stage
Once this has successfully completed, simply run.

The CMake based build system is very new to Scribus and it will change and it will need improving. Please report issues on our mailing list or bugtracker.

There is a long todo list for this build system including, but not limited to:
 * Checking it works across distributions
 * Checking it works across various flavours of UNIX
 * Checking it works on 64 bit distros
 * Add Win32 and Mac OSX support

Compilation fails using Qt4 binaries
Systems with both Qt3 and Qt4 installed: You have  and   from Qt4 in the path and it may results to the compilation crash. This should NOT be the case with cmake 2.4.2 when released, or when using current Scribus CVS. However, this might be a useful workaround:

Remove cached options from previous cmake configuration run:

Then change PATH variable (for my Gentoo) e.g.:

And run cmake config phase again:

eg

Specific library locations
Whenever your distribution releases their package for a library Scribus depends on, it may still not be the very latest stable or unstable version from the writers of the library. In some cases, the Scribus developers have had to rely on the very latest code to further some parts of Scribus. In this case it is necessary to build your own version of such a library.

On example of this is the cairo graphics library. Right now, 1.3.4cvs has the capability to use the very very latest code from the just released cairo 1.2.

To specify a new cairo install path, other than your system's default add this to the cmake command line:

Making a tarball for distribution
To make a tarball for distribution, the old way would be to. The new way is to run  or   to give you a bundle of the source. With cmake 2.4.1 there is only support for a gzip  however a bzip2   is possible with later versions of cmake.

Notes For Packagers
If you package Scribus for a distribution keep in mind the issue of the install prefix versus temporary install directory prefix. The following seems to work well for Debian packaging:

then

where $(BUILD_DIR) is ./build and $(INSTALL_DIR) is ./install

Using $(PREFIX) is the key to avoiding hardcoded absolute path problem.

TODO

 * Enable more pkg-config usage
 * 64 bit supoprt
 * Prefixes for more packages
