Introduction
What is Wine?

Windows and Linux
Many people have faced the frustration of owning software that
won't run on their computer. With the recent popularity of
Linux, this is happening more and more often because of
differing operating systems. Your Windows software won't run
on Linux, and your Linux software won't run in Windows.
A common solution to this problem is to install both operating
systems on the same computer, as a dual boot
system. If you want to write a document in MS Word, you can
boot up in Windows; if you want to run the GnuCash, the GNOME
financial application, you can shut down your Windows session
and reboot into Linux. The problem with this is that you
can't do both at the same time. Each time you switch back and
forth between MS Word and GnuCash, you have to reboot again.
This can get tiresome quickly.
Life would be so much easier if you could run all your
applications on the same system, regardless of whether they
are written for Windows or for Linux. On Windows, this isn't
really possible.
Technically, if you have two networked computers, one
running Windows and the other running Linux, and if you
have some sort of X server software running on the Windows
system, you can export Linux applications onto the Windows
system. A free X server is available at
http://xfree86.cygwin.com/.
However, this doesn't solve the problem if you only own
one computer system.
However, Wine makes it possible to run native Windows
applications alongside native Linux applications on a Linux
(or Solaris) system. You can share desktop space between MS
Word and GnuCash, overlapping their windows, iconizing them,
and even running them from the same launcher.
Emulation versus Native Linking
Wine is a UNIX implementation of the win32 libraries,
written from scratch by hundreds of volunteer developers and
released under an open source license. Anyone can download
and read through the source code, and fix bugs that arise.
The Wine community is full of richly talented programmers
who have spent thousands of hours of personal time on
improving Wine so that it works well with the win32
Applications Programming Interface
(API), and keeps pace with new developments from Microsoft.
Wine can run applications in two discrete ways: as
pre-compiled Windows binaries, or as natively compiled X11
(X Window System) applications. The former method uses
emulation to connect a Windows application to the Wine
libraries. You can run your Windows application directly
with the emulator, by installing through Wine or by simply
copying the Windows executables onto your Linux system.
The other way to run Windows applications with Wine requires
that you have the source code for the application. Instead
of compiling it with native Windows compilers, you can
compile it with a native Linux compiler --
gcc for example -- and link in the Wine
Libraries as you would with any other native UNIX
application. These natively linked applications are
referred to as Winelib applications.
The Wine Users Guide will focus on running precompiled
Windows applications using the Wine emulator.
The Winelib Users Guide will cover Winelib
applications.
Wine Requirements and Features
Written by &name-andreas-mohr; &email-andreas-mohr;
System requirements
In order to run Wine, you need the following:
a computer ;-) Wine: only PCs >= i386 are supported at
the moment. Winelib: other platforms might be
supported, but can be tricky.
a UNIX-like operating system such as Linux, *BSD,
Solaris x86
>= 16MB of RAM. Everything below is pretty much
unusable. >= 64 MB is needed for a "good" execution.
an X11 window system (XFree86 etc.). Wine is prepared
for other graphics display drivers, but writing
support is not too easy. The text console display
driver is nearly usable.
Wine capabilities
Now that you hopefully managed to fulfill the requirements
mentioned above, we tell you what Wine is able to do/support:
Support for executing DOS, Win 3.x and Win9x/NT/Win2000
programs (most of Win32's controls are supported)
Optional use of external vendor DLLs (e.g. original
Windows DLLs)
X11-based graphics display (remote display to any X
terminal possible), text mode console
Desktop-in-a-box or mixable windows
Pretty advanced DirectX support for games
Good support for sound, alternative input devices
Printing: supports native Win16 printer drivers,
Internal PostScript driver
Modems, serial devices are supported
Winsock TCP/IP networking
ASPI interface (SCSI) support for scanners, CD writers,
...
Unicode support, relatively advanced language support
Wine debugger and configurable trace logging messages
