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

Follow the generic build instructions.

You can install the missing 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 only exception to this rule is libiniparser, which lacks a decent build system. If you are using Homebrew, you can just add it:

brew tap dschmidt/owncloud
brew install iniparser

Otherwise, you need to copy the header and lib files to /usr/local/include and /usr/local/lib respectively.

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):

http://download.opensuse.org/repositories/isv:/ownCloud:/devel:/mingw:/win32/openSUSE_12.1/isv:ownCloud:devel:mingw:win32.repo
http://download.opensuse.org/repositories/windows:/mingw/openSUSE_12.1/windows:mingw.repo
http://download.opensuse.org/repositories/windows:/mingw:/win32/openSUSE_12.1/windows:mingw:win32.repo

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

zypper si -d mingw32-csync
zypper si -d mingw32-owncloud-client 

Now, follow the generic build instructions, but make sure to append the following parameter to both cmake calls:

-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 buidld is CSync:

cd ocsync-build
cmake -DCMAKE_BUILD_TYPE="Debug" -DLOG_TO_CALLBACK=ON -DWITH_LOG4C=OFF ../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. 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_LIBRARY_PATH=../ocsync-build \
      -DCSYNC_INCLUDE_PATH=../ocsync/src

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.
