Let's assume that you have fetched the appropriate executables archives (if any) for your machine, together with the Documentation and Sources archive.

These archives are not simply a single executable for general use. Instead they are a (large) number of files, squished together into one file, and thus called an "archive". You have to go through a step which involves getting all the files out of the archive and into a folder on your machine.

We will give these instructions for four different kinds of systems, Windows, Mac OS X Macintoshes, Mac OS 8 or 9, and Linux or Unix systems. Then we will describe how to access the documentation after installing the package.

Our main method of distributing PHYLIP for Windows systems is in a self-extracting archive. A self-extracting archive has a small self-extraction program on its front, and when you run them as programs they extract themselves and write many files into your folder.

on a Windows95, Windows NT, Windows98, Windows 2000, Windows me, or Windows xp you will have a self-extracting archive called phylip3.67.exe. Place it in a folder where you will want PHYLIP to reside. It will make a folder called phylip3.67 there, inside the folder where you place the self-extracting archive. So if you place the archive on the Desktop, it will make that folder there.

To extract the archive simply double-click on it. If your Windows system does not allow the archive to self-extract, you may have to right-click on the archive and select "Run as administrator". Accept the default settings, and when a dialog box comes up, click on Unzip. When the extraction is complete, select Close. You will find the folder phylip3.67 in the same place as the archive.

After the self-extraction is done, you will find the phylip3.67 folder which has three folders within it, called doc, exe, and src. There is also a web page phylip.html. You should read this in your browser. It contains links to the main documentation web page main.html and to the other documentation pages and programs.

The archives for Intel iMac and PowerMac Mac OS X are in the Apple .dmg disk image format. There is one .dmg disk image distributed. It is 4 Megabytes in size, and is compressed; when uncompressed it is several times larger. Note that Mac OS X version 10.0 does not support compressed disk image files, so the .dmg file we distribute will not work on it.

It contains what looks like a normal folder called Phylip3.67, but you should not use the programs while they are in that folder. It is important that you use a copy of the contents of the disk image elsewhere on your system. Decide where the folder Phylip3.67 is going to reside, and copy that folder to that new location. Within it is all the source code, documentation, and executables.

The executables are "universal binaries" that will run on either the newer iMacs (which has Intel processors) or the older G3's, G4's or G5's that have PowerMac processors. (Basically they are each simply a pair of executables set up so that the processor chooses the right one and runs it).

Downloading the single Stuffit archive

The archives for Mac OS 8, Mac OS 9 Macintoshes are self-extracting archives. If you are fetching the files using a Web browser directly from your Mac, it will probably automatically invoke Stuffit Expander to unpack the archives into self-extracting archives. Self-extracting archives are archives with a small self-extraction program on their front, so that when they are run as programs they write a great many files into a folder.

Our default distribution is of a single large (4.9 Megabyte) Stuffit archive called phylip3.65.sit. This should automatically be unstuffed as it is downloaded. It contains the source code, documentation, and Mac OS executables.

However, at the moment we have reports of trouble running the unstuffed archives. Recent versions of Mac OS 9, and also the Classic environment under Mac OS X, seem to regard the executables files as text files, and they try to open them under SimpleText, which of course does not work.

Downloading multiple smaller Stuffit archives

Some people may wish instead to download these as a series of four archives. This might be necessary, for example, if you wanted to transfer them to a machine that was not connected to the Internet, and needed them each to be small enough to write onto a floppy disk.

If you choose to download these instead of the single Stuffit archive, and our system does automatically invoke Stuffit Expander, four self extracting archives will be created on your desktop, and their file names will end in .sit. If you have Stuffit Expander, you can use it to expand them.

Once the archives are downloaded and extracted, they will put folders on the desktop. One is called phylip and contains folders doc and src as well as a web page phylip.html. There are 307 files in all, as these include the documentation files, source code files, and compilation support files. You may have to be patient while the archive is being extracted.

The three archives of Macintosh Mac OS 8 and Mac OS 9 executables will create folders exe, exe.1, exe.2 and exe.3 on the desktop when they are extracted. For some reason we could not create these inside the phylip folder, but that is where these files need to be put. Do the following:

1. Move the exe folder inside the phylip folder.
2. Open the exe.1 folder, and mark all of its files (you can do this using the Select All menu option in the system Edit menu).
3. Drag this group of marked files into the exe folder which is now inside the phylip folder.
4. Now do the same for exe.2 (mark the files and drag them into but that is where these files need to be put. Do the following:
   1. Move the exe folder inside the phylip folder.
   2. Open the exe.1 folder, and mark all of its files (you can do this using the Select All menu option in the system Edit menu).
   3. Drag this group of marked files into the exe folder which is now inside the phylip folder.
   4. Now do the same for exe.2 (mark the files and drag them into exe).
   5. And do the same for exe.3 (mark the files and drag them into exe).
   6. You can now discard the folders exe.1, exe.2 and exe.3 (if any). If you have four folders named phylip3.65.0.sit, exe.1.sit, exe.2.sit, and exe.3.sit on your desktop, these can be discarded too.
   7. The phylip3.65 folder can now be moved to wherever you want it to be.

    

   Linux (using the Red Hat RPM package)

   (This is not yet available but is coming soon)

   A set of executables for Intel-compatible Linux systems is available, packaged in the Red Hat RPM system. If your Linux system can cope with an RPM package, then PHYLIP can be installed in the usual way: you must have super-user (root) access (or get your system manager to do this installation). Put the package in a folder and type the command:

   rpm -ivh phylip3.66.i386.rpm

   This will install PHYLIP in /usr/local/phylip with the executables and font files in /usr/local/bin.

   Linux and Unix

   If the Red Hat RPM package installation is not possible on your Linux system, or if you have another flavor of Unix, you can easily install PHYLIP and compile it yourself, provided that you have a C compiler on your system. (On some Linux systems and in recent versions of Mac OS X the C compiler is not installed by default, and you may have to make sure that it is installed).

   The archive for Linux or Unix systems is just the Documentation and Sources archive. You can extract the files from the archive by putting it into a folder by itself, getting into that folder, and giving the command
   

   gunzip phylip-3.67.tar.gz

   This uncompresses the archive so that it will now be bigger and be called phylip-3.67.tar. Now it is a "tar archive".

   Now just issue the command
   

   tar xvf phylip-3.67.tar

   The archive will be extracted and a phylip3.67 folder created that contains within it three folders, doc, exe, and src, as well as a web page phylip.html. You should start by reading that web page. It contains links to the documentation web pages, including the main documentation web page main.html.

   To make executables, use your C compiler. It is probably as simple as going into the src directory and typing the command
   

       make install
   

   which will cause the programs to be compiled and the executables and font files installed in the exe directory. If there are problems with the compilation, read the relevant sections of main.html and also the beginning of the Makefile.

    

   Reading the documentation

   The main folder contains a web page, phylip.html. You should start by reading it (either by clicking on it to activate your browser, or calling it to the attention of your browser in some other way such as drag-and-drop). It contains links to the documentation web pages, including the main documention page main.html, which you should read.

    

   Executables available from others

   Executables packages are also available from others. For the moment, these are for earlier versions of PHYLIP (such as 3.57c and 3.6b). They include executables for Red Hat Linux, Debian Linux, NetBSD Unix for Intel-compatible processors, and FreeBSD Unix. For links see our downloads page.
