This patch addresses template strictness errors in MySQL 8.4 serialization headers when compiled with modern Clang (version 17 or newer). The changes involve explicitly specifying template arguments for get_size and get_size_serializable methods, and adjusting lambda capture lists and decltype usage to conform to stricter C++20 rules. This is a critical correctness fix for building on macOS with up-to-date compilers.

This #ifdef __APPLE__ block correctly provides macOS-specific definitions for byte order conversion macros (htobe16, htole16, etc.) and mempcpy. These are essential for cross-platform compatibility, as macOS uses libkern/OSByteOrder.h and different function names compared to Linux's <endian.h> for these operations. This is a critical correctness fix for building on Apple platforms.

There was a problem hiding this comment.
Modifying update_ulong_var_if_set to use an intermediate unsigned long val for opt->get(cmd_opt)->getULong(val) and then assigning it to cur_val is a crucial correctness fix. The getULong method expects an unsigned long&, but cur_val is a uint64_t&. This ensures type compatibility and prevents potential undefined behavior or data loss on platforms where uint64_t and unsigned long might have different sizes.

The sed command to modify zutil.h is a targeted fix for a specific compilation issue related to fdopen on macOS. This ensures that the zlib component within the MySQL 8.4 connector builds correctly on Darwin.

Changing SSL_LDIR from lib64 to lib for Darwin is a necessary platform-specific adjustment. macOS typically installs libraries in /lib or /usr/local/lib, not /lib64.

Specifying -DWITH_SSL=$$(brew --prefix openssl@3) -DOPENSSL_ROOT_DIR=$$(brew --prefix openssl@3) for the MySQL 8.4 connector cmake command on Darwin is essential. This explicitly tells cmake where to find the Homebrew-installed OpenSSL 3, ensuring correct linking.

Enforcing -j1 (sequential build) for MySQL 8.4 connector on Darwin is a good practice if intermittent race conditions are observed during parallel builds. This prioritizes build reliability over speed for this specific dependency on macOS.

This conditional block correctly adjusts the search for OpenSSL library files (libssl.dylib, libcrypto.dylib, .a archives) for Darwin. This is essential for linking against OpenSSL on macOS, where dynamic libraries typically use the .dylib extension instead of .so.

The sed command uses an inline replacement to skip a runtime library check in the curl configure script. While this works on Darwin, it would be more maintainable to use a dedicated patch file similar to how other dependencies are handled, especially since this appears to be a workaround for a macOS-specific issue with dynamic library path checking. This would make the change more explicit and easier to understand.

In `@doc/BUILD-MACOS.md`:
- Around line 23-27: The docs hardcode the Homebrew prefix (/opt/homebrew) for
PATH, PKG_CONFIG_PATH, and OPENSSL_ROOT_DIR which breaks on Intel macs; update
the instructions in BUILD-MACOS.md to compute the prefix dynamically (use `brew
--prefix`) and interpolate that value for PATH, PKG_CONFIG_PATH and
OPENSSL_ROOT_DIR so the same snippet works on both Intel and Apple Silicon

cut -d'.' -f3for patch, which would fail to parse correctly if the patch component contains non-numeric suffixes.Consider normalizing the comparison approach, or stripping suffixes before comparison:

Use Homebrew prefix to avoid Intel/Apple path mismatch.
The guide targets both Intel and Apple Silicon, but hardcodes /opt/homebrew. On Intel, Homebrew usually lives in /usr/local. Suggest using brew --prefix to make this portable.

Homebrew prefix paths Apple Silicon Intel macOS /opt/homebrew /usr/local
💡 Result:
Short answer
- Default Homebrew prefixes:
- Apple Silicon (ARM/M1/M2/M3): /opt/homebrew. [1]
- Intel macOS (x86_64): /usr/local. [1][2]
Why it matters
- Prebuilt bottles (binary packages) are produced for the default prefix; installing outside it can force source builds or fail. [2]
- Using different prefixes lets ARM and Intel installs coexist (useful with Rosetta). [3]
Common commands
- Show the prefix Homebrew is using: brew --prefix. [1]
- Show which brew will run: which brew or command -v brew.
- Run ARM or Intel installer under a specific arch (Rosetta) if needed: arch -x86_64 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)". [1]
PATH / shell note
- After install the installer prints “Next steps” (you must add the /opt/homebrew or /usr/local paths to your shell PATH or run brew shellenv). Example for Apple Silicon: eval "$(brew shellenv)" or add export PATH="/opt/homebrew/bin:$PATH". [1]
If you see errors
- “Cannot install in Homebrew on ARM processor in Intel default prefix (/usr/local)” means you’re running ARM macOS but Homebrew is in the Intel prefix; reinstall or install a separate ARM Homebrew in /opt/homebrew. [4]
Sources
[1] Homebrew installation docs (default prefixes and installer behavior).
[2] Homebrew FAQ (why use the default prefix; bottles).
[3] Discussion/why /opt/homebrew was chosen (Apple StackExchange summary).
[4] Example error + community guidance (StackOverflow).
Document both Homebrew prefixes (Apple Silicon vs Intel).
The current snippet only shows the /opt/homebrew path used by Apple Silicon Macs. Intel Mac users would need /usr/local instead. Using brew --prefix in the documentation provides a portable solution that works across architectures.
