 ===== Building Qt =====
-We build an alternative set of Qt libraries using the standard Qt 4.8 sources (4.8.1 and 4.8.3 will work fine), applying some patches and using an "embedded" configuration to remove the dependency on X.

-The patches we use are part of the Debian packaging we use to build packages for Ubuntu 12.04. These can be obtained from a git repository:

-The standard Debian package building process involves applying the patches found in the ''debian/patches'' directory to the Qt 4.8 sources then running the ''configure'' script in the way described in the ''debian/rules'' file.

+  git checkout 4.8-qpa
-==== Building on a Debian Derivative ====
+To build debian packages, we re-package the Qt4 source code to obtain the directory structure expected by the dpkg build tools, then extract the re-packaged source archive, copy in the ''debian'' directory from git git repository, and build packages with ''debuild'' or similar.
-If you are building on a Debian derived distribution, you can simply copy the ''debian'' directory from the ''qt4-headless'' directory into the Qt 4.8 source directory, enter the source directory and run debuild:
-<code>
-debuild -sa -uc -us
-</code>
-Note that, if you use the distribution's own source package, you will need to unpatch the sources first by running the debhelper script, dh_quilt_unpatch.
+Packages for some ubuntu releases are available from the [[https://launchpad.net/~met-norway/+archive/ubuntu/metapps|MET Norway PPA]].
-The result should be a package in the parent directory you can install using dpkg or aptitude.
 ==== Building on Other Distributions ====
-If you are building on another distribution, you will need to patch the files by hand. Enter the Qt 4.8 source directory and run a command of the following form on each of the patches in ascending numerical order; for example:

 Diana is typically only built for batch use on headless systems since the GUI is only useful when there is an attached display. This means that only the ''bdiana'' tool is built. The ''debian_bdiana'' directory supplied with the Diana sources contains information about the dependencies required for this configuration (in the ''control'' file) and the commands required to configure and build ''bdiana'' (in the ''rules'' file).
+Packages compiled for headless systems are available from the [[https://launchpad.net/~met-norway/+archive/ubuntu/metapps|MET Norway PPA]] for some ubuntu releases.

 Only a subset of the libraries mentioned on the [[autotools|Building Metlibs and Diana with Autotools]] page are required. Follow the instructions there to build and install Fimex and the miLogger, puCtools, puTools, miRaster and diField libraries.
