221 # AX_COMPARE_VERSION(VERSION_A, OP, VERSION_B, [ACTION-IF-TRUE], [ACTION-IF-FALSE])
225 # This macro compares two version strings. Due to the various number of
226 # minor-version numbers that can exist, and the fact that string
227 # comparisons are not compatible with numeric comparisons, this is not
228 # necessarily trivial to do in a autoconf script. This macro makes doing
229 # these comparisons easy.
231 # The six basic comparisons are available, as well as checking equality
232 # limited to a certain number of minor-version levels.
234 # The operator OP determines what type of comparison to do, and can be one
237 # eq - equal (test A == B)
238 # ne - not equal (test A != B)
239 # le - less than or equal (test A <= B)
240 # ge - greater than or equal (test A >= B)
241 # lt - less than (test A < B)
242 # gt - greater than (test A > B)
244 # Additionally, the eq and ne operator can have a number after it to limit
245 # the test to that number of minor versions.
247 # eq0 - equal up to the length of the shorter version
248 # ne0 - not equal up to the length of the shorter version
249 # eqN - equal up to N sub-version levels
250 # neN - not equal up to N sub-version levels
252 # When the condition is true, shell commands ACTION-IF-TRUE are run,
253 # otherwise shell commands ACTION-IF-FALSE are run. The environment
254 # variable 'ax_compare_version' is always set to either 'true' or 'false'
259 # AX_COMPARE_VERSION([3.15.7],[lt],[3.15.8])
260 # AX_COMPARE_VERSION([3.15],[lt],[3.15.8])
262 # would both be true.
264 # AX_COMPARE_VERSION([3.15.7],[eq],[3.15.8])
265 # AX_COMPARE_VERSION([3.15],[gt],[3.15.8])
267 # would both be false.
269 # AX_COMPARE_VERSION([3.15.7],[eq2],[3.15.8])
271 # would be true because it is only comparing two minor versions.
273 # AX_COMPARE_VERSION([3.15.7],[eq0],[3.15])
275 # would be true because it is only comparing the lesser number of minor
276 # versions of the two values.
278 # Note: The characters that separate the version numbers do not matter. An
279 # empty string is the same as version 0. OP is evaluated by autoconf, not
280 # configure, so must be a string, not a variable.
282 # The author would like to acknowledge Guido Draheim whose advice about
283 # the m4_case and m4_ifvaln functions make this macro only include the
284 # portions necessary to perform the specific comparison specified by the
285 # OP argument in the final configure script.

766 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
767 # $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
768 # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
770 # Of course, Automake must honor this variable whenever it calls a
771 # tool from the auxiliary directory. The problem is that $srcdir (and
772 # therefore $ac_aux_dir as well) can be either absolute or relative,
773 # depending on how configure is run. This is pretty annoying, since
774 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
775 # source directory, any form will work fine, but in subdirectories a
776 # relative path needs to be adjusted first.
778 # $ac_aux_dir/missing
779 # fails when called from a subdirectory if $ac_aux_dir is relative
780 # $top_srcdir/$ac_aux_dir/missing
781 # fails if $ac_aux_dir is absolute,
782 # fails when called from a subdirectory in a VPATH build with
783 # a relative $ac_aux_dir
785 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
786 # are both prefixed by $srcdir. In an in-source build this is usually
787 # harmless because $srcdir is `.', but things will broke when you
788 # start a VPATH build or use an absolute $srcdir.
790 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
791 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
792 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
793 # and then we would define $MISSING as
794 # MISSING="\${SHELL} $am_aux_dir/missing"
795 # This will work as long as MISSING is not called from configure, because
796 # unfortunately $(top_srcdir) has no meaning in configure.
797 # However there are other variables, like CC, which are often used in
798 # configure, and could therefore not use this "fixed" $ac_aux_dir.
800 # Another solution, used here, is to always expand $ac_aux_dir to an

1808 # ---------------------

1810 # specify the program used to strip binaries. This is especially
1811 # annoying in cross-compiling environments, where the build's strip
1812 # is unlikely to handle the host's binaries.
1813 # Fortunately install-sh will honor a STRIPPROG variable, so we
1814 # always use install-sh in `make install-strip', and initialize
1815 # STRIPPROG with the value of the STRIP variable (set by the user).
