# SYNOPSIS |
|||
# |
|||
# AX_COMPARE_VERSION(VERSION_A, OP, VERSION_B, [ACTION-IF-TRUE], [ACTION-IF-FALSE]) |
|||
# |
|||
# DESCRIPTION |
|||
# |
|||
# This macro compares two version strings. 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. |

# SYNOPSIS |
|||
# |
|||
# AX_PROG_BISON_VERSION([VERSION],[ACTION-IF-TRUE],[ACTION-IF-FALSE]) |
|||
# |
|||
# DESCRIPTION |
|||
# |
|||
# Makes sure that bison version is greater or equal to the version |
|||
# indicated. If true the shell commands in ACTION-IF-TRUE are executed. If |
|||
# not the shell commands in commands in ACTION-IF-TRUE are executed. If |
|||
# not the shell commands in ACTION-IF-FALSE are run. Note if $BISON is not |
|||
# set (for example by running AC_CHECK_PROG or AC_PATH_PROG) the macro |
|||
# will fail. |
|||
# |
|||
# Example: |
|||
# |
|||
# AC_PATH_PROG([BISON],[bison]) |
|||
# AX_PROG_BISON_VERSION([3.0.2],[ ... ],[ ... ]) |
|||
# |
|||
# This will check to make sure that the bison you have is at least version |
|||
# 3.0.2 or greater. |
|||
# |
|||
# NOTE: This macro uses the $BISON variable to perform the check. |
