3. About Wine Started 1993 300 Developers from around the world
Free Implementation of the Windows API
LGPL license
Maintainer: Alexandre Julliard of CodeWeavers
Key Benefits:
Wine loader, runs Windows Binaries
WineLib, Ports Windows source

4. Wine Benefits – Binary Loader
Runs existing Windows executables
Load Windows DLLs and components for use under Linux
Runs at full speed (no machine emulation unlike VMWare / Win4Lin / Plex86)
Runs in user space (no kernel modules)
Integrates with Linux Window Manager
No Windows License or installation required

5. Wine Benefits - WineLib
Recompile existing C/C++ code to create native Linux executables
Flexible: mix and match DLLS, OCXs, and SO.
Programmers maintain one code base
Companies can continue to leverage Windows development expertise
Free, as in free beer (no run time license like Mainsoft/Bristol)
Free, as in free speech (source code available, independent of Microsoft)

6. Windows Architecture Windows Executable File (.EXE)
Application Libraries (DLLs)
Windows DLLs (e.g. Kernel, User, GDI)
Windows Low-level Drivers

9. Wine Challenges Developing Wine is HARD:
Huge Scope
Incomplete Specifications
Steep learning curve
Requires senior developers with knowledge of Windows, Linux, and X internals, and a love for debugging.
The Trap: Because it’s easy to use native DLLs, many Wine developers do
While single applications can be made to run well, most applications run poorly

10. What is CrossOver?
A line of products: CrossOver Plugin, CrossOver Office, Server Edition
Based on a customized version of Wine
Worked on by many of the best minds in Wine development (Alexandre Julliard…)
Mixed license (LGPL and proprietary)
Changes to Wine returned to Wine

11. CrossOver benefits Ease of installation and use Applications that work
Support if something goes wrong
Integration with the desktop
Server Edition
The benefits of thin clients without the price
Support for non Linux Unixes (e.g. Solaris)

12. What is Supported? Microsoft Office 2000 Microsoft Office 97
Word, Excel, Power Point, Outlook, IE, Visio
Microsoft Office 97
Word, Excel, Power Point
Lotus Notes 5.x
Quicken 2002

13. Future of CrossOver
Better international and multi-byte support, XIM input methods
Expanding the range of applications:
Access, Front Page
