According to: grep-dctrl -n -w -F Build-Depends,Build-Depends-Indep -s Package doxygen-latex /var/lib/apt/lists/deb.debian.org_debian_dists_sid_main_source_Sources | sort | uniq | wc there are 60 packages that build-depend on doxygen-latex in sid.
The last time I run a full rebuild of build dependents from doxygen: https://lists.debian.org/debian-devel/2019/10/msg00260.html 10 packages were failing, all of them on latex issues. We can assume that of the 60 packages that build-depend on doxygen latex, probably 17% FTBFS. That's a lot, but I would not say that doxygen-latex is totally broken. Nor would I say that it is not supported by upstream anymore: of 1863 issues open upstream, 145 match on "latex", and I know for sure they are being worked upon (as was the one with longtabu that caused so many more failures). The issue with doxgen-latex is that both doxygen and latex are old, and the latter carries a few flaky plugins / dependencies. As always when integrating two software products, the total trouble is the product of the troubles caused by each of them. So the maintainer of doxygen is not going to unilaterally ask for removal of doxygen-latex and break 50 more packages out of the blue. Having said all that, I was tempted myself to open an issue upstream on "dropping support for latex output”. Personally I have never found any use for the bulky PDF files produced by doxyen-latex + pdflatex, the html doxygen output is more practical and easier to browse on any device. And nobody is supposed to print those nowadays ! So what shall we do with this ? Paolo
