16 <!-- general description of wine, what does it do? -->
17 <para>
18 Many people have faced the frustration of owning software that
19 won't run on their computer. With the recent popularity of
20 <ulink url="http://www.tldp.org/FAQ/Linux-FAQ/index.html">
21 Linux</ulink>, this is happening more and more often because
22 of differing operating systems. Your Windows software won't
23 run on Linux, and your Linux software won't run in Windows.
24 </para>
25 <para>
26 A common solution to this problem is to install both operating
27 systems on the same computer, as a <quote>dual boot</quote>
28 system. If you want to write a document in MS Word, you can
29 boot up in Windows; if you want to run the GnuCash, the GNOME
30 financial application, you can shut down your Windows session
31 and reboot into Linux. The problem with this is that you
32 can't do both at the same time. Each time you switch back and
33 forth between MS Word and GnuCash, you have to reboot again.
34 This can get tiresome quickly.
35 </para>
36 <para>
37 Life would be so much easier if you could run all your
38 applications on the same system, regardless of whether they
39 are written for Windows or for Linux. On Windows, this isn't
40 really possible, yet.
41 <footnote>
42 <para>
43 Technically, if you have two networked computers, one
44 running Windows and the other running Linux, and if you
45 have some sort of X server software running on the Windows
46 system, you can export Linux applications onto the Windows
47 system. A free X server is available at
48 <ulink url="http://xfree86.cygwin.com/">http://xfree86.cygwin.com/</ulink>.
49 However, this doesn't solve the problem if you only own
50 one computer system.
51 </para>
52 </footnote>
53 However, Wine makes it possible to run native Windows
54 applications alongside native Linux applications on any Unix-like
55 system. You can share desktop space between MS Word and GnuCash,
56 overlapping their windows, iconizing them, and even running them
57 from the same launcher.

62 <title>Emulation versus Native Linking</title>
63 <!-- emulator vs. Winelib -->
64 <para>
65 Wine is a UNIX implementation of the win32 libraries,
66 written from scratch by hundreds of volunteer developers and
67 released under an open source license. Anyone can download
68 and read through the source code, and fix bugs that arise.
69 The Wine community is full of richly talented programmers
70 who have spent thousands of hours of personal time on
71 improving Wine so that it works well with the win32
72 <firstterm>Applications Programming Interface</firstterm>
73 (API), and keeps pace with new developments from Microsoft.
74 </para>
75 <para>
76 Wine can run applications in two discrete ways: as
77 pre-compiled Windows binaries, or as natively compiled
78 <ulink url="http://www.xfree86.org/#whatis">X11 (X-Window
79 System)</ulink> applications. The former method uses
80 emulation to connect a Windows application to the Wine
81 libraries. You can run your Windows application directly
82 with the emulator, by installing through Wine or by simply
83 copying the Windows executables onto your Linux system.
84 </para>
85 <para>
86 The other way to run Windows applications with Wine requires
87 that you have the source code for the application. Instead
88 of compiling it with native Windows compilers, you can
89 compile it with a native Linux compiler --
90 <command>gcc</command> for example -- and link in the Wine
91 Libraries as you would with any other native UNIX
92 application. These natively linked applications are
93 referred to as Winelib applications.
94 </para>
95 <para>
96 The Wine Users Guide will focus on running precompiled
97 Windows applications using the Wine emulator.
98 The Winelib Users Guide will cover Winelib
99 applications.

132 Wine can be pretty intimidating at first. The Wine
133 distribution consists of over two thousand files and half a
134 million lines of source code

140 and is probably one of the steepest learning curves in the
141 open source world. This chapter will give you a crash course
142 in the important topics you need to know to get started with
143 running Wine applications.
