Nightly since a488606e: macOS php configure fails "The libcurl check failed" (frameworks missing from LIBS)

[moyerdestroyer]

Environment

• spc nightly spc-macos-aarch64 (sha256 e04f9658…, built after a488606 on 2026-08-22)
• Target: aarch64-apple-darwin, macOS 14 arm64 runner
• Extensions: bcmath,bz2,ctype,curl,dom,exif,ffi,fileinfo,filter,ftp,gd,gettext,gmp,iconv,intl,ldap,mbstring,memcached,mysqli,mysqlnd,opcache,openssl,pcntl,pdo,pdo_mysql,pdo_pgsql,pdo_sqlite,pgsql,phar,posix,redis,session,simplexml,soap,sockets,sodium,sqlite3,tokenizer,xml,xmlreader,xmlwriter,xsl,yaml,zip,zlib (cli only)

Problem

Since a488606 ("fix pgsql and other polyfill libs leaking into configure"), configureForUnix() runs php's ./configure with:

'LIBS' => SystemTarget::getRuntimeLibs(),   // = '-lresolv' on Darwin

instead of the previous makeVars()['EXTRA_LIBS'], which included the macOS -framework CoreFoundation -framework CoreServices -framework SystemConfiguration flags (curl.yml declares these under frameworks).

The static libcurl.a conftest link in php's ext/curl check then fails:

checking for cURL support... yes
checking for libcurl >= 7.61.0... yes
checking for SSL support in libcurl... yes
checking for curl_easy_perform in -lcurl... no
configure: error: The libcurl check failed.

config.log shows ld: symbol(s) not found for architecture arm64 — the unresolved symbols are the CoreFoundation/SystemConfiguration references inside libcurl.a. Linux builds are unaffected (no frameworks there), which is why this only bites Darwin targets.

Workaround we use

Pass the frameworks back via SPC_EXTRA_PHP_VARS="LIBS='-lresolv -framework CoreFoundation -framework CoreServices -framework SystemConfiguration'".

Suggestion

Either include declared frameworks of resolved packages in the configure-stage LIBS, or add them to the pkg-config closure used for conftest links, so static-lib link checks succeed on Darwin without leaking the full polyfill lib set.
