This is the new build system for the various wolfSSL products' manuals, please see the READMEs each directory for more information. The advantages of this over previous wolfSSL manuals are:

• Has a possible code review process
• Can automatically generate PDF and HTML output
• Has cross links between parts of the documentation
• Has links to the required API parts

To build the documentation you will need Docker running on your system. In this documentation root directory run make to build the documentation for every project which will output in a build subdirectory of this root directory (note: on some systems you may need to use sudo before make). You can also build individual project manuals by doing:

• make wolfssl
• make wolfssh
• make wolfboot
• make wolfclu
• make wolfcrypt-jni
• make wolfmqtt
• make wolfsentry
• make wolfssl-jni
• make wolftpm
• make porting
• make fips-ready

There is a CONTRIBUTING.md document which outlines how to add manuals to the tree.

If you are not building using the Docker build system above you can build using Ubuntu, this will require around 3GB of packages to be installed:

sudo apt install pandoc texlive-full mkdocs doxygen

You also need Doxybook2 installed which can be found at: https://github.com/matusnovak/doxybook2. Unfortunately there is no package for this. Installation instructions can be found at: https://github.com/matusnovak/doxybook2#Install. You'll likely have to checkout to this commit 1e5f8f0879aa1e908ccce250.

If Doxybook2 is installed in a non-stardard path you can use the environment variable DOXYBOOK_PATH to set it.

When in each manual directory to build the PDF:

make pdf

To build the HTML:

make html

To build both:

make

To run a local HTML server (HTML is built to a temporary area for this):

make serve

By default, the built output documentation is in English. If you assign a language code to the DOC_LANG variable and call 'make' with it, the output will be localized in that specified language. As of now (end of 2022), the only supported language code is 'JA', which means 'Japanese'. Not all wolfSSL products documentation supports localization. 'make' with DOC_LANG variable for unsupported products is ignored and output in English.

make DOC_LANG=JA

For localization to work, the build environment must have the correct fonts installed for the specified language.

'Noto Sans CJK JP' font is used for Japanese localization. You can get the font files from the following Github repository: https://github.com/googlefonts/noto-cjk/tree/main/Sans/OTF/Japanese

You can download the seven NotoSansCJKjp-xxx.otf files from there and put them into /usr/local/share/fonts. You may need 'sudo' for the operation. After coping font files, you need to update font cache by calling:

sudo fc-cache -fv

Then you can confirm the font cache includes the installed font files by 'fc-list'.

fc-list | grep NotoSansCJKjp

You will get the list of installed font files.
