What other info should I provide you?

This error seems to indicate HAVE_CAIRO_PDF is not defined in your build, see [1].

This indicates two problems:
- For once the optional code does not seem to be properly protected by
  pre-processor directives anymore as the whole idea is to allow Inkscape
  to compile even if HAVE_CAIRO_PDF is undefined
- More generally and unrelated to Inkscape itself it seems your cairo
  was built without CAIRO_HAS_PDF_SURFACE. While not an actual error
  it seems unlikely it should be packaged like that in Ubuntu 18.10, so
  unless you built cairo yourself you should report the error to
  Ubuntu packagers.

A fix to allow compilation without cairo-pdf.h has been merged into master: https://gitlab.com/inkscape/inkscape/merge_requests/494
