Due to the various number of -# minor-version numbers that can exist, and the fact that string -# comparisons are not compatible with numeric comparisons, this is not -# necessarily trivial to do in a autoconf script. This macro makes doing -# these comparisons easy. -# -# The six basic comparisons are available, as well as checking equality -# limited to a certain number of minor-version levels. -# -# The operator OP determines what type of comparison to do, and can be one -# of: -# -# eq - equal (test A == B) -# ne - not equal (test A != B) -# le - less than or equal (test A <= B) -# ge - greater than or equal (test A >= B) -# lt - less than (test A < B) -# gt - greater than (test A > B) -# -# Additionally, the eq and ne operator can have a number after it to limit -# the test to that number of minor versions. -# -# eq0 - equal up to the length of the shorter version -# ne0 - not equal up to the length of the shorter version -# eqN - equal up to N sub-version levels -# neN - not equal up to N sub-version levels -# -# When the condition is true, shell commands ACTION-IF-TRUE are run, -# otherwise shell commands ACTION-IF-FALSE are run. The environment -# variable 'ax_compare_version' is always set to either 'true' or 'false' -# as well. -# -# Examples: -# -# AX_COMPARE_VERSION([3.15.7],[lt],[3.15.8]) -# AX_COMPARE_VERSION([3.15],[lt],[3.15.8]) -# -# would both be true. -# -# AX_COMPARE_VERSION([3.15.7],[eq],[3.15.8]) -# AX_COMPARE_VERSION([3.15],[gt],[3.15.8]) -# -# would both be false. -# -# AX_COMPARE_VERSION([3.15.7],[eq2],[3.15.8]) -# -# would be true because it is only comparing two minor versions. -# -# AX_COMPARE_VERSION([3.15.7],[eq0],[3.15]) -# -# would be true because it is only comparing the lesser number of minor -# versions of the two values. -# -# Note: The characters that separate the version numbers do not matter. An -# empty string is the same as version 0. OP is evaluated by autoconf, not -# configure, so must be a string, not a variable. -# -# The author would like to acknowledge Guido Draheim whose advice about -# the m4_case and m4_ifvaln functions make this macro only include the -# portions necessary to perform the specific comparison specified by the -# OP argument in the final configure script. -# -# LICENSE -# -# Copyright (c) 2008 Tim Toolan -# -# 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.
