If you're desiring to build PDF outputs, it is recommended to use version 1.4.6 or upper. +Most distributions are shipped with Sphinx, but its toolchain is fragile, +and it is not uncommon that upgrading it or some other Python packages +on your machine would cause the documentation build to break. + +A way to get rid of that is to use a different version than the one shipped +on your distributions. In order to do that, it is recommended to install +Sphinx inside a virtual environment, using ``virtualenv-3`` +or ``virtualenv``, depending on how your distribution packaged Python 3. + +.. note:: + + #) Sphinx versions below 1.5 don't work properly with Python's + docutils version 0.13.1 or upper. So, if you're willing to use + those versions, you should run ``pip install 'docutils==0.12'``. + + #) It is recommended to use the RTD theme for html output. Depending + on the Sphinx version, it should be installed in separate, + with ``pip install sphinx_rtd_theme``. + +In summary, if you want to install Sphinx version 1.4.9, you should do:: + + $ virtualenv sphinx_1.4 + $ . sphinx_1.4/bin/activate + (sphinx_1.4) $ pip install 'docutils==0.12' + (sphinx_1.4) $ pip install 'Sphinx==1.4.9' + (sphinx_1.4) $ pip install sphinx_rtd_theme + +After running ``. sphinx_1.4/bin/activate``, the prompt will change, +in order to indicate that you're using the new environment. If you +open a new shell, you need to rerun this command to enter again at +the virtual environment before building the documentation. + .. note:: Please notice that, for PDF and LaTeX output, you'll also need ``XeLaTeX`` -- 2.13.0 -- To unsubscribe from this list: send the line "unsubscribe linux-doc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
