Lilypon-book and pdftex question

[Carlos]

I am trying to use lilypond-book with pdftex.   The way I use pdftext is to launch it from a Miktex a Windows interface and editor for the Latex family wich runs very nicely.   I have done lilypond-book on a .tex file and then taken the .latex file and the lily-xxxxxx.tex file and try to run it from my shell and it does not go.   Is there a way to take the lily-xxxx.tex file and simply input into the main .tex file?   Do I need a package declaration or something? or does pdftex understand all what is inside the lily-xxxxxxxx.tex file ?   Here is a transcription of my original file and the log   \documentclass[a4paper,12pt,oneside, titlepage]{book} \usepackage[pdftex]{graphicx} % para incluir gráficos \begin {document} \chapter {Lilypond try} Vamos a ver si es posible insertar archivos de Lipyond en el texto \begin[26pt]{lilypond} c' d' e' f' g'2 g'2 \end{lilypond}   \end{document}   =============== and this the log Chapter 1. ! Undefined control sequence. l.8 {\preLilypondExample \input lily-1415224753.tex \postLilypondExample ? ! Emergency stop. l.8 {\preLilypondExample \input lily-1415224753.tex \postLilypondExample End of file on the terminal! No pages of output.   ==========   Thanks for any help Carlos
