Just guessing, but is the old PDF open in a separate viewer? Some viewers lock the file and Lilypond won't be able to overwrite the old one until the file is closed in the viewer.
The other possible thing I can think of is saving the input file first, then compiling it. If you don't save, the PDF file goes to a temporary location. When you save it, it puts the PDF in the same folder as the input file. Hope that helps, Abraham On Thu, Oct 20, 2022 at 2:09 PM thedoctor81877--- via LilyPond user discussion <lilypond-user@gnu.org> wrote: > I have a lilypond file, and I changed the title and subtitle and > recompiled using Frescobaldi; however, I now am not getting a pdf file > created. > > I am using: > > Frescobaldi 3.2 > Lilypond 2.22.2 > Pop OS 22.04 > > Thanks, > > Michael D > > -- > Sent with Tutanota, enjoy secure & ad-free emails. >
