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.
