Outline About the Speaker Overview of Wine Overview of CrossOver Future of CrossOver Demonstration

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

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

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)

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

Wine Architecture Windows Executable File (.EXE) Application Libraries (DLLs) [OPTIONAL] Windows DLLs Wine System Libraries Linux Low Level Drivers (glibc, x11drv)

Wine Scope DLLs Functions Windows1 540 14,786 Wine2 120 8,275 Used in MS Office34 24 445 Wine Coverage of MS Office4 24 445 1 Stock Windows 98 Installation 2 As of May 1, 2002 3 Static Linkage Only 4 Basic usage

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

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

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)

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 QuickTime, Windows Media Player, Shockwave, Trillian, more than 10 other plugins

Future of CrossOver Better international and multi-byte support, XIM input methods Expanding the range of applications: Access, Front Page Office 2002 / XP support Lotus Notes 4.x and 6.x support MS Project, QuickBooks, Photoshop, Lotus SmartSuite, etc.
