If building from git, these +# features should be enabled. +# +# The POLICY parameter specifies how ax_is_release is determined. It can +# take the following values: +# +# * git-directory: ax_is_release will be 'no' if a '.git' directory exists +# * minor-version: ax_is_release will be 'no' if the minor version number +# in $PACKAGE_VERSION is odd; this assumes +# $PACKAGE_VERSION follows the 'major.minor.micro' scheme +# * always: ax_is_release will always be 'yes' +# * never: ax_is_release will always be 'no' +# +# Other policies may be added in future. +# +# LICENSE +# +# Copyright (c) 2015 Philip Withnall <philip@tecnocode.co.uk> +# +# Copying and distribution of this file, with or without modification, are +# permitted in any medium without royalty provided the copyright notice +# and this notice are preserved. + +#serial 2 + +AC_DEFUN([AX_IS_RELEASE],[ + AC_BEFORE([AC_INIT],[$0]) + + m4_case([$1], + [git-directory],[ + # $is_release = (.git directory does not exist) + AS_IF([test -d .git],[ax_is_release=no],[ax_is_release=yes]) + ], + [minor-version],[ + # $is_release = ($minor_version is even) + minor_version=`echo "$PACKAGE_VERSION" | sed 's/[[^.]][[^.]]*.\([[^.]][[^.]]*\).*/\1/'` + AS_IF([test "$(( $minor_version % 2 ))" -ne 0], + [ax_is_release=no],[ax_is_release=yes]) + ], + [always],[ax_is_release=yes], + [never],[ax_is_release=no], + [ + AC_MSG_ERROR([Invalid policy.
