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:

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)

Reproduziere den Fehler mit dem Setup des static-php-cli-Pull-Requests 153 auf macOS arm64 und untersuche anschließend den im Bericht gezeigten libtool-Aufruf sowie die Art und Weise, wie er libphp.a erstellt. Die Arbeit ist abgeschlossen, wenn eine statisch gebaute libphp.a, die Erweiterungen wie ext-curl oder ext-sqlite3 enthält, erfolgreich gelinkt wird, ohne dass das Archiv extrahiert und neu erstellt werden muss.
