I have created a source RPM package where I do use the following code
in the %install section:

make DESTDIR="%{buildroot}" install-strip

%suse_update_desktop_file -c wxWrapper "Rapid Database GUI Designer"
"Database designer based on wxWrapper" %{prefix}/bin/wxWrapper %
{prefix}/share/lbdmf/lbdmf.png Development

I will get this error (german):

suse_update_desktop_file: Ungültige Option -- c

On SuSE 9.1 Professional this works and I do not see any differences
in the macro shell script.

Any ideas ?

Thanks, Lothar
