Invalid library on macOS when compiling libphp statically

Description

When building PHP as a static library for macOS, the resulting libphp.a file cannot be linked and the following (weird) error occurs:

ld: warning: ignoring file /usr/local/lib/libphp.a, building for macOS-arm64 but attempting to link with file built for macOS-arm64

The problem only occurs if at least one extension depending on another static library has been compiled (ex: ext-curl, ext-sqlite3...). The linking is done correctly if it's not the case, or if there are dependencies to shared libraries.

Extracting the .o file from the archive and recreating it using ar also fixes the issue:

mkdir /tmp/php-o
cd /tmp/php-o
ar x /usr/local/lib/libphp.a
ar rcs /usr/local/lib/libphp.a *.o

I suspect that it's related to libtool, and specifically this line:

/bin/sh /Users/dunglas/workspace/static-php-cli/source/php-src/libtool --silent --preserve-dup-deps --tag CC --mode=link clang -static -fno-common -Wstrict-prototypes -Wall -Wextra

The problem can easily be reproduced using static-php-cli: https://github.com/crazywhalecc/static-php-cli/pull/153

PHP Version

PHP 8.2.9

Operating System

macOS 13.4.1 (M1)

Reproduce el fallo utilizando la configuración del pull request 153 de static-php-cli en macOS arm64; después, inspecciona la invocación de libtool que se muestra en el informe y cómo crea libphp.a. El trabajo estará terminado cuando una libphp.a compilada estáticamente que contenga extensiones como ext-curl o ext-sqlite3 se enlace correctamente sin necesidad de extraer y recrear el archivo.
