PHP build system evolution

This document describes how the PHP build system evolved through time.

PHP 8.6 (in development)

...

Changelog

PHP 8.6 build system changes

Abstract

  • Minimum required libzip library version has been increased from 0.11.2 to 1.0.0.
  • Minimum required PHP version found on the host system for running scripts like build/gen_stub.php during development has been updated from 7.4 to 8.1.
  • build/gen_stub.php may now generate a _decl.h file in addition to the _arginfo.h file, if the stub declares enums and is annotated with @generate-c-enums. For each enum the file will contain a C enum. Enum values can be compared to the result of zend_enum_fetch_case_id(zend_object*).

Autotools

  • scripts/dev/update-autoconf.sh has been added to update config.*/libtool.
  • libtool has been upgraded to 2.5.4 (serial 63), which fixes many bugs. As part of the upgrade to the new libtool:
    • libtool is now spread across multiple files. phpize has been updated to handle this.
    • On macOS, libtool now uses -undefined dynamic_lookup for shared objects, instead of -undefined suppress -flat_namespace.
    • --with-pic is now --enable-pic. The old flag will result in an error.
  • Symbol HAVE_ST_BLOCKS has been removed from php_config.h (use HAVE_STRUCT_STAT_ST_BLOCKS).

Windows

  • Function SETUP_OPENSSL() doesn't accept 6th argument anymore and doesn't define the HAVE_OPENSSL_SSL_H preprocessor macro anymore.
  • Function SETUP_SQLITE3() doesn't define HAVE_SQLITE3_H and HAVE_SQLITE3EXT_H preprocessor macros anymore.
  • Added a new function CHECK_HEADER() which is intended to be used instead of the CHECK_HEADER_ADD_INCLUDE().

PHP 8.5

PHP coding standards now use the C11 standard.

Changelog

PHP 8.5 build system changes

Abstract

  • ext/phar/php_phar.h is not installed anymore.
  • ext/standard/datetime.h, ext/standard/php_smart_string.h and ext/standard/php_smart_string_public.h are not installed anymore.
  • Minimum required ICU package version (for ext/intl) has been increased from 50.1 to 57.1.
  • Minimum required SQLite library version has been increased from 3.7.7 to 3.7.17.
  • Bundled file library in ext/fileinfo has been upgraded from 5.45 to 5.46.
  • Added new extensions lexbor and uri as always enabled.
  • The SIZEOF_INTMAX_T preprocessor macro has been removed.
  • The SIZEOF_PTRDIFF_T preprocessor macro has been removed.
  • The ODBCVER preprocessor macro has been removed.
  • The --with-odbcver[=HEX]/--without-odbcver configure options have been removed.
  • The Opcache extension (ext/opcache) is now always built into the PHP binary and is always loaded. The --enable-opcache/--disable-opcache configure options have been removed.

Autotools

  • Added pkg-config support to find LDAP installation for the ldap extension. The LDAP paths can be customized with the LDAP_CFLAGS and LDAP_LIBS environment variables. When a directory argument is provided to configure option (--with-ldap=DIR), it will be used instead of the pkg-config search.
  • Autoconf macro AX_CHECK_COMPILE_FLAG updated to serial 11.
  • Autoconf macro PHP_AP_EXTRACT_VERSION has been removed.
  • Autoconf macro PHP_BUILD_THREAD_SAFE has been removed (set enable_zts variable manually).
  • Autoconf macro PHP_CHECK_SIZEOF is obsolete (use AC_CHECK_SIZEOF).
  • Autoconf macro PHP_DEF_HAVE has been removed (use AC_DEFINE).
  • Autoconf macro PHP_OUTPUT has been removed (use AC_CONFIG_FILES).
  • Autoconf macro PHP_TEST_BUILD has been removed (use AC_* macros).
Autotools configure options
  • Added new configure option --with-external-uriparser.
  • Added new configure option --enable-system-glob to use system glob() function instead of the PHP built-in implementation.
  • Library directory (libdir) is adjusted when using --libdir, and --with-libdir configure options (e.g., --libdir=/usr/lib64 --with-libdir=lib64 will set libdir to /usr/lib64/php).
  • Removed ext/odbc configure options to build against specific drivers (except for DB2) and removed special cases for those drivers. It is strongly recommended to use a driver manager like iODBC or unixODBC on non-Windows. The following configure options have been removed:
    • --with-adabas, --with-dbmaker, --with-empress, --with-empress-bcs, --with-sapdb, and --with-solid.
Changes to main/php_config.h
  • The PHP_ODBC_CFLAGS, PHP_ODBC_LFLAGS, PHP_ODBC_LIBS, and PHP_ODBC_TYPE preprocessor macros defined by ext/odbc are now defined in php_config.h instead of the build-defs.h header.
  • The HAVE_INTMAX_T preprocessor macro has been removed.
  • The HAVE_PTRDIFF_T preprocessor macro has been removed.
  • The HAVE_SSIZE_T preprocessor macro has been removed.
  • The SIZEOF_SSIZE_T preprocessor macro has been removed.

Windows

  • ext/com_dotnet is built as shared by default.
  • phpize builds now reflect the source tree in the build dir (like that already worked for in-tree builds); some extension builds (especially when using Makefile.frag.w32) may need adjustments.
  • SAPI() and ADD_SOURCES() commands now support the optional duplicate_sources parameter. If truthy, no rules to build the object files are generated. This allows to build additional variants of SAPIs (e.g., a DLL and EXE) without duplicate build rules.
Windows configure options
  • The --enable-sanitizer configure option is now supported for MSVC builds. This enables ASan and debug assertions, and is supported as of MSVC 16.10 and Windows 10.
  • The --with-uncritical-warn-choke configuration option for Clang builds has been removed in favor of adding warning-suppressing flags via CFLAGS.
Changes to main/config.w32.h
  • The HAVE_GETLOGIN preprocessor macro has been removed from configuration header (main/config.w32.h).

PHP 8.4 (2024)

Autotools-based build system has been cleaned-up, updated, and refactored using the current Autoconf syntax for the current systems at the time. Cross-compiling has been improved one step forward with cache variables synced enabling the manual overrides on many places. C preprocessor macros inconsistencies between Windows and Autotools configuration headers have been synced to a nearly identical behavior.
