Using preview-latex requires a version of Emacs compiled with image support.
Precompiled versions are available from https://ftp.gnu.org/gnu/emacs/windows/.
For an overview of precompiled versions of Emacs for macOS see for example https://www.emacswiki.org/emacs/EmacsForMacOS.
Most GNU/Linux distributions nowadays provide a recent variant of Emacs via their package repositories.
Compiling Emacs yourself requires a C compiler and a number of tools and development libraries. Details are beyond the scope of this manual. Instructions for checking out the source code can be found at https://savannah.gnu.org/git/?group=emacs.
Well, AUCTeX would be pointless without that. Processing documentation requires TeX, LaTeX and Texinfo during installation. preview-latex requires Dvips for its operation in DVI mode. The default configuration of AUCTeX is tailored for teTeX or TeXlive-based distributions, but can be adapted easily.
This is needed for operation of preview-latex in both DVI and PDF mode. Most versions of Ghostscript nowadays in use should work fine (version 7.0 and newer).
Recent AUCTeX uses GNU make specific capabilities in the Makefiles.
If your OS’s default make
command is not GNU make,
you have to obtain it in order to build AUCTeX by yourself. GNU make
is sometimes provided under the name gmake
in your
OS’s binary package system.

Strictly speaking, you can get away without it if you are building from the distribution tarball, have not modified any files and don’t need a printed version of the manual: the pregenerated info file is included in the tarball. At least version 4.0 is required.
For some known issues with various software, see Known problems in the preview-latex manual.
