The generated Info documentation is included in the distribution
tar files and in the Git source code repository; you should
not need to rebuild it. However, if it needs to be done, simply running
make will do it, assuming that you have a recent enough version
of makeinfo installed.
If you wish to build the PDF version of the manuals, you will need
to have TeX installed, and possibly additional packages that
provide the necessary fonts and tools, such as dvi2pdf
and ps2pdf. You will also need GNU Troff (groff)
installed in order to format the reference card and the manual page
(see Contents of the gawk Distribution). Managing this process is beyond the
scope of this Web page.
Assuming you have all you need, then the following commands produce the PDF versions of the documentation:
cd doc make pdf
This creates PDF versions of all three Texinfo documents included in the distribution, as well as of the manual page and the reference card.
Similarly, if you have a recent enough version of makeinfo,
you can make the HTML version of the manuals with:
cd doc make html
This creates HTML versions of all three Texinfo documents included in the distribution.
