build-glibc.sh 在源码、打包名及配方多个位置依赖 x86_64/lib64。 +需要参数化，而不是只给 archs 加 aarch64。保留其 loader 默认搜索路径、 +ld.so.cache、ld.so.preload、安装前缀 relocation 与 locale/gconv 修补。 +2.44.3 是索引包版本；其上游源码版本、修订与补丁集合分别记录。 + +推荐 aarch64 布局为 `lib/ld-linux-aarch64.so.1`、`lib/*.so*`、 +`include/`，runtime export 为 `abi = linux-aarch64-glibc`， +`loader = lib/ld-linux-aarch64.so.1`，明确 `libdirs = {lib}`。 +这是本方案指定的布局，构建与包验收必须使其成立，不能当作上游归档布局。 +x86_64 的 lib64 布局继续有效。loader 文件名、核心库清单、配置/检查中的 +libdir、辅助程序启动路径均来自同一架构描述。 + +### 4.4 架构路由与兼容性 + +每个配方必须同时核对：archs、版本可用集合、每架构 URL/sha256、 +依赖坐标、解包目录、runtime exports、sysroot 配置与测试。单独扩大 +archs 会让旧版本也被误报可安装；20.1.7/22.1.8 的 aarch64 缺席应继续 +是具名不可用，而不是尝试下载不存在的旧 ARM64 资产。 + +优先复用现有 libxpkg 的实际架构注入和资源解析契约。在加载 package +表的时刻是否能可靠读取目标架构，需要在发布版 xlings、mcpp vendored +xlings 两个入口上实测。历史文档曾记录 os.arch stub；本地较新 +libxpkg 已有 `__xpkg_arch__` 注入，这只提供检查方向，不证明已发布 +客户端具有同样能力。涉及 arch 选择的 loader/ABI metadata 不能延迟到 +install 回调后才修改，因为 resolver 可能已读取 exports。 + +若现有客户端不足，优先使用现有按架构资源契约或明确架构包坐标， +保持公开 `llvm@23.1.3` 在解析层可达；需要客户端能力时声明最小版本。 +此处设为兼容性门，未验证前不假定两仓库改动足够，也不先开新的协议。 + +### 4.5 发布内容不可变 + +新增 ARM64 资产可以挂既有 23.1.3 release；不能重写已发布的 x86_64 +同名文件。新资源有三方相同 sha256：carve、GLOBAL 重下载、CN 重下载。 +每架构每格式各自钉摘要，不共用 x86 哈希。错误资产需要具名 revision +与新文件名；不依赖 GitCode 覆盖同名文件。 + +## 5. mcpp：宿主默认、目标能力与构建链 + +### 5.1 只为 aarch64 增加默认分支 + +新增 `kFirstRunLinuxAarch64 = llvm@23.1.3`，在 +`pins::host_default_toolchain` 中显式区分 x86_64、aarch64、其他 Linux。 +保留 `kFirstRunLinuxOther`，避免 riscv64 等没有载荷的宿主被改成 LLVM。 +首次安装、self env、建议安装消息与默认值文档读取同一钉点。 + +新的默认产生 aarch64-linux-gnu，不能从此前 musl 的持久 target 或 GCC +解析惯例继承而出现 `LLVM 默认 + musl target` 的隐式组合。冷 home 的 +双轴断言是验收门；已有记录不强迁，显式用户选择仍保持优先级。 + +### 5.2 将 native GNU 行从 planned 转为实测支持 + +在原生 ARM64 Linux 完成编译、链接和运行门后，把 +`aarch64-linux-gnu` 提升为 verified；推荐该行 pin 为 `llvm@23.1.3`， +其语义是原生 glibc 工具链约定，不是禁止其他可服务编译器的能力锁。 +sysroot 来源按现有 runtime binding 机制接入受管 glibc 与 UAPI 头。 +若增加 sysroot 坐标，必须确认该字段确实被现有 hosted GNU 路径消费， +不能只在表上填值就宣称引擎已支持。 + +验证 `host_can_serve`、planned gate、toolchain list、why、matrix 扫描 +和实际 build 一致。原生 host 能用的 GNU 行不意味着 x86_64 Linux、 +macOS、Windows 已有 aarch64 glibc cross sysroot；这些组合仍给明确 +的 refusal 或 graph-supplied 支持，不升级为 payload-served。 + +### 5.3 按宿主与版本公布可用性 + +移除 `available_toolchain_indexes` 对 Linux aarch64 的 LLVM 全族隐藏， +但仍隐藏没有载荷的其他架构。允许列出 LLVM 族后，旧发行版列表必须 +按实际平台资源过滤，不把 20.1.7/22.1.8 也当作 ARM64 可装版本。 +替换 `check_aarch64_llvm_deferral.sh` 的历史否定门为正向安装门： +当前 line 的资源存在、架构正确、可安装且可启动。其他 deferred 组合 +保留各自的理由，不删掉所有保护分支。 + +### 5.4 mcpp 自举与宿主工具跟随新默认 + +根 mcpp.toml 的 `[toolchain] default = gcc@16.1.0` 不会因 first-run +默认变化自行变成 LLVM。推荐使用已有 +`[target.aarch64-linux-gnu] toolchain = llvm@23.1.3`；当前实现会在无 +`--target` 时应用 host row，CLI 指定仍优先。不引入未经实现的 +`[toolchain.linux-aarch64]` 拼法。对 native build 实测匹配到 GNU host +row；专用 CI 另显式传入工具链与目标，记录两种入口的结果。 + +build.mcpp、path host tool、import std/std.compat 和单测均用这套宿主 +运行链验证；musl 静态发布继续走显式 aarch64-linux-musl。bootstrap +可以仍是静态发布二进制，不要求发布程序本身依赖新 glibc 才能启动。 + +### 5.5 ABI 与系统库边界 + +glibc C ABI 可用于链接 C 系统库；这不等于 libc++ 可直接消费所有 +libstdc++ C++ ABI 的预制包。继续使用现有 ABI tag 与 prebuilt 校验， +GCC → LLVM 后旧 BMI、标准库模块与链接产物必须失效。 +测试 C ABI 依赖、共享库、pack 后运行、异常跨模块与线程；不默认允许 +跨标准库传递 std::string/std::vector。 + +## 6. 把 #781 review 缺口纳入交付 + +| Review 问题 | Part 2 的具体处理 | 完成判据 | +|---|---|---| +| xcode-27 缺第

