3. Installation

ERC may be compiled and installed on your machine.

This section may be skipped if you are using the version of ERC that comes with Emacs.

Compilation

This is an optional step, since Emacs Lisp source code does not necessarily have to be byte-compiled. It will yield a speed increase, though.

A working copy of Emacs or XEmacs is needed in order to compile ERC. By default, the program that is installed with the name emacs will be used.

If you want to use the xemacs binary to perform the compilation, you would need to edit `Makefile' in the top-level directory as follows. You can put either a full path to an Emacs or XEmacs binary or just the command name, as long as it is in the PATH.

EMACS    = xemacs
SITEFLAG = -no-site-file

Running make should compile the ERC source files in the `lisp' directory.

Installation

ERC may be installed into your file hierarchy by doing the following.

Edit the `Makefile' file so that ELISPDIR points to where you want the source and compiled ERC files to be installed and INFODIR indicates where to put the ERC manual. Of course, you will want to edit EMACS and SITEFLAG as shown in the Compilation section if you are using XEmacs.

If you are installing ERC on a Debian system, you might want to change the value of INSTALLINFO as specified in `Makefile'.

Run make as a normal user.

Run make install as the root user if you have chosen installation locations that require this.
