This project uses GitHub Submodules to include the RISC-V docs-resources project to achieve a common look and feel.
When cloning this repository for the first time, you must either use
git clone --recurse-submodules or execute git submodule init and git submodule update after the clone to populate the docs-resources directory. Failure to clone the submodule, will result
in the PDF build fail with an error message like the following:
$ make asciidoctor-pdf \ -a toc \ -a compress \ -a pdf-style=docs-resources/themes/riscv-pdf.yml \ -a pdf-fontsdir=docs-resources/fonts \ --failure-level=ERROR \ -o profiles.pdf profiles.adoc asciidoctor: ERROR: could not locate or load the built-in pdf theme `docs-resources/themes/riscv-pdf.yml'; reverting to default theme No such file or directory - notoserif-regular-subset.ttf not found in docs-resources/fonts Use --trace for backtrace make: *** [Makefile:7: profiles.pdf] Error 1
The final specification form of PDF can be generated using the make command.
