Thanks for the instructions.

sudo apt update

sudo apt install texlive-latex-extra

sudo apt install dvipdf

sudo apt install ghostscript

sudo apt install texinfo

git clone https://git.savannah.gnu.org/git/c-intro-and-ref.git

cd c-intro-and-ref

make c.pdf

makeinfo --html -v c.texi -o c.html --no-split

With Docker:

  mkdir -p out.d ; chmod 1777 out.d
  docker run --rm -it -v "$(pwd)/out.d:/out.d" \
    debian:latest \
    sh -c "
        apt update && apt install --no-install-recommends -y \
          texlive-latex-extra \
          texlive-base \
          ghostscript \

        && cd c-intro-and-ref \
        && make c.pdf \
        && makeinfo --html -v c.texi -o /out.d/c.html --no-split
    "

With Guix:

    guix shell --pure git texinfo make nss-certs
    [env] $ git clone https://git.savannah.gnu.org/git/c-intro-and-ref.git
    [env] $ cd c-intro-and-ref
    [env] $ make c.info

...and read it in your Info reader; I recommend Emacs (C-u h i /path/to/c RET).

PDF is inferior because it doesn't have a convenient way to access the curated concept or variable index, whereas in Info you can just hit "i" and type something like "array, layout in memory" and jump straight to the relevant paragraph.

I ran these after creating a docker container on my mac.

> docker run -t -i -v $HOME/docker-mounted:/tmp ubuntu /bin/bash

And copy the c.pdf from /tmp in docker to my local mac.

> sudo apt install dvipdf

There's no such package.

I think the package texlive-base or texlive-latex-extra includes dvips (for PostScript), which provides the dvipdf command.
