[Opensync-users] problems compiling multisync-gui

[<li...@bl...>]

Hello,

i try to set up opensync 0.33 on my arch linux box.
Compiling and installing libsyncml,wbxml2,libopensync,libopensync-plugin-file,
libopensync-plugin-syncml,libopensync-plugin-vformat seemed to work.
Multisync-gui 0.90.17 has a problem:

checking for glib-2.0 opensync-1.0 osengine-1.0... Package osengine-1.0 was not found in the pkg-config search path. Perhaps you should add the directory containing `osengine-1.0.pc' to the PKG_CONFIG_PATH environment variable No package 'osengine-1.0' found
configure: error: Library requirements (glib-2.0 opensync-1.0 osengine-1.0) not met; consider adjusting the PKG_CONFIG_PATH environment variable if your libraries are in a nonstandard prefix so pkg-config can find them.
make: *** No targets specified and no makefile found.  Stop.

Where do i get opensync-1.0 from?
I haven't found any such package in your download folder.
thx
