在 Mac OS 10.16 (Big Sur) 中通过 homebrew 构建 libzip 时找不到 libz.dylib

Question

通过自制程序（Mac OS 10.16）构建libzip时，它会抱怨

make[2]: *** No rule to make target /usr/lib/libz.dylib', needed by `lib/libzip.5.3.dylib'.  Stop.

，但我有/usr/lib/libz.dylib作为软链接，真正的lib（libz.1.dylib）丢失了。

那么我该如何解决这个问题？

   brew reinstall libzip

2. 我的 /usr/lib 中只有到

   libz.1.dylib 

   的软链接

~$ ls -l /usr/lib/libz.*
lrwxr-xr-x  1 root  wheel  12 Jan  1  2020 /usr/lib/libz.1.1.3.dylib -> libz.1.dylib                                                                                        lrwxr-xr-x  1 root  wheel  12 Jan  1  2020 /usr/lib/libz.1.2.11.dylib -> libz.1.dylib
lrwxr-xr-x  1 root  wheel  12 Jan  1  2020 /usr/lib/libz.1.2.5.dylib -> libz.1.dylib

lrwxr-xr-x  1 root  wheel  12 Jan  1  2020 /usr/lib/libz.dylib -> libz.1.dylib

3. libz.1.dylib

   不见了。

~$ sudo find / -name "libz.1.dylib"
/usr/local/homebrew/Cellar/zlib/1.2.11/lib/libz.1.dylib
/System/Volumes/Data/usr/local/homebrew/Cellar/zlib/1.2.11/lib/libz.1.dylib

...
(lib.1.dylib from CoreSimulator)

Answer 1

感谢 Stefano Mtangoo's 评论和 answer，我通过手动将 cmake 参数添加到 fomula 文件来修复此问题。

1. 从 homebrew 安装 libzip 的依赖项。

brew install zlib bzip2

2. 将自制库添加到 CMake 定义中。

brew edit libzip.rb

将 L22 更改为

    system "cmake", ".", *std_cmake_args

到

    system "cmake", ".", *std_cmake_args, "-DZLIB_LIBRARY_RELEASE=/usr/local/homebrew/opt/zlib/lib/libz.dylib","-DBZIP2_LIBRARY_RELEASE=/usr/local/homebrew/opt/bzip2/lib/libbz2.a", "(... rest of the args.."

（/usr/local/homebrew是我的自制程序前缀。）

3. 重新安装 libzip。

brew reinstall --verbose libzip

备注：

您可以使用

brew reinstall --verbose libzip --interactive

来防止删除工作目录并检查源代码。

然后使用 grep 查找损坏的 cmake 定义并重新运行 *cmake ... * 来测试设置。

我尝试过设置PATH/LD_LIBRARY_PATH，但它不起作用。
