Appendix A: Building the Client
===============================

This section explains how to build the ownCloud Client from source
for all major platforms. You should read this section if you want
to development on the desktop client.

Note that the building instruction are subject to change as development 
proceeds. It is important to check the version which is to built.

This instructions were updated to work with ownCloud Client 1.5.

Linux
-----

1. Add the `ownCloud repository from OBS`_.
2. Install the dependencies (as root, or via sudo):

  * Debian/Ubuntu: ``apt-get update; apt-get build-dep owncloud-client``
  * openSUSE: ``zypper ref; zypper si -d owncloud-client``
  * Fedora/CentOS: ``yum install yum-utils; yum-builddep owncloud-client``

3. Follow the `generic build instructions`_.

Mac OS X
--------

Next to XCode (and the command line tools!), you will need some
extra dependencies.

You can install these dependencies via MacPorts_ or Homebrew_.
This is only needed on the build machine, since non-standard libs
will be deployed in the app bundle.

The tested and preferred way is to use HomeBrew_. The ownCloud team has
its own repository which contains non-standard recipes.  Add it with::

  brew tap owncloud/owncloud

Next, install the missing dependencies::

  brew install $(brew deps ocsync) 
  brew install $(brew deps mirall)

  
To build mirall and csync, follow the `generic build instructions`_.

.. note::
  You should not call ``make install`` at any time, since the product of the
  mirall build is an app bundle. Call ``make package`` instead to create an
  install-ready disk image.

Windows (cross-compile)
-----------------------

Due to the amount of dependencies that csync entails, building the client
for Windows is **currently only supported on openSUSE**, by using the MinGW
cross compiler. You can set up openSUSE 12.1, 12.2 or 13.1 in a virtual machine
if you do not have it installed already.

In order to cross-compile, the following repositories need to be added
via YaST or ``zypper ar`` (adjust when using openSUSE 12.2 or 13.1)::

  zypper ar http://download.opensuse.org/repositories/windows:/mingw:/win32/openSUSE_12.1/windows:mingw:win32.repo
  zypper ar http://download.opensuse.org/repositories/windows:/mingw/openSUSE_12.1/windows:mingw.repo

Next, install the cross-compiler packages and the cross-compiled dependencies::

  zypper install cmake make mingw32-cross-binutils mingw32-cross-cpp mingw32-cross-gcc \
                 mingw32-cross-gcc-c++ mingw32-cross-pkg-config mingw32-filesystem \
                 mingw32-headers mingw32-runtime site-config mingw32-libqt4-sql
                 mingw32-libqt4-sql-sqlite mingw32-libsqlite-devel \
                 mingw32-dlfcn-devel mingw32-libssh2-devel kdewin-png2ico \
                 mingw32-libqt4 mingw32-libqt4-devel mingw32-libgcrypt \
                 mingw32-libgnutls mingw32-libneon-openssl mingw32-libneon-devel \
                 mingw32-libbeecrypt mingw32-libopenssl mingw32-openssl \
                 mingw32-libpng-devel mingw32-libsqlite mingw32-qtkeychain \
                 mingw32-qtkeychain-devel mingw32-dlfcn mingw32-libintl-devel \
                 mingw32-libneon-devel mingw32-libopenssl-devel mingw32-libproxy-devel \
                 mingw32-libxml2-devel mingw32-zlib-devel

For the installer, the NSIS installer package is also required::

  zypper install mingw32-cross-nsis

..  Usually, the following would be needed as well, but due to a bug in mingw, they
    will currently not build properly from source.

    mingw32-cross-nsis-plugin-processes mingw32-cross-nsis-plugin-uac

You will also need to manually download and install the following files with
``rpm -ivh <package>`` (They will also work with openSUSE 12.2 and newer)::

  rpm -ihv http://download.tomahawk-player.org/packman/mingw:32/openSUSE_12.1/x86_64/mingw32-cross-nsis-plugin-processes-0-1.1.x86_64.rpm
  rpm -ihv http://download.tomahawk-player.org/packman/mingw:32/openSUSE_12.1/x86_64/mingw32-cross-nsis-plugin-uac-0-3.1.x86_64.rpm

Now, follow the `generic build instructions`_, but pay attention to
the following differences:

1. For building ``libocsync``, you need to use ``mingw32-cmake`` instead
   of cmake.
2. for building ``mirall``, you need to use ``cmake`` again, but make sure
   to append the following parameter::
3. Also, you need to specify *absolute pathes* for ``CSYNC_LIBRARY_PATH``
   and ``CSYNC_LIBRARY_PATH`` when running ``cmake`` on mirall.

  ``-DCMAKE_TOOLCHAIN_FILE=../mirall/admin/win/Toolchain-mingw32-openSUSE.cmake``

Finally, just build by running ``make``. ``make package`` will produce
an NSIS-based installer, provided the NSIS mingw32 packages are installed.

Generic Build Instructions
--------------------------
.. _`generic build instructions`

The ownCloud Client requires Mirall and CSync_. Mirall is the GUI frontend,
while CSync is responsible for handling the actual synchronization process.

At the moment, ownCloud Client requires a forked version of CSync. Both
CMake and Mirall can be downloaded at ownCloud's `Client Download Page`_.

If you want to build the leading edge version of the client, you should
use the latest versions of Mirall and CSync via Git_, like so::

  git clone git://git.csync.org/users/owncloud/csync.git ocsync
  git clone git://github.com/owncloud/mirall.git

Next, create build directories::

  mkdir ocsync-build
  mkdir mirall-build

This guide assumes that all directories are residing next to each other.
Next, make sure to check out the branch called 'ocsync' in the newly checked out
`ocsync` directory::

  cd ocsync
  git checkout ocsync

The first package to build is CSync::

  cd ocsync-build
  cmake -DCMAKE_BUILD_TYPE="Debug" ../ocsync
  make

You probably have to satisfy some dependencies. Make sure to install all the
needed development packages. You will need ``sqlite3`` as well as ``neon`` for 
the ownCloud module. Take special care about ``neon``. If that is missing, the 
cmake run will succeed but silently not build the ownCloud module.

``libssh`` and ``libsmbclient`` are optional and not required for the client
to work. If you want to install the client, run ``make install`` as a final step.

Next, we build mirall::

  cd ../mirall-build
  cmake -DCMAKE_BUILD_TYPE="Debug" ../mirall \
        -DCSYNC_BUILD_PATH=/path/to/ocsync-build \
        -DCSYNC_INCLUDE_PATH=/path/to/ocsync/src

Note that it is important to use absolute pathes for the include- and library
directories. If this succeeds, call ``make``. The owncloud binary should appear
in the ``bin`` directory. You can also run ``make install`` to install the client to
``/usr/local/bin``.

To build an installer/app bundle (requires the mingw32-cross-nsis packages on Windows)::

  make package

Known cmake parameters:

* WITH_DOC=TRUE: create doc and manpages via running ``make``; also adds install statements to be able to install it via ``make install``.
