# Check PHP build system tools such as autoconf and their versions.

#
# DESCRIPTION:
# Optional stampfile is for Makefile to check build system only once.

# PHP_AUTOCONF Overrides the path to autoconf tool.
# PHP_AUTOCONF=/path/to/autoconf buildcheck.sh

# Go to project root.

# Get minimum required autoconf version from the configure.ac file.
min_version=$(sed -n 's/AC_PREREQ(\[\(.*\)\])/\1/p' configure.ac)
# Check if autoconf exists.

echo " You need autoconf version $min_version or newer installed" >&2
echo " to build PHP from Git." >&2
