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)

bug: 
iniparser is not provideed by $(brew deps ocsync)
fix with brew install iniparser

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

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

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.
