scripts/sphinx-pre-install: always check if version is compatible with build Call the script every time a make docs target is selected, on a simplified check mode. With this change, the script will set two vars: $min_version - obtained from `needs_sphinx` var inside conf.py (currently, '1.3') $rec_version - obtained from sphinx/requirements.txt. With those changes, a target like "make htmldocs" will do: 1) If no sphinx-build/sphinx-build3 is found, it will run the script on normal mode as before, checking for all system dependencies and providing install hints for the needed programs and will abort the build; 2) If no sphinx-build/sphinx-build3 is found, but there is a sphinx_${VER}/bin/activate file, and if ${VER} >= $min_version (string comparation), it will run in full mode, and will recommend to activate the virtualenv. If there are multiple virtualenvs, it will string sort the versions, recommending the highest version and will abort the build; 3) If Sphinx is detected but has a version lower than $min_version, it will run in full mode - with will recommend creating a virtual env using sphinx/requirements.txt, and will abort the build. 4) If Sphinx is detected and version is lower than $rec_version, it will run in full mode and will recommend creating a virtual env using sphinx/requirements.txt. In this case, it **won't** abort the build. 5) If Sphinx is detected and version is equal or righer than $rec_version it will return just after detecting the version ("quick mode"), not checking if are there any missing dependencies. Just like before, if one wants to install Sphinx from the distro, it has to call the script manually and use `--no-virtualenv` argument to get the hints for his OS: You should run: sudo dnf install -y python3-sphinx python3-sphinx_rtd_theme While here, add a small help for the three optional arguments for the script.

docs: drop the version constraints for sphinx and dependencies As discussed (see Links), there is some inertia to move to the recent Sphinx versions for the doc build environment. As first step, drop the version constraints and the related comments. As sphinx depends on jinja2, jinja2 is pulled in automatically. So drop that. Then, the sphinx-pre-install script will fail though with: Can't get default sphinx version from ./Documentation/sphinx/requirements.txt at ./scripts/sphinx-pre-install line 305. The script simply expects to parse a version constraint with Sphinx in the requirements.txt. That version is used in the script for suggesting the virtualenv directory name. To suggest a virtualenv directory name, when there is no version given in the requirements.txt, one could try to guess the version that would be downloaded with 'pip install -r Documentation/sphinx/requirements.txt'. However, there seems no simple way to get that version without actually setting up the venv and running pip. So, instead, name the directory with the fixed name 'sphinx_latest'. Finally update the Sphinx build documentation to reflect this directory name change.
