Re: lilypond-book: "Output would overwrite input file" error

[René Brandenburger]

Hi,

I had the same problem already when moving from 2.10.xx to 2.11.43. I
solved the problem by renaming all .tex files to .lytex and replacing
the \input(foobar.tex) by \input(foobar.lytex)

Hope this helps

best regards

rene
