--- Comment #2 from David Malcolm <dmalcolm at gcc dot gnu.org> --- make pdf is looking for the images in: gcc/jit/docs/_build/texinfo/libgccjit-figures but they're in the source tree in: gcc/jit/docs/_build/texinfo I just tried: git mv gcc/jit/docs/_build/texinfo/*.png gcc/jit/docs/_build/texinfo/libgccjit-figures and it seems to fix the "make pdf" for me. Will test a bit more.
