Original Pull Request: https://github.com/CCExtractor/ccextractor/pull/1862

State: closed
Merged: Yes

Summary

Add -system-libs flag to mac/build.command for Homebrew formula compatibility
Add CI job to test the new flag on macOS

Problem

CCExtractor was removed from Homebrew (homebrew-core) because:

The formula couldn't build with newer GPAC versions (fixed in current codebase)
Homebrew prefers using system libraries via pkg-config instead of bundled copies

See:

PR #118897 - Formula disabled (Jan 2023)
PR #158204 - Formula removed (Jun 2024)

Solution

Add a -system-libs flag that:

Mode	Includes	Sources	Links
Default (bundled)	Bundled headers	Compiles zlib, libpng, freetype, utf8proc	`-lgpac` only
`-system-libs`	pkg-config	CCExtractor only	freetype2, gpac, libpng, protobuf-c, utf8proc, zlib via pkg-config

This allows a Homebrew formula to use:

system "./build.command", "-system-libs"

Test plan

CI: build_shell job passes (default bundled build)
CI: build_shell_system_libs job passes (new system libs build)
Verify ./ccextractor --version works in both modes

Future work

Once CI passes, a new Homebrew formula can be submitted to homebrew-core using the -system-libs flag.
