Sphinx pdfbuilder format not resolved, probably missing URL

Question

I am trying to generate a pdf using rst2pdf, but keep getting the error "format not resolved, probably missing URL or undefined destination for target".

I use sphinx to generate the .rst files and am able to generate the HTML output just fine.

To generate the pdf I followed the instructions at: https://gist.github.com/alfredodeza/7fb5c667addb1c6963b9

Answer 1

If you are still getting this message in 2021, it likely means rst2pdf can't figure out where one or more of your links is pointed. For example, I had in-page nav links in my .rst code like this that were ok when building HTML but causing the error referred to by the OP during PDF generation:

`Back to top ↑ <#top>`_

The most reliable solution seems to be to remove these in-page links.

Alternatively, you could just convert these implicit links to raw html blocks like below, which could be a solution if you can get rst2pdf to render raw html using xhtml2pdf (this isn't working for me, but perhaps someone else can get it).

.. |top| raw:: html

   <a href="#top">Back to top ↑</a>

|top|

Note that in this alternative solution, the in-page links probably will not work in most PDF viewers, so this is really only a solution to get .rst files to compile to both PDF and HTML (as the OP asked), rather than one that will allow identical behavior.

Answer 2

This has now been resolved in rst2pdf via PR 619.

You can install the version of rst2pdf that has this fix by doing this:

$ cd {some directory where you keep 3rd-party projects, e.g. ~/projects}
$ git clone https://github.com/rst2pdf/rst2pdf.git
$ cd rst2pdf
$ python setup.py install
