  10 #              Essentially a fresh start this time around, but for maximum
  11 #              compatibility basic code was taken from, and heavy reference
  12 #              made to, the previously unattributed wx-config from cvs.
  13 #              All the usual suspects contributed to the dicussion that led
  14 #              to this new work and likewise to the ideas and content in the
  15 #              original (which was probably influenced by gtk), among them:

  53
  54     wx-config returns information about the wxWidgets libraries available on
  55   your system.  It may be used to retrieve the information required to build
  56   applications using these libraries using --cppflags, --cxxflags, --cflags,
  57   and --libs options. And you may query the properties of this configuration
  58   using --query-{host,toolkit,widgetset,chartype,debugtype,version,linkage}.
  59
  60     NOTE:    Usage of --debug and --query-debugtype are only relevant if you
  61   have any  versions prior to 2.9 installed  and use the --version option to
  62   select an earlier version.
  63
  64     If multiple builds of wxWidgets  are available,  you can use the options
  65   --prefix, --host, --toolkit, --unicode, --static, --universal or --version
  66   to select from them.  The  --selected-config  option shows the name of the
  67   current configuration and --list  shows available alternatives which match
  68   specified criteria.  The  --utility  option returns the correct version of
  69   UTIL to use with the selected build.  The  --linkdeps  option returns only
  70   static libraries for your makefile link rule dependencies.
  71
  72     The LIBS arguments (comma or space separated) may be used to specify the
  73   wxWidgets libraries that  you wish to use. The "std" label may be used  to
  74   import all libraries that would be used by default if none were  specified
  75   explicitly, e.g. wx-config --libs core,base. The "all" label may  be  used
  76   to  import  all libraries that have been compiled which are shown  in  the
  77   list  below.  The  --optional-libs parameter should be followed by  a list
  78   of  libs that should be linked to, but only if they are available.
  79
  80   Available libraries in this build are:

 474 # From here on, we'll need to be able to figure out a delegation target.
 475 # -----------------------------------------------------------------------
 476
 477 # The rules for delegation are:
 478 #
 479 # 1. If the specification is so general that it matches the default config
 480 #    (ie. this one on a first pass), then the default config will be used
 481 #    even if other installed libs would also match the spec.
 482 #
 483 # 2. If the default config does not match, find a list of all installed
 484 #    libraries that do match.
 485 #       a. If that list is empty, the specification is incompatible
 486 #          with any installed lib.  Warn and abort.
 487 #       b. If that list contains exactly one candidate.  Delegate to
 488 #          that candidate.
 489 #       c. If the list contains multiple candidates, pass on to step 3.
 490 #
 491 # 3. Attempt to discriminate among rival candidates by their similarity
 492 #    to the default configuration (ie. this one).  If we can find a unique
 493 #    candidate in this way, delegate to it.  If not, present a list of
 494 #    options to the user and request that they disambiguate it with one or
 495 #    more additional fields.
 496 #
 497 #    To refine the specified pattern, we specialise each unbound field
 498 #    using the default value from this config file.  If that results in
 499 #    no matches, we unbind it again and try the next field.  If it still
 500 #    results in multiple matches we try binding the next field as well
 501 #    until a unique or null result again occurs.
 502 #
 503 # A more general way to look at this, is the feature specifiers are all
 504 # modifiers of the wx-config you are calling.  If you supply none, the
 505 # default for that build configuration will be used.  If you supply one
 506 # or more that the default build cannot satisfy, it will try to find the
 507 # config most like itself with the desired feature(s) enabled.
 508 # The features configured into the first wx-config called will be taken
 509 # as implicitly specified if it is necessary to disambiguate likely
 510 # candidates from the information that was explicitly provided.

 547 # partial ordering it should find the first match with the most significant
 548 # similarity to this file that unambiguously meets the user specification.
 549 # If such a match exists it will be output to stdout.
 550 #
 551 # Be careful if you modify this function.  If the pruning logic is rendered

1288 # that belong at this level of abstraction to follow.  It is
1289 # a limbo for glitches awaiting the Next Design Repair.  Ok.

1291 # With that firmly in mind, our debut dilemma is:
1292
1293 # Resource compilers.  An elusive term that covers some pretty
1294 # dissimilar concepts on various platforms.  The good news is,
1295 # each platform has only one definition of 'resource', compiled
1296 # or not, and so we can abstract that neatly to return a platform
1297 # specific invocation of the appropriate tool.  The bad news is,
1298 # windres (at least) requires knowledge of the wx header files
1299 # location(s) that cannot be predicted reliably before the call to
1300 # wx-config is made.  Currently for all known resource compilers,
1301 # we can simply return a command and some salient configuration
1302 # options in response to a request for --rescomp.  So here we
1303 # top up the options for any tools that may require information
1304 # that was only just determined in the last few machine cycles,
1305 # then output the necessary incantation for the platform.
1306 #
1307 # Most things should already be constant by the time configure
1308 # has run.  Do not add anything here that is already known there.
