The already-compiled executables available are

• Windows executables, which are 32 bit executables that will work on Windows95, Windows98, Windows NT, Windows 2000, Windows me, and Windows xp.
• Macintosh MacOS X executables for PowerMac and Intel MacOS X systems. We distribute "universal binaries" that work on both platforms (basically they are a pair of binaries set up so that the appropriate one will run). These use the native MacOS X Aqua windowing system for the character-based menus and for the graphics windows for the tree-drawing programs. The programs are activated by clicking on their icons. Links are also provided in the same folder that enable the programs to be run by typing their names.
• Macintosh MacOS executables for Apple Macintosh systems running MacOS 8 or MacOS 9 (we don't know whether they will work on MacOS 7). They will not work on pre-PowerMac 680x0 Macintosh systems.
  These are not yet available for version 3.66.
• Linux executables for Intel-compatible processors, packaged in the Red Hat RPM package system. This is not yet available for version 3.66, though it is easy to prepare your own Linux executables using the source code.

Each is available as one or more self-extracting archives. That means that they are large files that contain in compressed form the various executables for that system, plus a self-extraction program. When you execute the self-extracting archive as if it were a program, it unpacks itself into many different files and puts them on your hard disk. The Mac OS X distribution is as a Disk Image, and after that is unpacked you have to copy the contents out to another folder before using them.

If you get the executables for any of these types of machines, make sure you also get the documentation files. These are packaged with the source code in one of the self-extracting archives.

For many Unix or Unix-compatible systems, executables are not necessary. Provided that your Unix system has a C compiler, you can easily compile the source code yourself. Put the source code in a directory and type "make all", and executables should be produced.

Note -- for the moment, some of these executables packages are not yet updated to the 3.66 release. Some are earlier, as indicated.

Red Hat Linux RPMs

Luc Ducazu, of Merelbeke, Belgium, has put together Red Hat Linux RPM packages of version 3.61. There is one of executables compiled with the Gnu GCC compiler, one of executables compiled with the Intel ICC compiler, and one of documentation and sources. They can be downloaded from their page at the Biolinux web site. These can be installed on versions of Linux that have a package management system that handles RPMs. One set is for RedHat 9, another for the Fedora Core 1 and Fedora Core 2 distributions which are the successors for the low-end Red Hat distributions, and another is for Suse Linux 9.1.

Debian linux executables

Andreas Tille and Stephane Bortzmeyer have compiled and made available a set of PHYLIP 3.65 executables and older PHYLIP 3.61 executables for Debian Linux. These are in the "unstable" section of Debian packages and may be downloaded for free ("free in the sense of free beer") from its page on the Debian web site at http://packages.debian.org/unstable/science/phylip. or from various Debian mirror sites. Of course, one can also install the source code (see under Unix above) and compile it yourself.

Executables for FreeBSD

A PHYLIP 3.65 package for FreeBSD Unix is available, thanks to David Bader and others. It is located at the BSD PHYLIP package web page at http://www.freebsd.org/cgi/cvsweb.cgi/ports/biology/phylip/.
