How to install UWIN
UWIN binaries are available in 3 packages namely - the Base package, Development package, and a few other Add-on packages.
The Base package consists of the UWIN runtime libraries, shells, utilities, daemons and services. It provides a virtual UNIX environment on Windows. Install only the base package if all you need is a set of UNIX command line tools.
The Development package adds application development support on UWIN. It consists of header files, libraries and development utilities like cc, make, rcs, etc. It can be used to build UWIN applications and/or to build native applications. Install this package along with the base package if you wish to develop applications using UWIN.
The Add-on packages include the X11 client applications and X11 server, the libraries needed to build X11 applications, Perl 5.8, fonts, and
UWIN doesn't offer binary level compatibility with UNIX. However, you can take the source code of a UNIX application, compile it in UWIN, and run it in Windows.
You can download the latest packages of UWIN at the AT&T Research website.
The actual download process is a bit tedious. However, if you persist you can successfully download, install, and run UWIN in Windows.
