An attempt at reproducible builds in LaTeX.
Run the bash script ./makepdfs.
This generates the following PDFs, copies them into their respective directories, and computes their SHA-256 sums:
empty.pdf(an empty A4 page)nonempty.pdf(a page-numbered but otherwise empty A4 page)quick.pdf(the quick brown fox jumps over the lazy dog)
Run the bash script ./makediffs.
Only empty.pdf appears to be reproducible.
The others (nonempty.pdf and quick.pdf) depend on the TeX distribution.
For TeX Live, there are 3 cliques in terms of reproducibility so far:
