Beej's Guide to C

Build Instructions


Mac dependencies install (reopen terminal after doing this):

xcode-select --install                  # installs make
brew install python                     # installs Python3
brew install pandoc
brew cask install mactex                # installs XeLaTeX
brew tap homebrew/cask-fonts
brew cask install font-liberation-sans  # installs sans, serif, and mono


  1. Type make from the top-level directory.

    If you have Gnu Make, it should work fine. Other makes might work as well. Windows users might want to check out Cygwin.

  2. Type make stage to copy all the build products and website to the stage directory.

  3. There is no step three.

You can also cd to the src directory and make.

make clean cleans, and make pristine cleans to "original" state.

To embed your own fonts in the PDFs, see the src/Makefile for examples.

The upload target in the root Makefile demonstrates the build steps for a complete release. You'll need to change the UPLOADDIR macro in the top-level Makefile to point to your host if you want to use that. You're free to upload whatever versions you desire individually, as well.

Pull Requests

Please keep these on the scale of typo and bug fixes. That way I don't have to consider any copyright issues when merging changes.

  • When pandoc 2.8 comes up, switch all man page subheaders to h3 and supress them from the table of contents.
