pdfpages

[Myriam Abramson]

Hello,

I need to include some pdf pages in my output.
I've set
\usepackage{pdfpages} 
in the preamble.

Then I have at the end of my lyx file:
\includepdf[pages=-] {filename.pdf}

I get the error message to set \pdfoutput=1 when trying to view with
ps2pdf. Where should I set pdfoutput? 

I'm not sure if I've done this correctly,

TIA,
--
