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.

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 or 12.2 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)::

  zypper ar http://download.opensuse.org/repositories/isv:/ownCloud:/devel:/mingw:/win32/openSUSE_12.1/isv:ownCloud:devel:mingw:win32.repo
  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-iniparser-devel \
                 mingw32-libsqlite-devel mingw32-dlfcn-devel mingw32-libssh2-devel \
                 kdewin-png2ico mingw32-libqt4 mingw32-libqt4-devel mingw32-libgcrypt \
                 mingw32-libgnutls mingw32-libneon mingw32-libneon-devel mingw32-libbeecrypt \
                 mingw32-libopenssl mingw32-openssl mingw32-libpng-devel mingw32-libsqlite \
                 mingw32-qtkeychain mingw32-qtkeychain-devel mingw32-iniparser 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)::

  rpm -ihv http://pmbs.links2linux.org/download/mingw:/32/openSUSE_12.1/x86_64/mingw32-cross-nsis-plugin-processes-0-1.1.x86_64.rpm
  rpm -ihv http://pmbs.links2linux.org/download/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/freitag/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 'dav' branch in the newly checked out
`ocsync` directory::

  cd ocsync
  git checkout dav

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 ``iniparser``, ``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``.