项尚有缺口：四个真实索引成员在 +原生 GNU 上通过，不能证明代表性库的 openkal 交叉路径。现有 +托管应用增加真实 `nlohmann.json@3.12.0` 模块和行为检查，复用 +既有构建与目标运行 job。四宿主记录实际 mcpp-index 提交，目标 +门同时检查 JSON 与线程成功行。原生门及正式 CN SubOS 使用实际 +索引 checkout

已成功，实际完成原有样例与线程应用的三个 +目标构建，验证第 17 节原生 Windows 路径规范化更正。该 job 使用 +新增 JSON 行为检查之前的线程源码，不替代本节新增库的最终 CI。 + +## 19. 2026-10-08 四宿主源码字节一致性更正 + +Windows job `113112389601` 的线程源码摘要为

+旧客户端补充试验确认验证作用域不能仅由私有存储目录推定。 +从共享项目目录启动会读取项目 `.xlings.json`；`-u` 表示激活， +`-g` 才表示全局作用域。正式 CN 验证显式采用 `-g` 安装公开 +mcpp 版本，本地冷目录脚本同样显式安装其 bwrap 后端。当前客户端 +`2026.10.8.1` 的实际帮助输出已确认这两项参数语义。 + +## 22.

A process that could not resolve `vkCreateInstance` - # from that DLL fails during image load and prints nothing at all. - # mcpp-index's own `vulkan-tests` member calls - # `vkEnumerateInstanceVersion` on the windows shards and passes. - # - # 2. Not an unparseable ICD manifest, though that WAS a real defect. - # `xim:mesa-lavapipe` wrote its rewritten `library_path` into the - # JSON string unescaped, so `C:\Users\...` carried `\U` and the - # loader's cJSON parser rejected the file -- an ICD it skips with no - # error. Fixed in openxlings/xim-pkgindex#781. With the fix the runner - # reads - # "library_path": "C:/Users/.../lib/vulkan_lvp.dll" - # and the manifest parses. The program still prints `render - # unavailable`. - # - # 3. Not a failed `LoadLibrary`. `vulkan_lvp.dll` imports only - # ADVAPI32, GDI32, KERNEL32, ntdll, ole32, SHELL32 and USER32, all of - # which any Windows has; the payload ships nothing else that could be - # missing. - # - # 4. Not the environment variable's vintage. Both `VK_DRIVER_FILES` and - # `VK_ICD_FILENAMES` were set, which covers loaders on either side of - # 1.3.234. - # - # What the loader itself said under `VK_LOADER_DEBUG=all`: - # - # INFO: Loader is running with elevated permissions. - # Environment variable VK_DRIVER_FILES will be ignored - # INFO: Loader is running with elevated permissions. - # Environment variable VK_ICD_FILENAMES will be ignored - # DRIVER: Found no registry files in - # HKEY_LOCAL_MACHINE\SOFTWARE\Khronos\Vulkan\Drivers - # ERROR | DRIVER: windows_read_data_files_in_registry: Registry lookup - # failed to get ICD manifest files. Possibly missing Vulkan driver? - # - # THAT IS THE WHOLE ANSWER, AND NO PACKAGE CHANGE REACHES IT. A GitHub - # Windows runner runs elevated, and the loader discards every driver-path - # environment variable when it is -- it will not let a path a - # non-administrator could write inject a driver into an elevated process. - # It then falls back to the registry, which has no ICD.
