[Fix Package]: assimp v6.0.5 编译失败：找不到 unzip.h

[githubnotebooks]

环境信息

• OS: Arch Linux (全新安装)
• xmake 版本: v3.0.9+20260519

问题描述

安装 assimp v6.0.5 时编译失败，报错找不到 unzip.h。

错误信息

/home/someone/.xmake/cache/packages/2607/a/assimp/v6.0.5/source/code/Common/ZipArchiveIOSystem.cpp:57:14: fatal error: unzip.h：没有那个文件或目录
   57 | #    include <unzip.h>
      |              ^~~~~~~~~
compilation terminated.

调查发现

1. 系统已有 minizip：

• /usr/include/minizip/unzip.h 存在
• /usr/lib/pkgconfig/minizip.pc 存在
• pkg-config --cflags minizip 没有输出（因为 Cflags 指向 /usr/include 默认路径）
• 所以代码中要使用 unzip.h，应该包含头文件 #include <minizip/unzip.h>，但 assimp 报错显示的是 include <unzip.h>，所以接下来检查 assimp 源码。

2. assimp 代码逻辑：

#ifdef ASSIMP_USE_HUNTER
#    include <minizip/unzip.h>
#else
#    include <unzip.h>
#endif
// 看来需要定义 ASSIMP_USE_HUNTER 才能使用 <minizip/unzip.h>

是不是 xmake 打包时没有添加 ASSIMP_USE_HUNTER？xmake 处理依赖的顺序是什么？是通过 xrepo 安装 minizip 还是使用系统的 minizip？我看到 xmake-repo 有 arch 的 CI 流程，为啥之前没有测试出来？是 arch 的 minizip.pc 配置变化了么？

Title: assimp v6.0.5 compilation failed: unzip.h not found

Environment information

• OS: Arch Linux (fresh install)
• xmake version: v3.0.9+20260519

Problem description

When installing assimp v6.0.5, compilation failed and an error was reported that unzip.h could not be found.

Error message

/home/someone/.xmake/cache/packages/2607/a/assimp/v6.0.5/source/code/Common/ZipArchiveIOSystem.cpp:57:14: fatal error: unzip.h: No such file or directory
   57 | # include <unzip.h>
      | ^~~~~~~~~
compilation terminated.

Investigation Discovery

1. The system already has minizip:

• /usr/include/minizip/unzip.h exists
• /usr/lib/pkgconfig/minizip.pc exists
• pkg-config --cflags minizip has no output (because Cflags points to the /usr/include default path)
• So to use unzip.h in the code, the header file #include <minizip/unzip.h> should be included, but the assimp error message shows include <unzip.h>, so check the assimp source code next.

2. assimp code logic:

#ifdef ASSIMP_USE_HUNTER
# include <minizip/unzip.h>
#else
# include <unzip.h>
#endif
// It seems that ASSIMP_USE_HUNTER needs to be defined to use <minizip/unzip.h>

Did xmake not add ASSIMP_USE_HUNTER when packaging? What is the order in which xmake processes dependencies? Do you install minizip through xrepo or use the system's minizip? I saw that xmake-repo has a CI process for arch. Why hasn’t it been tested before? Has the configuration of arch’s minizip.pc changed?
