🐞 Compliation error on macOS 26 `cargo pgrx init`

[bpsbits-org]

I did try to run cargo pgrx init

rm -rf ~/.pgrx && \
export PKG_CONFIG_PATH="/opt/homebrew/opt/icu4c/lib/pkgconfig" && \
cargo pgrx init --pg17 download

But compilation failed:

   Discovered Postgres v13.22, v14.19, v15.14, v16.10, v17.6, v18beta2
	 Creating PGRX_HOME at `/Users/dev/.pgrx`

However when I did run command below, compilation went well:

rm -rf ~/.pgrx && \
export PKG_CONFIG_PATH="/opt/homebrew/opt/icu4c/lib/pkgconfig" && \
export PATH=/usr/bin:$PATH && \
cargo pgrx init --pg17 download

Compilation failed due to a linker error during Postgres v17.6 compilation.

Homebrew’s ar was creating invalid Mach-O archives for libpgcommon.a and libpgport.a, causing the linker error (archive member '/' not a mach-o file). Using Apple’s ar ensured valid Mach-O archives, allowing the linker (ld) to successfully build the zic binary in src/timezone.

Just for case I did run

brew update
brew upgrade
brew cleanup

and tested again.

But this did not change outcome.

The final working command:

rm -rf ~/.pgrx && \
export PKG_CONFIG_PATH="/opt/homebrew/opt/icu4c/lib/pkgconfig" && \
export AR=/usr/bin/ar && \
cargo pgrx init --pg17 download

I hope this information brightens someone's day.

Things work fine on my Mac without this fix. You might check to see if there is something odd in your RUSTFLAGS. When I tried to add export RUSTFLAGS="-C force-frame-pointers=yes" to help with debugging an issue, the linker blew up with versioning errors.
