Or the the generated refs are absurd ;) I haven't found the technical problem in detail, but I made some test and this is what I observed; Sometimes even a "clean": make DOCBOOKS= clean htmldocs fails with recursion error. I also realized that this behavior is only about the generated ABI docs. So I looked at what the Perl script generates: ./scripts/get_abi.pl rest --dir Documentation/ABI/testing It generates horrible titles, containing more than 4000 characters! I mean titles like the one shown in "<SNIP/SNAP: title>" below. Which ends in HTML links like the one below. OK, we can discuss why Sphinx have problems handling such titles and refs but: at this point I stop digging any deeper ;) IMO: this is not the way, we can include ABI into the reST doc -- Markus -- A
