Missing symbols when linking statically on macOS: SecRandomCopyBytes, _compression_stream_init

[yay]

I'm trying to link statically into an Odin executable, building minizip-ng with the following flags:

/Users/vitaly/projects/minizip-ng $ cmake -S . -B build -D MZ_BUILD_TESTS=ON -D MZ_COMPAT=OFF -D MZ_ZLIB=ON -D MZ_BZIP2=OFF -D MZ_LZMA=OFF -D MZ_ZSTD=OFF -D MZ_FETCH_LIBS=ON -D MZ_FORCE_FETCH_LIBS=ON -D MZ_PKCRYPT=ON -D MZ_WZAES=OFF -D MZ_OPENSSL=OFF -D MZ_LIBBSD=ON -D MZ_ICONV=OFF -D MZ_COMPRESS_ONLY=OFF -D MZ_DECOMPRESS_ONLY=ON -D MZ_FILE32_API=OFF -D MZ_BUILD_UNIT_TESTS=OFF -D MZ_BUILD_FUZZ_TESTS=OFF -D MZ_CODE_COVERAGE=OFF

but building the target Odin executable I get the following errors:

Undefined symbols for architecture arm64:
  "_SecRandomCopyBytes", referenced from:
      _mz_crypt_rand in libminizip-ng.a[13](mz_crypt_apple.c.o)

ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

On Windows, I am able to use minizip-ng with no issues, and don't run into _mz_stream_libcomp errors. I also realize _SecRandomCopyBytes and _kSecRandomDefault are macOS specific, but don't know why I'm getting these errors on a mac.

I've tried various combination of build flags, but I still get at least these 5 symbol errors. The only thing I need minizip-ng to do is to unzip unencrypted archives. Am I missing something?

You need to link to several frameworks on Apple. CoreFoundation, Security https://github.com/zlib-ng/minizip-ng/blob/fe5fedc365f7824ada0cf9a84fb79b30d5fc97a8/CMakeLists.txt#L474C16-L491C39

@Nekto89 That worked, thanks! But I'm still seeing the remaining three:

Undefined symbols for architecture arm64:
  "_compression_stream_destroy", referenced from:
      _mz_stream_libcomp_close in libminizip-ng.a[10](mz_strm_libcomp.c.o)

      _mz_stream_libcomp_read in libminizip-ng.a[10](mz_strm_libcomp.c.o)
ld: symbol(s) not found for architecture arm64

Any thoughts on how to fix these?

Not sure I understand. I already use MZ_LIBCOMP flag:

-- The following features have been enabled:

 * MZ_LIBCOMP, Enables Apple compression

Should I add something else to the cmake -S . -B build flags?

[yay]

Ah, got it, https://github.com/zlib-ng/minizip-ng/issues/478 MZ_LIBCOMP actually had to be disabled in my case. @Nekto89 Thanks a lot for the help!
