Make-Index doesn,t work

[Thorsten Körner]

Hi
I´m using LyX 1.1.6fix1 on a Mandrake 8.0-System.
Everything works really fine with LyX, but the Index doesn´t appear in 
PDF-Files (either using the Way with ps2pdf nor pdftex)
Is there anybody out there, who has an idea or solution ?
Thank You for help 
CU
