Wine Ported to OpenBSD

You can now run many 64-bit Windows applications directly on OpenBSD without a virtual machine.

Thomas Frohwein has submitted a port of the Wine emulation software to OpenBSD. This development enables the execution of 64-bit Windows applications on OpenBSD, a feat previously unsupported. The port's success hinged on addressing the %gs base register issue through software emulation, a solution pioneered by Andrii and Fabien. Initial testing with various 64-bit Windows software, including demanding applications like the recent Witcher 3 remaster, has shown promising results. However, the port currently does not support 32-bit Windows applications due to the non-functional WoW64 subsystem. Built-in tests are also disabled pending further development to allow for X server access and resolve hanging issues. Users are advised to run Wine on OpenBSD with caution, ideally on a separate, non-privileged user account.

The successful porting of Wine to OpenBSD signifies a growing interest in running Windows software on alternative operating systems, particularly for gaming and productivity. This development could expand the user base for OpenBSD by making it a more viable option for those who rely on specific Windows applications, bridging a significant gap in its software ecosystem. The focus on 64-bit applications also aligns with the industry-wide shift towards 64-bit architecture, suggesting a forward-looking approach to compatibility.

While this port offers new possibilities, the exclusion of 32-bit application support and the temporary disabling of built-in tests highlight areas for future improvement. The team's efforts to explore security enhancements like `unveil(2)` are crucial for making Wine on OpenBSD a more robust and secure solution. Further development in these areas will determine the port's long-term stability and broad usability for the OpenBSD community.
