Thread: pgsql: Make building with LTO work on macOS
Make building with LTO work on macOS When building with -flto, the backend binary must keep many otherwise unused symbols to make them available to dynamically loaded modules / extensions. This has been done via -Wl,--export-dynamic on many platforms for years. This flag is not supported by the macOS linker, though. Here it's called -Wl,-export_dynamic instead. Thus, make configure pick up on this variant of the flag as well. Meson has the logic upstream as of version 1.5.0. Without this fix, building with -flto fails with errors similar to [1] and [2].
