Appendix E. Squid on Windows

Squid has been designed to run on Unix, but you can also get it to run on Microsoft Windows. Perhaps the easiest way is to use Red Hat’s Cygwin emulation layer.

This is a version of the source code that has been modified to compile under a native Windows C compiler.

Cygwin

Cygwin is a Unix emulation package for Microsoft Windows. It provides an environment that allows you to build and run software primarily designed for Unix. You can also download and install a number of precompiled binary packages, including Squid.

When writing this appendix, I installed Cygwin Version 1.3.21 on Windows 2000.

After running Cygwin Setup, you’ll have the base environment with a number of standard Unix tools. You might want to spend a little time playing with it to see how it works. Once you’re comfortable with the Cygwin environment, decide if you’d like to use the precompiled package or compile Squid from its source. ...
