Hi all, In the current master (a727e7d4d398375c4a3ba5020e2ab25b5b874785), INSTALL contains: For Debian and similar: sudo apt-get install libxapian-dev libgmime-3.0-dev libtalloc-dev zlib1g-dev python-sphinx However it seems like what is currently used is python3-sphinx, cf commit 03f4f75124c6d9882b8306873e8908aac9eee2bb. At least on my system, when I have just python-sphinx installed instead of python3-sphinx, ./configure says it will not build man pages, whereas it works with python3-sphinx. So I think the line above should be changed. Probably the Fedora line just below needs to be changed too, but I don't know how their packaging work (do they have a python3-sphinx package or not). Thanks! -- Antoine Amarilli
