Compiling ProxySQL on macOS

This guide provides step-by-step instructions for compiling ProxySQL from source on macOS (Intel or Apple Silicon) using Homebrew.

Prerequisites

Ensure you have Homebrew installed.

Install Dependencies

Run the following command to install the required build tools and libraries:

brew install automake bzip2 cmake make git gpatch gnutls openssl@3 icu4c pkg-config libiconv zlib

Compilation Steps

To compile ProxySQL, you must set the following environment variables so the build system can locate OpenSSL and other Homebrew-provided libraries.

1. Set Environment Variables

export PATH="/opt/homebrew/bin:$PATH"
export PKG_CONFIG_PATH="/opt/homebrew/opt/openssl@3/lib/pkgconfig:$PKG_CONFIG_PATH"
export OPENSSL_ROOT_DIR="/opt/homebrew/opt/openssl@3"

2. Run the Build

You can now run the standard build command:

make

Or for a debug build:

make debug

Troubleshooting

Linking Issues

If the linker fails to find libssl or libcrypto, ensure that OPENSSL_ROOT_DIR and PKG_CONFIG_PATH are correctly set to point to your Homebrew OpenSSL installation.

Missing ICU Headers

The build system is configured to find icu4c via Homebrew. If you encounter errors related to ICU, ensure icu4c is installed and the Homebrew prefix is correct.

Building TAP Tests (Optional)

If you wish to run the TAP tests, you need to build the test dependencies first:

export OPENSSL_ROOT_DIR=$(brew --prefix openssl@3)
make build_tap_test_debug

This will automatically:

1. Build the main ProxySQL debug binary.
2. Download and build MariaDB and MySQL connectors (patched for macOS compatibility).
3. Build the TAP test framework.
