27: # SYNOPSIS
28: #
29: # AX_COMPARE_VERSION(VERSION_A, OP, VERSION_B, [ACTION-IF-TRUE], [ACTION-IF-FALSE])
30: #
31: # DESCRIPTION
32: #
33: # This macro compares two version strings. Due to the various number of
34: # minor-version numbers that can exist, and the fact that string
35: # comparisons are not compatible with numeric comparisons, this is not
36: # necessarily trivial to do in a autoconf script. This macro makes doing
37: # these comparisons easy.
38: #
39: # The six basic comparisons are available, as well as checking equality
40: # limited to a certain number of minor-version levels.
41: #
42: # The operator OP determines what type of comparison to do, and can be one
43: # of:
44: #
45: # eq - equal (test A == B)
46: # ne - not equal (test A != B)
47: # le - less than or equal (test A <= B)
48: # ge - greater than or equal (test A >= B)
49: # lt - less than (test A < B)
50: # gt - greater than (test A > B)
51: #
52: # Additionally, the eq and ne operator can have a number after it to limit
53: # the test to that number of minor versions.
54: #
55: # eq0 - equal up to the length of the shorter version
56: # ne0 - not equal up to the length of the shorter version
57: # eqN - equal up to N sub-version levels
58: # neN - not equal up to N sub-version levels
59: #
60: # When the condition is true, shell commands ACTION-IF-TRUE are run,
61: # otherwise shell commands ACTION-IF-FALSE are run. The environment
62: # variable 'ax_compare_version' is always set to either 'true' or 'false'
63: # as well.
64: #
65: # Examples:
66: #
67: # AX_COMPARE_VERSION([3.15.7],[lt],[3.15.8])
68: # AX_COMPARE_VERSION([3.15],[lt],[3.15.8])
69: #
70: # would both be true.
71: #
72: # AX_COMPARE_VERSION([3.15.7],[eq],[3.15.8])
73: # AX_COMPARE_VERSION([3.15],[gt],[3.15.8])
74: #
75: # would both be false.
76: #
77: # AX_COMPARE_VERSION([3.15.7],[eq2],[3.15.8])
78: #
79: # would be true because it is only comparing two minor versions.
80: #
81: # AX_COMPARE_VERSION([3.15.7],[eq0],[3.15])
82: #
83: # would be true because it is only comparing the lesser number of minor
84: # versions of the two values.
85: #
86: # Note: The characters that separate the version numbers do not matter. An
87: # empty string is the same as version 0. OP is evaluated by autoconf, not
88: # configure, so must be a string, not a variable.
89: #
90: # The author would like to acknowledge Guido Draheim whose advice about
91: # the m4_case and m4_ifvaln functions make this macro only include the
92: # portions necessary to perform the specific comparison specified by the
93: # OP argument in the final configure script.

209: # DESCRIPTION
210: #
211: # Makes sure that bison version is greater or equal to the version

217: #
218: # Example:
219: #
220: # AC_PATH_PROG([BISON],[bison])
221: # AX_PROG_BISON_VERSION([3.0.2],[ ... ],[ ... ])
222: #
223: # This will check to make sure that the bison you have is at least version
224: # 3.0.2 or greater.

226: # NOTE: This macro uses the $BISON variable to perform the check.

533: #
534: # Of course, Automake must honor this variable whenever it calls a
535: # tool from the auxiliary directory. The problem is that $srcdir (and
536: # therefore $ac_aux_dir as well) can be either absolute or relative,
537: # depending on how configure is run. This is pretty annoying, since
538: # it makes $ac_aux_dir quite unusable in subdirectories: in the top
539: # source directory, any form will work fine, but in subdirectories a
540: # relative path needs to be adjusted first.
541: #
542: # $ac_aux_dir/missing
543: # fails when called from a subdirectory if $ac_aux_dir is relative

545: # fails if $ac_aux_dir is absolute,
546: # fails when called from a subdirectory in a VPATH build with
547: # a relative $ac_aux_dir
548: #
549: # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
550: # are both prefixed by $srcdir. In an in-source build this is usually
551: # harmless because $srcdir is '.', but things will broke when you
552: # start a VPATH build or use an absolute $srcdir.
553: #
554: # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
555: # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
556: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
557: # and then we would define $MISSING as
558: # MISSING="\${SHELL} $am_aux_dir/missing"
559: # This will work as long as MISSING is not called from configure, because

561: # However there are other variables, like CC, which are often used in
562: # configure, and could therefore not use this "fixed" $ac_aux_dir.
563: #
