This book is an old presentation. The newer book that I've actually used and tested in the classroom is Fundamentals of Calculus. ================================================================= producing pdf output ================================================================= Compiling the book into pdf format is fairly easy on a Linux machine. Basically you just need to install some open-source software. The following are the relevant packages on a Debian-based system such as Ubuntu: texlive-full gnuplot qpdf m4 inkscape imagemagick libjson-ruby libjson-perl (version 2.0 or higher) ruby 1.9.2 or higher Go to the main directory (the one where you found this README). Do make setup This will check that you have at least ruby 1.9 and set all the scripts to be executable. If you're running Inkscape 0.93 or later, change --export-pdf in the Makefile to --export-filename. Then: make figures make book I haven't tried compiling the books on MacOS X or Windows. I suspect it could be done on MacOS X without any heroic measures, and I suspect that it would be a real pain on Windows.
