29 | # AX_APPEND_FLAG(FLAG, [FLAGS-VARIABLE]) | |
30 | # | |
31 | # DESCRIPTION | |
32 | # | |
33 | # FLAG is appended to the FLAGS-VARIABLE shell variable, with a space | |
34 | # added in between. | |
35 | # | |
36 | # If FLAGS-VARIABLE is not specified, the current language's flags (e.g. | |
37 | # CFLAGS) is used. FLAGS-VARIABLE is not changed if it already contains | |
38 | # FLAG. If FLAGS-VARIABLE is unset in the shell, it is set to exactly | |
39 | # FLAG. | |
40 | # | |
41 | # NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. | |

219 | # SYNOPSIS | |
220 | # | |
221 | # AX_COMPARE_VERSION(VERSION_A, OP, VERSION_B, [ACTION-IF-TRUE], [ACTION-IF-FALSE]) | |
222 | # | |
223 | # DESCRIPTION | |
224 | # | |
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. | |
230 | # | |
231 | # The six basic comparisons are available, as well as checking equality | |
232 | # limited to a certain number of minor-version levels. | |
233 | # | |
234 | # The operator OP determines what type of comparison to do, and can be one | |
235 | # of: | |
236 | # | |
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) | |
243 | # | |
244 | # Additionally, the eq and ne operator can have a number after it to limit | |
245 | # the test to that number of minor versions. | |
246 | # | |
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 | |
251 | # | |
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' | |
255 | # as well. | |
256 | # | |
257 | # Examples: | |
258 | # | |
259 | # AX_COMPARE_VERSION([3.15.7],[lt],[3.15.8]) | |
260 | # AX_COMPARE_VERSION([3.15],[lt],[3.15.8]) | |
261 | # | |
262 | # would both be true. | |
263 | # | |
264 | # AX_COMPARE_VERSION([3.15.7],[eq],[3.15.8]) | |
265 | # AX_COMPARE_VERSION([3.15],[gt],[3.15.8]) | |
266 | # | |
267 | # would both be false. | |
268 | # | |
269 | # AX_COMPARE_VERSION([3.15.7],[eq2],[3.15.8]) | |
270 | # | |
271 | # would be true because it is only comparing two minor versions. | |
272 | # | |
273 | # AX_COMPARE_VERSION([3.15.7],[eq0],[3.15]) | |
274 | # | |
275 | # would be true because it is only comparing the lesser number of minor | |
276 | # versions of the two values. | |
277 | # | |
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. | |
281 | # | |
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/../..'. | |
769 | # | |
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. | |
777 | # | |
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 | |
784 | # | |
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. | |
789 | # | |
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. | |
799 | # | |
800 | # Another solution, used here, is to always expand $ac_aux_dir to an | |
801 | # absolute PATH. The drawback is that using absolute paths prevent a | |
