feat(pkg): compat.opencv5 5.0.0 — 全源码直编 + build.mcpp 消费端合成(新形态)#76
Merged
Conversation
OpenCV 5.0.0 (core/imgproc/imgcodecs/highgui/videoio + flann/geometry 闭包),
mcpp 直编 457 TU(含 27 NASM .asm),SIMD runtime dispatch 保留(per-ISA glob
flags)。小 config 快照(59KB/171 文件)内联;大生成物(字体 hex 头、OpenCL
kernel 内嵌、转发 TU 层)由包内嵌 build.mcpp 在消费端合成 —— CMake 逻辑逐字节
忠实移植(与参考构建 diff 8/8 IDENTICAL)。官方 tarball + CN 镜像
(mcpp-res/opencv@5.0.0,sha256 双端核验)。
转发 TU 层同时解决 mcpp#233(对象路径折叠冲突)、libjpeg-turbo BITS_IN_JSAMPLE
同源三编、mcpp#234(defines 含空格)。端到端验证(mcpp 0.0.96):零 override
消费工程冷构建 33s 全绿;workspace 成员 tests/examples/opencv5 (cfg(linux))。
工具链:tools/compat-opencv5/{fetch_upstream.sh,gen_config.sh,gen_descriptor.py,
build_mcpp_template.cpp};gen_descriptor 对全部参考编译命令做精确重构断言。

概要
新增
compat.opencv55.0.0 —— OpenCV 5 全源码直编包,并确立第五种包形态:全源码直编 +build.mcpp消费端合成。构建期零 CMake:mcpp 直编 457 TU(含 27 个 libjpeg-turbo NASM
.asm),SIMD runtime dispatch 完整保留(per-ISA glob flags),冷构建 ~33s/32 核。为什么是新形态
OpenCV 构建期生成物达 17MB(内置字体 hex 头 + OpenCL kernel 内嵌 + 逐 TU 转发 stub),无法走 compat.ffmpeg 的纯内联路线。本包:
build.mcpp(0.0.95 依赖包 build.mcpp 执行 +mcpp:generated=+ OUT_DIR 契约的首个 index 实战)在构建时从官方 tarball 合成字体头(blob2hdr)、OpenCL kernel 内嵌(cl2cpp + MD5)、457 个转发 TU —— 全部为 CMake 逻辑逐字节忠实移植(与参考构建 diff 8/8 IDENTICAL)转发 TU 层一石三鸟:mcpp#233(对象路径按父目录名折叠,
modules/*/src/同名源冲突)、libjpeg-turbo BITS_IN_JSAMPLE=8/12/16 同源三编、mcpp#234(defines 含空格被拆散 → 注入 stub 顶部#define)。#233/#234 修复后可退役。Profile(linux-x86_64,v0.1)
BUILD_LIST=core,imgproc,imgcodecs,highgui,videoio(+ flann/geometry 闭包);hermetic(外部探测全 OFF、vendored zlib/libpng/libjpeg-turbo);headless highgui;V4L2 videoio;WITH_UNIFONT=OFF(configure 期额外下载,破坏单源封闭;将来 feature)。language = "c++23"(上游 c++17;457 TU 已在 gcc16 c++23 下全绿)。镜像与验证
