2. Building Documentation¶
To create a rendered copy of this documentation locally you can use the Sphinx tool to build and package the plain-text documents into HTML-formatted pages.
If you are building the documentation for the first time then you will need to check that you have the required software packages, as described in the Prerequisites section that follows.
An online copy of the documentation is available at https://www.trustedfirmware.org/docs/tf-a, if you want to view a rendered copy without doing a local build.
For building a local copy of the TF-A documentation you will need, at minimum:
Python 3 (3.5 or later)
PlantUML (1.2017.15 or later)
You must also install the Python modules that are specified in the
requirements.txt file in the root of the
docs directory. These modules
can be installed using
pip3 (the Python Package Installer). Passing this
requirements file as an argument to
pip3 automatically installs the specific
module versions required by TF-A.
An example set of installation commands for Ubuntu 18.04 LTS follows, assuming
that the working directory is
sudo apt install python3 python3-pip plantuml pip3 install [--user] -r requirements.txt
Several other modules will be installed as dependencies. Please review the list to ensure that there will be no conflicts with other modules already installed in your environment.
Passing the optional
--user argument to
pip3 will install the Python
packages only for the current user. Omitting this argument will attempt to
install the packages globally and this will likely require the command to be run
as root or using
More advanced usage instructions for pip are beyond the scope of this document but you can refer to the pip homepage for detailed guides.
2.2. Building rendered documentation¶
docs directory of the project, run the following commands. It is
important to note that you will not get the correct result if the commands are
run from the project root directory, as that would invoke the top-level Makefile
for TF-A itself.
make clean make html
