## Introduction

These instructions explain how to build and install the source code of Version 9.4 of Icon under Unix. For instructions on installing a binary release, see Installing Icon Binaries.

These instructions assume that you have unpacked the Icon distribution file into a directory. All commands are issued in that directory.

## Configuring

The Icon source package contains configurations for a variety of Unix platforms. Type `make Configure` to see the list of known configurations. A status report for any system can be viewed by entering

> `make Status name=`name

Choose the configuration name that matches your system's operating system, and be sure to note any special considerations given in its status report.

(If your system is not among those listed, you will need to port the code. This is usually a fairly simple matter that involves copying an existing configuration and editing it to match the target system. See Porting Icon.

Most Unix systems include the X11 window system; type

> `make X-Configure name=`name

to configure Icon with graphics. If your computer does not have the X window system, type

> `make Configure name=`name

to configure Icon without graphics.

Installation using any of the supplied configurations should be routine, but some of those were contributed for systems we cannot test, and it is possible that some minor tweaking may be required. If so, or if you develop a new configuration, we'd like to hear about it by e-mail to icon-project@cs.arizona.edu.

## Building

After Configuring, type `make` to build the Icon system. This single step now builds:

- The Icon translator and interpreter
- Program library procedures
- VIB and other graphics utilities, if graphics are enabled

There may be a few warnings on some platforms, but there should be no fatal errors. If there are problems, fix them in the `config/`platform directory and repeat the configuration step.

## Testing

To verify a successful build, type `make Test`. This command compiles and executes a series of Icon programs, comparing their outputs with a set of standard results. A normal run concludes with the phrase "All tests passed."

A successful graphics build can be confirmed by executing `bin/colrbook`, the color book utility, with no arguments. It should display a spectrum of colors along the left and a set of recessed panes to the right. Click anywhere on the spectrum to fill colors in the panes. Click `QUIT` (in the upper left corner) to exit.

## Installing

Icon can be run directly from the location in which it was built. To do this, simply add the `bin` directory to your shell's search path. See the man pages for `icon` and `icont` for instructions on building and running Icon programs.

If you wish to install the binaries elsewhere, choose a location for a directory dedicated to Icon — for example, `/opt/icon` or `/usr/local/icon`. If you are replacing an existing directory, delete the old one first. Enter

> `make Install dest=`directory

to create directory and install Icon in its `bin`, `lib`, `doc`, and `man` subdirectories. All files are created using the default permissions (umask) of the current user.

You can make symbolic links from other locations to programs in the Icon `bin` directory. For example, you can link `/usr/local/bin/icon` to `/opt/icon/bin/icon`. If you do this, link all of `icon`, `icont`, `iconx`, and (if present) `vib`.

If you'd like to bundle up a gzipped tar file of the binaries created by the build process, enter `make Package`. Such a package can be used to install binaries on other systems of the same architecture.

## Cleaning Up

Type `make Clean` to remove intermediate files created during the build process. This command preserves the contents of the `bin` and `lib` directories, so the built system remains functional.

To restore everything to its original state, type `make Pure`. This removes all the configuration information and newly built files.
