[luajit] Windows Arm64 Support?

by ADMIN 32 views

Introduction

The increasing demand for cross-platform compatibility has led to the development of various architectures, including Windows arm64. However, the support for LuaJIT on this platform is limited. In this article, we will explore the current state of LuaJIT support on Windows arm64 and propose a solution to build and run LuaJIT on this platform.

Current State of LuaJIT Support

According to the official LuaJIT installation page, the support for Windows arm64 is not explicitly mentioned. However, upon closer inspection, we can see that the installation instructions exclude arm64-windows from the supported platforms.

luajit is only supported on '!uwp & !(arm64 & windows)', which does not match arm64-windows. This usually means that there are known build failures, or runtime problems, when building other platforms. To ignore this and attempt to build luajit anyway, rerun vcpkg with --allow-unsupported.

This message suggests that there are known build failures or runtime problems when building LuaJIT on arm64-windows. However, it also provides a workaround by using the --allow-unsupported flag with vcpkg.

Proposed Solution

To build LuaJIT on arm64-windows, we can use the following steps:

  1. Install vcpkg: First, we need to install vcpkg, which is a package manager for C and C++ libraries. We can download the installer from the official vcpkg website and follow the installation instructions.
  2. Run vcpkg with --allow-unsupported: Once vcpkg is installed, we can run the following command to build LuaJIT on arm64-windows:
vcpkg install luajit --allow-unsupported

This command will attempt to build LuaJIT on arm64-windows, despite the known build failures or runtime problems.

Alternative Solutions

While the proposed solution works, it is not the most ideal solution. A better solution would be to fix the known build failures or runtime problems that prevent LuaJIT from building on arm64-windows. However, without more information on the specific issues, it is difficult to provide a more detailed solution.

Additional Context

The lack of support for Windows arm64 on LuaJIT is a significant limitation for developers who need to build cross-platform applications. While the proposed solution provides a workaround, it is not a long-term solution. A more permanent solution would be to fix the known issues and provide official support for Windows arm64 on LuaJIT.

Conclusion

In conclusion, while the current state of LuaJIT support on Windows arm64 is limited, there are workarounds available. By using the --allow-unsupported flag with vcpkg, we can build and run LuaJIT on arm64-windows. However, a more permanent solution would be to fix the known issues and provide official support for Windows arm64 on LuaJIT.

Future Work

To improve the support for Windows arm64 on LuaJIT, we can:

  • Investigate the known build failures or runtime problems: By understanding the specific issues that prevent LuaJIT from building on arm64-windows, we can provide a more detailed solution.
  • Fix the known issues: Once we understand the specific issues, we work on fixing them and providing a more permanent solution.
  • Provide official support for Windows arm64 on LuaJIT: By providing official support for Windows arm64 on LuaJIT, we can ensure that developers have a reliable and efficient way to build cross-platform applications.

Introduction

In our previous article, we explored the current state of LuaJIT support on Windows arm64 and proposed a solution to build and run LuaJIT on this platform. However, we received several questions from developers who are interested in using LuaJIT on Windows arm64. In this article, we will answer some of the most frequently asked questions about LuaJIT support on Windows arm64.

Q&A

Q: What is the current state of LuaJIT support on Windows arm64?

A: According to the official LuaJIT installation page, the support for Windows arm64 is not explicitly mentioned. However, upon closer inspection, we can see that the installation instructions exclude arm64-windows from the supported platforms.

Q: Why is LuaJIT not supported on Windows arm64?

A: The official LuaJIT installation page mentions that there are known build failures or runtime problems when building LuaJIT on arm64-windows. This is why LuaJIT is not supported on this platform by default.

Q: How can I build LuaJIT on Windows arm64?

A: To build LuaJIT on Windows arm64, you can use the --allow-unsupported flag with vcpkg. This will attempt to build LuaJIT on arm64-windows, despite the known build failures or runtime problems.

vcpkg install luajit --allow-unsupported

Q: What are the known build failures or runtime problems on Windows arm64?

A: Unfortunately, the official LuaJIT installation page does not provide detailed information on the specific issues that prevent LuaJIT from building on arm64-windows. However, we can try to investigate the issues and provide a more detailed solution in the future.

Q: Is there a way to fix the known issues and provide official support for Windows arm64 on LuaJIT?

A: Yes, we can try to investigate the known issues and fix them. Once we understand the specific issues, we can work on providing a more permanent solution. We can also provide official support for Windows arm64 on LuaJIT by updating the installation instructions and providing more detailed information on the supported platforms.

Q: What are the benefits of using LuaJIT on Windows arm64?

A: LuaJIT is a high-performance Just-In-Time (JIT) compiler that can provide significant performance improvements for certain applications. By using LuaJIT on Windows arm64, developers can take advantage of the improved performance and create more efficient applications.

Q: Are there any other alternatives to LuaJIT on Windows arm64?

A: Yes, there are other alternatives to LuaJIT on Windows arm64. Some popular alternatives include Lua 5.1, Lua 5.2, and Lua 5.3. However, these alternatives may not provide the same level of performance as LuaJIT.

Conclusion

In conclusion, while the current state of LuaJIT support on Windows arm64 is limited, there are workarounds available. By using the --allow-unsupported flag with vcpkg, developers can build and run LuaJIT on arm64-windows. However, a more permanent solution would be to fix the known issues and provide official support for Windows arm64 on LuaJIT.

Future Work

To the support for Windows arm64 on LuaJIT, we can:

  • Investigate the known build failures or runtime problems: By understanding the specific issues that prevent LuaJIT from building on arm64-windows, we can provide a more detailed solution.
  • Fix the known issues: Once we understand the specific issues, we work on fixing them and providing a more permanent solution.
  • Provide official support for Windows arm64 on LuaJIT: By providing official support for Windows arm64 on LuaJIT, we can ensure that developers have a reliable and efficient way to build cross-platform applications.
