When Autoconf version includes also development patch character (for example, 2.72c), such as in unreleased Autoconf versions, this now sets proper number for checking minimum required Autoconf version.

PHP buildconf
|
|
|
|
A wrapper around the autoconf and autoheader that generate files for building
|
|
PHP on *nix systems (configure and main/php_config.h.in). The configure script
|
|
is used to customize the PHP build based on the provided options and system. PHP
|
|
releases downloaded from PHP.net already include the configure script so
|
|
installing Autoconf and running buildconf is not needed. For the PHP sources
|
|
from the Git repository, buildconf is used for generating a new configure script
|
|
and required files.
|
|
|
|
SYNOPSIS:
|
|
buildconf [<options>]
|
|
|
|
OPTIONS:
|
|
-f, --force Regenerate configure files in PHP release packages.
|
|
--debug Display warnings emitted by Autoconf.
|
|
-h, --help Display this help.
|
|
|
|
ENVIRONMENT:
|
|
The following optional variables are supported:
|
|
|
|
PHP_AUTOCONF Overrides the path to autoconf tool.
|
|
PHP_AUTOCONF=/path/to/autoconf ./buildconf
|
|
PHP_AUTOHEADER Overrides the path to autoheader tool.
|
|
PHP_AUTOHEADER=/path/to/autoheader ./buildconf
