[Ekiga-list] Cross-compilation error

[Vnum]

Hello i want to cross-compil ekiga for win32 on linux

I have the following configuration :
- Ubuntu 7.04
- svn version : 1.4.3
- make version : 3.81

the svn check-out is working with next command :
svn co http://svn.gnome.org/svn/ekiga/trunk/win32

But the make update-sources give me this following error :

/bin/sh: Syntax error: "(" unexpected
make: *** [updat-sources] Erreur 2


You have any ideas to resolv this problem ?

Thanks for your help.
Regards.
