Original Summary

Dependency-free POSIX compatibility layer and build environment for UEFI.<p><a href="https:&#x2F;&#x2F;gitlab.com&#x2F;bztsrc&#x2F;posix-uefi" rel="nofollow">https:&#x2F;&#x2F;gitlab.com&#x2F;bztsrc&#x2F;posix-uefi</a><p>Its goal is twofold: provides the usual libc API for EFI applications and an SDK on POSIX systems to create such EFI applications with a build system that works with CLang and gcc as well.<p>Its API is nowhere near complete as GNU-EFI&#x27;s or EDKII&#x27;s, so it provides seamless integration with those headers to make the API expandable. It is also not a fully POSIX standard compatible libc, it&#x27;s just a wrapper around the firmware provided features with some minimal additions, but provides enough for everyday use cases. As being minimal, it&#x27;s extremely small (~132K of source only) and because it&#x27;s dependency-free, it&#x27;s easy to integrate into any project.<p>The repo contains lots of examples too, from a simple &quot;Hello World&quot; to more complex ones like displaying a PNG splash screen or loading a &quot;kernel&quot; in ELF format.<p>POSIX-UEFI is 100% AI-free, and has been tested on almost every VMs and on lots of real hardware by volunteers over the years. It is feature complete, stable and considered bug-free by now (big thanks to contributors), although some workarounds for buggy firmware might be added in the future.

中文标题： Show HN：POSIX-UEFI

Show HN介绍POSIX-UEFI：一个无依赖的POSIX兼容层与构建环境，为UEFI应用提供常用libc API，并可在POSIX系统上配合CLang和gcc构建此类EFI应用。其API尚不完整，可与GNU-EFI或EDKII头文件无缝集成以扩展，体积很小（仅约132K源码）且无需依赖，便于集成。仓库含大量示例，从Hello World到显示PNG启动画面、加载ELF格式“内核”。该项目100%无AI参与，已在众多虚拟机和大量真实硬件上由志愿者测试，功能完整、稳定且现被认为无缺陷。
