Hi, When running "make doc" in mercurial, I get: -------------- [...] mv common.txt.tmp common.txt python runrst hgmanpage --halt warning \ --strip-elements-with-class htmlonly hgrc.5.txt hgrc.5 abort: couldn't generate documentation: docutils module is missing please install python-docutils or see http://docutils.sourceforge.net/ make[2]: *** [Makefile:25: hgrc.5] Error 255 [...] ------------- I've just installed docutils by the book, that is, only for Python 3. So I tried adding PYTHON=python3 to all the "make" commands: ------------- make PYTHON=python3 build make PYTHON=python3 doc ------------- but I get: ------------- make -C doc make[1]: Entering directory '/sources/mercurial/mercurial-4.4.2/doc' python3 gendoc.py "hgrc.5" > hgrc.5.txt.tmp Traceback (most recent call last): File "gendoc.py", line 228, in <module> showtopic(ui, sys.argv[1]) File "gendoc.py", line 149, in showtopic helpprinter(ui, helptable + extrahelptable, None, include=[topic]) File "gendoc.py", line 158, in helpprinter ui.write(".. _%s:\n" % name) File "../mercurial/ui.py", line 904, in write self._write(*msgs, **opts) File "../mercurial/ui.py", line 912, in _write self.fout.write(a) TypeError: a bytes-like object is required, not 'str' make[1]: *** [Makefile:21: hgrc.5.txt] Error 1 make[1]: Leaving directory '/sources/mercurial/mercurial-4.4.2/doc' make: *** [Makefile:62: doc] Error 2 ------------ Clearly, gendoc.py is not Python 3 capable... So this means that generating the documentation requires Python 2, and since docutils is used, it should be compiled for Python 2 too...
